Which lubricant is better to lubricate the gearbox of the corner grinder?

In one case, it is recommended to use a lubricant for a pile in combination with MS-20 oil, otherwise it is proposed to use a mixture of substances CITIMI-221 and TAD-17.

Foreign manufacturers of the tool, including angular grinder, recommend specially designed ointments as lubricants for bells. One of the common foreign lubricants is the lubricant with the marking MOS2 NLGI 2 ISOL-XBCHB 2 DIN 51825-KPF 2 K-20.

The role of lubrication and its characteristics

A distinctive feature of the corner grinder is a gearbox, which consists of gears that have a scobbeled structure. When the tool is working, this node takes on a significant load and is more worn more than others. Corner grinder rotor creates a rotational moment passing from a small gear with oblique teeth to its big analogue. The last gear has a shaft on which a working tool is attached (milling cutters, sandpaper, brush).

When moving in the teeth of the gears with friction, the temperature rises against each other. And this leads to a weakening of the metal and to the speedy wear. To prevent negative consequences, special compounds are introduced into the rubbing nodes, which significantly reduce deformation and prevent details from intensively heat.

Lubrication for electric tool gearboxes should have the following parameters:

  • Its viscosity must be no more than 800 units.
  • The strength limit exceed the indicator of 120 pascal.
  • The composition should be included in the category of refractory (over 100 ° C).
  • Have water.Repellent properties;
  • Firmly stay on the details;
  • Do not cause corrosion processes;
  • Do not contain mechanical additives.

But in addition to the gearbox, the corner grinder has two types of bearings that also need lubrication. One of them helps the electric motor. The other serves as a support for the spindle of the large gear in the gearbox. These bearings work in different conditions and different oil compositions are needed for them.

Brands and their characteristics

Tips for choosing a liquid will help to purchase high.Quality and suitable goods. The peculiarity of foreign manufacturers is that they use ointments as a basis for their products. Such masses have a special development technology. All types of liquid have different markings. Combinations of letters and numbers encrypted certain characteristics.

For example, one of the most expensive imported ointments has the following characteristics:

  • Used for molybdenum;
  • Has a second class on viscous properties;
  • ISO standards are saved;
  • In the process of lubrication development, German standards were used;
  • Belongs to type to.

For lubrication with such characteristics will have to pay expensive. It is called “Makita”. You can purchase it in tubes. The quality and duration of use can be considered the advantage of the high price. Therefore, cheaper lubricants are also presented on the Russian market. High lubricants from a foreign manufacturer increased interest in domestic products.

Russian fluids are suitable for different types of tools and are not inferior in quality. Peorators, drills, gearboxes. All of them have their own types of lubricants.

Good reviews have lithium lubricants. They repel water well, and are also designed to work at different temperatures. Organically and inorganic components contribute to condensation.

which, lubricant, better, lubricate

CITIMI-203 is used for closed types of bearings. Other bearings are better not to lubricate them.

There are also pigment lubricants, they differ in color. There is blue and dark purple lubrication VNIINP. For the first option you have to pay more than for the second. Therefore, they buy it less often. Although the quality of the products is pretty good and costs spent money.

What is needed to lubricate the peorator gearbox?

This lubricant is demanding on the temperature regime of operation. But this does not mean at all that it is impossible to use lile. There are factors when, during the use of domestic lubricating fluid, the impact force of the instrument only increases and the noise level created by it decreases. Over, this is relevant for the Chinese assembly peorator.

Users of the Chinese tool do not hope for service under warranty, and therefore operate at personal discretion from the very beginning of the operation of the peorator (or electric drill). Since the peorator of any manufacturer has its own fundamental design features

, then some single lubrication instructions simply do not. The main thing is that you have at hand:

And then, as you already understood, we act clearly according to the instructions. And remember that in any case, the peorator must be cleaned as much as possible from dust

After work. Make sure that the lubrication level is no more than the control mark. Most often, the peorator has a special container for a lubricant, that is, to make all this procedure will not be very difficult.

Lubricating the gearbox in the penarater immediately after work is undesirable, because hot parts when cold lubricant gets on them lose their physical characteristics. Squint of the drill also need to be lubricated with lithol or solidol. If the pedorator has an open cartridge, then it is advisable to process the oil seal. First you need to disassemble it and wipe it thoroughly. The applied lubricant will make it possible to extend the time of the service of the device and will protect from dust from getting into the tool. There are several types of lubricants:

Is it possible to disassemble the peorator gearbox yourself?

