Abstract
A transmission utilizes oscillating torque to vary the mechanical power transmitted to a load. The transmission has a rotatable input member and a rotatable mass. The transmission also has a member with an eccentric offset, with the rotatable mass rotatably coupled to the offset and being eccentric with respect to the offset. The input member is coupled to the rotatable mass by a linkage so that the rotation of the input member causes the rotatable mass to rotate and apply centrifugal force to the member with the eccentric offset. First and second one-way clutches are coupled between the eccentric offset member and an output member. The first one-way clutch drives the output member in one direction and the eccentric offset member is driven in the one direction and the second one-way clutch prevents the output member from rotating in the other direction.
