Kinematic Analysis and Simulation on VL Telescopic Constant Velocity Universal Joint

The kinematic differential equations are formulated for centers of steel balls in a VL telescopic constant velocity universal joint,which can describe the motion of the steel balls,no matter how the motion between the input and the output shafts is.The kinematic traits of this type joint are analyzed and the kinematic analysis software is developed for VL telescopic constant velocity universal joint.Through the kinematic simulation,some important parameters are obtained,including the relative displacements of the steel ball centers with respect to the orbits and the maximum displacements with respect to the cage slot center in both of radial and tangential directions.These results are helpful in the design of orbit length and cage size of VL telescopic constant velocity universal joint.
