ABSTRACT:
A universal joint (150) includes a centering device (160) for maintaining the joint at constant velocity. Each shaft (101) of the joint (150) is connected to a centering device (160). Movement of one of the shafts (101) at an angle relative to the longitudinal axis of the coupling device (117) is transmitted to the other shaft (101) by the centering device (160) and the centering device (160) causes the other shaft (101) to likewise move at the same angle relative to the longitudinal axis of the coupling device (117). The centering device (160) includes an epicyclic bearing (106) within an epicyclic bearing (105), which arrangement of epicyclic bearings allows a full range of movement of the shafts (101).
