Abstract
The universal joint coupling comprises a housing (,) in which a torque transmitting pair of coupling members is arranged between two axial force transmitting pairs of coupling members (,), each of which includes a spherical cup (,) and a ball segment (,) supported therein. The torque transmitting pair of coupling members (,) has grooves which are arranged in two concentric rows and are defined by gaps in an internal gear ring (,) fitted into the housing (,), or an external toothing (,). They cooperate for torque transmission with counter-acting bodies, the profile of which matches the groove profile. Both the external toothing (,) and the ball segments (,) form part of a hub (,). At least the spherical cup (,) of the axial force transmitting pair of coupling members (,) which is higher loaded during normal operation, and the internal gear ring (,), on the one hand, and on the other hand the internal gear ring (,) and the hub (,) are connected to each other such that their positions relative to each other resulting after having assembled the universal joint coupling for the first time can be reproduced clearly and reliably thereby increasing the service life of the universal joint coupling.
