摘　　要：针对RV减速机传动过程中,其啮合点数无法通过现有设备进行检测的问题。提出首先建立RV减速机关键部位的接触刚度,进而推导出其对应的扭转刚度;其次,根据整机扭转刚度和局部扭转刚度推导出摆线轮与针轮组件间的总啮合刚度,然后使用RV减速机综合试验台检测RV减速机在各负载扭矩下的整机扭转刚度;最后,以摆线轮与针轮间的总扭转刚度值为参考,结合实验实际检测结果,从扭转刚度结果中选取最接近的刚度值作为实际啮合区间,并通过有限元分析验证了理论分析的正确性。Aiming at the problem that during the transmission of theRV reducer,the meshing points cannot be detected by existing equipment. First,the contact stiffness of key parts of RV reducer is established and the corresponding torsional stiffness is deduced. Second,based on the torsional stiffness of the whole machine and local torsional stiffness,the total meshing stiffness between the cycloid and pinwheel components is derived. Then,the torsional stiffness of RV reducer under different load torques is measured by using RV reducer comprehensive test bench. Finally,taken the total torsional stiffness as the reference and combined with the actual test results,the closest stiffness value is selected as the actual meshing area from the torsional stiffness results. The correctness of the theoretical analysis is verified by the finite element analysis.
