Ball joints are widely used in many applications. This paper describes the contact and kinematic analysis of an Rzeppa type constant-velocity joint (CV-joint). Starting from a conveniently simplified 3D model, at fixed joint angle of 45°, a CV-joint made of all “generic steel” components has been studied. Considering only a “perfect” geometry (i.e. not affected by tolerances), suitable contact pairs have been defined to reflect mutual interaction among joint components. Rotation has been imposed to inner race and a suitable resisting torque has been applied to outer race to reproduce the working conditions in a typical application.
