マスダンパ
Document Type and Number:
Japanese Patent JP6762837
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a mass damper capable of changing a rotary inertia mass of a rotary mass and improving the simplification of a configuration and maintainability.SOLUTION: The mass damper includes: a cylinder 2 with a viscous fluid HF filled; a piston 3 provided in the cylinder 2 slidably in an axial direction to partition the inside of the cylinder 2 into a first fluid chamber 2d and a second fluid chamber 2e; a first communication passage 5 and a second communication passage 6 provided mutually side by side to bypass the piston 3, communicate with the first and second fluid chambers 2d, 2e and have the viscous fluid HF filled; a gear motor M provided in the first communication passage 5 to actuate by the viscous fluid HF flowing in the first communication path 5; a rotary mass 21 to be rotationally driven by the gear motor M; a gear pump P provided in the second communication passage 6 to adjust the flow rate of the viscous fluid HF flowing in the second communication passage 6; and a control device 51 for controlling operation of the gear pump P.SELECTED DRAWING: Figure 1
