Abstract

The invention relates to the technical field of motors, in particular to a motor shaft. The motor shaft comprises a shaft body, and is characterized in that the shaft body comprises a first half shaft and a second half shaft, wherein external threads are formed at the rear end of the first haft shaft; internal threads corresponding to the external threads are formed at the front end of the second half shaft; the first half shaft is connected with the second half shaft through the internal and external threads; knurls and ceramic membranes are arranged on peripheral surfaces of both the first half shaft and the second half shaft. The motor shaft is convenient for motor assembly and can improve the assembly efficiency.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor shaft. Background technique [0002] The motor is used to realize the conversion device of electric energy and mechanical energy and mechanical energy and electric energy. It is the main driving component in the modern industrial system. The rotor of the existing permanent magnet motor is composed of the motor shaft, the magnetic tile and the rotor cap. During the assembly production process, the rotor cap and the magnetic tile need to be fixed with screws, keys or positioning pins, etc., and then the rotor cap is fixed on the motor shaft. The whole process is cumbersome and difficult to improve assembly efficiency. Contents of the invention [0003] In view of the above problems, the present invention provides a motor shaft that is convenient for motor assembly and can improve installation efficiency, and can improve the wear resistance of the motor shaft, so as to solv...
