The better to lubricate the gearbox angular grinder

Any power tool contains in its design rotating parts subject to increased wear as a result of friction. It is possible to prevent premature destruction and extend the life of the instrument if you prophylaxate the rubbing parts in a timely manner. In the corner grinder, the gear of the gearbox is susceptible to the main wear. You can reduce the harmful effect of friction by applying lubricants to the surface of parts. Consider which lubricant for a gearbox of a corner grinder is better to buy.

With intensive daily use of corner grinding, lubrication replacement in the gearbox should be carried out at least once a year. Often, users do not adhere to certain periods of preventive maintenance of the tool, and regulatory work is carried out after the manifestation of extraneous sounds during operation. This is a completely incorrect method for leaving the gearbox.

Ring during rotation, rattling indicates that the gears formed on the gears, and they will soon have to be replaced.

The prophylactic examination of the gearbox begins with the separation of its casing from the rest of the corner grinder. To do this, just unscrew the four fasteners.

The next photo shows that the lubricant in the case is present, but gathered on one side of the case, and it is not enough.

This is because the angular grinding of the grinder (angle grinding machine) works at high speeds. Under the influence of centrifugal forces, particles of oil strive to move away from the axis of rotation. With prolonged operation, the surface of the gears become completely dry, and without lubrication the metal is erased. In this case, it is enough to lubricate the gear tooths with the existing composition, then close the gearbox and work until the next prevention.

Often in the gearbox you can notice grains of oil mixed with dust. During operation, the corner grinder heats up, and these grains soften, solid particles prevent the operation of the mechanism. Such a lubricant must be replaced.

The main characteristics of the lubricant for angular grinder

In angle grinding machines, the main node subjected to the greatest loads during operation is a gearbox consisting of scooters.

The rotational moment created by the rotor of the corner grinder is transmitted from the rotor to the working tool through a small, scabbling gear to a large lobby gear. Properly selected lubricant for the gearbox significantly reduces friction and heating temperature.

In the grinder, bearings are used, which also requires periodic lubrication. This is especially true for the spindle support bearing with a large scooter of the gear.

Such lubrication is suitable, which meets not only the listed requirements, but also environmentally friendly.

Lubrices for an angle grinding machine are required to have certain characteristics and must be the required consistency by properties.

The lubricant for the gearbox angular grinder should have:

Lubrication for angular grinder should not have mechanical impurities, it is resistant to corrosion, firmly retained on lubricated details, do not melt at high temperatures, prevent the formation of bully in the places of contact of parts and of course possess water.Repellent properties.

In the corner grinding machine of any company, two types of sliding bearings are used: bearings for the electric motor and supporting bearings for the gearbox.

The selection of lubricant for bearings of the electric motor differs from the selection of lubricant for the gearbox bearing. It’s all about different working conditions.

Recommendations of foreign manufacturers

Commercial policy is cunning. Therefore, all foreign manufacturers developing power tools produce “special” lubricants only for their products. Naturally, such compounds differ significantly in the price in a large way with ordinary mixtures. But, practically, nothing serious from the latter is not distinguished.

Meanwhile, manufacturers of imported angle grinders recommend using only specialized lubrication of their production. Substantiating this by the fact that the unique developed composition significantly extends the life of the mechanisms and therefore warranty service is stretched for a longer period.

And in case of non.Compliance, conditions are denied free maintenance during breakdowns. Motivating that they arose due to the use of poor-quality and cheap lubrication. And, in order to justify the high cost of their supplies, they make expensive and rare components in the composition.

Decryption of marking, which has a proprietary lubricant for angular grinder:

  • If molybdenum is introduced as an additive, then they put MOS2 markings.
  • When they increase the viscosity class to the second, they indicate NLGI2.
  • To confirm the ISO standard, they put ISOL-XBCHB 2.
  • The German quality is indicated by DIN marking.
  • The numbers 51825 are prescribed for a special standard from Germany by type of “K”.

Literally all famous brands use such techniques. From Makita and Bosch to Hitachi and Intercommit.

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.

Recommendations of specialists

Experienced specialists give advice, the better to lubricate the gearbox of the corner grinder. They say that if it is impossible to serve the tool with proprietary grease, you can choose another composition. The 2nd in popularity in our country is a lubricant for a shock. It is in most cases used for a Russian.Made tool. Some masters choose a lubricant for a shock and for foreign corner grinders. But the quality of unique compositions will be significantly higher.

It is worse if the master preferred such compositions as Litol or solidol. These are universal means. They are not capable of serving an angular grinder reducer system. When applying them, the work of the tool will not be able to be real. At first, the difference will be inconspicuous. But over time, severe tasks in the operation of the unit may seem.

Therefore, experienced masters do not advise saving on a lubricant for a gearbox. The costs of the purchase of unique or other quality products are paid off by a long service life of the equipment.

How to lubricate the gearbox of the corner grinder

There are several options for a lubricant-chipper used. A fairly wide list of substances is used in corner grinding machines. Which of them is considered suitable in certain conditions, the user decides. Than to lubricate the gearbox?

  • Special lubricants for a particular brand or a model of corner grinders;
  • Ordinary solidol or littes;
  • Compositions suitable for any electric tool;
  • Independently made a mixture.

Each manufacturer produces certain consumables for his equipment, including lubrication. It is optimal in that it suits specific materials of the gearbox and body. It is also created taking into account the working conditions of the device. The cost may seem significant, but it is less than the cost of the new angular grinder.

Litol (solidol) available in each garage are not considered the right decision. They are not designed for temperatures to which toothed gears are heated. Therefore, the lubricant does not work, and instead of a positive effect, it creates difficulties. When working, it will be leaning from the body, and the rubbing parts will fail faster.

Universal lubricants may also not take into account certain speeds and temperatures of the gearbox. Also, this option is bad in that such a lubricant may not work for a particular steel used. A certain effect will appear, but not more than the best than from special lubricants for the grinder.

Manually created lubrication will help out with urgent need for lubrication. The basis is advised to take a car lubricant for a shrug. It is a stand to the loads, humidity, heating fluctuations. In order to obtain the desired density, oil is added-for example, MS-20. The mixture is mixed to complete mutual dissolution. Alternative: “TsIATIM” TAD-17. Different masters and thematic forums can offer a lot of compositions, which should be used with caution. Buying a new power tool, especially the professional level, will become a significant investment of funds and time. It will be cheaper to buy the appropriate composition.

What lubricant to use for the gearbox of the corner grinder, solve directly to the user. But you need to remember the main thing: all the requirements are set out in the instructions. Information can be on the site: for example, the RU tool can recommend actions and lubrication for the Makita brand.
