ABSTRACT:
To reduce space requirements, vibrations and certain stresses in a motion converting mechanism, a rod is constrained to reciprocate within a housing where the rod is attached to the crankshaft by a cylindrical shaped connector that orbits around the crankpin in a direction opposite that of the crankshaft while rotating inside the rod. Through the center portion of each stroke, the connector also interfaces directly with the housing by such means as a cam cam-follower or gearing to eliminate a second degree of freedom at midstroke. The resulting motion defined for the center of the connector and the rod is sinusoidal being twice that of the motion of the crankpin in the axis of reciprocation. The resulting stroke is four times the crankpin offset.
