【Abstract】 In order to study the influence of output type on the bearing capacity of star wheel reducer and find out the effective ways and methods to improve the bearing capacity of star wheel reducer, the structure and working principle of two output types of star wheel transmission gear trains were analyzed, and the calculation formulas of their transmission ratio, gear tooth meshing transmission coincidence degree and tooth profile interference inspection were derived.Three-dimensional models of two output types of planetary gear trains were established by SolidWorks. Based on ABAQUS finite element software, the numerical simulation and comparative analysis of load response characteristics of two output types of planetary gear trains were carried out. The results show that the two types of output planetary gear trains have multi-tooth contact elastic meshing transmission characteristics.Under the same load, when planetary gear output type is adopted for star gear reducer, its carrying capacity is higher than that of internal gear output type, and its meshing effect of gear teeth is better than that of internal gear output type.更多还原
