Abstract

The invention discloses a reduction gear with group drive of an involute gear and a cycloid gear. A double reduction mechanism with group drive of the planetary involute gear and the cycloid gear is arranged in a closed cavity; a planetary involute gear drive reduction mechanism is formed in the mode that a motor rotates to drive a sun gear to rotate and then drive an annular gear and a planetary gear to rotate; a cycloid gear group drive reduction mechanism comprises an eccentric shaft, a cycloid gear ring and a cycloid gear, the gear tooth difference of the cycloid gear ring and the cycloid gear is one gear tooth, an internal gear tooth and an external gear tooth are meshed to form an internal gearing reduction mechanism, wherein the gear tooth difference is one gear tooth.

Description

technical field [0001] The invention relates to a reduction device in mechanical transmission, in particular to a reduction device for combined transmission of an involute gear and a cycloid gear. Background technique [0002] In the involute planetary gear transmission, several planetary gears are usually used to transmit loads at the same time, split the power and reasonably use internal meshing, so it has a series of advantages: such as compact structure, small size, light weight, transmission ratio range Large, the tooth shape is formed by a curve, so it is easy to manufacture. [0003] Compared with the general gear transmission, the cycloidal pin wheel planetary gear has the following characteristics: the hypocycloid and the epicycloid of a pair of tooth profiles mesh during transmission, so the contact stress is small and the wear is uniform; the coincidence of the tooth profiles is large, It is conducive to the improvement of bending strength; the structure is compa...
