Abstract

The invention discloses an anti-shock permanent magnet brake, which comprises a stator and a rotor. The stator is composed of a stator inner shell, a magnetic isolation washer, an armature, a stator shell, a permanent magnet, and a pressure plate; the rotor is composed of a friction plate, a plate Composed of springs, rivets, and rotor bases; the invention uses permanent magnet magnetic steel to provide the positive pressure of the friction pair of the brake, which has the characteristics of strong impact resistance and high torque density; it can effectively reduce the electromagnetic volume of the brake and increase the torque density of the brake. Realize the miniaturized design and production of the brake; at the same time, under the mechanical environment, the magnetic force of the magnetic steel is more stable and reliable than the spring force, and the spring self-vibration problem will not occur during the vibration and shock process, ensuring the locking of the brake in the vibration and shock environment reliability.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to an anti-shock permanent magnet brake. Background technique [0002] With the development of science and technology, the brake is used as a zero-position locking device. The traditional spring brake has poor impact resistance and low torque density, which cannot meet the requirements of miniaturization and high impact. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the invention provides an anti-shock permanent magnet brake, which solves the existing problems of poor anti-shock ability, low moment density, and inability to meet the requirements of miniaturization and high impact. [0005] (2) Technical solution [0006] In order to achieve the above object, the present invention provides the following technical solutions: an anti-shock permanent magnet brake, including a stator and a rotor, the stator is co...
