How to lubricate the gearbox of the corner grinder? Useful tips, recommendations of masters

Corner grinding machine (angular grinding). With the help of this tool, the masters perform many operations. He, like any other equipment, requires full maintenance. Mobile elements need lubrication. For this, special tools are used.

There are several options than lubricate the gearbox of the corner grinder. The advice of experienced craftsmen will help you choose the best way. The corner grinder will work for a long time and effectively.

The role of lubrication

Manufacturers of the presented power tool in the manufacture of the tool mechanism provide mobile, rubbing parts with a special lubricant. The composition of such tools may differ. Therefore, interested in how to lubricate the gearbox of the corner grinder (“Dewalt” is this or other brand), you need to look into the instructions. The manufacturer can give a clear definition of the options for the compositions that are allowed to use when servicing equipment.

With large loads in which the equipment has to function, as well as at high heating temperatures, lubricants prevent premature wear of metal parts.

Special components allow you to remove excess heat from rubbing steam. Also, many manufacturers provide for such an important function of their means as anti.corrosion exposure. The complexity of action allows us to ensure the full operation of the tool, extend its operation for many years.

How and how to lubricate the gearbox and the cartridge of the penetrator?

Greetings on my site! This article will talk about the lubrication of the penetrator. The operation of this tool requires not only a simple careful attitude. Be sure to periodically lubricate the gearbox and cartridge.

At the same time, the gearbox, of course, is already coming from the factory. But over time, the lubricant leaks somewhere, somewhere dries. In addition, it is intended only to reduce friction, and not to eliminate it. Therefore, one way or another, and the details still rub against each other, which is why fine metal dust is gradually formed, which remains in grease.

As a result of such mixing of metal and lubricating material, the properties of the latter are gradually lost and the wear of the parts is accelerated.

Inexpensive Chinese peorators can be poorly lubricated at the factory. Experienced masters of service centers recommend after buying even a new such device to immediately disassemble it and miss it

The cartridge from the plant goes dry. Here, in fact, not the cartridge itself is smeared completely, but only its place, which is in contact with the drill, since it is in it that severe friction occurs, without reducing which the cartridge itself and the tail of the drill itself can be damaged.

So, below, consider how and how to lubricate these elements. The SDS peorator with the horizontal location of the engine will be considered, since it is they who in the vast majority of cases are used by home craftsmen, and the article is mainly written for them.

How to lubricate the peorator

Different types of lubricants are used to lubricate the gearbox and a cartridge with drill.

Lubrication for the gearbox

A special lubricant is used here, which should be called. gearbox. It can be like under the brands under which the pies themselves are produced. Makita, Bosch, Aeg, etc.D. But it can also be released by a company that is engaged in this type of product, for example, Ravenol, Shell, XADO, etc.

Some use simple lilet or salutol for these purposes. But compared to special lubricating products, they dry faster, and they do not eliminate friction as it should.

Lubrication for drills

Everything is exactly the same here. Special lubricants for this purpose are called. for drills. And are also usually produced by the same firms that are done by peorators.

For lack of special lubrication, you can use graphite. But it does not so well remove the heat from the shank, but this is important, since sometimes with prolonged work the shank happens and is flattened, which is why it is difficult to extract later.

Lubricate the gearbox

You need to disassemble the tool case. Follow the points:

  • Disassemble the cartridge. To do this, first remove the rubber ring. Then pry the screwdriver and remove the locking ring. Next, the outer casing of the cartridge is carefully removed, and then the clamping ring, ball and spring are removed.
  • Now disconnect the mode switch. This is done in different ways depending on the model. At the end of the article, I brought a certain number of links to the video, which tells how it is shot on a particular model. If there is no your unit among them, then you can see any similar one to understand the principle. And further, I think it will not be difficult for you to disconnect it and at yourself.
  • Free from brushes collector. To do this, unscrew the back cover of the case and remove the brushes.
  • Unscrew the screws that longitudinally tighten the body, and separate it.
  • Remove the gearbox along with the engine anchor.

Now thoroughly rinse the gearbox itself, as well as the inner part of its body. Washing can be carried out, for example, with gasoline.

After that, first the most responsible parts are smeared. And then the entire gearbox is completely enveloped in lubricant.

Well, it remains to collect everything in the reverse order.

Lubricate the cartridge and shank drill

This operation is very simple, so its description will be quite short.

Just take a brown lubricant and add it directly to the cartridge. Another option involves applying it to the shank followed by installing it in the cartridge nest. But no one forbids to combine these two methods for reliability.

It is necessary to ensure that the lubricant is constantly present and as necessary to add a new. If you neglect this procedure, then the tail will overheat, which will either take it off from the rest of the drill, or to flattening. Therefore, do not be lazy and add.

That’s all you need to know by the cartridge and shank.

As promised, I attach at the end of the link to the video with disconnecting the switch:

This is all the information that I have on the issue of lubrication of the penetrator. I hope it was clear and affordable. I say goodbye to this. until new meetings!