Great attention is required by the instrument gearbox. It is not so difficult to lubricate parts of the gearbox, but before the warranty period, it is undesirable to engage in lubrication. You will succeed in disassemble the gearbox in any case, but not everyone can collect it. It is advisable to contact a company service center with a reducer lubricant problem

Or specialized workshops. This is a rather thin job, because it is advisable to entrust it to professionals. But there are times when this nearest center is far from you, so you need to make the reducer lubricant yourself.

During disassembly, pay attention to all details. Some of them have absolutely no lubrication

This does not mean that the lubricant has already been worked out on them. Just some of the parts of the gearbox is not subjected to processing. You also do not need to lubricate them. During the disassembly, we try to remember the location of the parts as much as possible and the sequence of their disassembly. Thus, you will not have “extra” spare parts when assembling. All parts of the gearbox must be thoroughly washed with gasoline

(or virtue) and wipe it dry with a rag. Rinse the gearbox inside inside. You should not rush with the assembly: let the body dry well.

Now we make a lubricant of all parts of the gearbox and collect it in the reverse order. Do not forget that an excessive amount can also affect the performance of the tool: the gearbox heat may significantly increase.

If the pedorator began to heat up more than usual during operation, then this does not mean that there is a problem with grease. Most likely, you used the dutation mode for a very long time and the lubricant simply did not go to all parts of the penetrator in the right amount.

Another reason may be clogging holes for cooling the electric motor. In this case, the solution is one: to clean the tool from dust and transfer it temporarily to another mode of operation. If the pedorator will work for half an hour as an ordinary electric drill, then the temperature of the case will decrease significantly. The gearbox must have the same temperature in any mode

Rod and the drive of the working body

The bar has two very important functions: the first. Forms a hard frame of the entire structure, the second. A shaft passes inside the metal roller rod, which connects the working organ with the engine. By the appearance of the rod, you can determine the class of the tool, if the bar is curved. This is convenient for work, but in this case the drive is a flexible shaft, which cannot convey a large torque. If the bar is straight, a hard metal rod passes inside, it can transmit more reliably and torque. Therefore, a professional tool always has straight rods.

Lubrication. A substance of a viscous consistency necessary to reduce the coefficient of friction between the individual driving parts of the mechanisms. At the same time, it is impossible to completely remove friction, therefore, to avoid wear in the peorator gearbox, timely replacement is required. During friction, small metal particles are separated from the tool and in the form of metal dust fall into the oil. Because of this, the oil loses its properties. At the first stage, the viscosity of the substance changes, and at the second it itself is the cause of the additional wear of the tool

Viscosity is the most important parameter of oil, which is worth first to pay attention when choosing

Liquid lubricant is similar to motor oil. It can only be used in peorators with a gearbox with a sealed body. In order for the oil to be kept inside, the tool shafts are protected by sealing oil seals.

The replacement of liquid lubricant is performed through the oils, special holes with a tightly closing lid. It is characterized by high efficiency, as it is able to evenly cover the entire surface of gears and other elements.

3d printer oil and grease. Keep your 3D printer running smoothly

Also, liquid oil promotes the cooling of the gearbox, while in the case of a tool overheating, the pressure is significantly increased in the gearbox. This can lead to oil loss through the seals.

Consistent lubricant is more common. Lubrication has a thick, plastic consistency and excellent adhesion. Differs in the application of application, to replace the gearbox should be disassembled. This allows you to control the required amount of lubricant in full. At room temperature, it is quite thick and holds well on metal elements. The advantage of consistent lubrication is that its use does not require complete tightness, only the use of good gaskets and bushings is enough.

During operation, the lubricant temperature grows and it, melting, evenly covers the surface of the mechanisms. After the end of work, it cools and holds on the gears.

When choosing a manufacturer, you should adhere to one rule. The manufacturer of the oil must comply with the manufacturer of the penetrator. Almost every manufacturer develops oil based on the requirements and features of his own tool. Typically, the technical documentation of the tool indicates information about the type of lubricant recommended for use. The documentation also indicates a list of power tools for which it is suitable. Do not underestimate these recommendations, since even the slightest deviation of technical characteristics can negatively affect the performance of the tool.

Among the lubricants of domestic production, a knight can be distinguished. Produced in the Moscow region and sold in a tube weighing 100 g. Convenient to use, a narrow nose of the tube is great for applying oil to the holes of the gearboxes.

