RV减速器螺栓受力仿真分析

SIMULATION ANALYSIS OF RV REDUCER BOLT FORCE

螺栓是RV减速器主要连接部件,其力学性能影响着整机的传动精度。根据摆线轮齿廓生成原理,结合矢量法建立修形后摆线轮齿廓方程;应用变形协调原理,对整机各构件进行力学分析,在理论上计算螺栓受力;在考虑摆线轮修形、针齿中心圆直径误差的情况下,在Adams中进行多体动力学分析,通过仿真分析可知:不同的初始安装角度或不同转动角度,各螺栓变化趋势不同,且变化幅度不同;不同转动角度,螺栓受力大小顺序不相同;随摆线轮转动角度增大,螺栓总体受力先增大后减小;随着负载的增大,螺栓受力逐渐增大,且随着负载增大,增大幅度也逐渐增大。

The bolt is the main connecting part of the RV reducer.Its mechanical properties affect the transmission accuracy of the whole machine.According to the principle of generating the profile of the cycloidal gear.Combining vector method to establish the profile equation of cycloidal wheel after shaping.Apply the principle of deformation coordination.Mechanical analysis of each component of the whole machine.Calculate the force of the bolt in theory;Considering the modification of the cycloidal wheel and the diameter error of the center circle of the pin tooth.Multi-body dynamics analysis in ADAMS.Through simulation analysis,we can know:Different initial mounting angles or different angles of rotation.Different bolts have different trends and different degrees of change.Different angles of rotation.Bolt force is not in the same order.As the angle of rotation of the cycloid increases,the overall force of the bolt increases first and then decreases.As the load increases,the bolt is gradually increased in force.As the load increases,the magnitude of the increase also increases.
