Abstract
The utility model belongs to the technical field of massage chairs, and particularly relates to a machine core overload protection device used for a massager. The machine core overload protection device used for the massager comprises a traveling driven big gear wheel and a traveling meshing pinion, wherein the traveling driven big gear wheel is sleeved on a protruding shaft of the traveling meshing pinion, and then a belleville spring is also sleeved on the protruding shaft. The traveling driven big gear wheel is squeezed by the belleville spring, and thereby radial grooves arranged on the lower end face of the traveling driven big gear wheel are matched with radial protruding half-cylinders arranged on the upper end face of the traveling meshing pinion. And finally, axially limiting the belleville spring and the traveling driven big gear wheel is achieved through an axial elastic check ring. Under the overload condition, the traveling meshing pinion and the traveling driven big gear wheel on an overload clutch device are in a coaxial departure connection, and a machine core traveling transmission device of the massager is enabled to drive the traveling driven big gear wheel on the overload clutch device to idle, and thereby the protection effect on a rack and a machine core of the massager is achieved, and the overload protection effect and the protection mechanism are improved.
