The displacement system for an articulated joint comprises an inner hub (4), around whose outer surface ball bearings (6) are mounted which fit into the inner surface of an annular exterior hub (7). A displacement unit is mounted around the outer hub and has smaller ball bearings (13) in a cage (14) which can slide over its outer surface. An independent claim is included for transmission shafts fitted with the displacement system. |
