Relative motions of balls, the inner race and the cage to the outer race of the Rzeppa constant velocity joint deviate from their ideal motions due to clearances between pairing elements. In this paper, output angle errors, eccentric motions of the inner race relative to the outer race and three dimensional deviations of the cage relative to the homokinetic plane with several joint angles are experimentally analyzed. The closed loop equations such that three balls may contact simultaneously their inner and outer races with one point or two points and the constraint equation for three balls so as to move in a plane by the cage are solved strictly for prescribed positions of the cage relative to the outer race. The obtained kinematic model of the Rzeppa joint simulates error characteristics of the relationship between input and output angles, which are about sinusoidal with period of 2π or 2π/3 according to the value of joint angle. Consequently, contact positions of three balls and their grooves and relative motions of elements are made clear.
