(Summary description)The plane thrust bearing mainly bears the axial load in the assembly, and its application is wide.

The plane thrust bearing mainly bears the axial load in the assembly, and its application is wide. Although the installation and operation of thrust bearings are relatively simple, errors often occur during actual maintenance, that is, the installation positions of the tight and loose rings of the bearing are not correct. As a result, the 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 journal are in transitional fit. When the shaft rotates, it drives the tight ring and rubs against the end surface of the stationary part. When subjected to the axial force (Fx), the friction torque will be greater than the resistance torque of the inner diameter fit, resulting in tightness. The matching surface of the ring and the shaft is forced to rotate, which intensifies the wear of the shaft journal.

Therefore, the following points should be paid attention to when installing the thrust bearing.

(1) Distinguish the tight ring and loose ring of the bearing (judging according to the inner diameter of the bearing, the difference in aperture is 0.1～0.5mm).

(2) Distinguish the static parts of the mechanism (that is, the parts that do not move, mainly refer to the assembly).

(3) No matter what the situation, the loose ring of the bearing should always lean against the end face of the stationary part.
