GENERAL-METHOD FOR ACTIVE BALANCING OF COMBINED SHAKING MOMENT AND TORQUE FLUCTUATIONS IN PLANAR LINKAGES

The paper describes a novel method of active balancing designed to eliminate completely the shaking moment, the driving torque or both simultaneously. Active balancing is achieved by a single additional member: a balancerdisc revolving in a prescribed way related to the geometry and the mass characteristics of the original linkage. Noncircularr gear drive or other means may provide the necessary rotation. The synthesis of the balancing device is based on simple general principles equally applicable for any planar mechanism. © 1990.
