Analysis and solution of common problems of bearing failure
Author: hongyuanTime:
Bearing is an important part of mechanical equipment, but also easy to wear parts. If the bearing fault is not repaired in time, it will lead to too large bearing clearance, which will affect the improvement of production efficiency. The following is to introduce the causes and solutions of bearing faults that often occur.
1. Bearing bending
Solution: Improper axle shoulder may cause bearing bending. It is necessary to reprocess the shaft chamfering or add shoulder clasp to eliminate stress.
2. Insufficient bearing support leads to distortion of the outer ring
Solution: Rework the chamfering of the bearing box or add shoulder clasp to eliminate stress.
3. Friction occurs between the shaft shoulder and the bearing
Solution: Rework the shoulder to eliminate friction
4. Bearing seals are deformed
Solution: Reprocess the empty shoulder of the bearing box.
5. Deformation of shaft and inner ring
Solution: Reprocess the shaft chamfering to obtain proper support.
6, bearing box and outer ring deformation, bearing extrusion
Solution: Reprocess the chamfering of the bearing box to obtain proper support.
7, rotating oil seal or dust ring friction static parts
Solution: The operating clearance of rotary oil seal and dust ring should not be too small to avoid friction and borrowing.
8, the oil level is not correct, there is no lubricant in the bearing
Solution: Clean up the blockage in the oil level table to make the oil level correct.
