Thrust bearing installation considerations

Plane thrust bearing in the assembly mainly bear axial load, its wide application.
Although the thrust bearing installation operation is simple, but it is still common errors occur when maintenance, tight ring of the bearing and loose ring installation position is not correct, the results lose bearing, axis neck quickly wear.
Tight ring of inner ring and shaft neck as transition fit, when the shaft rotates driven tight ring, and end face friction with stationary parts, under the axial force (
外汇)
, there will be friction torque is greater than the inner diameter with resistance moment, locking ring and shaft mating surface forced rotation, intensifying journal wear.
Thrust bearing, therefore, when installation should pay attention to the following points.
(
1)
Distinguish tight ring of bearing and loose ring (
According to the bearing inner diameter size, aperture differ O.
1～O.
5毫米)
。
(
2)
The static distinguish institutions. (
The parts movement does not occur, is mainly refers to assembly)
。
(
3)
In any case, bearing rings should always be on stationary on the face of.
