Title (EN) FRICTION DAMPER
(FR) AMORTISSEUR À FRICTION
(JA) 摩擦ダンパ
Abstract:
(EN) Provided is a friction damper capable of suitably suppressing entry of foreign matter into a friction surface. A friction damper (1) is provided with a cylinder (10), a rod (20), a friction member (30), an elastic member (40), and a seal member (50). The cylinder (10) is formed like a tube. The rod (20) is capable of freely reciprocating in an axial direction and is partially housed in the cylinder (10). The friction member (30) is arranged inside the cylinder (10) to generate a damping force based on a frictional force generated between the friction member (30) and an outer circumferential surface (20C) of the rod (20) as a result of relative movement between the cylinder (10) and the rod (20). The elastic member (40) applies an elastic force in a direction in which the length of projection of the rod (20) on one end (20A) side from the cylinder (10) increases. The elastic force of the elastic member (40) is applied to the seal member (50). The seal member (50) is held by the elastic member (40) to seal a clearance (CP) through which the outside and the inside of the cylinder (10) communicate with each other.
(FR) L'invention concerne un amortisseur à friction capable de supprimer de manière appropriée l'entrée de corps étrangers dans une surface de friction. Un amortisseur à friction (1) est doté d'un cylindre (10), d'une tige (20), d'un élément de friction (30), d'un élément élastique (40) et d'un élément d'étanchéité (50). Le cylindre (10) présente la forme d'un tube. La tige (20) est capable de se déplacer librement dans une direction axiale et est partiellement reçue dans le cylindre (10). L'élément de friction (30) est agencé à l'intérieur du cylindre (10) pour générer une force d'amortissement sur la base d'une force de friction générée entre l'élément de friction (30) et une surface circonférentielle externe (20) de la tige (20) suite au mouvement relatif entre le cylindre (10) et la tige (20). L'élément élastique (40) applique une force élastique dans une direction dans laquelle la longueur de projection de la tige (20) sur un côté d'extrémité (20A) à partir du cylindre (10) augmente. La force élastique de l'élément élastique (40) est appliquée à l'élément d'étanchéité (50). L'élément d'étanchéité (50) est maintenu par l'élément élastique (40) pour assurer l'étanchéité d'un espace (CP) à travers lequel l'extérieur et l'intérieur du cylindre (10) communiquent l'un avec l'autre.
(JA) 摩擦面への異物の侵入を好適に抑制することができる摩擦ダンパを提供する。 摩擦ダンパ(1)は、シリンダ(10)、ロッド(20)、摩擦部材(30)、弾性部材(40)、及びシール部材(50)を備えている。シリンダ(10)は筒状に形成されている。ロッド(20)は、軸方向に往復移動自在であり、一部がシリンダ(10)に収納されている。摩擦部材(30)は、シリンダ(10)の内部に配置され、シリンダ(10)とロッド(20)の間の相対移動によりロッド(20)の外周面(20C)との間で生じる摩擦力によって減衰力を発生する。弾性部材(40)は、ロッド(20)の一方の端部(20A)側のシリンダ(10)からの突出長さが長くなる方向へ弾性力を付与する。シール部材(50)は、弾性部材(40)の弾性力が付与されており、弾性部材(40)に保持されてシリンダ(10)の外部と内部とを連通する隙間(CP)を封鎖する。
