Description

Technical Field

[0001] The utility model relates to the field of brakes, in particular to an electromagnetic brake with a reset leaf spring placed in the brake body. Background Art

[0002] An electromagnetic brake is a connector that transmits the torque on the active side to the passive side, and can be freely combined, disengaged or braked as needed. It has the advantages of compact structure, simple operation, sensitive response, long service life, reliable use, and easy realization of remote control.

[0003] The existing electromagnetic brakes generally assemble an armature, a wave washer and an additional shaft sleeve together to form a brake pad assembly, which has the following problems:

[0004] 1. When disassembling and assembling the brake pads, the wave washer is easily scratched, resulting in brake failure;

[0005] 2. The dynamic balance of the brake pad assembly is damaged due to assembly errors, resulting in resonance during rotation;

[0006] 3. Since the combination of the armature, the wave washer and the shaft sleeve rotates with the shaft, there is a certain probability of abnormal noise and vibration during high-speed rotation, affecting the use of the entire system;

[0007] 4. Due to the mutual influence and addition of problems 2 and 3, greater vibration and abnormal noise will be caused.

[0008] Therefore, there is an urgent need for an electromagnetic brake with a reset leaf spring placed in the brake body to solve the above problems. Summary of the Utility Model

[0009] The purpose of the utility model is to provide an electromagnetic brake with a reset leaf spring placed in the brake body to solve the problems existing in the above-mentioned prior art.

[0010] To achieve the above purpose, the utility model provides the following scheme:

[0011] The utility model provides an electromagnetic brake with a reset leaf spring placed in the brake body, including a brake body, an armature and a wave washer, characterized in that: the wave washer is fixed to the bottom of the brake body, and the armature is independently arranged on the top of the brake body and is rigidly assembled with a rotating shaft.

[0012] Preferably, the wave washer is fixedly connected to the brake body by screws or rivets.

[0013] Preferably, the wave washer is fixed to the outside of the mounting plate.

[0014] Preferably, the wave washer is fixed to the inside of the outer cover.

[0015] The utility model has achieved the following beneficial technical effects compared with the prior art:

[0016] An electromagnetic brake with a reset leaf spring placed in the brake body provided by the utility model comprises a brake body, an armature and a wave washer. The wave washer is fixed at the bottom of the brake body. The armature is independently arranged at the top of the brake body and is rigidly assembled with a rotating shaft. By installing the wave washer at the bottom of the brake body and producing the armature with a single material, complete dynamic balance can be achieved, and it is rigidly assembled on the rotating shaft, completely eliminating the abnormal noise and vibration caused by the armature plate, and greatly reducing the probability of damaging the wave washer during disassembly and assembly. Thus, the problems that the wave washer was easily damaged during disassembly and assembly, difficult to adjust dynamic balance, prone to generate abnormal noise and cause system vibration are cured, making the overall performance of the brake more stable and capable of coping with more application scenarios.
