Measures to prevent noise from bearing cage of coal mining machine
The sound source of the raceway is caused by the natural vibration of the ring after being loaded. Because of the elastic contact between the ring and the rolling element, a nonlinear vibration system is formed. When the lubrication or machining accuracy is not high, the natural vibration related to this elastic characteristic will be excited, and it will become noise when it is transmitted to the air.
