The most important elements of many nodes andCar units are bearings. They are intended for the necessary fastening of certain parts in space, they provide rolling, horizontal and vertical movement, and also reduce the load by transmitting it to other parts.
Для того что бы подшипники работали наиболее efficiently and reliably, they must be periodically lubricated. It should be remembered that the quality of the lubricant is the key to long and reliable operation of the entire mechanism, so you cannot save on lubrication!
Bearing lubricant contributes to:increase the efficiency of the whole mechanism and individual parts under high loads, high speeds, humidity or exposure to extreme temperatures. Choose a suitable lubricant is based on the type of bearing. So, depending on the type of friction, sliding or rolling bearings can be distinguished. The grease for different types of bearings is also different.
Support for the implementation of the rotation of partsVarious mechanisms serve as rolling bearings. The basis of their work is rolling friction. They consist of rolling elements, separator separating them, inner and outer rings. These parts can be ball, thrust, spherical, roller, etc.
Rolling bearings may be lubricated asliquid oil, and as a grease. The qualities of liquid oils include: slight resistance to rotation and good heat dissipation. They protect bearings from wear and stabilize their performance. Greases can provide good corrosion protection and can also be easily held without special sealing. Special grease for hub bearing is also available.
Support for guide units serve bearingslip. In such nodes friction occurs when sliding mating surfaces. Depending on the direction of the load, radial or axial slide bearings can be installed here. Also, depending on the type and mode of lubrication, these bearings are divided into hydrostatic, hydrodynamic, gas-static, gas-dynamic. According to another classification, they are divided into segmental, self-installing, self-lubricating, etc.
Since rolling bearings have certainadvantages over sliding bearings, they are more common. Rolling bearings lubricant may be consistent, to prevent close contact between the working elements.
It is also important when choosing a lubricant to take into account operating conditions: temperature, rotational speed, aggressiveness of the environment, load.
Properly selected bearing grease will allowyou have a very long time to exploit your car. At the same time, you can avoid significant time and financial costs, which should also be an additional bonus for choosing high-quality material.
