Centered double universal joint

摘要

A centered double universal joint has a first outer joint yoke (1) carrying a first cylindrical bearing journal (4). A unit including a first bearing ball (6) and a first bearing race (25) are secured on the journal (4). Via a cylindrical outer face (33), first bearing race (25), the unit is positioned in a bearing bore (24) of a guiding projection (23) of a guiding disc (22). Accordingly, a surface to surface contact is achieved between the cylindrical outer face (33) and the bearing bore (24) as well as between the hollow spherical bore (32) of the bearing race (26) and the spherical outer face (17) of the bearing ball (16). The other outer joint yoke is provided with a similar bearing ball and a bearing race arrangement.
