Friction Cone Variator

Input: the green shaft of one fixed cone and one sliding cone.
Output: the pink shaft of one fixed cone and one sliding cone.
Thre orange ring contacts with all cones.
The blue bar can move the sliding cones to change contact positions of the ring for desired output velocity.
The pressure at contact places is created by choosing right value of the ring inside diameter.
Two cones on each shaft can be assembled back to back (instead of face to face) with appropriate section of the ring in embodiments of this variator.
