(FR) JOINT DE SEGMENT
(JA) セグメントシール
Abstract:
(EN) A segment seal is provided with which it is possible to prevent incorrect attachment of a pair of seal rings in a tandem segment seal. The present invention comprises a segment seal 1 in which a pair of seal rings 10A, 10B are attached, in a state in which rotation is prevented, between one side end part 20 of a housing 2 and a support member 40 attached to the housing 2, whereby an annular gap between the housing 2 and a rotating shaft 3 is sealed, wherein protruding parts 32A, 32B are formed disposed so as not to be able to rotate in relation to the housing 2 or the support member 40, the protruding parts 32A, 32B engaging with the pair of seal rings 10A, 10B, and preventing the rotation of the pair of seal rings 10A, 10B, and at least one of the protruding parts 32A, 32B comprises a rotation-preventing member 30 that can engage only with one of the pair of seal rings 10A, 10B.
(FR) L'invention concerne un joint de segment avec lequel il est possible d'empêcher une fixation incorrecte d'une paire de bagues d'étanchéité dans un joint de segment en tandem. La présente invention comprend un joint de segment (1) dans lequel une paire de bagues d'étanchéité (10A, 10B) sont fixées, dans un état dans lequel la rotation est empêchée, entre une partie d'extrémité latérale (20) d'un boîtier (2) et un élément de support (40) fixé au boîtier (2), moyennant quoi un espace annulaire entre le boîtier (2) et un arbre rotatif (3) est scellé, des parties en saillie (32A, 32B) étant formées disposées de manière à ne pas pouvoir tourner par rapport au boîtier (2) ou à l'élément de support (40), les parties en saillie (32A, 32B) venant en prise avec la paire de bagues d'étanchéité (10A, 10B) et empêchant la rotation de la paire de bagues d'étanchéité (10A, 10B) et au moins l'une des parties saillantes (32A, 32B) comprenant un élément de prévention de rotation (30) qui peut venir en prise uniquement avec l'une de la paire de bagues d'étanchéité (10A, 10B).
(JA) タンデム型のセグメントシールにおける一対のシールリングの取付け間違いを防止することができるセグメントシールを提供する。 ハウジング2の一側端部20と、該ハウジング2に取付けられる支持部材40との間に一対のシールリング10A,10Bが回転を防止された状態で取付けられることにより、ハウジング2と回転軸3との間の環状隙間をシールするセグメントシール1であって、ハウジング2、或いは、支持部材40に対し回転不能に設置され、一対のシールリング10A,10Bと嵌合する凸部32A,32Bが形成され、該一対のシールリング10A,10Bの回転を防止するとともに、該凸部32A,32Bのうち、少なくともひとつは該一対のシールリング10A,10Bのどちらか一方とのみ嵌合可能な回転防止部材30を備える。
