ABSTRACT:
In an angularly movable universal joint, a ring of balls extends around the axis of rotation of the joint with the balls being radially movably supported in bores in the inner joint member and guided within grooves in the outer joint member. Adjacent balls are in contact with one another through intercommunicating openings between adjacent bores. The area of the material of the inner joint member in a plane extending perpendicularly of the axis of rotation and including the centers of the balls is greater than zero but less than the maximum area of the cross section remaining when the rectangular area of the bores plus areas defined between the inner ends of the rectangular areas of the bores and a circular arc having a radius of the bores is removed.
