Force analysis for pure rolling movable teeth transmission

摘要

Based on the principle of sliding and rolling substitution, combined movable tooth design, approaches were presented to eliminate the slip phenomenon, ensure the pure rolling contact of meshing pairs and realize pure rolling movable teeth transmission. According to the coordinate condition of elastic deformation, force analysis was conducted on the meshing pairs of rolling movable teeth transmission. The mathematical model of meshing force was established to analyze the meshing force between shock wave cam, central wheel and movable tooth, the engagement position of maximum contact force was determined, which can provide reference for the further strength check and structure optimization design.
