Combined tooth surface oscillating tooth transmission meshing pair and generating method thereof

Abstract

The invention provides a combined tooth surface oscillating tooth transmission meshing pair and a generating method thereof. The combined tooth surface oscillating tooth transmission meshing pair includes a combined tooth surface raceway, an oscillating tooth, a combined tooth surface transmission wheel and the like. On the basis of a traditional transmission configuration, the large size oscillating tooth is selected to meet the undercutting condition. On the basis, the oscillating tooth section is discretized into three or four different sections, each section separately sweeps along a meshing curve to obtain a corresponding meshing tooth surface, or spins around the edge line to obtain the corresponding tooth surface, then the three or four specific tooth surfaces are pieced together into a whole, that is, the combined tooth surface oscillating tooth raceway is formed, and then the corresponding oscillating tooth is matched to form the combined tooth surface oscillating tooth transmission meshing pair.

Description

technical field [0001] The invention relates to the technical field of movable tooth transmission, in particular to a combined tooth surface movable tooth transmission meshing pair and a generating method thereof. Background technique [0002] With the development of movable tooth transmission technology, various movable tooth transmission configurations emerge in endlessly, such as push rod movable tooth transmission, roller (steel ball) movable tooth transmission, swing movable tooth transmission, sleeve movable tooth transmission and Planar steel ball transmission, etc.; no matter what form of movable tooth transmission technology, its core and essence is the movement of the movable tooth along its meshing curve, and the space track surface obtained by the movable tooth moving along the meshing curve is the actual movable tooth meshing tooth In the traditional movable tooth design, the actual meshing tooth surface is continuous and avoids undercutting. For example, the p...

Problems solved by technology

However, in the case of following the traditional design methods and rules, the power density of the designed reducer is not ideal. Generally speaking, it is large in size, relatively small in transmission ratio, and insufficient in space utilization.

All the existing research and optimization are based on the condition that the meshing pair is not undercut. The general optimization is to optimize the parameters and modify the tooth shape, which has great limitations and cannot be used for the reducer. to significantly improve performance
