Arranged magnetic steel supporting device for rotor of permanent magnet motor

Abstract

The present invention discloses an arranged magnetic steel supporting device for the rotor of a permanent magnet motor. The device comprises a positioning support, rolling shafts and a brake pin. The positioning support comprises a base and two opposite bearers fixedly arranged at the two ends of the base. Along the top edge of each bearer, the bearer is provided with an inverted trapezoidal groove configured not to pass through the bottom edge of the bearer. The sidewall of the inverted trapezoidal groove is symmetrically provided with two arc-shaped grooves and rolling shafts are arranged in the arc-shaped grooves. The sidewall of each bearer is provided with a positioning groove and a limiting plate is fixed on the sidewall of the bearer. Each rolling shaft comprises a rotating shaft and an aluminum sleeve sleeved onto the outer surface of the sidewall of the rotating shaft. Bearings are arranged at the two ends of each rotating shaft. One end of each rotating shaft is connected with the limiting plate, and the other end of the rotating shaft is fixedly connected with a limiting circular disc. The limiting circular disc is fixed onto the sidewalls of the bearers through the brake pin. The device is simple in structure and strong in practicality. The problem in the prior art that no special device used for supporting the rotor of an existing permanent magnet motor is available during the production process of the permanent magnet motor can be solved. Meanwhile, the labor intensity of the motor production is greatly relieved, and the production safety is improved.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet motor production, and relates to a magnetic steel supporting device for a rotor of a permanent magnet motor. Background technique [0002] In recent years, with the increasing emphasis on the environment, the country's emphasis on new energy has become more and more important, and there are more and more new energy vehicles on the market. Therefore, the permanent magnet motor, the motor of new energy vehicles, is becoming more and more important to improve production efficiency and reduce the labor intensity of production employees in the production process. It is an important guarantee to increase the production output of permanent magnet motors. [0003] Therefore, in the production process of the permanent magnet motor, in the process of manufacturing the rotor of the permanent magnet motor, a tool with a simple structure and easy to use is needed. Contents of the invention [0004...
