ABSTRACT:
A constant velocity joint (10) rotationally connecting rotationally mounted first and second members (12 and 14) together each having an axis of rotation (16 and 18) in accordance with the invention and includes at least one axial bore (42) within the first shaft offset from and parallel to the axis of rotation of the first member, a plurality of axial channels (46) extending along each axial bore which are located in a peripheral wall (44) of each axial bore; at least one axial bore (42) within the second member offset from and parallel to the axis of rotation of the second member, a plurality of channels (46) extending along each axial bore which are located in a peripheral wall (44) of each axial bore of the second member; at least one pair of rods connected together by a joint (28) having at least one degree of rotational freedom, one of the rods of each pair of connected rods being disposed in an axial bore within the first member and another of the rods of each pair of connected rods being disposed in an axial bore within the second member; and a casing containing at least a portion of the first and second members and for containing a fluid lubricating medium which is disposed within the bores and the channels during roation of the members.
