A low-inertia field-free safety brake suitable for high-speed precision transmission

Abstract

The application relates to the technical field of brakes, and particularly discloses a low-inertia field-free safety brake suitable for high-speed precise transmission, which comprises a shell, a follower disc arranged in the shell, a bearing seat, a magnetic yoke assembly and a brake disc. The bearing seat is arranged in the shell in an axial sliding mode, the circumferential inner wall of the shell is provided with a ring protrusion, the magnetic yoke assembly is fixedly sleeved on the bearing seat, the brake disc is arranged in the shell in an axial sliding mode and located between the magnetic yoke assembly and the follower disc, one end of the brake disc close to the magnetic yoke assembly is provided with an armature, and a plurality of second compression springs distributed in a circumferential array are arranged between the armature and the ring protrusion. The application realizes manual presetting and elastic following compensation of the brake gap after the brake disc is worn, ensures that the brake can still maintain stable electromagnetic suction force and brake response speed after long-term use, avoids brake failure caused by excessive wear of the brake disc, and improves the use safety of the brake.
