ABSTRACT:
The principle of dual concentricity is described and utilized within a Dual Concentric Positively Infinitely Variable transmission; a true all-geared torque-converting positively infinitely variable transmission which utilizes a user actuated independent input control to vary the transmission output. The input control varys the orbital relationship and effective gear ratio between a driving ring gear and a driven pinion gear causing both gears to variably orbit the mechanism central axis to produce an output receiving gear and connected output shaft torque converting speed range operating between a geared neutral stopped position and its maximum output speed.
