Title:
VIBRATION REDUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/145795
Kind Code:
A1
Abstract:
This vibration reduction device (5) comprises: a counter weight (6) provided to a crank shaft (14) of a Stirling engine (1); and an electrically-driven balancer (7) having a balance weight (73) that is rotated by an electric motor (74) mounted to a crankcase (15). The inertial force of the counter weight (6) is set approximately to one half of the combined inertial force of pistons (12, 13). Inertial force of balance weight × L2 = 1/2 × combined inertial force of pistons × L1 is satisfied, when L1 represents the distance between a vibration reduction target position and the rotation center (O1) of the crank shaft (14), and L2 represents the distance between the vibration reduction target position and the rotation center (O2) of the balance weight (73).
