Analysis of Causes of Servo Motor Failure (6)
Nine, bearing overheating
1. Cause of failure
1 too much or too little grease;
2 oil is not good enough to contain impurities;
3 bearing cooperation with the journal or end cap is not appropriate (too loose or too tight);
4 bearing inner hole eccentric, rubbing with the shaft;
5 motor end cover or bearing cover is not flat;
6 The coupling between the motor and the load is not proofed, or the belt is too tight;
7 bearing gap is too large or too small;
8 motor shaft twists and turns.
2. Troubleshooting
1 add smooth grease according to the rules (1/3-2/3 of the volume);
2 replace the clean smooth grease;
3 too loose can be corrected with the adhesive, too tightly tighten the car, grinding the journal or the inner hole of the end cap to make it suitable;
4 repair the bearing cover to eliminate the rubbing point;
5 installed from scratch;
6 proofread from the beginning, adjust the belt tension;
7 replace the new bearing;
8 proof the motor shaft or replace the rotor.
