ROTATIONAL INERTIA MASS DAMPER
PROBLEM TO BE SOLVED: To provide a rotational inertial mass damper capable of sufficiently obtaining inertial force resulting from a rotational inertia mass of a rotary mass, with its weight reduced.SOLUTION: A rotational inertia mass damper 1 includes: a stationary part 2 coupled to a predetermined first portion within a system including a structure; a screw shaft 4 provided so as to be axially movable to the stationary part 2, and coupled to a predetermined second portion within the system; a nut 5 rotatably screwed into the screw shaft 4 through a plurality of balls, and configured to convert axial movement of the screw shaft 4 to the stationary part 2 into rotational motion; rotary masses 7, 7 freely rotating; and a speed increasing mechanism 8 configured to transmit rotation of the nut 5 to the rotary masses 7, 7 in a state of increasing its speed.SELECTED DRAWING: Figure 1
【課題】軽量化を図りながら、回転マスの回転慣性質量による慣性力を十分に得ることができる回転慣性質量ダンパを提供する。【解決手段】回転慣性質量ダンパ１は、構造物を含む系内の所定の第１部位に連結される固定部２と、固定部２に対して軸線方向に移動自在に設けられ、系内の所定の第２部位に連結されるねじ軸４と、ねじ軸４に、複数のボールを介して回転自在に螺合するとともに、固定部２に対するねじ軸４の軸線方向の移動を回転運動に変換するナット５と、回転自在の回転マス７、７と、ナット５の回転を増速した状態で回転マス７、７に伝達する増速機構８と、を備える。【選択図】図１
