Abstract
A technique for providing a variable-ratio coupling between output shaft and input motor involves driving an output shaft with drivers that are out of phase with each other. Advantageously, the technique provides a gear reduction via a simple, high-efficiency mechanism; continuous output torque is provided by alternating the load between two belts deflected by, by way of example but not limitation, cam devices.
