ABSTRACT:
A constant velocity joint for transmission of rotary motion between two angularly-displaceable shafts to maintain velocity of a driven shaft equal with a driving shaft regardless of the angular relationship of the two shafts. A ball-shaped member is rotatable about a first axis and is disposed and received in an outer member which is rotatable about a second axis. The ball-shaped member is fabricated from identical stamped metal halves which are welded together to form a hollow ball. Rotary motion is transmitted between the ball-shaped member and the outer member by diametrically opposed cam rollers which are rotatably supported on shafts which are fixedly attached to the outer member. The cam rollers engage flanges which extend inwardly from the edges of slots in the ball-shaped member. The outer member has a cup-shaped socket configuration which is complementally shaped to receive the ball-shaped member. The open end of the outer member includes an annular flange. The ball-shaped member is retained in the outer member by retaining rings which form an inner diameter smaller than the diameter of the ball-shaped member. The retention ring has an axially-extending lip which extends over the outer periphery of the annular flange of the outer member and the assembly is enclosed by a resilient boot seal.