How to lubricate and assemble the Makita 2450 and 2470 peorator correctly

The assembly of any mechanism should be proceeded after careful preparation. It is necessary to prepare not only details, but also tools, place, lubricant material.

From the tools you can not do without pliers, screwdrivers, hammer, brushes for applying lubricants.

But what is the assembly scheme of the Makita 2450 and 2470?

Assembly of the Makita peorater with your own hands can be performed only if the attached instructions are observed.

lubricate, gearbox, angular, grinder

The task of the assembly process is to replace their parts that have been released with suitable and ensuring the interchangeability and performance of the tool.

Assembly of the shock mechanism

And how to assemble the shock mechanism of the Makita peorator?The shock mechanism is assembled from two knots: the shaft of the barrel with a straight line gear and an intermediate shaft with a rolling bearing.

BUT). On the barrel pos.21 put on a straightforward gear pos.19 and pressed by a compression spring pos.eighteen.For fixation, the spring is pressed by a puck 30 poses.17 and fixed with a locking ring 28 poses.16.B). To assemble the box you need to put on a ring 9 poses.25 on the shaft of a fight, pull the rubber ring pos.26, crush a metal ring pos.27.

Now we move to the opposite side of the barrel pos.21. On the other hand, the inner surface of the trunk must be greased with grease and inserted inside the assembled drummer pos.24.

Assembly of an intermediate shaft assembly

To assemble an intermediate shaft, you need a rolling bearing of poses.41 put on the shaft pos.40 teeth to the hills of the shaft, put a clutch pos on the shaft slots.39.

On the opposite side of the shaft, a scanty gear 26 poses is put on.42., Flat puck 8 poses.45, bearing 608ZZ pos.46 and stop ring 8 poses.47.The intermediate shaft is assembled.

Assembly of the reducer node

The installation of the gearbox unit is carried out on the internal case of poses.49.

By the way, there are cases when the axes jump out of the inner aluminum corps. Both axes are pressed into the housing.

To the corps pos.49 is inserted by the assembled intermediate shaft, the lever of the rolling bearing of which should fall into the hole of the cylinder hinge.

In this case, the lever of the rolling bearing.41 intermediate shaft should get into the hinge of the cylinder pos.32, and the lower bearing of the intermediate shaft in the nest in the case. This procedure is usually performed by swaying the structure until the parts are completely hit in the indicated places.

Installation of a switch of modes switch

The mode switch is designed to translate the clutch coupling pos.39 in various provisions and transmission of progressive movement to the shaft of the shock mechanism through the rolling bearing of poses.41 to the cylinder pos.32.

Assembly of the Makita 2450 Peorater Operator

On the axis of the inner case, you need to put on the lever of the switch of the mode of the poses.82, which yields a spring from above.88, crush a flat puck pos.87. Install the stop ring pos.86. And fix it.

The locking ring must be carefully fixed carefully. Turning the intermediate shaft, it is necessary to carefully check the correct operation and the free course of the cylinder in the case.

This must be done now so that it does not become clear at the end of the assembly that the assembly is assembled incorrectly.

Assembly of the shaft of the shock mechanism

First you need to lubricate the inner part of the cylinder pos.32 and insert a drummer poster into it.thirty.

Remained in the internal corps pos.49 Put a greased barrel assembly poses.21 in place, putting it on the greased cylinder pos.32.As lubricants, it is recommended to use a special lubricant developed for Makita peorators.

Lubricants are produced by several types: Makita P-08361 and Makita 183477-5 SDS-Plus.

Lubrication Makita 183477-5 SDS-Plus is recommended for the gearbox. For shanks of the drills, the lubrication of the brand Makita 196804-7 is used.

Lubrices differ in color, but have exactly the same characteristics.And what lubricants are used in the Makita 2450 and 2470 ceorator?

And here is the assembled mechanical block in front of us.

General disassembly and assembly of the Makita 2450 peorator

Check its performance, rotating the intermediate shaft and monitoring the movement of the piston in the shock mechanism. All!

Now lubricate all parts of the mechanical unit recommended by grease. Here is an example of proper lubrication on rotating surfaces.

And here is another example of generous lubrication of a mechanical unit.

So it is also allowed to apply grease. You can’t spoil the porridge!

A greased mechanical block must be closed with a plastic body pos.14 black.By applying the case from above on the knot, press the body until the node is completely fixed in it.Backwards to insert four bolts poses.10 into the case and tighten.

Now it was the turn of joining the mechanical part of the electric motor rotor.Rotor installation

The braid of the rotor gear is tightly inserted into the body of the mechanical unit and is pressed.

It remains to insert four homing screws M4 × 60 poses.57. and tighten them into the electric block housing.

Installation of electric brushes

Remove the dirt from the grooves of the brush holder and install the brushes in place, fixing them with latches.

Now is the time to check the performance of the penetrator. Connect the peorater fork to the outlet, turn on the peorator for a short time in the “Drilling” mode.

After making sure the tools, turn it off. Put the mode switch to the “blow” position. Do not insert the tool.Check the operability of the pedorator in this position.

At the same time, you checked the operation of the mode switch.

