After designing oil ditches on the surface of its arc - block , increase friction factor and make sure self - lock which solves above problem . do qualitative analysis to lower pair and one - way overrunning clutch and inner star - wheel - roller overrunning clutch by using self - made lever loader . the experiment shows : on the same condition , the deformation of new overrunning clutch ’ s surface contact with lower pair is smaller than the deformation of roller overrunning clutch ’ s line contact with higher pair and new overrunning clutch ’ s skid angle is smaller
对低副单向超越离合器的部件进行了加工制造,在超越离合器弧块表面创新设计加工排油沟,增大摩擦系数,保证实现自锁,解决了很多离合器工作过程中容易出现无法自锁的问题;对低副单向超越离合器和内星轮滚柱超越离合器用自制杠杆加载器做了定性分析,实验表明:相同条件下,新型离合器低副面接触比滚柱离合器高副线接触变形小、溜滑角小。
