CV Joints Vs. U-joints, Here's why they invented the CV

[Racey]

Check out this Solidworks Animation, Left Side input is constant speed, Watch the speed variation at the output on the right. This is the best visualization of the effect I've ever seen.

That's why you don't want to run drives too high even though it's a double Cardan unit.

That's a great animation. I just put some RCV shafts in the front axle of my Jeep, what a difference!

What trips me out is how many people don't know that CV stands for constant velocity.

That is amazing animation. Outrageous stuff.

But with the driven side speeding up and slowing down, doesn't that make the driven device go fast-slow, fast-slow, fast-slow?

Yes, and it translates into vibration. The higher the angle the greater the vibration. It goes unnoticed when the angles are low enough.

I've not seen a Cv like this before, what application was/is this used for ?
The CV's using "Ball Bearings" I don't believe accelerate/decelerate like the one shown.
The one shown would come apart very rapidly IMO.

The animation above is a u joint not a cv. It's showing why a cv is better.