It remains to check the styling button of the speed control regulator, make sure of the reliability of contact connections and you can start installing a patch cover.

The cover is attached with three m × 4 ongoing screws of different lengths.

Connect the Poorator to the 220β network and check in all modes.Makita 2450 or 2470 Poorator is assembled and works properly!

Manufacturers of lubricants for gearboxes

Manufacturers of lubricants for power tools can be divided into two types. First of all, these are directly manufacturers of tools. They are also engaged in the development of lubricants specifically for their products. Such means include lubricant for the gearbox of the corner grinder “Makita” under the index 181490-7. This is a composition designed specifically for Japanese.made angular grinding machines, but, of course, it can be used for Bulgarians of other brands.

The basis of the segment is the products of specialized manufacturers of lubricants. Users highly value Castrola lubrication. A well.known company produces a special composition of green color for the power tool, which can also be used for a bearing group. A similar lubricant for the gearbox of the corner grinder is presented in the “Mobile” line. This is a blue XHP 222 tool that is supplied in the cabinet with a syringe shape for oil supply. For budgets, many praise the lubrication of “nanothek”. The composition is suitable as a periodic tool for maintenance of a corner grinder used in homework.

Lubrication technique

During operation, the corner grinder is important not to miss the moment when the tool requires lubrication updates. It is not always possible to determine it by external signs, so you should periodically disassemble the crankcase and directly inspect the condition of the gearbox. Lubrication will be required either in the case of the previous composition, or with its insufficient amount.

Next, you should determine which lubricant is better for the gearbox of the corner grinder of a particular model? Again, if we are talking about manufacturers of the level of Makita, Bosch, AEG, then you can trust the lubricants of the same brands. But if the corner grinder is made by a little.known Chinese company, then it is better to contact specialized manufacturers.

For lubrication, you need to disassemble the tool, remove the gearbox and clean the cleaning. How to delete the old composition will be described separately. By the time of application, a lubrication tool should be ready. an oil with a suitable nose or a syringe that is included in the kit. Apply exactly the volume that is enough to fully cover the working space without cracks.

When you need to replace the lubrication

What is the state of my (mine) angular grinder and what service she (it) needs? How to determine it? This question worries every normal owner of a single corner grinder and every normal owner of the enterprise, on the balance of which a whole park of manual power tools “hang”.

Any user of the corner grind.

Having worked with a corner grinder for several minutes, cutting off something serious, such as a strip “100 to 4”, tear off the circle from the workpiece, turn off the “machine” and listen.

  • The rotation of the circle slows down smoothly, the characteristic noise of the corner grinder becomes quieter, and finally the spindle stops, having made several almost soundless turns before. The gearbox body is barely warm. You can confidently put in the column “grease” of your “diagnostic card” and feel free to boldly clamp a new piece of iron in Titsa.
  • Slowing rotation is uneven, with “rifts”, the spindle stops without “run”. The gearbox body is very warm, almost hot. Summary: gearbox requires replenishment or replacement of lubrication.
  • The speed of rotation of the circle fixed on the spindle drops sharply. Characteristic rattling and mechanical knock are heard. Spindle stops the impetus, sometimes with the sound of a blow. The gearbox body is hot, the hand barely tolerates. Diagnosis: Perhaps it is no longer required lubrication, but a reducer repair with a replacement of gears.

Corner grinder Makita Ga 5030 with a circle. Photos all tools.RU

The process of wear of the gear of the gearbox with a lack of lubrication. “oil starvation” develops an avalanche.like:

  • The noise when working intensifies and increases in proportion to the wear of the teeth in thickness. Wear products, mixing with grease, worsen its properties.
  • Wear reaches such a value that when changes in the load (torque or rotation frequency), the tops of the tops of the teeth arise against each other. Lubricant mixed with wear products does not perform its functions.
  • With a sharp, peak overload of the “cars” of the top of worn teeth, finally meet. The lubricant of lubrication from the corner’s corners that has lost the protective properties observes indifferently how the teeth of the sliding gear are cut, the teeth of the driven are painted.

The autopsy will show the emergency destruction of the gearbox caused by a lack of lubrication.

Reference. Wear products: the smallest particles, dust formed during the friction process of surfaces. Carbon, an integral component of steel alloys, acquires a crystalline structure of diamond and extremely abrasive.

Specifications

To have an idea than to lubricate the gearbox of the corner grinder (“Interskol” is or the products of other manufacturers), it is necessary to consider the features of this tool. They affect the technical characteristics that the lubrication should have.

The main and most loaded node of the corner grinder is a gearbox. It consists of gears of a certain configuration. Proper lubricant can reduce friction, heating mobile parts. For this, the consumables must have a viscosity of not more than 800 pass. Its drop temperature should be at least 120ºС. The strength of the strength is recommended at the level of 120 PA. This allows the tool to form a strong film on the surfaces of the parts.

The lubricant should consist of components soluble in natural conditions. It should not harm the environment and human health. The funds of trusted well.known manufacturers have appropriate quality certificates, therefore it is recommended to use them to serve the tool.

