摘　　要：以RV-40E减速器各个针摆啮合齿对受力为研究对象,应用APDL参数化编程语言,建立RV-40E型号含摆线轮、针齿、针齿壳、轴承等单元的有限元分析模型,以曲柄轴转动360°时一个针摆啮合小周期传动为条件进行有限元动态仿真,得到了针摆传动的最大接触应力值随曲柄轴转角变化的历程曲线,分析了针齿沿摆线轮齿根到齿顶连续动态啮合的接触应力变化规律,与计算得到的RV减速器摆线针轮传动理论啮合力进行对比,符合接触应力的变化规律,验证了该APDL的参数化有限元模型的合理性.Aiming at the force of each pendulum meshing tooth pair of the RV-40E reducer,the APDL parameterized programming language was used to establish the finite element analysis model of the RV-40E model including cycloid wheel,pin gear,pin gear shell,bearing and other units,based on the condition that a pin pendulum meshes with a small-period transmission when the crank shaft rotates 360o.The finite element dynamic simulation was performed,and the maximum contact stress of the pin pendulum transmission and the history curve varying with the crank shaft angle are obtained.The contact stress variation law of the continuous dynamic meshing of the needle teeth along the cycloidal gear tooth root to the tooth tip is analyzed and compared with the calculated theoretical meshing force of the cycloidal pinwheel transmission of the RV reducer,which conforms to the variation law of the contact stress and verifies the rationality of APDL parameterized finite element model.
