摘要
利用质量弹簧等价模型方法计算了理想结构下摆线针轮传动的齿面载荷分布。经验证与理论计算方法得到的结果基本吻合,并在此基础上分别探讨了多种加工误差、等距修形引起的间隙等对摆线针轮传动中齿面载荷分布的影响,进而分析了多种加工误差和间隙同时存在时对摆线轮齿面载荷的综合影响关系。提出了一种通过控制偏心轮偏心误差的相位和相关误差量的大小来改善摆线轮齿面载荷分布的方法。
The mass-spring equivalent model of trochoid transmission was established. By using the equivalent model, contact force of ideal trochoid transmission was calculated, and the calculation result agree relatively well with a theoretical one. On the basis of this equivalent model, the effects of many machining tolerances and clearances on the contact force distribution of trochoid transmission was analyzed. Furthermore, the comprehensive effects of several co-existing tolerances and clearances on the contact force distribution was studied. Finally, through the control of the direction of position errors of the crank cam and the amplitude of related tolerances, a valid method was presented to improve the contact force distribution of trochoid transmission.
