Abstract
A crankshaft mounted secondary shaking force balancer for multicylinder engines and the like in which eccentrically rotating balance weights carried on the crankshaft and arranged for substantial primary balance are combined in oppositely rotating groups of weights driven by stationary ring or sun gears and associated planetary gears to provide coacting rotating forces that combine to apply directly to the crankshaft a secondary shaking force reciprocating at twice crankshaft speed and available to balance equivalent oppositely directed shaking forces developed by the crankshaft connected moving components of the engine.
