Causes of heating and damage to motor bearings (4)
Special Factors Affecting Motor Bearing System Problems
(5) Deformation and cracks in end cover bearing chamber and bearing sleeve
This problem mostly occurs in the casting parts of large motors. Since the end cover is a typical plate-shaped part, large deformation may occur during the casting process and the processing process. Some motors have cracks in the bearing chamber during the storage process. It leads to noise or even fatal sweep quality problems during the operation of the motor.
For the bearing system problem, there may be other uncertain factors. The reasonable matching of bearing parameters and motor parameters is the most effective way to improve. For this aspect, some bearing manufacturers are already doing it, especially for brands with relatively high quality. Some good bearing manufacturers have also matured through the matching modeling rules of motor load and operating characteristics. These relatively fine improvements will effectively reduce the problems of the motor bearing system.
