- Red bar and yellow shaft create a joint of class II (allowing four degrees of freedom).
Red bar and green shaft create a joint of class II.
Red bar and blue retainer create a spherical joint.
With this arrangement, the plane containing ball centers almost always remains in a plane that bisects the angle α between the two shafts when α changes. See: "Slider crank and coulisse mechanism 1"

The video shows the transmission when α is 0 deg. and then 30 deg.
The output shaft rotates nearly regularly with max error of 1.5% at α = 30 deg.

Question: Apart from the need to share the loads evenly, Is there any other reason for the Rzeppa joint to have the balls fixed to the bisector plane at all times? I have done this by allowing the balls to move at a perpendicular plane to one shaft while gaining ALL the inclination from sliding motions in the second shaft. This also seems to produce constant velocity. Please let me know your view.
So, i'm sorry if this answer comes late, but i've just seen your comment. The thing is: by having the balls fixed to the bisector plane, the joint is HOMOKINETIC, which means that its trasmission ratio is 1.
Hey, can you tell me what program did you use to make it?
It is Autodesk Inventor.
What is the red element?
It is called pilot lever.