Requirements for lubricants for gearboxes angular grinder

How to lubricate the gearbox of the corner grinder, the master decides for himself on his own. There is no universal product. It is necessary to select your liquid to a certain tool. Correctly selected lubricant must meet a number of requirements, including:

  • Have resistance to corrosion;
  • Consist of natural components. Including in order not to harm the master when inhaling vapors;
  • Reduce the friction force of the gears, and, accordingly, the temperature of the heating of the tool;
  • The consistency should be thick enough to stay on the details, but with a viscosity not higher than 800 PA C;
  • The consistency is obliged to remain stable, and not change, “melts” or flow out of the mechanism when the temperature rises is the minimum drop of the drop of 120ºС;
  • Ensure the operation of the tool in the range up to 150 ºС;
  • The presence of metal impurities in the composition is not allowed;
  • Strength of at least 120 Pa;
  • Be hydrophobic, have water.Repellent properties;
  • Protect the “insides” from pollution, dust.

Overview of the lubricant for corner grinder

If you lubricate the working tool with a lithol or solidol, saving on the materials, it is likely that, ultimately, the technique will refuse to work properly, no matter how high quality it is.

Some resources argue that the preparation of a liquid that satisfies all of the above points is not difficult even at home. In one case, it is recommended to use a lubricant for a pile in combination with MS-20 oil, otherwise it is proposed to use a mixture of substances CITIMI-221 and TAD-17. Despite numerous positive reviews, in both cases the consequences can be unpredictable. The manufacturer is unlikely to take into account the possibility of refueling the gearbox of a technical product not reassigned for him.

Foreign companies recommend to masters than to lubricate the corner grinder, offering specially designed ointments. The manufacturer persistently advises the use of the funds specified in the instructions. There are really those in the Russian market, but at a fairly high price. In this regard, the question arises of high.Quality lubricants of the domestic manufacturer:

  • If molybden was in the composition of the original imported lubricant, an analogue with a macrot “MOS2” should be sought;
  • “NLGI2”-for industrial tools and others working on fluids of the second viscosity class (penentration-265-295);
  • “ISOL-XBCHB 2” for the ISO standard;
  • DIN 51825-KPF 2 K-20 for DIN standards.

Among Russian lubricants, the materials of Interskol, which has been manufacturing and maintaining the power tool for a long time, are distinguished. Such lubricants, “sharpened” to the features of the technique, provide not only the first.Class work of the gearbox and meet many stated requirements, but also pleasantly pleasing to the price. So, a tube of lubricant will cost the buyer no more than 100, while the same lithiol costs only half cheaper. If the meaning in this case is saved, or easier to pay a little more, but get a quality product is to decide each master.

Properties of lubricants

A lubricant for gearboxes is characterized by the following properties:

  • Viscosity no more than 800 pass;
  • A drop temperature of a drop of at least 120 ° C;
  • Strength of at least 120 Pa;
  • Lack of mechanical impurities;
  • Corrosion resistance;
  • High melting point;
  • Water.Repellent.

It is necessary to choose a lubricant that does not contribute to the occurrence of cuttings in the areas of contact parts.

When choosing a coating, you should focus on the condition that the lubricant for the bearing parts of the gearbox differs from the lubricant coating of the engine bearings.

Many are interested in the question. How to lubricate the gearbox of the corner grinder so as not to damage the tool and increase its effectiveness. Such types of lubricants are possible:

Many tool manufacturers strongly recommend applying a suitable lubricant when servicing to avoid negative consequences when working. When using the composition of other production, the tool is not subject to warranty repair.

It will seem to many that lubricating the gearbox with the composition of the manufacturer is very expensive. After all, the cost of such materials is quite high. In addition, there are manufacturers who do not produce lubricants.

In this case, you can purchase a lubricant for a clock, which in a wide range is present on the shelves of car shops. This material allows you to come to positive results during operation. And many use this lubrication option. However, it is worth noting that this option is the worst, in comparison with the first.

When choosing a solidol or lithola as a lubricant, there is a risk of leading a tool to a quick breakdown. This is due to the fact that these substances do not imply use at elevated temperatures and great friction. Therefore, after some time, problems may arise when working a tool.

Thus, the optimal lubrication option for angular grinder is considered the one that corresponds to the brand of the manufacturer of the tool.

The better to lubricate the gearbox of the corner grinder?

Today the corner grinder is present in the arsenal of each man. However, in addition to the convenience of use, this device requires periodic attention to its main mechanism. The gearbox. It is important to know how and how to lubricate the gearbox of the corner grinder in order to extend its service life.

Why lubricate the gearbox of the corner grinder?

