Design of Balancer Shaft in High Speed Reciprocated Internal Comnbustion Engine

There are unbalanced inertia force and torque in the reciproca te d internal combustion engine,so the engine will have marked vibration and noise when it runs at high speed.The vibration and noise of highspeed reciprocated int ernal combustion engine can be markedly reduced with a balancer shaft. In this p a per the lowest mass design principle and the errorness of the balancer system ar e analyzed.It mainly discusses the influence of such structural parameters as ro tation radius,width and included angle on the mass of fan type balancer,with the prerequisite of balancing the same inertia force or torque.
