Motor for massage equipment or rocking chair

Abstract

The invention belongs to the field of motors, and particularly relates to a motor for massage equipment or a rocking chair. The motor for massage equipment or a rocking chair comprises a seat body for mounting a motor shaft and the motor shaft, and is characterized in that the seat body is provided with a shaft hole for mounting the motor, one end of the shaft hole is provided with a first bearing mounting cavity, the other end of the shaft hole is provided with a second bearing mounting cavity, the motor shaft is mounted in the shaft hole, a first bearing is fixed in the first bearing mounting cavity, a second bearing is fixed in the second bearing mounting cavity, and an elastic component is arranged between the side surface of the second mounting cavity and the second bearing. According to the invention, the assembly difficulty is reduced, and the problem of difficult installation is improved.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a motor for massage equipment or a rocking chair. Background technique [0002] In such a motor having a reduction mechanism, a small worm gear mechanism capable of obtaining a large reduction ratio is generally used as the reduction mechanism. [0003] Japanese Laid-open Document: JP 2006-31655 A, in the electric motor with reduction mechanism disclosed in this document, the rotating shaft is inserted into the bearing, and the middle part is supported by the bearing only in the radial direction. Therefore, when the shaft oscillates on the rotating shaft due to the reaction force between the worm and the worm wheel, the rotating shaft may move in the axial direction due to the wobbling of the shaft, resulting in abnormal noise or vibration. [0004] Therefore, the Japanese published document: JP2009-195028, the electric motor with the deceleration mechanism disclosed in this document is sh...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the present invention improves the motor used for massage equipment or rocking chairs, changes the installation position of the elastic part, and arranges the elastic part in the installation cavity of the second bearing on the rotor side, so that the When installing the first bearing, only the amount of adhesive needs to be considered to ensure the reliability of the connection between the first bearing and the seat body, which reduces the difficulty of assembly and improves the problem of difficult installation
