If I were to simply make it a wheel, I would rather coat the whole disk with rubber, and make an insane amount of grooves.

NOTE: For future reference, the yellow dome, and green circle are gears. The dome has teeth like a normal gear, it's just spaced in a funky way.

Those blue bars are I call floating sprocket bars ( Note that there is no water involved ) They are made of steel or some other similar material. It's supposed to enable this CVT to have positive drive as opposed to a friction drive.

They are meant to maintain contact with the gear. This allows it to slide back and forth without breaking any teeth.

Here is a cross section of those floating sprocket bars.





With those bars, I can have a positive drive CVT. This design--if it is actually possible--should be more efficient than the other thread about a CVT made by a fellow Team 19 freshman.

Here is something that explains the concept.
