Abstract

The invention relates to an elastic component for adjusting an axial clearance of a motor, which is padded at a tail end of a transmission shaft of the motor. One end surface of the elastic component is pressed against an inner wall of the motor, and the other end surface of the elastic component is pressed against shaft end gasket sleeved on the transmission shaft of the motor. Both end surfaces of the elastic component, which are pressed against the inner wall of the motor and the shaft end gasket respectively, are planes. Lateral surfaces connecting the two end surfaces on the elastic component are arc surfaces. The elastic component can compensate the clearance generated by assembly in the range of a certain force, and particularly realizes the adjustment of the axial clearance of the motor by matching the shaft end gasket. The elastic component has small size, realizes large compensation range, can realize zero-clearance assembly, and has simple structure and easy quantification production. Moreover, a reasonable section structure of the elastic component is utilized to make the change of the elasticity of the elastic component similar to linear change and make the axial movement change stably due to an axial force so as to reduce noise.

Description

technical field

[0001] The invention relates to an elastic part, in particular to an elastic part used for adjusting the axial gap of a motor in cooperation with a shaft end gasket. Background technique

[0002] At present, the adjustment of the axial clearance of the motor can be realized by two methods: inelastic control and elastic component control.

[0003] Inelastic control, such as Figure 4 As shown, the axial clearance of the motor is adjusted through shaft end gaskets of different thickness sizes. The disadvantage is that a certain number of shaft end gaskets with different thickness specifications are required, because the classification of thickness specifications directly determines the adjustment accuracy of the axial clearance. The assembly needs to cooperate with the pre-inspection of the axial clearance and then select the shaft end gaskets of different specifications; the number of parts is large, the precision is high, the assembly is complicated, and the ...
