What a lubricant to fill the gearbox grinds. The procedure for applying lubrication to the gearbox of the grinder

Lubrication for the gearbox Golarka. Which one to choose?

One of the most painful issues when performing the power tool is a lubricant. This post about lubrication. I am not an expert in this area and do not earn a living by repairing a power tool. There is a golden life rule: “If you want to do well, do it yourself”.

A large number of materials on this topic have been studied and viewed. I will outline what I endured for myself. Perhaps this information will be useful to someone.

The post does not claim absolute truth and collected information published on the basis of reading many forums and Internet resources devoted to the repair of power tools.The tool accumulates. I think everyone. I have, most often brand.

When Chinese breaks, it’s easier to buy the same and not puzzle over the repair and restoration. Often. This path and cheaper. When it comes to Makita, Bosch Professional or Fein. The best option to do then. This can save a noticeable amount of banknotes in the future.

At first glance, lubrication problems. As such. Any manufacturer has a full range of lubricants for different nodes. However, not everyone can purchase them. Most often, everything rests on accessibility and price. As a result, anything goes on to the matter, including Litol and Solidol. The consequences can be extremely deplorable. The breakdown of the tool.

Everyone knows that it is desirable to use lubricants recommended by the manufacturer. The pluses are undeniable. They are checked and are guaranteed to be suitable, and there should also be no refusal of warranty repairs.

For those who, for various reasons, are ready to sacrifice a guarantee I give recommendations of service centers.

One) For the gearboxes of the majority, including not the Boshevsky instrument, is suitable Bosch grease (Small information is just below. A list of consistent lubricants, oils and ups prescribed for service operations when servicing power tools). Her high performance characteristics are not in doubt. However, she is extremely expensive. If for your tool an original (that is, recommended by the manufacturer) you can’t find, feel free to take it.

2) Also for gearboxes of such an instrument as drills, lobe, Ushm. Good Optimol Longtime2 Castrol production.

3) Of the alternative lubricants that attracted attention were the lubricants of the company Huskey.

Bosch grease turned out to be very expensive. Castrol lubricant could not be found. There are lubricants on sale with the inscription Makita, but judging by the price is some kind of incomprehensible Chinese craft. I decided to try Huskey. The originality of doubts caused. Reviews are positive. There were several dealers in Kyiv.

There are also dealers in many other countries. The support forum is available. As they say, the optimal ratio of price and quality. Universal lubricant. There was a lubricant Huskey Coolube, which successfully works in gearboxes of all types of power tools.

But for the gearbox, each type of power tool needs its own consistency of the lubrication of Huskey Coolube.

According to the codes given, these lubricants can be ordered at Bosch service centers

• Links for independent study:About grease (forum “City of Masters”)Maintenance and repair of power tools (Huskey Forum)
• Lubrication consistency. NLGI

As it turned out. You can use one and the same brand of universal lubrication. But for the gearbox, each type of power tool needs its own consistency of this very lubricant lubricant.

Classification NLGI. This is a “consistency of lubrication” or, more simply, the degree of its density. Details here Classification of plastic lubricants NLGI

The consistency depends on the speed of the gearbox rotation. The higher the speed of rotation, the less thick there should be a lubricant. NLGI consistency is indicated on the package of any lubricant.

• So that no one will ever get confused again, I report the following:
• Gearboxes of drills, screwdrivers, jigsaws, tape grinders, mixers. NLGI 2. Soft;
• Gearbox block of light perforators. NLGI 1. Very soft;
• Gearboxes of corner grinders, circular saws, motorcycle. NLGI 0. Half.Liquid;
• Reduced block of heavy perforators. NLGI 00. Liquid.
• There was only a lubricant of Huskey Coolube Nlgi 2.

It is suitable for many types of power tools. But not for all. Of the more thick, you can always make a more liquid. To do this, use Industrial oil I-20A. Most often it is contained in ordinary oils, which are sold in markets and in construction stores.

In order to get NLGI 1, you need to add about 25% of the oil from the lubricant volume.

To get NLGI 0, you need to add 35% of the oil from the lubricant volume. Then beat thoroughly until a homogeneous consistency is obtained.

The role of lubrication and its characteristics

A distinctive feature of the grinder is a gearbox, which consists of gears that have a shock.Free structure. When the tool is working, this node takes on a significant load and is more worn more than others. Ushm 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 besides the gearbox, the 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.

