Abstract:

The motion equations were established by means of spatial geometric projection method.The equation for relationship between phase angular of flange yokes on two ends of jackshaft and transmission ratio was deduced.Hereafter,the influence of true joint angles and phase angle in a  double cardan universal joint on the instantaneous transmission ratio and the rotation angle difference was analyzed,besides the influence of the initial angle on the rotation angle difference.The results indicate that the rotation angle difference and the rotation speed difference are periodic functions of rotation angle about input angle.The amplitude of rotation angle difference and the amplitude of the rotation speed difference increase with the phase angle.The amplitude of rotation angle difference and the amplitude of rotation speed difference increase with the true joint angles.

Key words: double Hooke universal joint, instantaneous transmission ration, flange yoke, phase angular, rotation angle difference
