Abstract

PURPOSE: A brake gear in which a brake force increases smoothly and the operation of a large impact force onto a controlled shaft is prevented, even if a sharp and large shifting force operates in the axial direction onto a brake shoe.
CONSTITUTION: When the revolution speed of a motor shaft 2A increases and reaches a projected dangerous revolution speed, centrifugal pieces 11A-11C spring out against ring springs 11A and 11B, and contact the inner peripheral surface of the cylinder part 18A of a brake shoe 18. Accordingly, the brake shoe 18 is pulled by the centrifugal piece and revolved, and shifted in the axial direction by the action of a screw part 18C. When the brake shoe 18 shifts, and a brake wheel 8 is interposed between the brake shoe 18 and a brake disc 15, a frictional force is generated on an interposition surface, and brake is applied onto the motor shaft 2A. As a flush spring 17 is received at the back of the disc 15, the disc 15 retreats elastically, compressing the flush spring 17, and a brake torque is mitigated
