Centred double universal joint

摘要

The double universal joint has a first outer joint fork carrying a first cylindrical bearing journal (4) for a first bearing ball (6) and first bearing ring (25). This sits with the cylindrical outer surface (33) in a bearing boring (24) of the guide attachment (23) of a guide disk (22) so that there is surface contact between the cylindrical outer surface and the bearing boring on one hand and the hollow-ball boring (32) of the bearing ring and the spherical outer surface (17) of the second bearing ball (16) on the other.
