Shockproof rotor

Abstract

The invention discloses a shockproof rotor. The shockproof rotor comprises a rotating shaft, a rotor body and permanent magnets; the rotating shaft is fixedly connected with the rotor body; the rotor body is provided with a plurality of permanent magnets accommodating grooves; the rotating shaft is provided with fixing disks located at two sides of the rotor body; the fixing disks are provided with a plurality of permanent magnet fixing clamping grooves; the permanent magnets are long-strip-shaped; two permanent magnets are provided with fixing portions which extend outwards and are arranged in the clamping grooves of the fixing disks and elongated portions which are embedded in the accommodating grooves of the rotor body; the interior of the middle of the rotor body is hollow; the hollow part of the rotor body is filled with flexible materials; the rotor body is fixedly connected with the rotating shaft through keyways; and a plurality of keyways are provided and are uniformly distributed along the circumference of the rotating shaft. According to the shockproof rotor of the invention, defects in the prior art can be eliminated, and the designed structure of the shockproof rotor is compact, and the permanent magnets are fixed firmly and do not tend to deviate, and the service lives of the permanent magnets are long; and the flexible materials in the rotor body and the rotor body are fixedly connected with the rotating shaft through the keyways, and therefore, the inertia force of the rotor body can be reduced.

Description

technical field [0001] The invention relates to the technical field of motor components, in particular to an anti-vibration rotor. Background technique [0002] The motor is a conversion device used to realize electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is a rotating part in the motor and is a consumable part. During the operation of the existing motor rotor, the permanent magnet is easily displaced or separated from the rotor body, which shortens the service life of the rotation. At the same time, it is difficult for the motor to work for a long time, which reduces the durability of the motor. Although the existing patent No. CN203278437U adopts some technical means to strengthen the fixing of the permanent magnet in the rotor body, it adopts some conventional reinforcement methods, and most of them use some connectors to strengthen the connection.

AI Technical Summary

Problems solved by technology

During the operation of the existing motor rotor, the permanent magnet is easy to shift or break away from the rotor body, which shortens the service life of the rotation, and at the same time, it is difficult for the motor to work for a long time, which reduces the durability of the motor

Although the existing patent No. CN203278437U adopts some technical means to strengthen the fixing of the permanent magnet in the rotor body, it adopts some conventional reinforcement methods, and most of them use some connectors to strengthen the connection. It is cumbersome, easy to grow and loose, and the overall effect is not ideal when used

In addition, when the rotor rotates at a certain speed, it will deform greatly and cause resonance. If such vibration is not reduced, it will affect the firmness of the permanent magnet installation.
