Abstract: front page image
(EN) A mechanical seal device is provided with: a rotating ring (7) which is affixed to a rotating shaft (300); a stationary ring (4) which is in slidable contact with the rotating ring (7) to form an annular seal surface (S); a bellows (5) which supports the stationary ring (4) so that the stationary ring (4) presses the rotating ring (7); a spring (6) which presses the stationary ring (4) against the rotating ring (7), and a seal cover (2) which is mounted to a housing (200), supports the bellows (5) so that the outer peripheral surface of the bellows (5) is located inside (A) the housing (200) relative to the seal surface (S), and supports the spring (6) at a position outside (B) the housing (200) relative to the seal surface (S) and axially next to the bellows (5).
(FR) L'invention porte sur un dispositif d'étanchéité mécanique qui comprend : une bague rotative (7) qui est fixée à un arbre rotatif (300) ; une bague fixe (4) qui est en contact glissant avec la bague rotative (7) pour former une surface d'étanchéité annulaire (S) ; un soufflet (5) qui soutient la bague fixe (4) de telle sorte que la bague fixe (4) presse la bague rotative (7) ; un ressort (6) qui presse la bague fixe (4) contre la bague rotative (7), et un couvre-joint (2) qui est monté sur un carter (200), soutient le soufflet (5) de telle sorte que la surface périphérique extérieure du soufflet (5) est placée à l'intérieur (A) du carter (200) par rapport à la surface d'étanchéité (S), et soutient le ressort (6) dans une position à l'extérieur (B) du carter (200) par rapport à la surface d'étanchéité (S) et axialement près du soufflet (5).
(JA) 回転軸(300)に固定される回転環(7)と、回転環(7)に摺動自在に接触して環状のシール面(S)を形成する固定環(4)と、固定環(4)を回転環(7)に対して付勢するように支持するベローズ(5)と、固定環(4)を回転環(7)に対して付勢するスプリング(6)と、ハウジング(200)に取り付けられ、ベローズ(5)を、その外周面がシール面(S)に対してハウジング(200)の内部A側となるように支持するとともに、スプリング(6)を、シール面(S)に対してハウジング(200)の外部B側かつベローズ(5)に対して軸方向に並んだ位置で支持するシールカバー(2)と、を備える。
