What is the working principle of thrust race bearing?

The working principle of thrust race bearing
Thrust race bearing is a separable bearing. The shaft ring and seat ring can be separated from the cage and steel ball/roller components.

The shaft ring is a ferrule that matches the shaft, and the seat ring is a ferrule that matches the bearing seat hole, and there is a gap between the shaft and the shaft;

The role of thrust race bearing: In terms of its role, it should be support, that is, it is used to support the shaft literally, but this is only part of its role. The essence of support is to be able to bear radial loads. It can also be understood as it is used to fix the shaft.

Thrust race bearing can only bear axial load, one-way thrust ball bearing can only bear axial load in one direction, and two-way thrust ball bearing can bear axial load in two directions;

Thrust race bearing cannot limit the radial displacement of the shaft, and the limit speed is very low. The one-way thrust ball bearing can limit the axial displacement of the shaft and the housing in one direction, and the two-way bearing can limit the axial displacement in two directions.

The lubrication method of thrust race bearing is divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, it is necessary to choose a lubrication method suitable for the conditions of use and the purpose of use. If only lubrication is considered, the lubricity of oil lubrication is dominant.

Extended information:
Although the installation and operation of the thrust race bearing are relatively simple, errors often occur during actual maintenance, that is, the mounting positions of the tight and loose rings of the bearing are not correct. As a result, the thrust race bearing loses its function and the journal is quickly worn out.

The tightening ring is installed on the end face of the stationary part, that is, wrong assembly. The inner ring of the tight ring and the shaft journal are in transitional fit. When the shaft rotates, the tight ring is driven and friction occurs with the end surface of the stationary part. When subjected to an axial force (Fx), the friction torque will be greater than the resistance torque of the inner diameter fit, resulting in tight The matching surface of the ring and the shaft is forced to rotate, which intensifies the wear of the shaft journal.
