| Summary: | ObjectiveThe cycloidal pin gear reducer is popularized and applied for its high transmission ratio and compact structure. The transmission accuracy and smoothness of the cycloidal pin gear reducer is poor due to the high contact stress and low meshing stiffness between the cycloidal and pin gear. For the sake of further improving the load-bearing performance of the reducer, the analysis method was conducted to research the effect of structural parameters on the meshing stiffness by means of calculation and simulation.MethodsIn order to optimize its load-bearing performance, a mathematical analysis model of contact stress and meshing stiffness was proposed regarding the important structural parameters of cycloidal pin gear, as the design variables such as needle tooth distribution circle radius, eccentricity, and pin tooth radius; the VB.NET software was applied to calculate and analyze the influence of structural parameters of the cycloidal pin gear on the meshing stiffness, contact stress, meshing force, and torsional stiffness of the cycloidal pin gears pair.ResultsThe results of calculation and simulation indicate that the meshing stiffness and torsional stiffness of cycloidal pin gear increase with the increase of the radius of the distribution circle and eccentricity and the decrease of the radius of the teeth. The research provides foundation for the design and optimization of the structure of cycloidal pin gear reducers. |
