Problems solved by technology

[0002] The shaft sleeve of the rotor in the prior art is fixed to the motor housing by injection molding or interference fit, and the working conditions of the fan electronics are generally relatively harsh. After long-term use, the shaft sleeve and the motor housing are prone to loosening , and then the shaft sleeve will rotate with the shaft, which will bring greater shaking and noise, which will affect the service life of the fan

Description

Technical field: [0001] The invention relates to a shaft sleeve for a motor rotor. Background technique: [0002] The shaft sleeve of the rotor in the prior art is fixed to the motor housing by injection molding or interference fit, and the working conditions of the fan electronics are generally relatively harsh. After long-term use, the shaft sleeve and the motor housing are prone to loosening , and then the shaft sleeve will rotate with the shaft, causing greater shaking and noise, which affects the service life of the fan. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide a shaft sleeve for motor rotor with simple structure and ensuring the connection reliability between the shaft sleeve and the motor housing. [0004] The purpose of the present invention is achieved by the following technical solutions: a shaft sleeve for a motor rotor, comprising [0005] A shaft sleeve body, the center of which is pro...
