Balancing device for an engine

摘要

A balancing device comprising three or more rotating balancers mounted within a housing is detachably mounted on a reciprocating, internal combustion engine. The balancing device generates a balancing force Fb chosen to cancel the vibrating force Fr produced by the engine. The vibrating force Fr lies on a vibration line S, and the balancing force Fb is spaced a distance l therefrom, whereby a rotating moment M is generated. The balancing device also generates a balancing moment -M, chosen to cancel the rotating moment M.
