Optimal Design and Research on the Structure of Tripod Constant Velocity Universal Joint

Abstract

In order to reduce the problems of wear between the internal structures of the universal joints and short service life, a new track contact structure was designed based on the original type of universal joint structure, and a mechanical model of the structure was established. In the ANSYS Workbench, the material properties, contact pair settings, universal joint force and other parameters are analyzed, the contact stress changes between the original structure and the optimized structure are studied, and the torsional fatigue life experiment is carried out in conjunction with the experimental workbench. The results show that the optimized new structure can effectively reduce wear and increase durability in the service process, thus extending its service life.
