Problems solved by technology

The problem arising from the above situation is that the power density of the traditional cycloidal steel ball movable gear reducer is not high. Generally speaking, it is large in size, relatively small in transmission ratio, insufficient in space utilization, and lack of market competitiveness.

Abstract

The present invention provides a center-symmetric double-stage nested undercut cycloid movable gear reducer, which includes an outer drive wheel, a first cross roller bearing, an inner drive wheel, a tapered roller bearing, an input shaft and the like. The transmission mechanism of the present invention is obtained by the centrally symmetrical arrangement of two inner and outer nested double-stage differential undercut cycloid movable tooth transmission units; the undercut cycloid raceway is divided into an undercut hypocycloid raceway and a root According to the axial arrangement, this reducer has four types of configurations. For each category, it is divided into double-stage undercut hypocycloid raceway and double-stage undercut outer cycloid raceway. Cycloidal raceway, the first level is undercut hypocycloid raceway, the second level is undercut epicycloid raceway and the first level is undercut epicycloid raceway, and the second level is undercut hypocycloid raceway. A total of sixteen configurations; flexible configurations, a wide range of transmission ratios, and mechanical dynamic balance characteristics 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-symmetric double-stage nested 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. With t...
