Study of Non-uniform Velocity Balancer in the Piston Crank Mechanism

This paper is concerned with a new type of non-uniform velocity balancer appling to the single cylinder engine. A conventional balancer rotate in an uniform velocity,while the new one rotate in a non-uniform velocity. A non-uniform velocity rotation is given by the eccentric gear installed balancer shaft. It is recognized that the moderate eccentricity of gear train is existed for reducing the exciting force and its effect is remarkable.
