Title
(EN) SEAL RING
(FR) BAGUE D'ÉTANCHÉITÉ
(JA) シールリング
Abstract
(EN) Provided is a seal ring capable of providing a stable lubrication performance in a wide rotation range. The seal ring 1 provides a shaft-seal in a gap between a rotating shaft 2 and a housing 3, and includes a plurality of static grooves 13 which are arranged in a slide surface S1 in the circumferential direction, open on the side of a fluid to be sealed, closed on the radially outer side, and formed so as to be narrower in the circumferential direction.
(FR) L'invention concerne une bague d'étanchéité pouvant fournir des performances de lubrification stables dans une large plage de rotation. La bague d'étanchéité 1 fournit un joint d'arbre dans un espace entre un arbre rotatif 2 et un boîtier 3, et comprend une pluralité de rainures statiques 13 qui sont agencées dans une surface de coulissement S1 dans la direction circonférentielle, ouvertes sur le côté d'un fluide à étanchéifier, fermées sur le côté radialement extérieur, et formées de manière à être plus étroites dans la direction circonférentielle.
(JA) 広い回転域で安定した潤滑性能を発揮できるシールリングを提供する。 回転軸2とハウジング3との間の隙間を軸封するシールリング1であって、摺動面S1には、周方向に複数配置され被密封流体側に開口し外径側に閉塞し周方向に幅狭に形成される静圧溝13が設けられている。
