What Should I Do If The Bearing Of The DC Traction Motor Is Damaged?

First of all, the grease in the bearing raceway is in a state of strong agitation for a long time. The torque of the bearing is large and the temperature is high, resulting in unbalance. After further increase of temperature, a series of vicious cycles will be caused, resulting in the inside and outside of the bearing. The circle and the rolling element are stuck and cannot work.

Secondly, common failure symptoms of bearings include loose rivet of the cage, breakage or partial eccentric wear of the ribs, rolling and raceway peeling, burn marks, strains, cracks, honing or radial clearance, and the inner ring is loose or bitten. , shaft current erosion and grease deterioration, bearing  tank loose deformation. Therefore, vibration and noise are often caused to increase, resulting in pinion collision wear, winding insulation damage, joint breakage, poor commutation, grounding or ring fire, and even a rotor accident that is difficult to rotate and crack the shaft.

Finally, the bearing is too loose or too tight with the shaft. When it is too loose, it is sleeved on the bearing, and when it is too tight, the shaft is reworked to the standard size.
