High-efficiency AC permanent magnet synchronous traction machine noise-reduction brake

Abstract

The invention discloses a high-efficiency AC permanent magnet synchronous traction machine noise-reduction brake. The brake comprises a traction machine spindle, a traction machine end cover, a brake disk and a brake mechanism, wherein the traction machine end cover, the brake disk and the brake mechanism are arranged on the periphery of the traction machine spindle in an encircling mode and are sequentially arranged along the traction machine spindle in the axial direction. The brake is characterized in that the end of the traction machine spindle is fixedly connected with a connecting plate; the connecting plate is fixedly connected with the brake disk through a plurality of bolts; each bolt is sleeved with a spring; one end of each spring abuts against the brake disk, and the other end of each spring abuts against the connecting plate; the springs have tensile force for pushing the brake disk to get away from the traction machine end cover; and the traction machine end cover and the brake mechanism are connected together through pillars.

Description

technical field [0001] The invention relates to a traction machine braking device, in particular to a high-efficiency AC permanent magnet synchronous traction machine noise reduction brake. Background technique [0002] After the braking of the traction machine is completed, the brake disc will be separated from the end cover of the traction machine. At this time, if the position of the brake disc is not restored along its own circumferential direction, a part of the brake disc will still exist in the traction machine. The friction phenomenon of the end cover of the traction machine will cause friction noise, and at the same time, the friction will easily damage the end cover of the traction machine and the brake disc. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a high-efficiency AC permanent magnet synchronous traction machine noise reduction brake. [0004] In order to achieve the above purpose, the technical...
