Abstract

Provided is a compact brake release device for an electromagnetic brake capable of releasing the brake with precision and with less force than a lever type release lever. The device comprises: a shaft that can be inserted into a threaded portion of a brake shoe assembly that is housed in a brake core; a base that receives the reactive force to tension in the shaft during brake release; a ball screw fastened to the shaft and a ball screw nut; a radial bearing that is press fit into the outer rim of the ball screw nut; a guide fastened to the outer rim of the radial bearing; a handle mounted on the ball screw in the axial direction; a thrust bearing that is fastened between the guide and the base and that receives the reactive force of the ball screw nut of the ball screw during release; a flange provided on the ball screw nut; an engaging hole provide concentrically in the circumferential direction of the flange; a mating portion provided on the ball screw nut; a release lever capable of being mounted in the mating portion; and a protruding portion that is provided at the distal end of the release lever and that is capable of being mounted in the engaging hole in the flange.
