The utility model discloses a
massage machine core driving mechanism with high stability and capable of reducing loss and
noise, which comprises a
massage wheel
assembly, a beating driver, a beating transmission shaft, a beating eccentric wheel, a swing arm and a limiting
assembly, an eccentric hole is formed in the swing arm, and a limiting hole is formed in the limiting
assembly; the beating eccentric wheel is arranged on the beating transmission shaft and assembled with the eccentric hole in the swing arm, and the beating transmission shaft penetrates through the limiting hole of the limiting assembly, so that when the beating driver drives the beating transmission shaft to rotate, the beating transmission shaft drives the swing arm and the
massage wheel assembly through the beating eccentric wheel; and the massage wheel assembly is enabled to perform beating
massage action in a movement range limited by the limiting hole of the limiting assembly. Therefore, the radial action range of the beating transmission shaft can be controlled through the limiting hole of the limiting assembly, then the beating
massage action range of the massage wheel assembly is controlled, the massage stability, safety and massage effect are improved, and beating massage damage to a user is avoided.
