Are the front and rear end caps of the motor the same as the bearing clearance?
2022/05/09
The motor generally has a fixed bearing at one end and a floating at the other end. The front end is a fixed end, the rear end is a floating end, and the spring is a wave spring, which is mainly used to preload the bearing to ensure the correct installation of the bearing and improve the service life. The outer ring of the bearing is generally a clearance fit with the inner hole of the end cover. In order to make the floating end of the rear end easier to move, the rear end gap is larger.
The front end of the motor, also called the working end, generally uses an interference fit. And the fan end uses clearance.
