ABSTRACT:
A mechanical mechanism, for use in an internal combustion engine for changing rectilinear movement of a piston to rotational movement of a crankshaft, is of simple construction and has a minimum number of parts. A small gear with teeth formed on its external peripheral portion is stationarily mounted to a wall of an engine, and receives a first portion of a crankshaft, the crankshaft being rotatable with respect to the gear and the wall about an axis. A second portion of the crankshaft opposite the first is also mounted for rotation with respect to a stationary member. A third portion of the crankshaft is offset from the axis. A balancing structure comprising first and second balance bodies interconnected by a collar, and is mounted so that the crankshaft third portion is received within the collar and rotatable with resepct to the collar. The first balance body has an interior peripheral portion with gear teeth extending radially inwardly, those gear teeth intermeshing with the small gear continuously as the collar revolves around the crankshaft axis. Bearings interconnect the collar to one or more pistons.
