Dynamic Response of High-Speed Oblique Overrunning Clutch Wedge
Aiming at the actual situation that the high-speed wedging of the oblique overrunning clutch is prone to failures,this paper studies the dynamic process of its wedging.During the working process,there are collisions between the internal wedges,between the wedges and the inner and outer rings,and between the components and the cage.Firstly,the collision stiffness is solved based on the Hertz contact theory.Then the evaluation indexes are established,including the wedging delay time,impact torque,maximum speed difference,etc.,to determine the degree of influence of the dynamic response of the overrunning clutch.At the same time,the wedging dynamic process of the high-speed overrunning clutch is divided to study the influence of the geometric parameters on different response stages.Finally,the friction conditions between the wedge and the inner ring,spring force,collision stiffness,damping and load are studied on the dynamic response of the high-speed oblique overrunning clutch.The results show that different parameters have different degrees of influence on the defined evaluation indicators,which can lead to wedging failure in extreme cases.
