Abstract:
To provide a rotary inertia mass damper, which is capable of reducing an axial reaction force that is generated due to vibration having an excessive acceleration to the extent possible when the vibration is input, and of preventing breakage of the damper itself or a construction, provided is a rotary inertia mass damper, including: a first coupling portion, which is fixed to a first structure; a second coupling portion, which is coupled to a second structure; a screw shaft, which has one axial end connected to the first coupling portion and retained so as to be non-rotatable; a fixed barrel, which has a hollow portion for receiving the screw shaft, and is connected to the second coupling portion; and a rotary body, which is retained so as to be freely rotatable relative to the fixed barrel, is threadedly engaged with the screw shaft, and is configured to reciprocally rotate in accordance with advancing and retreating movement of the screw shaft relative to the fixed barrel. A torque limiting member is provided between an axial end of the screw shaft and the first coupling portion, and is configured to, when a rotational torque that exceeds a predetermined value is applied to the screw shaft, allow rotation of the screw shaft relative to the first coupling portion to reduce a rotation angle of the rotary body.

Claim (Index 1):
A rotary inertia mass damper, comprising:\n a first coupling portion, which is fixed to a first structure; a second coup-Xing portion, which is coupled to a second structure; a screw shaft, which has a spiral thread groove formed in an outer peripheral surface of the screw shaft at a predetermined lead, and has one axial end connected to the first coupling portion, and retained so as to be non-rotatable; a fixed barrel, which has a hollow portion for receiving the screw shaft, and is connected to the second coupling portion; and a rotary body, which is retained so as to be freely rotatable relative to the fixed barrel, is threadedly engaged with the screw shaft, and is configured to reciprocally rotate in accordance with advancing and retreating movement of the screw shaft relative to the fixed barrel, the rotary inertia mass damper being configured to damp vibration energy applied between the first structure and the second structure by imparting a rotation angle, which is uniquely determined by a change in distance between the first coupling portion and the second coupling portion and the lead of the screw shaft, to the rotary body, the rotary inertia mass damper further comprising a torque limiting member, which is provided between an axial end of the screw shaft and the first coupling portion, and is configured to, when a rotational torque that exceeds a predetermined value is applied to the screw shaft, allow rotation of the screw shaft relative to the first coupling portion to reduce a rotation angle of the rotary body.
