Kinematic and Experimental Analysis of the Double-Offset Type Constant Velocity Joint 960724

The kinematic model of a generalized double-offset joint(DOJ) is presented. The relationship between the input and output angles of DOJ may be analyzed by solving the quartic equation for the angular displacement from the output shaft to the normal of the homokinetic plane. The sensitivities of the output angle are evaluated and the cause for the output angle error is investigated with the kinematic constants curves. A method is presented for simulating the relationship between the input and output angles in the case where there exist a clearances between an inner-race and the balls. Moreover, the relationship between the input and output angles of the actual DOJ and the deviation of the input axis relative to the output axis are precisely measured, and the case of the output angle error is investigated by the simulation the cause of output angle error.
