Causes of heating and damage to motor bearings (4)
Special Factors Affecting Motor Bearing System Problems
(3) Bearing heating under high-speed and heavy-load conditions
For high-speed motors with large loads, bearings with relatively high accuracy should be selected to avoid problems due to insufficient bearing accuracy. If the size consistency of the rolling elements of the bearing is not good, when the motor is running under load, due to the inconsistent force on each rolling element, there will be problems of natural vibration and wear of the bearing. In this process, metal chips may fall off and affect the operation of the bearing. Aggravate the occurrence and damage of bearings.
Especially for high-speed motors, due to the structure of the motor itself, the rotation of the shaft may be relatively small, and the possibility of deflection of the shaft during operation is high. Therefore, for high-speed motors, the material of the shaft is often required. Adjustment.
(4) The shrink-fit process of large motor bearings is not suitable
For small motors, the bearings use more cold pressing processes, while for large motors and high-voltage motors, more bearing heating processes are used. There are two heating methods, one is oil heating, and the other is induction heating. If the temperature control is not Well, when the temperature is too high, the bearing performance will fail, and after the motor runs for a period of time, there will be noise and heat problems.
