本文介绍用有限元分析和实验探索超越离合器的(土)形轨道形状对滑动转矩的影响,同时还讨论了其加工偏差对滑动转矩的影响。在有限元分析中采用接触元件模拟环和滚子之间接触。在有限元分析中采用的摩擦系数由试验结果估算。仿真结果表明,超越离合器(土)形轨道形状和加工偏差是设计滑动转矩的重要因素。 In this paper, finite element analysis and experiments are used to explore the influence of the shape of the orbital clutch over the clutch on the sliding torque. The influence of machining deviation on the sliding torque is also discussed. In the finite element analysis, the contact element is used to simulate the contact between the ring and the roller. The friction coefficient used in the finite element analysis is estimated from the test results. The simulation results show that the shape of the overrunning clutch track and the machining deviation are important factors in designing the sliding torque.
