CV Joint (coupling) Question
CV Joint (coupling) Question
(OP)
I am researching max possible torque for a design for a cv joint. My question is: There are ball groove type with splines and just ball groove designs. Which design would produce the most torque? If there is anything you need to know more just ask. Thank you for responding in advanced.





RE: CV Joint (coupling) Question
Do you want the spline to be able accommodate "plunge' motion? Some CV joints do that by themselves. Plain Splines don;t like to slide when transmitting torque.

Most CV joints I know don't allow axial movement, hence if you need axial movement you need splines and if you don't then don't have them.
Rather vague question I'm afraid.

Tmoose also pointed out that plain splines don't like to slide under load, so ball splines are sometimes used.
There are other ways to deal with the changing shaft length problem. Later Corvairs and many Corvettes omitted a lateral link, so that the half-shaft itself acted as its own lateral link. AFAIK, no one has done that with a CV joint, only Cardan joints, because Cardan joints can carry a substantial axial load, and most CV joints cannot.

I believe the inboard end of FWD car driveshafts often use "tripod" CV joints that can accept over an inch of "plunge"/axial motion.

If you are talking about the spline that transmits torque to the CV then, more surface area means more strength, but it is harder to slide.