Lubrication for the gearbox of corner grinder. selection and lubrication

Corner grinder, like other tools used in the household and professional activity, requires regular maintenance. Work efficiency and duration of the service life are ensured by timely maintenance. In the article, the master plumber will tell you how to independently serve such a tool popular with home masters as an angular grinding machine (corner grinder).

The term for the next replacement of lubrication depends on the loads and intensity of using the corner grinder. It is usually equal to 12 months. With everyday operation, the corner grinder with frequent overheating of the shift frequency is significantly reduced, at least six months old.

To verify the need to make a new lubricant, the gearbox needs to be disassembled by twisting the screws on its lid. Inside there is a pair of braids. The small one is anchored and used to act as a large, located on the secondary shaft. A grinding or cutting disk is attached to this shaft.

During operation, the lubricant when the gearbox moves over the walls of the case, drying out and forming large lumps over time. The material used for a long time overheats, becomes liquid and flows from the body. Therefore, its volume in the gearbox is reduced. If the gears have only a thin layer of the lubricant, its addition is required. The lubricant for the corner grinder is subject to change in the presence of dried lumps on the internal walls of the gearboxes or with its insufficient amount.

General rules for replacing a lubricant

The main module of the corner grinder is a gearbox. It is this part of the corner grinder that experiences the maximum load. The block includes different elements that contribute to rotation. Once in the tool case, the substance reduces friction. The compositions used for the angular grinder reducer make it possible to reduce the temperature indicators that occur during operation.

During the work of the corner grinder, the mixture for lubrication is gradually spreading within the body. After a while, the substance begins to dry, and lumps are formed in the work. These pieces collect particles of dust and metal, therefore, a quick replacement of the oily composition is needed. Sometimes the problem occurs due to high temperature. The lubricant heats up, flows out, and the gearbox is left without a protective mass. It is important to replace it in a timely manner.

The required volume of lubricant for angular grinders is prescribed taking into account the complete coating of oblique teeth of the gears. Excess material will be squeezed out of the case, and too small a number will not be able to ensure the correct functioning of the gearbox.

It is recommended to take the amount of lubricant laid down during the assembly of the machine at the factory as a guideline. It should be noted that with prolonged storage in the warehouse or in the store, a certain amount of lubricant may dry and decrease in volume.

Therefore, it is better to first put the material a little more than required, and make sure that the lubricant distribution after bringing the gear of the gearbox into effect. The generally accepted norm is the lubricant filling about 40% of the reducer volume.

Any tool where there are movable elements need periodic lubrication. Especially if it is actively used. With regard to angular grinding machines, the consistency and the composition of the lubricant must meet certain requirements:

The presence in the composition of solid or worse than abrasive elements will cause abrasion of the working surface and individual parts of the device. A cheap lubricant when reaching a temperature threshold of 100-120 ° C simply evaporates. Therefore, the maximum allowable values ​​of the lubricant should pay special attention, otherwise the tool in the heat of work will be left without lubrication.

A good composition protects the surface from moisture, as well as from subsequent corrosion, which means that it must have the properties repulsive water. The verified consistency allows you to maintain a lubricant on the surface: too thick the lubricant will complicate the functioning of the mechanism, and the liquid simply wars in the gearbox.

The viscosity of the lubricants for the power tool is classified according to the NLGI standard (abbreviation “National Institute of Consistent Lubricants”). The choice of a particular consistency depends on the specific model of the corner grinder, namely, the speed of rotation of the gearbox. The higher this indicator, the less density there should be a lubricant.

Classification of viscosity for power tools:

  • NLGI 00. The most liquid consistency used in heavy technology: chipping hammers, professional peorators, etc.P.
  • NLGI 0. This is a semi.liquid composition, which is just used for Bulgarians, as well as circular saws and gasoline braids.
  • NLGI 1. A sufficiently viscous consistency for use in construction peorators and medium.power drunks and drums.
  • NLGI 2. Soft variety of lubrication. Used in household jigsaws, light peorators and drums.

The required class of the lubricant must be indicated in the instructions for the equipment. If there were no documents with a corner grinder, then all the parameters of the model should be indicated on the official website of the manufacturer of the equipment.

Electric tool manufacturers advise using special compositions of their own production. Such recommendations are given, in particular, Makita and Bosch.

You can buy such funds, but their cost is quite high, and the costs are not always justified. Interskol is more affordable to the type of materials used. What lubricant is still better? The lubricant for the gearbox of the corner grinder must meet certain requirements:

  • The viscosity of the composition does not exceed 800 pass;
  • The temperature of the drops of drops from the bulk of at least 120 ° C;
  • Homogeneous composition without the presence of mechanical interspersed;
  • Moisture resistance.

Lubricant materials for the gearbox angular grinder

An angular grinding machine (corner grinder, or “corner grinder”) is designed for cutting, grinding and cleaning products from stone, metal and other materials.

The movable parts of the corner grinder during the operation of the tool are subject to intensive wear. The bearings of the anchor and gears, as well as the gears themselves, located in the gearbox, are covered with grease at the factory, but over time it is aging and losing its properties.

