技術摘要:
一種螺桿式慣質機構,係包括:一螺桿,該螺桿至少包含有一限位部與一外壁佈設有斜向螺紋之螺紋部;一螺帽,該螺帽係囓合於螺桿之螺紋部上;一慣性體,該慣性體係固著於螺桿之限位部上;以及一連接體,該連接體係囓合於螺桿之限位部,俾使該連接體得以螺桿軸心為旋轉軸心相對於螺桿旋轉,以於一合力不為零之外力施於該慣質機構時,使該螺帽與連接體間產生相對水平位移,進而使該螺帽帶動該螺桿旋轉,又帶動慣性體轉動,以達到慣質之特性。

A screw type inerter mechanism includes a screw with a limit portion and a thread portion with threads; a screw cap engaged with the thread portion of the screw; an inertia body fixed to the limit portion of the screw; and a connection body engaged with the limit portion of the screw wherein an axial of the screw serves as a rotation axial for the screw to rotate relatively to the connection body. Thus, when a non-zero external force is applied to the inerter mechanism to generate relative horizontal displacement between the screw cap and the connection body, the screw cap brings the screw to rotate, which further brings the inertia body to rotate, thereby achieving the inerter features.
