Abstract

The invention provides a motor end cover, which comprises a main body and a bearing seat. The main body comprises a hollow cylindrical side wall and an annular top cover; the bearing seat comprises a hollow cylindrical outer layer body and a hollow cylindrical inner layer body; and the side wall, the top cover and the outer layer body are formed in an integrated stretching mode. the bearing seat of the motor end cover of the invention is separated into the outer layer body and the inner layer body, and compared with a past bearing seat which is formed in an integrated mode after stretching for multiple times and then finishing, realization of high coaxiality is more facilitated. In addition, as the number of stretching is reduced, anisotropy, cold-work hardening and stress influences of a plate are reduced, roundness of a main body inner circle of the motor end cover is improved. On the basis that coaxiality and roundness are enhanced to a certain degree, the vibration amplitude, the frequency and the noise of the motor during the operation process are restrained, an air gap between a stator and a rotor is reduced, the motor efficiency is improved, and the motor with the motor end cover can be actively and meaningfully applied to various industries.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor end cover and a production method thereof. Background technique [0002] For small motors used in household equipment such as air conditioner outdoor units, indoor units, air purifiers, high-power exhaust fans, and air curtain machines, a very important performance index is the coaxiality between the stator and rotor of the motor, because generally the The stator is fixed on the inner ring of the main body of the motor end cover, the rotor is fixed on the motor shaft, and the two ends of the motor shaft are connected to the motor end cover through the bearings fixed on the bearing seat, so this index mainly depends on the center position of the motor end cover The coaxiality between the inner ring of the bearing and the inner ring of the main body; in the existing technology, the motor end cover is produced by using a stamping die to process more than ten processes such as...