To avoid premature failure of the parts, it is necessary to periodically clean the bearings and gears, as well as update the lubricant.

The fact that it is time to do this is evidenced by increased vibration of the tool and extraneous noise during its operation.

Lubricants for corner grinders should not:

  • Contain solid particles that can cause painting mobile parts of the mechanism
  • Lose viscosity and become liquid at temperatures less than 120 ° C.
  • Absorb moisture

On the details of the lubricants should form a strong film that protects them from corrosion and wear.

The consistency or viscosity of materials according to NLGI (National Lubricating Grease Institute) is selected depending on the speed of the gearbox rotation, the higher it is, the more liquid there should be a lubricant. For angular grinding mash (as well as circular saws and motorcycle), classes of class NLGI-0, half-life consistency are recommended.

Almost all world manufacturers of angle grinders recommend using only materials manufactured under their own brand for their maintenance. In this case, they can guarantee long.term and correct operation of the tool.

However, a significant drawback of branded lubricants is their high price.

Original oils and lubricants may well replace products with similar characteristics, which are represented quite widely in the modern market.

So, the materials of Haskey, Castrol, Liqui Moly and other brands are great as a lubricant for a gearbox of corner grinding.

Good lubricant for electric tool gearboxes is produced by Bosh. It sets in tubes of 65 grams, one is enough for several maintenance corner grinders.

Manufacturers do not lag behind foreign and offer their products. Very popular is the lubricant for the conical gearbox angular grinder “Nanoles Metalplak Electra”.

From domestic lubricants, a shreus or cyatim-201, but they require preliminary preparation and, in fact, are home-made lubricants.

DIY lubrication for gearbox with your own hands

Do.it.yourself lubricant for the gears of the corner grinder consists of the base and diluent.

The basis is usually a russian with disulfide molybdenum or cyatim-201. They belong to the second viscosity class according to NLGI, therefore, for use in the gearbox, they are diluted.

It is best to use simple mineral industrial oil as a diluent-for example, I-20. To obtain viscosity NLGI 0, it will be necessary to mix the composition in the proportion of the base and the diluent of approximately 70 to 30.

There are three disadvantages of such home.made lubricants:

  • Low viscosity: heated, they flow from the gearbox through the gap between the lid and the spindle
  • Additives aggressive to non-ferrous metals: Bulgarian gearbox houses are made of aluminum alloys, some models have spindle bronze-graphic bearings
  • Low moisture resistance, hygroscopicity: gearboxes of Bulgarians do not have hermetic seals

How to lubricate and assemble the Makita 2450 and 2470 peorator correctly

The assembly of any mechanism should be proceeded after careful preparation. It is necessary to prepare not only details, but also tools, place, lubricant material.

From the tools you can not do without pliers, screwdrivers, hammer, brushes for applying lubricants.

But what is the assembly scheme of the Makita 2450 and 2470?

Assembly of the Makita peorater with your own hands can be performed only if the attached instructions are observed.

The task of the assembly process is to replace their parts that have been released with suitable and ensuring the interchangeability and performance of the tool.

Assembly of the shock mechanism

And how to assemble the shock mechanism of the Makita peorator?The shock mechanism is assembled from two knots: the shaft of the barrel with a straight line gear and an intermediate shaft with a rolling bearing.

BUT). On the barrel pos.21 put on a straightforward gear pos.19 and pressed by a compression spring pos.eighteen.For fixation, the spring is pressed by a puck 30 poses.17 and fixed with a locking ring 28 poses.16.B). To assemble the box you need to put on a ring 9 poses.25 on the shaft of a fight, pull the rubber ring pos.26, crush a metal ring pos.27.

Now we move to the opposite side of the barrel pos.21. On the other hand, the inner surface of the trunk must be greased with grease and inserted inside the assembled drummer pos.24.

Assembly of an intermediate shaft assembly

To assemble an intermediate shaft, you need a rolling bearing of poses.41 put on the shaft pos.40 teeth to the hills of the shaft, put a clutch pos on the shaft slots.39.

By the way, there are cases when the axes jump out of the inner aluminum corps. Both axes are pressed into the housing.

To the corps pos.49 is inserted by the assembled intermediate shaft, the lever of the rolling bearing of which should fall into the hole of the cylinder hinge.

In this case, the lever of the rolling bearing.41 intermediate shaft should get into the hinge of the cylinder pos.32, and the lower bearing of the intermediate shaft in the nest in the case. This procedure is usually performed by swaying the structure until the parts are completely hit in the indicated places.

Installation of a switch of modes switch

The mode switch is designed to translate the clutch coupling pos.39 in various provisions and transmission of progressive movement to the shaft of the shock mechanism through the rolling bearing of poses.41 to the cylinder pos.32.

Assembly of the Makita 2450 Peorater Operator

On the axis of the inner case, you need to put on the lever of the switch of the mode of the poses.82, which yields a spring from above.88, crush a flat puck pos.87. Install the stop ring pos.86. And fix it.

