Title (EN) LINEAR DAMPER AND ROTARY DAMPER
(FR) AMORTISSEUR LINÉAIRE ET AMORTISSEUR ROTATIF
(JA) 直動ダンパ及びロータリーダンパ
Abstract:
(EN) Provided are a linear damper and a rotary damper which have desired damping characteristics and a simple structure. These dampers (1) are provided with a cylinder (4), a rod (50), and a plurality of granular bodies (90). The cylinder (40) has a first space (S11) formed therein. The rod (50) is partially accommodated inside the first space (S11) and protrudes to the outside. In addition, the rod (50) can reciprocate relative to the cylinder (40) in the center axis direction. Furthermore, the rod (50) forms a filling space (S1), between the rod (50) and the cylinder (40), inside the first space (S11). The plurality of granular bodies (90) are filled in the filling space (S1). In addition, the shape and area of the cross-section, in a direction perpendicular to the central axis, at a predetermined position in the central axis direction of the rod (50) changes according to the movement of the rod (50).
(FR) L'invention concerne un amortisseur linéaire et un amortisseur rotatif qui présentent des caractéristiques d'amortissement souhaitées et une structure simple. Lesdits amortisseurs (1) sont pourvus d'un cylindre (4), d'une tige (50) et d'une pluralité de corps granulaires (90). Le cylindre (40) contient un premier espace (S11). La tige (50) est partiellement logée dans le premier espace (S11) et fait saillie vers l'extérieur. De plus, la tige (50) peut effectuer un mouvement de va-et-vient par rapport au cylindre (40) dans la direction de l'axe central. En outre, la tige (50) forme un espace de remplissage (S1), entre la tige (50) et le cylindre (40), dans le premier espace (S11). La pluralité de corps granulaires (90) sont placés dans l'espace de remplissage (S1). De plus, la forme et la surface de la section transversale, dans une direction perpendiculaire à l'axe central, à une position prédéterminée dans la direction d'axe central de la tige (50), changent en fonction du mouvement de la tige (50).
(JA) 簡易な構造で所望の減衰特性を有した直動ダンパ及びロータリーダンパを提供する。 ダンパ(1)は、シリンダ(40)、ロッド(50)、及び複数の粒状体(90)を備えている。シリンダ(40)は内部に第1空間(S11)が形成されている。ロッド(50)は第1空間(S11)内に一部が収納されて外部に突出している。また、ロッド(50)はシリンダ(40)に対して中心軸方向に往復移動自在である。また、ロッド(50)は第1空間(S11)内でシリンダ(40)との間に充填空間(S1)を形成している。複数の粒状体(90)は充填空間(S1)に充填される。また、ロッド(50)の中心軸方向の所定の位置における中心軸に直交する方向の断面形状及び断面積が、ロッド(50)の移動に伴って変化する。
