Abstract:

This paper puts forward a new mothod of balancing the big reciprocating inertia force of gang saw with the altering angular velocity of the shock attenuation device. The study and calculation indicate: the method can balance the reciprecating force by 99%; decrease the maximum reciprocating inertia force by 268 times and by 90 times over the present balancing method with counterbalance. Thus, the gang saw can elimlnate the vibration caused by impact, increase its tangential velocity and productivity of labor and the stability of the frame, This method provides the eneoretical base for ideal balanced gang saw.

Key words: Gang saw, Balancing axle, Inertia force, Altering angular velocity, Eccentric counterbalance, Equidifferent and equivalent principle
