Ultra-thin de-excitation brake for precision equipment

Abstract

The application relates to the technical field of brakes, and discloses an ultra-thin non-field excitation brake for precision equipment, which comprises a sleeve shell and a sealing plate, the end of the sleeve shell away from the sealing plate is inwardly folded to form an L-shaped air guide ring plate, the circumferential inner wall of the sleeve shell is provided with a limiting ring plate arranged in an integrated mode, the side of the limiting ring plate close to the air guide ring plate is provided with a wind blocking convex ring, a plurality of limiting studs are arranged between the limiting ring plate and the sealing plate, the side wall of the sealing plate is provided with a plurality of air outlet holes, a horizontal moving piece is slidably arranged between the limiting ring plate and the sealing plate through the limiting studs, a plurality of compression springs are arranged between the sealing plate and the horizontal moving piece, and the compression springs are in sleeve connection with the adjacent limiting studs. The application realizes compact and thin design of the brake, realizes power-off self-locking and two-stage redundant braking of the non-field excitation brake, and realizes passive heat dissipation design of forcibly air cooling of the fan blades by using the rotating power of the equipment.