During operation, the internal parts angular grinder experience significant friction, due to which wear occurs. Small metal particles are scraved, dust gets into the gearbox, all this, as accumulates, contributes to even greater wear and overheating. The lubrication of the gearbox is necessary primarily to reduce the coefficient of friction. It also improves heat sink and binds particles. In addition, lubrication increases the resistance of the metal to corrosion. Over time, depending on the frequency of the use of corner grinding, the lubricant loses its properties, and due to a large accumulation of solid inclusions, on the contrary, it can increase the wear rate of rubbing steam.

The manufacturers of the tool indicate in the technical documentation how often it is necessary to prevent the mechanism. However, the above dates are quite subjective, since it all depends on how often the angular grinder is used and how dusty the air is in the room where the device has to work.

Get Another Angle Grinder

Ready lubricants

As a rule, the manufacturer requires customers to use the products of its brand for lubrication of gearboxes of the angle grinding machine. And this is understandable. All lubricants undergo harsh tests directly at the factory of the company. The manufacturer selects the composition and manufacturing technology in such a way as to get the product that allows the maximum service life of the parts. At the same time, lubricants from the manufacturers of the tool have a drawback. High price.

Instead of oils directly from the manufacturer, it is quite possible to use high.Quality alternative options. At the same time, you should carefully read the required properties that the manufacturer described in the instructions for the corner grinder. Several popular alternative brands of lubricants: Haskey, Castrol, Liqui Moly, as well as the domestic proposal “Nanotech”.

A device whose guarantee is not yet the expiration of it is better to lubricate it with a branded product. Otherwise, when damage, the corner grinder can be refused to repair at the expense of the seller.

If desired, lubrication for angular grinder can be made by yourself. This will require plastic lubricant, for example, cyatim-221, oil (suitable for I-20), as well as a suitable metal tank for mixing and burner.

The manufacturing process is generally simple, but it is very difficult to get a homogeneous product. In plastic lubrication with constant mixing and slow warming, oil is added. In a successful case, a stable connection of two components should be obtained.

The quality of the finished composition in any case will be low, and it should not be used for long.Term work.

Carrying out the gearbox service angular grinder is quite simple, but before application it is extremely important to completely completely clear the mechanism of the old product. If this is not done, then the benefits of the new composition will be minimized.

Timely maintenance of the corner grinder is the key to the durability of its internal details.

How to lubricate the gearbox of the corner grinder and how to choose a lubricant for a corner grinder

Effective work, safety and prolonged use of any equipment depend on high.Quality and timely care. Details subject to the largest load require the most attentive attitude to themselves. Such as, for example, gearbox angular grinder.

In the process of using the tool, the design is subjected to friction, and, accordingly, overheats. Poor lubricant can, having lost the desired consistency, “leak” from the mechanism, which will entail an additional load, mechanical and temperature. It is also extremely difficult to control the volume of such a tool.

  • On the internal walls of the case are found “clips”, dry and dried particles;
  • The gear of the gearbox is not covered with lubricants in the proper amount;
  • A year has passed since the last replacement (with frequent use of technology);
  • The details of the gearbox, the rotor bearings are replaced.

If the meaning in this case is saved, or easier to pay a little more, but get a quality product is to decide each master.

Why are the elements of the pea need lubricant

The lubricant, including used for the peorator, is 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 each other. Thus, the lubricant only reduces friction, but does not completely eliminate it, so the lubricant is gradually saturated with the products of wear of rubbing parts. Metal dust. As a result, not only the viscosity of the lubricant changes, but it itself becomes the cause of more intense wear of equipment.

It should be immediately noted that it is viscosity that is the most important parameter, which must be focused on, choosing a lubricant of a certain type.

How to choose a lubricant for a specific peorator model? First of all, you need to consider the recommendations of the manufacturer of equipment, which necessarily indicates both the required type of lubricant and the frequency of its replacement. It is especially important to focus on such recommendations, has not yet expired the warranty period for the peorator. Otherwise, in the case of a breakdown of the device, you will not be able to use the warranty obligations of the manufacturer.

Many owners of the penetrators after the expiration of the warranty period begin to use not proprietary compositions for lubrication, but their cheaper analogues. Liletics or solidol. Of course, such lubricants are not able to harm the elements of the structure of the penetrator, but, using them, it should be borne in mind that they should be replaced much more often.

Lubrication replacement technology

First of all, it is necessary to completely remove the spent lubricant. Usually it, due to the presence of impurities of dust and dirt, darkens, cloudy. Next, you should carefully check the details of the tool for traces of lubrication, cavity of the case. On foreign inclusions, including particles of broken parts. For a more efficient cleaning of the angular grinder, it is recommended to use liquids used to wash the motor and its parts. Kerosene and gasoline are suitable in this number.
