Abstract
Disclosed in the present invention is a transmission mechanism, comprising an outer wheel, an inner wheel, an eccentric shaft, a first flange body, a rotating shaft and a planetary gear device. The inner wheel is provided in the outer wheel and is engaged with the outer wheel. The eccentric shaft can rotate around a central axis; an eccentric portion, eccentric shaft outer teeth and a first support portion are provided on the periphery of the eccentric shaft; and the inner wheel is provided around the eccentric portion. The first flange body and the inner wheel are provided side by side, and the first flange body is provided around the first support portion. The rotating shaft has rotating shaft external teeth. The planetary gear device is supported by the first flange body, and a first row of planetary teeth engaged with the rotating shaft outer teeth and a second row of planetary teeth engaged with the eccentric shaft outer teeth are provided at the periphery of the planetary gear device. The transmission mechanism can provide a wide range of speed ratios and reduce production costs.