Is it possible to lubricate the gearbox gearbox with a lithol?

Rotor revolutions Bulgarians reach 30,000. If you apply in gearbox ordinary grease ( Litol or solidol) then, with such high speeds, there will not be practically no sense from it. Even if you fill in a complete gearbox such lubrication, then at the first inclusion Bulgarians it will smear along the walls and teeth will be dry.

You need to lubricate a new grinder, there is very little lubrication “. After buying Ushm, many home masters begin to disassemble it immediately to see the presence of lubricant in the gearbox, and be sure to add your litit. Over, add need so much lubrication that it crawls out of all the cracks.

How to lubricate the gearbox

It is inappropriate to add the missing amount of oil to the gearbox body: a good composition with already worked out, and a new lubricant loses its effectiveness faster. Therefore, when the casing of the gearbox and its case is removed and the remnants of the old lubricant are removed from the lid. First use dry rag, and then wash out traces with gasoline or kerosene. After drying the parts, a new lubricant is applied to them, while the gearbox body is filled with grease for 2/3 of its volume.

After assembling the grinder, its shaft is scrolled several times with your hands for uniform distribution of oil. Rotation should turn out uniform, without jerks and jamming. After making sure that everything is fine, they include the device on the network and start work. With timely prevention, the tool will last a long time.

Is it possible to lilet into a gearbox?

Let’s summarize. Litol and lithium.Based lubricants can use a lubricant gearbox a gasoline trimmer if he and the bar are not made of aluminum. Or if you are sure that moisture does not fall on the knot with lubrication during operation.

Thanks to high water.Repellent properties, solidols are widely used as conservation lubrication for long.Term storage of metal parts and tools, especially made of high.Speed steels. Tavot, in particular, lubricated artillery shells in order to conservation.

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

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

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.

Requirements for lubricants for Ushm gearboxes

How to lubricate the gearbox of the 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 temperature of the drip 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.

Burning lubricant review

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 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 the Russian lubricants, materials of the company Interskol, which have been engaged in the production and maintenance of power tools 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 grease will cost the buyer no more than 100 rubles, 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.

Why do elements of the punch need a lubricant

Lubrication, including the punch, 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 perforator 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 perforator. 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 perforators after the expiration of the warranty period begin to use not proprietary compositions for lubrication, but their cheaper analogues. Lidol or solidol. Of course, such lubricants are not able to harm the elements of the design of the perforator, 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 more efficient cleaning of the grinder, it is recommended to use fluids used to wash the motor and its parts. Kerosene and gasoline are suitable in this number.

Homemade mixtures

People who do not know how to lubricate the Ushm gearbox can use home.Made mixtures. Quite often, people mix several compositions together.

For example, to provide the desired level of adhesion, you can use the lubricant for CV joints. Before adding it to the gearbox, it is mixed with MS-20 oil to obtain the desired consistency.

Reducer is an important detail that is responsible for the performance of Ushm. It needs to be regularly lubricated so that the grinding machine works well. However, before doing this, you need to figure out how much oil is added and how to use it correctly.

When to change grease in a grinder

The frequency of the replacement of the lubricant depends on how often and at what loads they operate the tool. As a rule, this period is about a year. In the case of intensive operation with frequent overheating, the frequency of replacement is reduced to six months, sometimes more often.

After removing the lid, you can see two conical shocking gears: a large and small gear. Small gear is anchored and drives a large gear. Large, in turn, is planted on a secondary shaft, to which a cutting or grinding disk is attached.

Than, how and when to lubricate the ear

In corner grinding machines (Ushm), called in everyday life, the main load falls on a gear gearbox changing the axis of rotation.

Care for it is required throughout the entire period of operation, since the mechanism needs to reduce friction between its interacting details, timely maintenance.

Proper Lubrication for Industrial Gearboxes | WCHYWT #1

The use of lubricant for the grinder reducer allows not only to minimize the destructive friction effect, but also helps to cool the tool.

When you need to change the lubricant in the Ushm

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

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 grease for the grinder must be changed if there are dried lumps on the internal walls of the gearboxes or with its insufficient amount.

How much lubrication is required to replace

The required lubricant volume for Ushm is prescribed taking into account the full 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.

How to lubricate the ushm

The grease of the gearbox of the grinder is carried out in several stages.

