| Abstract: The contact characteristics between cycloidal gear teeth and pinwheel teeth significantly impact the operational performance of cycloidal pinwheel mechanisms. Existing research methods primarily rely on theoretical calculations, lacking experimental methods for detecting dynamic contact properties. We propose a novel method for testing the dynamic contact characteristics of cycloidal pinwheel mechanisms. By combining Hertzian contact theory and contact strength theory, we establish a force and meshing stiffness model for the cycloidal and pinwheel gears, determining the maximum contact stress and variations in pinwheel gear force and meshing stiffness. Based on the principle of photoelasticity, we built a testing platform for the cycloidal pinwheel mechanism to assess its contact characteristics. This platform provides the stress distribution of the cycloidal pinwheel mechanism and allows us to deduce key parameters such as the number of meshing teeth and the meshing interval. This study provides an experimental method for investigating the contact characteristics of cycloidal pinwheel mechanisms. |
