Abstract
This disclosure relates to a balancing mechanism for preventing vibration of a reciprocating piston internal combustion engine. The balancing comprises a pair of eccentric journals on the crankshaft, each having an axis spaced to the side of the crankshaft axis which is opposite the crankpin. A pair of arms are journaled on the journals and carry a counterbalance. Guide means is mounted in the crankcase for confining the counterweight to reciprocate on the cylinder axis in directions reverse to the piston motion as the crankshaft rotates.