Stage for removing the old lubricant

Removing the lubricant that has worked out. The first stage of the reducer service. Remove the old layer for several reasons:

• A spent lubricant is not able to perform his functions;
• It has small particles formed in the process of wear of the rubbing elements;
• The old lubricant will mix with the new one, because of this, the node will work incorrectly, the replacement will not bring any results.

Delete of working out is carried out using disposable paper towels, rags or a flap of fabric at hand. The removed parts of the gearbox should be thoroughly washed in a solvent or gasoline, and before installation. Dry. The remains of materials used to clean the materials are also able to mix with a new lubricant and change its consistency, which will lead to a deterioration in characteristics.

The stage of lubrication on the bearing

Gear bearings should be lubricated, clogging all available free places. The lubricant from the tube is squeezed out until its excess flow from the back. This serves as an indicator of the required level of filling.

The stage of lubrication for gearbox

The gearbox needs to be filled with such a volume of lubricant so that it completely covers the gears.

Control of the adequacy of lubrication for the Ushm gearbox is carried out on a short time. If in 3-5 minutes of operation the temperature of the assembly increased and the flow of the lubricant is observed, part of its volume must be removed. To do this, the gearbox is disassembled again, the excess is removed with a rag or a rag.

When checking, the opposite situation may be observed when a noise appeared when the Ushm appeared. This means that lubrication is not enough and it must be added.

To conduct preventive examinations, it is necessary to promote the bolts tightening the lid and visually inspect each detail. If slightly dried or completely dry areas are observed, a complete replacement of the lubricant is recommended.

What grease to choose

There are several ways to reduce the friction impact on the interacting elements of the grinder gearbox. The choice than to lubricate the friction nodes is made from the following options:

• The use of expensive special lubricants for gearboxes from known brands;
• The use of universal compounds suitable for any power tool;
• Lubrication of the gearbox with lithol or solidol;
• Using self.Made lubricants.

Application of special materials. The optimal solution. When choosing a lubricant for the gearbox, it is recommended to give preference to the compositions produced under the same brand as the Bulgarian itself. For example, if AEG machine machine, then the lubricant must buy the same brand.

When using specialized products, the service life of Ushm is significantly increased, since the manufacturer takes into account all the features and nuances of the operation of their own equipment. The minus of the use of branded materials is their high cost, which may affect the family budget.

How to lubricate the gearbox grinds?

Greetings in the next article on the site! Today we will talk about how to lubricate the gearbox of the grinder (angle grinding machine), as well as about how and when it is done.

By operating this tool, any user sooner or later faces this issue. Of course there are low.Responed people who do not follow their technique at all. And they eventually out of order before.

To avoid this, it is necessary to do certain simple procedures. For Ushm, the main such service effect is to replace lubrication in the gearbox. Yes, it is replacement, not a simple addition. I will explain below why.

Materials from foreign and domestic manufacturers

For foreign stamps of Ushm, it is recommended to use specialized compounds designed specifically for such a power tool. Most often, manufacturers of Bulgarians recommend using lubricants on which there is such a marking-MOS2 NLGI 2 ISOL-XBCHB 2 DIN 51825-KPF 2 K-20. The following information can be obtained from this marking:

• MOS. An indication of the additive material used (number 2 is molybdenum);
• NLGI2 is a viscosity class, here it is the second;
• ISOL-XBCHB 2-confirms the compliance of the materials with the ISO standard;
• DIN, KPF, K-20-confirms compliance with the German quality standard DIN;
• Figures 51825 mean that the material is classified as “k”.

This marking confirms the highest quality of the material, but such lubricants are very expensive. You can buy high.Quality oil is much cheaper, each manufacturer of the Bulgarian creates its own special lubricant, the use of which will extend the life of Ushm and guarantees the excellent work of the tool. On the market you can find compositions from Makita, Bosch, Hitachi, Redverg, Metabo, Intercker and many others.

Given the high cost of grease for power tools from foreign manufacturers, in some cases it is easier to use domestic analogues. In recent years, Russian manufacturers have been actively creating universal compositions of the highest quality that are not inferior to Western samples and suitable for a variety of tools. In addition to gearboxes and bearings of the Bulgarians, they can be used for drifts and perforators.

Bosch lubrication for gearboxes

Among all the domestic lubricants presented on the market are most popular among consumers, thanks to the best ratio of price and quality, the company’s products are used Nanotek Metalplak Electra. This company produces a number of high.Quality materials that can be selected to lubricate the nodes of any tools.

