[0002] A brake wheel is a mechanical component used for braking or decelerating, and is usually used in cooperation with a brake or a braking system. Press-fitting the brake wheel onto the motor shaft can achieve the braking function, that is, the motor shaft can be used as a part of the brake, and the rotation of the motor can be slowed down or stopped by the frictional force between the brake wheel and the motor shaft.

[0003] For this, it is necessary to press-fit the brake wheel onto the motor. The existing assembly method is to manually place the brake wheel on the workbench and use a hammer and a die to press-fit the brake wheel onto the motor. The entire process is to manually install the parts into the hub, resulting in low efficiency.
