1. It is not clean or the grease added is not clean. It will increase the wear, vibration and noise of the bearing, and cause the bearing raceway to be damaged, causing excessive temperature rise and burning the bearing.
2. Because of the excessively high operating temperature of the motor body, and the lack of oil in the bearing and the lack of grease in the bearing in time, the bearing may even be burned. The mixing of different greases can also cause damage to the bearing.
3. When installing the motor end cover, uneven knocking causes the end cover bearing chamber and the outer ring of the bearing to fit too loosely, causing the outer ring to run away.
4. The non-operation of the harmonic reducer for a long time has caused the grease to deteriorate and the bearing is rusted.
5. Due to the manufacturer's problem, the bearing clearance of the harmonic reducer is too small or too large. If the clearance of the bearing is too small, it will be too tight when rotating; if the clearance of the bearing is too large, it will cause abnormal noise. Both cases will accelerate its damage.
6. The bearings of the harmonic reducer are affected by the extra load.
