Causes and elimination of overheating faults in servo motor bearings
1. Cause of failure

1 too much or too little grease;

2 oil quality is not good with impurities;

3 The bearing is not properly matched with the journal or end cap (too loose or too tight);

4 The inner hole of the bearing is eccentric and rubs against the shaft;

5 The motor end cover or bearing cap is not flat;
6 The coupling between the motor and the load is not corrected, or the belt is too tight;

7 bearing clearance is too large or too small;

8 The motor shaft is bent.

2. Troubleshooting

1 Add grease according to the regulations (1/3-2/3 of the volume);

2 Replace the cleaned grease;

3 Over-loose can be repaired with adhesive, over-tightening the car, grinding the journal or the inner hole of the end cap to make it suitable;

4 Repair the bearing cap to eliminate the rubbing point;

5 reassembly;

6 Recalibrate and adjust the belt tension;

7 Replace the new bearing;

8 Correct the motor shaft or replace the rotor.
