摘要: 介绍了一种新型的围带滚柱式超越离合器工作原理,运用运动学仿真软件MSC.ADAMS和有限元分析软件ANSYS对其进行动力学仿真和关键零件的强度仿真,定量分析了各因素对离合器性能的影响。结果表明:适当增大滚柱与内座圈和外座圈之间的摩擦系数,可以略微减小滚柱楔合时的瞬时挤压力和空转角;滚柱数量的增多对离合器的承载性能有明显的提高;弹簧力的大小对滚柱受力没有影响,弹簧力越大,空转角越小。Abstract: The working principles of a new kind of retainer-roller-eccentric arc type overrunning clutch are presented.The effects of various factors on the clutch's performance are investigated quantitatively;its dynamic characteristics and its key components' strength are simulated with MSC.ADAMS and ANSYS.The simulation results indicate that: 1) the idle angle and transient stress of the roller decrease slightly with the proper increase of coefficients of friction among the roller,inner seat and outer seat;2) the increasing number of rollers significantly enhances the load-bearing capacity of the overrunning clutch;3) the larger the spring force,the smaller the idle angle,indicating that the spring force has little effect on the stress of the roller.The simulation results coincide with the actual working of the overrunning clutch.
