AI Technical Summary
The existing rolling bearing bracket assembly is usually directly installed through the bearing when installing the air-drying motor, resulting in the relatively fixed position of the air-drying motor, which has limitations. When there are errors in the washing machine manufacturing process, the centering needs to be centered during the installation of the air-drying motor, but it is difficult to achieve.
A rolling bearing bracket assembly with a center-aligning function is designed, including a motor stator core, a motor rotor and a motor output shaft. By providing a structure such as the first and second bearing brackets, fixing mechanisms, spherical grooves and bushings, the angle adjustment of the motor rotor is realized.
This design increases the flexibility of the motor rotor, facilitates centering, and can adjust the angle of the motor rotor when errors occur in production processes, improving the practicality of the rolling bearing bracket assembly.
