Tips: Bearing Maintenance for Electric Motors

With regard to bearing maintenance of electric motors, personal recommendations are as follows:

1: In addition to the quality of the factory's own reliability, the maintenance of their own must be in the bearing dismantling process, their own inspection of the damaged parts, ball, roller, groove, cage, outer ring, inner ring wear;

If the inner and outer rings wear out, do not forget to spray the corresponding motor shaft and outer end cover;

2: As far as possible, use special disassembly tools for maintenance. The heating temperature should be controlled properly so as not to damage the bearings during installation.

3: As the upstairs heroes say, refueling is very important, according to the manual requirements, periodic fueling, choose the right oil is not free to change the number of lubricants, to avoid the agglomeration of the lubricant, it is best to refuel when the equipment is rotating , Or use hand-driven equipment to refuel, to ensure that the oil evenly added;

The more oil is not added, the better;

4: If the motor of the inverter is used, if there are burned articles in the inner ring of the bearing, it is recommended that the rear bearing be replaced with an insulating bearing. If it still has no effect, it is recommended to increase the DU/DT filter;

5: It is very important to ensure the concentricity of the connection with the mechanical equipment. Do a good job of calibration of the installation to avoid damage to the bearing due to external forces.
