What’s the related matters and product usage of spherical thrust roller bearings?

spherical thrust roller bearings

Thrust roller bearings are used to support axial and radial combined loads, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this type of bearing has a low friction factor, a high rotational speed, and has a self-aligning performance.

Related Matters of spherical thrust roller bearings
1. Selection and control of thrust roller bearing chamber tolerance: After the thrust roller bearing is pressed into the thrust roller bearing, it should be flexible and unblocked. If the obvious rotation is not flexible, it indicates that the size of the shaft is too large and the tolerance is lowered. If the thrust roller bearing is pressed into the shaft and turned by hand, there is a clear "sand" feeling, which may be that the tolerance of the shaft is too large or the roundness of the shaft is not good. Therefore, it is necessary to control the roundness when controlling the tolerance of the shaft and the thrust roller bearing chamber. Many domestic manufacturers only control the tolerance and do not control the roundness.

2. Assembly method of spherical thrust roller bearings: Because the thrust roller bearing is a high-precision product, if the assembly is improper, it is easy to damage the thrust roller bearing channel, resulting in damage to the thrust roller bearing. Thrust roller bearings should have a special mold during assembly. They should not be knocked at will. When pressing the shaft, only a small circle is required. When the large circle is pressed, only a large circle is required. Air pressure or hydraulic pressure is required for assembly. The upper and lower molds should be outside the horizontal state during press-fit. If the tilting causes the thrust roller bearing channel to be damaged due to the force, the thrust roller bearing will produce a sound.
3. Prevention of assembly of foreign objects: When the thrust roller bearing is mounted on the rotor to make dynamic balance, it is easy to enter the iron scrap generated during dynamic balance into the thrust roller bearing. Therefore, it is better to load balance before loading the thrust roller bearing. . In order to facilitate assembly, some manufacturers apply some oil or grease to the thrust roller bearing room for lubrication. However, it is often difficult for the operator to control the amount if oil or grease accumulates in the thrust roller bearing room. It is easy to enter the inside of the thrust roller bearing along the shaft when the thrust roller bearing rotates. It is best not to apply oil or grease to the thrust roller bearing chamber. If it is not painted, it must be controlled not to accumulate in the thrust roller bearing chamber.
