Abstract:
A vibration reduction device ( 5 ) including: a counterweight ( 6 ) provided to a crankshaft ( 14 ) of a Stirling engine ( 1 ); and an electric balancer ( 7 ) being attached to a crankcase ( 15 ) and including a balance weight ( 73 ) rotated by an electric motor ( 74 ). An inertial force of the counterweight ( 6 ) is set to approximately a half of a combined inertial force of pistons ( 12, 13 ). Inertial force of balance weight×L2=½×combined inertial force of pistons×L1 is satisfied when a mass of the balance weight is set, where L1 denotes a distance between a vibration reduction target position and a rotation center (O 1 ) of the crankshaft ( 14 ), and L2 denotes a distance between the vibration reduction target position and a rotation center (O 2 ) of the balance weight ( 73 ).

Claim (Index 2):
A vibration reduction device comprising:\n a counterweight provided to a crankshaft driven by a reciprocating movement of a piston of a reciprocating engine; and a balancer including a balance shaft driven independently from the crankshaft and a balance weight that is provided to the balance shaft and is integrally rotatable with the balance shaft, wherein an inertial force of the counterweight is set at approximately a half of a combined inertial force of the piston, and a mass of the balance weight is set so that the following formula is established:\n inertial force of balance weight\u00d7 L 2=\u00bd\u00d7combined inertial force of pistons\u00d7 L 1 \n where L1 denotes a distance between a vibration reduction target position and a rotation center of the crankshaft and L2 denotes a distance between the vibration reduction target position and a rotation center of the balance weight.