Ready lubrication

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 company more democratic to the type of materials used. What lubricant is still better? The lubricant for the gearbox of the grinder must meet certain requirements:

• The viscosity of the composition does not exceed 800 PAC;
• 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.

The industry produces many types of lubricants, including special compositions for use in gearboxes. The best results are shown by mixtures containing molybdenum disadvantage. If we talk about foreign manufacturers, Castrola and Mobile have proven themselves perfectly.

From domestic brands, MS-1000, lemol can be noted. The use of solidol, lithola or cyatim-221 does not give the desired result.

Signs of obsolescence of lubrication

Interested in how to properly grease the gearbox in the grinder, it is necessary to consider signs of obsolete lubrication. If the master disconnects the gearbox from the Ushm and looks inside, he can see obvious signs of the need to change the composition.

When working the unit, the lubricant is sprayed and settles with a dense layer on the inner walls of the case. Over time, the substance dries. At the same time, Комментарии и мнения владельцев are formed. This indicates the need to replace lubrication.

With an increase in temperature, the lubricant becomes more fluid. It can spread, leaving the gearbox mechanism. To prevent friction, its number needs to be controlled. If the gears do not have a thick layer of grease, then it’s time to change it. Otherwise, the tool will quickly fail.

Burning lubricant review

It was previously said that there are many types of lubricants from a foreign manufacturer and from domestic. Good lubricant for electric tool gearboxes is produced by Bosh. It is called “lubrication for gearboxes” and is packed in tubes of 65 grams. One such tube will be enough for several services of a grinder.

Lubrication for the gearbox of the grinder of various brands

From lubricants intended in the gearbox of grinder produced by the domestic manufacturer, you can recommend the products of the company “Nanotek”. It is called “Nanoket Metal Plok Electra” and is designed for a tool working with intensive load. As well as from domestic lubricants, a shus or cyatim-221 are widely used, however, they require preliminary preparation and, in fact, are a home-made lubricant.

Foreign lubricants

To decide how to lubricate the gearbox of the grinder, it is necessary to consider a number of expert recommendations. They argue that you should choose the oil produced by the manufacturer of technology. Such compositions are expensive. However, they have a balanced set of additives, which provide long.Term operation of the Ushm. If the user of the equipment purchases other lubricants for servicing the power tool, the warranty may not even apply to the equipment.

However, if desired, you can replace the compositions recommended by the manufacturer with similar tools. For foreign Ushm models, funds that include additives, identical to those used by the manufacturer of the grinder are quite suitable.

If molybdenum was present in the lubricant, it is necessary to purchase a composition with MOS2 marking. For the Bulgarians, which are served by the consumable material of the second viscosity class, the composition of NLGI2 is suitable. ISO standard corresponds to lubricants with ISOL-XBCHB 2 marking. If the product was made according to Germanic quality DIN quality standards, the new oil should contain in the marking the indication of DIN 51825-KPF 2 K-20.

Domestic lubricants

Considering how to smear the gearbox of domestic grilles, it is necessary to pay attention to local manufacturing compositions. Today, Russian companies offer a wide selection of such funds. They differ in affordable price.

Modern domestic materials for lubricating the Ushm gearbox are characterized by high quality. They meet high foreign standards. They are used not only in grinder, but also in other varieties of power tools.

Especially popular are the funds of the company “Nanotek Metal Plaka Electra”. However, there are other varieties of service compounds for any node of the grinder, including the gearbox.

Homemade mixtures

Situations when there was an acute need to lubricate the elements of Ushm, are not uncommon. And at the same time, as luck would have it, to get a lubricant suitable for these purposes, there is no way. Then the owner may try to make the tool with his own hands from the available materials.

To ensure the desired level of adhesion, a lubricant for car crock is taken as a basis. In addition to excellent penetrating properties, its use for operation in conditions is allowed:

• Significant loads;
• High humidity;
• Temperature fluctuations in a wide range;
• Significant heating;
• Exposure to solid pollutants.

To thin the material and obtaining the consistency necessary for the reducer, it is recommended to add oil MS-20. The liquid is based on the basis gradually, preferably with drops, with constant mixing of the formed composition with a mixer.

The use of home-made material based on “Citiam-221” with the addition of TAD-17 is no less effective.
