ABSTRACT:
A power transmission for engines, motors, pumps and the like comprises a power shaft mounted to rotate about a fixed axis, an eccentric in the form of a tapered bar having arcuate ends secured on the power shaft to turn therewith, a power transmission ring having a circular internal bearing surface contacting the arcuate ends of the eccentric, a plurality of cranks connected to the power transmission ring by crankpins, each crank having a crankshaft journaled to turn about a fixed axis which is parallel to the power shaft. Power may be applied to any of the crankshafts by a motor coupled to the crankshaft or power may be applied to any crankpin by a pitman connecting the piston of an internal combustion engine or fluid motor to the crankpin. In either case, the power applied imparts non-rotary, planetary motion to the power transmission ring to turn the eccentric about the axis of the power shaft, thereby rotating the power shaft at the same speed at which each of the cranks is rotated but with more torque. In a modified form, the transmission ring may be provided with internal gear teeth, and through a cooperating gearing a secondary power shaft may be driven in the same or in the opposite direction relative to the primary power shaft and at a different speed.
