ABSTRACT:
A nutating cone transmission is characterized by a flexible speed control ring for controlling the rotational speed of the cone about its axis. The ring is mounted adjacent to the cone with a portion thereof in contact with and depressed by the surface of the cone. A displacement mechanism laterally displaces the ring relative to the cone while preventing rotational movement of the ring and slippage between the ring and the cone. The position of the ring relative to the diameter of the cone controls the rotational speed of the cone which is delivered to an output. The flexible speed control ring increases the reliability and efficiency of the transmission by eliminating slippage between the ring and damage to the cone through wear.
