A high torque universal joint has a cross (10) formed by two mutually perpendicular pairs of coaxial trunnions (11), each pair of trunnions being rotatably received in bearings (26) which in turn are coaxially retained in blind bores (24) in the bearing caps (22) of one of two yokes (12, 12 min ). The yokes are subdivided into mating half sections (12a, 12b) which each include one of the bearing caps. The mating half sections are separably interconnected (48, 50) and are provided with juxtaposed confronting surfaces (38) lying on opposite sides of first yoke reference planes extending through the universal joint center (X). The mating half sections have end surfaces (52) which are adapted to abut the flanged ends (18) of rotatable elements (20) at second yoke reference planes. The first and second reference planes of each yoke are mutually perpendicular, and first and second key members (44, 54) are located respectively at the first and second reference planes. The restraining forces acting at the first and second yoke reference planes coact during service of the joint to prevent relative movement between the mating yoke half sections. |