The locking ring must be carefully fixed carefully. Turning the intermediate shaft, it is necessary to carefully check the correct operation and the free course of the cylinder in the case.

This must be done now so that it does not become clear at the end of the assembly that the assembly is assembled incorrectly.

Assembly of the shaft of the shock mechanism

First you need to lubricate the inner part of the cylinder pos.32 and insert a drummer poster into it.thirty.

Remained in the internal corps pos.49 Put a greased barrel assembly poses.21 in place, putting it on the greased cylinder pos.32.As lubricants, it is recommended to use a special lubricant developed for Makita peorators.

At the same time, you checked the operation of the mode switch.

It remains to check the styling button of the speed control regulator, make sure of the reliability of contact connections and you can start installing a patch cover.

The cover is attached with three m × 4 ongoing screws of different lengths.

Connect the Poorator to the 220β network and check in all modes.Makita 2450 or 2470 Poorator is assembled and works properly!

Lubricant for the Makita Peotor gearbox

The lubrication of the gearbox is not the drill for the peorater: the correct care of the inventory

The lubricant for the peorater allows you to extend the service life of its service do not make its use more effective.

So that the effect of lubrication brings the expected results, when choosing it, you should take into account not only the properties of the lubricant, but the technical characteristics of the device that is planned to use it.

When choosing how to lubricate the peorator, you need to have because of the fact that different parts of such equipment need different types of lubricants.

True lubrication of the peorater gearbox

Many people believe that the presence of lubrication on the mobile elements of the penetrator allows you to postpone its substitution for a couple of years. Although this worldview is strongly incorrect, not with the aim of changing it, it’s enough to get acquainted with the principle by which lubricants work.

Why are the elements of the pea need lubricant

A lubricant, including the pedorator used, is actually a viscous substance, the use of which is necessary to reduce the friction coefficient between the elements of the design of the mechanical device moving relative to themselves.

Such a macar, lubricant only reduces friction, but does not save it quite, therefore the lubricant is evenly saturated with the products of wear of rubbing parts. iron dust.

At the end, not only the viscosity of the lubricant changes, and additionally it itself becomes a prerequisite for more saturated wear of equipment.

It should be immediately noted that specifically viscosity is a more fundamental parameter, which needs to be navigated, choosing a lubricant of a certain type.

Over time, the lubrication is polluted does not lose its characteristics

How to correctly choose a lubricant for a specific model of the penetrator? In the main thing, it is necessary to take into account the advice of the manufacturer of equipment, which certainly shows as the required type of lubricant, so not the frequency of its substitution. In particular, it is fundamentally focus on such advice, yet the warranty period for the peorator has not expired. In another way, if the passage of the breakdown of the device is unrealistic to use the manufacturer’s warranty duties.

Surely the owners of the penetrators after the expiration of the warranty period begin to use not branded compositions for lubrication, but their cheaper analogues. lilest in otherwise solidol. This, such lubricants are not able to harm the elements of the structure of the penetrator, but, using them, should be due to what to make their substitution should be much more often.

Gear lubrication

The peorater gearbox is a more complicated device in design, because it asks for special attention to himself.

It is not difficult to make a lubricant of the gearbox of the penetrator, but independent assembly for the previously disassembled node causes severe difficulties.

If the pedorator is still under warranty, then with a question on lubricating its gearbox, it is much better to contact a specialized workshop, which provides after the after.sales service of such equipment.

The detailed diagram of the device of your peorater will help to understand the mechanism not correctly assemble the tool

In this case, the poosor of which you are, the discs or cassettes of warranty in otherwise, the warranty period for your equipment has already expired, and the authorized service center is quite distant, naturally lubricate the gearbox without the help of others, observing the highest accuracy not vigilance. For this purpose, you will need:

  • a set of locksmith tools, using which for you you will have to assemble not to disassemble the peorator gearbox;
  • unsuccessful rags;
  • The composition itself for lubrication.

It is better if a corporate remedy specially created for the equipment of a certain brand will act for lubrication. So, this will like a lubricant for the Makita peorator or a lubricant for the Bosch peorator. If you do not have branded lubricant, but it does not work to purchase it, you can use inexpensive domestic lubricants.

It is very important that you have an instruction for a peorator that you are going to lubricate. Naturally, if you are the owner of the Makita or Bosch peorator, this should be the instructions for the technique of these brands.

All the details of the gearbox should be completely cleaned of the old lubricant

Having carefully studied the instructions for the peorator, you can proceed to the procedure for lubricating its gearbox.

