Abstract

The invention discloses a deceleration device for combined transmission of involute gear and cycloid gear. In a closed cavity, a two-stage deceleration mechanism for combined transmission of planetary involute gear and cycloid gear is provided; the planetary The involute gear transmission deceleration mechanism is formed by the rotation of the motor to drive the sun gear to rotate, and then drives the inner ring gear and the planetary gear to rotate; the cycloid gear transmission deceleration mechanism is composed of an eccentric shaft, a cycloid ring gear and a cycloid wheel Composition, the cycloid ring gear and the cycloid wheel have a tooth difference, and when the internal and external teeth are meshed, an internal meshing reduction mechanism with a tooth difference of one tooth is formed.

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...
