Load Characteristics Analysis of Cycloidal Pin Gear Considering Influence of Tooth Profile Error
In view of the lack of load analysis software considering tooth profile error,the analysis results were not in line with the actual engineering conditions,a load characteristic analysis method of cycloidal pin gear pair including cycloidal gear tooth profile error was proposed.The actual tooth profile of cycloidal gear with tooth profile error was accurately described by cubic non-uniform B-spline.The contact analysis model of cycloidal pin gear error tooth profile(error tooth contact analysis,E-TCA)was constructed and analyzed.The initial meshing position parameters and meshing clearance were obtained.On this basis,the load contact analysis model of cycloidal pin gear pair under the influence of tooth profile error was established.The torque balance and deformation coordination relationship between multi-body contacts of parts were determined.The real load characteristics were obtained by using the principle of minimum energy.The load characteristics of the cycloidal pin wheel of the RV-40E reducer were verified by the finite element model.The results show that due to the influence of tooth profile error,the number of meshing teeth is reduced by 1 pair and the meshing stress and transmission error are increased by 5.3％and 5.7％respectively.
