Application of bearings

Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

In terms of its function, it should be support, which literally means it is used to support the shaft, but this is only a part of its function. Supporting it is essentially the ability to bear radial loads. It can also be understood as being used to fix the shaft. The selection of bearings for quick and easy automation is included. It is to fix the axis so that it can only rotate and control its axial and radial movement. If the motor does not have bearings, it cannot work at all. Because the shaft can move in any direction, and the motor requires the shaft to only rotate during operation. In theory, it is impossible to achieve the effect of transmission. Moreover, bearings will also affect the transmission. In order to reduce this impact, good lubrication must be achieved on the bearings of high-speed shafts. Some bearings already have lubrication, called pre lubricated bearings, while most bearings must have lubricating oil. During high-speed operation, friction not only increases energy consumption, but also makes it easy to damage the bearings. The idea of transforming sliding friction into rolling friction is one-sided, because there is something called sliding bearings.

The lubrication methods for bearings are divided into grease lubrication and oil lubrication. In order for bearings to function well, it is first necessary to choose a lubrication method that is suitable for the conditions and purpose of use. If only lubrication is considered, the lubricity of oil lubrication has an advantage. However, grease lubrication has the advantage of simplifying the surrounding structure of bearings, comparing the advantages and disadvantages of grease lubrication and oil lubrication. When lubricating, special attention should be paid to the amount used, whether it is oil lubrication or grease lubrication. Insufficient lubrication will affect the bearing life, while excessive lubrication will generate large resistance and affect the speed.
