【Abstract】 Based on the theory of the nutation transmission with conical movable teeth,the 3D model of the whole transmission device is established by Pro / E for a given set of parameters. The force analysis model of the center disk is established using the theory of contact mechanics,and the conical movable teeth and the center disk force state in the transmission are analyzed. The analysis of the center disk tooth surface contact strength is conducted using Hertz elastic contact theory and finite element method. The results show the correctness of the force analysis model established,and the stress distribution of the center disk is obtained. The corresponding improvement measures are proposed,which provides a theoretical basis for follow-up product design.更多还原