  • Before disassembling, the peorator should be well cleaned of dust.
  • When performing the disassembly of the gearbox, it is advisable to immediately remember how the elements of its design are located in it. At the same time, it must be borne in mind that to disassemble and lubricate the gearbox immediately after the end of the use of the peorator is not recommended. This is explained by the fact that still hot parts of the gearbox when a cold lubricant gets on them can lose their physical characteristics.
  • After all the components of the gearbox are extracted from its case, they should be thoroughly washed with gasoline or spindle oil and wiped dry.
  • The inside of the gearbox body must also be washed, wiped (as far as possible) and let it completely dry.
  • When disassembling the peorator gearbox, you can pay attention to the fact that on some elements of its design there is no lubricant. This means only that such details do not need lubrication and there is no need to apply it to them.
  • As mentioned above, it is better to use proprietary lubricant for a drill gearbox or a pedorator, which differs a number of advantages. In particular, branded lubricants retain their initial characteristics much longer, so they can be used much less often. In addition, the corporate lubricant has such an important quality as water resistance, so it effectively protects the metal parts of the penetrator from moisture and, accordingly, from corrosion. As a good alternative to proprietary lubricants for the peorator or drill gearbox, you can use Metabo oil, the cost of which is quite affordable.
  • After lubrication of all elements, the gearbox must be carefully assembled, observing the reverse sequence.

DIY gear lubrication of gearbox

In this article we will try to answer two questions.

The first, interested in the most restless, enterprising, thirsty for the discoveries of the owners of the Bulgarians. how to make a lubricant for the gearbox for a corner grinding machine? The second, which matters for curious, possibly inexperienced users. how and how to properly grease the gearbox of the corner grinder?

Homemade lubricant for gearbox angular grind

Where did the widespread opinion come from that modern lubricants are not entirely good, even unsuccessful? Who said that the lubricant produced by more than a dozen enterprises and scientific and production associations for gear gears of manual power tools are of such low quality that it is necessary to immediately invent and make a new lubricant yourself ?

In the videos posted on the pages of some sites, unknown qualifications, specialists question the quality of existing lubricants for conical gearboxes of direct.toothed, lobby and hypoid engraving used in the structure of angular grinding machines. Smoke, for example, Bosch VP729, a specialist immediately, before your eyes, prepares his miraculous composition with incredible properties.

At the same time, the entire technical arsenal of its research laboratory is used: a workbench in the garage, plastic and tin jars, a wooden stick from Eskimo. The recipe is simple and available to every trusting user. It is proposed to take some plastic lubricant and make it “older”, mixing with some kind of oil.

Components. finished materials produced by industry. Mixing equipment. jar and wand. The stability of the required temperature is provided by the candle. Product quality is evaluated by organoleptic methods. There are no test stands due to the lack of tests.

A brief description of the process: in plastic cyatim-221, industrial oil I-20 is added by drop. With continuous stirring with a stick. Cyatim-221 is made on a silicon basis from silicone oil with complex calcium thickener.

I-20 oil is a product of oil processing, which has a mineral basis. Interfere more thoroughly to get a stable polymer connection with inorganic substance.

If this succeeds, you will not only have a home.made lubricant for corner grinders, but also an international prize in the field of chemistry.

However, there are a slightly different nature on the network and videos. “When the question arose, how to lubricate the corner grinder, I remembered that in the garage I have an iron bank that remained from my father”. The bank is demonstrated. “On her is the inscription: lubricant 158”. Close.up inscription.

“I lubricated the gearbox with this grease”. This is followed by lubrication paintings, and test frames. “Now my corner grinder works like this”. Indeed, the corner grinder works quietly, evenly, after turning off, spindle speeds are smoothly falling, the machine stops almost soundless.

Pay attention: he did not invent anything, did not mix, he applied the finished product, perhaps an analogue. He does not advise, but shares his experience. What prevents you from adopting this valuable experience?

It is worth it or not to bother, the pros and cons of

Before you start making home.made lubrication, speculate about whether such a lesson makes sense? What is the extreme need to ignore the recommendations of the manufacturer and fill out the gearbox of the grinder of the “self.packal” mixture of components originally intended for other mechanisms?

The close analogue of the gearbox of the corner grinder is a hinge of equal angular velocities (shock), a responsible node of the front.wheel drive car.

Transfers high torque in complex temperature parameters, with a high speed of rotation. The details of the working hinge are in contact with each other in conditions that lead, in the absence of a lubricant film, to local welding.

By the way, the same effects arise in the brackets or hypoid gears.

There were times when many set out to replace the factory lubrication of a homemade spum. The most common recipe was simple and affordable.

We take Litol-24 and generously add friction modifier, for example, molybdenum disulfide (now sold in the fields of auto chemistry, inexpensive). Of course, mix thoroughly with a wooden stick.

Heat the mixture and insert into the hinge with a syringe, piercing the rubber cover with a needle.

Such “useful” tips were very popular in the former USSR in the late 80s, when the first VAZ “eights” and “nine” were faced with the problem of lubrication. Rather, with a lubricant deficiency for them. And there were those who followed such advice, and then shared their experience. Very sad experience.

What extreme, inexorable need requires the use of homemade (surrogate) lubricants? If in the midst of work your angular grinder categorically required grease, apply any plastic lubricant available at hand.

Litol-24 and cyatim-221 (preferably 221F) are suitable. The solidel of the USS would also come up, but, fortunately for the corner grinder, it is no longer released. We repeat. any plastic lubricant is suitable, but it must be evaluated not as an analogue, but as a surrogate.

