Abstract

The invention provides a motor structure. The motor structure comprises a motor shell, a motor body, a bearing fixing seat and a bearing, a boss is arranged at the bottom of the motor shell in a protruding mode, and a base cavity is formed in the boss. The bearing fixing seat is arranged in the base cavity; the bearing is arranged in the bearing fixing seat; the motor body is arranged in the motorshell, and a main shaft of the motor body extends into a bearing hole of the bearing; and the main shaft can rotate in the bearing hole. By adopting the scheme provided by the invention, the retention force of the self-aligning bearing can be effectively reduced, and the bearing is prevented from being locked, so that the friction force between the main shaft and the bearing is reduced, the noiseis reduced, the service life of the bearing can be effectively prolonged, the self-aligning force of the bearing is increased and the probability that the main shaft is locked is reduced.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a motor structure. Background technique [0002] At present, in the motor structure, there is a failure mode that the bearing fixing seat cannot be fixed, causing it to rotate, and then the self-aligning bearing loses its self-aligning effect. This failure mode is common, especially in the generator and motor industries. [0003] The self-aligning bearing is generally connected to the main shaft, and the bearing fixing seat fixes the self-aligning bearing, so that the self-aligning bearing plays the role of self-aligning; when the main shaft rotates, a torque is applied to the bearing, and the bearing will transmit this torque to the bearing fixing seat In general, when the torque reaches a certain value, or under high temperature conditions, the bearing fixing seat will creep, and the shape and size will change, causing the bearing fixing seat to loosen and drive the ...
