摘要:
考虑摆线轮修形量、轮齿接触变形、针齿销弯曲变形的影响,利用赫兹理论计算了针齿与摆线轮不同啮合齿间的接触应力;基于摆线针轮行星传动的啮合原理,采用有限元法精确建立了RV第二级针摆啮合传动的有限元模型,根据针齿固定摆线轮输出的实际工况,对针齿壳外圈节点进行了全约束,采用刚性梁模拟行星架输出机构,使用刚性单元模拟偏心轴曲柄,采用饺链链接技术模拟曲柄相对摆线轮轴承孔的转动,对轴承孔的约束模拟轴承的实际工作情况,在输出机构质心点施加转矩载荷,进而进行摆线针轮啮合接触非线性分析,得到摆线轮的应力、应变云图.理论计算和有限元分析结果进行对比分析,为摆线轮的优化设计提供理论基础和有效的数值模拟方法.
Abstract:
In view of the quantity of cycloidal gear modification,tooth contact deformation and the effects ofthe pin gear bending deformation,the contact stress between the pin gear and the various cycloidal gears iscalculated by Hertz theory. Based on the meshing principles of cycloid pin gear planet transmission,the RVsecond-level finite element model of pin-cycloid meshing transmission is accurately established by using the fi-nite method. According to the actual working condition of fixed pin gear and cycloidal gears outputing,thenodes in the outer ring of the pin gear are constrained,and the rigid beam is employed to simulate the planeteasel output gears. Meanwhile,the rigid cell is employed to simulate the eccentric shaft crank. The hinge linktechnology is employed to simulate the rotation of crank relative to cycloid pin gear hole. Based on the actualworking condition of the constrained and simulated bearing of the bearing bore,a torque load is applied in theoutput unit centroid and the cycloid-pin gear contact nonlinear analysis is further employed to get stress, straimcontours of the eycloidal gear. Comparative analysis of the results of theoretical calculation and finite element a-nalysis offers a theoretical basis for optimal design of cycloid gear and the effective method of numerical simu-lation.
