For example, the other end of the brake ring 14 and the side cover 15 are connected by bolts.
当需要限制制动器13的轴向位置时，可在电机轴124上设置挡圈16，并在电机轴124的一端端部设置压盖19，使制动器13的一端压盖19，另一端顶抵挡圈16。例如，压盖19与电机轴124通过螺栓连接。When it is necessary to limit the axial position of the brake 13, a retaining ring 16 can be arranged on the motor shaft 124, and a gland 19 can be arranged at one end of the motor shaft 124, so that one end of the brake 13 presses the cover 19 and the other end abuts the retaining ring 16.
