Re: pic: CVT drivetrain

The problem with gears in CVTs is that with a varying diameter comes either one of two things:

A varying pitch, or
A varying number of teeth

And I don't see how either circumstances could properly mesh with another gear. That's why I've never seen an actual cone shaped gear and that is why most CVTs are friction based.

The only thing I've seen that is close to being a mechanical CVT was the ThunderChickens CCT which used a motor to drive the ring gear of the planetary as well as the sun.
