Technical Field

[0001] This utility model relates to the field of electric motor technology, and in particular to a kneading motor for a massage chair. Background Technology

[0002] In the field of massage equipment, especially in the design of kneading motors for massage chairs, in order to achieve the output characteristics of low speed and high torque, a transmission structure with worm gear and worm wheel is usually adopted. The worm sleeve is fixed to the outside of the motor shaft by welding. The meshing characteristics of worm gear and worm wheel are used to achieve the function of speed reduction and torque increase, thereby meeting the demand of massage kneading action for low speed and high torque.

[0003] However, the existing method of welding and fixing the worm sleeve to the outside of the motor shaft has problems. Because the worm sleeve is prone to wear due to long-term high-torque rotation, when the worm sleeve is damaged and needs to be replaced, the welded part must be cut and separated, which is time-consuming.

[0004] Therefore, how to optimize the connection between the worm gear sleeve and the rotating shaft to achieve quick assembly and disassembly has become a pressing technical problem to be solved in the design of massage chair kneading motors. Utility Model Content

[0005] The purpose of this invention is to provide a kneading motor for a massage chair to solve the problems mentioned in the background art.

[0008] A transmission assembly includes a worm sleeve sleeved on the outside of an output shaft. A connecting part for connecting the worm sleeve and the output shaft is inserted through the outside of the worm sleeve. A locking part is provided on the side of the output shaft away from the kneading motor body. A reinforcing part for assisting the connection part is provided at the insertion point of the output shaft and the worm sleeve.

[0009] Preferably, the connecting part includes a connecting bolt, the end of which is sequentially inserted and connected to the outside of the worm sleeve and the outside of the output shaft.

[0013] Preferably, the springback element includes:

[0014] A gasket, wherein the gasket is fitted onto the outside of the positioning bolt;

[0015] A compression spring is sleeved on the outside of the positioning bolt and located on the side of the washer near the worm sleeve.

[0016] Preferably, a movable groove is provided at the intersection of the output shaft and the positioning bolt, and the gasket and compression spring are both disposed in the inner cavity of the movable groove.

[0017] Preferably, a positioning groove is provided on the outer side of the connecting bolt, and the positioning groove is used for the insertion of the positioning bolt.
