Precautions for installation of thrust ball bearing

In the assembly process of thrust ball bearing, plane thrust bearing is mainly used to bear axial load. Although the installation operation of thrust bearing is simple, the installation operation of thrust ball bearing is relatively simple, but errors still often occur in actual maintenance, that is, the installation position of tight ring and loose ring of bearing is incorrect, resulting in bearing failure and rapid wear of journal. The tightening ring is in transition fit with the axis neck to make the journal wear and fall off quickly.
When the shaft rotates, the inner ring of the tightening ring and the journal make a transition fit, which drives the tightening ring to friction with the end face of the stationary part. When the shaft rotates, it drives the tightening ring to friction with the end face of the stationary part. When the axial force (FX) acts, the friction torque generated is greater than the inner diameter matching resistance torque. When the axial force acts, the friction torque generated is greater than the inner diameter matching resistance torque, which leads to the forced rotation of the tightening ring, Increase journal wear.
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. Judge according to the inner diameter of the bearing, and divide the bore diameter of the tight ring and loose ring of the bearing into 0.1 ~ 0.5mm respectively, with a difference of 0.1 ~ 0.5mm)
2. Static block of separation mechanism (i.e. no moving parts, mainly refers to the static block equipped with separation mechanism).
3. In any case, the loose ring of the bearing should always rest against the end face of the fixed part.
