Causes of oil leakage of oil seal aging:
1. Reasons for assembly: When assembling, if the threads or splines are not aligned, the misplaced teeth will leak oil due to poor sealing performance, and at the same time, the oil seal itself will be damaged.
2. Material problem: The tightness of the spring does not meet the process requirements, and if it is too tight, it will cause improper fit of the rotating shaft of the oil seal and abnormal wear. When it is too loose, the pressure will be too small to be compacted, and the sealing effect will not be achieved.
3. The oil seal and the rotating shaft are not on the same axis, and eccentric wear occurs, resulting in abnormal wear of the lip.
4. If there is no grease on the lip of the oil seal, dry friction will occur, and mechanical wear will quickly grind the teeth.
