Bearing clearance issue
Thread Content
May I ask, why does wear occur in the areas where the clearance of the motor shaft bearings is large, while there is no wear in the areas with smaller clearances? The large gap is 0.51 mm, and the smaller one is 0.48 mm
Misalignment or bearing assembly issues cause uneven wear of the bearings.
It should be thick-walled bearings for motor shafts. The tiles weren’t scraped properly. A large gap does not mean grinding is impossible; the lower bearing shell on the side with the larger gap may be in contact with the shaft, while the lower bearing shell on the side with the smaller gap is not in contact with the shaft. It is recommended to re-lap the lower bearing shells
Due to installation issues or foundation deformation, settlement of the foundation, etc., the levelness of the bearing housing is insufficient, exceeding the self-adjustment range of the bearing shells, which results in uneven wear! I’ve encountered this situation before!
