You don't need to belt.
They way those cones are set up, a gear with widely spaced, narrow teeth would work.
One tooth for each grove.
However the shaft the gear slides on would need to be angled to maintaint a constant distance between the cones. And that would mean a weird free-rotation thing for the gear.
Argh, I spent 3 hours designing a CVT in inventor only to realize "wait a minute, this won't work . . . . . "
Yeah, the gear is out because of teeth. You need a sticky wheel in between them, but not sticky enough to prevent ot from sliding up and down. Argh. Well, at least I learned something.
