A damping ring assembly and an electric motor having the same

Abstract

The invention belongs to the technical field of motors, and discloses a damping ring assembly and a motor having the same. The damping ring assembly comprises an upper rubber ring and a lower rubber ring, wherein the upper rubber ring and the lower rubber ring each comprises a central hole, an upper surface, a lower surface and an outer surface; the central holes of the upper rubber ring and the lower rubber ring are coaxially arranged and have the same size, and the outer surfaces of the upper rubber ring and the lower rubber ring are respectively provided with corresponding angle matching marks; the lower surface of the upper rubber ring and the upper surface of the lower rubber ring are respectively provided with uniformly distributed protrusions and grooves which can cooperate with each other. The damping ring assembly further comprises one or more rubber rings, and the rubber rings are provided with mounting holes matched with the protrusions. By use of the damping ring assembly,the mounting angle can be arbitrarily changed without reducing the production efficiency; the number of rubber rings is adjusted, the axial length can be arbitrarily adjusted, the production cost is reduced and the production efficiency is improved; and the upper and lower ruber rings of different hardness can be used to cooperate to enhance the damping effect.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a shock absorbing ring assembly and a motor with the same. Background technique [0002] When the motor is working, it needs to rotate continuously, and the rotation will cause vibration and noise. In order to reduce noise and absorb vibration, a shock absorber ring is usually set inside the motor. [0003] Existing motors are generally equipped with shock absorbing rings, which are fixed on the motor through tight fit. Its main function is to prevent the vibration from being transmitted to the load when the motor is running, causing noise problems. At the same time, it can also ensure the installation size of the motor. Enhance the versatility of the same motor. [0004] Usually, the shape of the shock absorbing ring is mainly determined by the load. If the shape of the load changes slightly, such as the installation direction changes, the installation axial length changes, etc...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned technical problems in the prior art, one of the purposes of the present invention is to design a shock absorbing ring assembly, which can solve the problem of the generality of the existing shock absorbing ring under the condition that the load does not change substantially. problem, and the existing damping ring only adopts a tight fit fixing method to ensure reliable fixation with the motor, which causes the problem that the damping effect is not optimal
