ABSTRACT:
A self regulating continuously variable torque transmission in which two planetary gears of lesser diameter drive two internal gears of greater diameter by orbiting and rotating around an output shaft which forms the rotational axis of the ring gears. Planetary gear orbit is constant while rotation is variable. Loads greater than available torque cause the ring gears to rotate at a lesser velocity than torque input, causing the planetary gears to rotate at a lesser velocity than torque input. To compensate for this, a carrier mounted on the output shaft rotates at a reduced velocity, reducing planetary gear rotation. This carrier provides two diametrically opposed axes, one each for two crankshafts which rotate on these axes during reduced planetary gear rotation, carrying each planetary gear in orbit around a separate axis. These two movements are created by an input crankshaft with one throw and a second crankshaft mounted by bearings on the input throw. The second crankshaft is comprised of two throws, each diametrically opposed to the other relative to the input throw. The second crankshaft transmits torque from the input axis to two separate axes offset from the input axis. Two connecting rods transmit torque from the second crankshaft to the planetary gear crankshafts.
