Abstract
A universal joint comprising a first joint member having a rotational axis and a body connected to the first joint member for pivotal movement relative thereto about a pivot axis intersecting and perpendicular to the rotational axis. The body comprises two trunnions extending along a trunnion axis perpendicular to the pivot axis of the body and respective rollers are carried by the trunnions for rotation about the trunnion axis. The universal joint also comprises a second joint member having a rotational axis and affording two tracks extending lengthwise of the second joint member and diametrically opposed to one another about the rotational axis of the second joint member with the rollers being received in the tracks for torque transmission between the joint members by way of the body and rollers. Also provided for is centering the rotational axes of the first and second joint members relative to one another, and a guide member having respective portions cooperating with the first and second joint members and the body, and operative to maintain the trunnion axis in a plane bisecting the angle between the rotational axes of the first and second joint members.
