ABSTRACT:
A rotor controlled CVT including: input and output shafts (28,44), an elongated cam-shaped rotor (12) which is uniformly and linearly tapered over its length and is engaged for rotation with the input shaft, a plurality of cam follower units (54) which are located in structure about and are reciprocated by the rotor and include rollers (56) having treads which bear and rotate in circumferential paths on the rotor surface, angular velocity extraction devices (38) which are each engageable and partially rotated by a cam follower, means (14) for causing the extraction devices to collectively produce an output velocity at the output shaft, elements for causing relative movement between the rotor and cam followers to vary the ratio of rotation between the input and output shafts, and elements for keeping the roller treads in contact with the roller surface. The roller treads are in line contact with the rotor surface.