In this case, you will have to perform all procedures to remove the residues of the existing lubricant from the gearbox. Without bothering about the absence of antifriction and outfit additives in surrogate, end the corner grinding of emergency work. Finally cut this corner or sheet of corrugated board.

Or a crumpled wing of a car, the steep owner of which demanded: “so that it was ready by morning”. After that, go to look and purchase an original lubricant or a quality analogue from other manufacturers. Remember that the accepted measure is temporary, caused by extreme necessity.

Lubrication of the gearbox of the corner grinder Makita

What lubricant is needed for the Bulgarian gearbox

Corner grinding machines (SShP), in other words, grinding machines in modern structures allow you to make complex tasks of processing hard materials. This is achieved by the method of increasing the tool of the tool not using a strong element base.

An increase in the number of revolutions also causes an increase in loads on the electric motor. The weakest location of the power plant of such an instrument is a gearbox. It is often replaced not repaired even during operation approximately working hours.

High.quality lubricant for the Bolgarki gearbox allows you to extend the operating time of technical filling, but only with the right choice.

Gear lubrication tasks for gearboxes

In order to realize why the Bulgarians need lubrication, you need to realize how the gearbox is developed. a more sensitive, but responsible mechanical part of the tool. The gearbox is formed by a whole complex of small elements and details, which are enclosed in the crankcase.

During operation, the gear actively interact with each other in conditions of direct contact with the generation of excess heat. Accordingly, the lubricant for the Bolgarki gearbox primarily protects the mechanism from wear, deformation and various damage.

The main effect of protecting such devices is provided by antifrictions. This function involves minimizing friction between parts, which increases their resource and generally enhances technical and physical qualities. In addition, the lubricant must ensure heat removal.

Some compounds create a cooling effect, but in most cases the thermal protection of the elements is supposed.

Necessary lubricants

To perform the above functions, the lubricant must have an appropriate set of characteristics.

Among the main parameters by which you can evaluate the possibilities of lubrication of gears, it is worth mentioning strength, falling point and viscosity. The power characteristic is directly responsible for the antifriction function.

That is, he will determine how much the formed film on the surface of the part can maintain its integrity.

On the question of which lubricant to use for the Bolgarki gearbox in strength can be considered values ​​of 120-150 PA. There are also compositions with a strength of more than 400 Pa, but such high indicators are not necessary. especially since the growth of this parameter inevitably minimizes other important characteristics.

As for the maximum point of the fall, you can give preference to products designed for 150-180 ° C, although this indicator depends on the requirements of a specific gearbox. Also with viscosity. A significant part of the choice of the optimal indicator depends on the recommendations of a particular manufacturer, but more often they advise viscosity at a level of not more than 800 pes.

Manufacturers of lubricants for gearboxes

Manufacturers of lubricants for power tools can be divided into two types. First of all, these are tool manufacturers. They are also developing lubricants for their products.

These include transmission lubrication of the Bulgarian “Makita” under the index of 181490-7.

This composition is designed specifically for Japanese.made angular grinders, but, of course, it can be used for the Bulgarians of other brands.

How to lubricate the Bulgarians? (Igor Nekoda)

What and how to lubricate the Bulgarian. Lubrication for continuous operation of an angular grinding machine.

The basis of the same segment is the production of specialized manufacturers of lubricants. Users evaluate Castrol grease. A well.known company produces a special green connection for a power tool, which can also be used for a group of bearings.

A similar lubricant for the Bulgarian gearbox is presented on the “mobile” line. This tool is already blue XHP 222, which is supplied in cabinets with a syringe shape for oil supply. For the budget, many people welcome NanoTech lubricants.

The composition is suitable as a periodic means of servicing the Bulgarian language used in homework.

Lubrication application technique

In the process of EWM, it is important not to miss the moment when the tool requires lubrication updates. To determine that this is not always possible by external signs, so you must periodically disassemble the crankcase and directly check the condition of the gearbox. Lubrication will be required either in the case of drying the previous composition, or if its number is not enough.

Then determine which lubricant is best suited for the gearbox of the Bulgarian specific model? Again, if we are talking about manufacturers of the level of Makita, Bosch, AEG, then we can trust the lubricants of the same brands. But if USM is produced by a little.known Chinese company, then it is better to contact specialized manufacturers.

For lubrication, you need to disassemble the tool, remove the gear and clean it. How to delete the old composition will be described separately. During application, a lubricant should be prepared. a fat cup with a suitable nose or syringe supplied with the product. Attach exactly as much as enough to cover the entire working space without cleft.

Removing the old lubricant

Well, if the old lubricant has dried up and does not present a problem for removal. In extreme cases, you may need to collect scattered parts of the composition on the body, but if the product retains your condition, you will have to prepare a solution of kerosene or gasoline.

If you moisturized a napkin or rags, carefully select the entire volume of the old lubricant from the groove. Then repeat the procedure until the surface is completely cleaned. If a lubricant is used to reduce a calf with a lower threshold of thermal endurance, you can use a hot hair dryer. He will melt the lubricant in a liquid state.

Then you only need to rinse the gearbox and dry it to apply a new composition.
