Title (EN) SEAL STRUCTURE AND MANUFACTURING METHOD THEREOF
(FR) STRUCTURE DE JOINT D'ÉTANCHÉITÉ ET SON PROCÉDÉ DE FABRICATION
(JA) シール構造及びその製造方法
Abstract:
(EN) This seal structure 1 is provided with an annular seal member 2, a shaft member 4 having a seal groove 5 where the inner peripheral side of said seal member 2 is arranged, and an inner peripheral wall member 6 which has an internal space 62 surrounded by an inner peripheral wall 61, wherein the shaft member 4 is arranged in the internal space 62, and the annular seal member 2 is arranged in the seal groove 5 of the shaft member 4. The side of the outer periphery 21 of the annular seal member 2 is formed by overlapping, in the axial direction D1, a plurality of ring-shape parts 3 which are closed or unclosed when viewed in a radial direction D2; when viewed in the radial direction D2, on one side of a center axis C1 of the annular seal member 2, in a longitudinal cross-section of the plurality of ring-shape parts 3, one corner 32 of the two corners of the edge 31 facing the inner peripheral wall 61 of the inner peripheral wall member 6 contacts the inner peripheral wall 61 of the inner peripheral wall member 6.
(FR) La présente invention concerne une structure de joint d'étanchéité (1) pourvue d'un élément joint d'étanchéité annulaire (2), d'un élément arbre (4) ayant une rainure pour joint (5) dans laquelle le côté périphérique interne dudit élément joint étanchéité (2) est disposé, et un élément paroi périphérique interne (6) qui a un espace interne (62) entouré par une paroi périphérique interne (61), l'élément arbre (4) étant disposé dans l'espace interne (62), et l'élément joint d'étanchéité annulaire (2) étant disposé dans la rainure pour joint (5) de l'élément arbre (4). Le côté de la périphérie externe (21) de l'élément joint d'étanchéité annulaire (2) est formé par chevauchement, dans la direction axiale D1, d'une pluralité de parties en forme d'anneau (3) qui sont fermées ou non lorsqu'elles sont vues dans une direction radiale D2 ; lorsqu'elles sont vues dans la direction radiale D2, un côté d'un axe central C1 de l'élément joint d'étanchéité annulaire (2), dans une section transversale longitudinale de la pluralité de parties en forme d'anneau (3), un coin (32) des deux coins du bord (31) faisant face à la paroi périphérique interne (61) de l'élément paroi périphérique interne (6) entre en contact avec la paroi périphérique interne (61) de l'élément paroi périphérique interne (6).
(JA) 環状の環状シール部材2と、その内周部の側が配置されるシール溝5を有する軸部材4と、内周壁61に包囲される内部空間62を有し、環状シール部材2がシール溝5に配置された軸部材4を内部空間62に配置する内周壁部材6と、を備えるシール構造1である。環状シール部材2の外周部21の側は、径方向D2に視たときに閉じた又は閉じていないリング形状部3が複数、軸方向D1に重なることにより、形成され、径方向D2に視たときに、環状シール部材2の中心軸C1に対して一方の側において、複数のリング形状部3の縦断面における、内周壁部材6の内周壁61に対向する辺31を含む2つの角部のうちの一方の角部32は、内周壁部材6の内周壁61に当接している。
