The invention provides a center-symmetrical double-stage differential undercut cycloid movable gear reducer, which includes an input shaft, angular contact ball rollers, a first cage, a rear transmission wheel and the like. The transmission mechanism of the present invention is obtained by arranging two double-stage differential undercut cycloid movable tooth transmission units in a centrally symmetrical manner; the undercut cycloid raceway is divided into an undercut hypocycloid raceway and an undercut epicycloid raceway According to the axial arrangement, this reducer has four types of configurations. For each category, it is divided into double-stage undercut hypocycloid raceways, double-stage undercut epicycloid raceways, and double-stage undercut epicycloid raceways. The first level is an undercut hypocycloid raceway, the second level is an undercut epicycloid raceway and the first level is an undercut epicycloid raceway, and the second level is an undercut hypocycloid raceway. There are 16 configurations in total type; flexible configuration, wide transmission ratio range, and mechanical dynamic balance are the inherent attributes of the present invention. Relying on these attributes, the present invention has many advantages and strong applicability.
Description
technical field [0001] The invention relates to the technical field of movable tooth transmission, in particular to a center-symmetrical double-stage differential undercut cycloid movable tooth reducer. Background technique [0002] In the traditional involute gear transmission, in some special cases, the designed gear will appear undercut, although it does not affect the transmission accuracy of the gear, but the root of a single tooth becomes thinner due to the thickness of the undercut, and the bending resistance of the gear decreases , the degree of coincidence is reduced, which affects the stability of the transmission. Therefore, in the traditional design idea, the design of the involute gear is to avoid undercutting as much as possible. In another traditional transmission form—cycloidal pinwheel transmission technology, the actual tooth profile of the cycloidal wheel is strictly not allowed to undercut, because undercutting will cause its transmission to be distorted....
