Sliding ball-and-socket joint for coupling of drive shafts has joint bush and joint hub with ball grooves at different angles of contact and inclination

摘要

The joint has a joint bush (2) with inner ball grooves (5), a joint hub (3) with outer ball grooves (6), and one ball (7) for each groove pairing. The ball grooves have different contact angles to the associated rotary axis (A, B) in peripheral extension of bush resp. hub, and different angles of inclination in longitudinal direction relative to an imaginary cylinder jacket about a rotary axis. Ball grooves located next to each other in peripheral direction are differentiated by the contact angles and/or the inclination angle.
