Title (EN) FLUID COUPLING COMPRISING SHAFT SEALING DEVICE FOR PREVENTING LEAKAGE OF LUBRICATING OIL
(FR) COUPLAGE FLUIDIQUE COMPRENANT UN DISPOSITIF D'ÉTANCHÉITÉ D'ARBRE POUR ÉVITER LA FUITE DU HUILE LUBRIFIANTE
(JA) 潤滑油の漏洩を防止する軸封装置を有する流体継手
Abstract:
(EN) The present invention relates to a shaft sealing device for a fluid coupling. A fluid coupling is provided with: a casing (8) for accommodating an impeller (1) and a runner (2); a drive shaft (11) having the impeller (1) fixed thereto; an output shaft (12) that has the runner (2) fixed thereto and that extends through the casing (8); and an output shaft sealing device (65) that prevents the leakage of lubricating oil from a gap between the casing (8) and the output shaft (12). The output shaft sealing device comprises: a shaft seal (68) surrounding the outer circumferential surface of the output shaft; an output shaft sealing cover (66) that covers the shaft seal; an ejector (60); and an output shaft oil return pipe (67) that extends from the output shaft sealing cover to the ejector. Lubricating oil supplied to at least one bearing rotatably supporting each of the drive shaft and the output shaft is used by the ejector as a driving fluid.
(FR) La présente invention concerne un dispositif d'étanchéité d'arbre pour un couplage fluidique. Un couplage fluidique est pourvu de : un boîtier (8) pour recevoir une roue (1) et une lisse (2); un arbre d'entraînement (11) sur lequel la roue (1) est fixée; un arbre de sortie (12) qui comporte la lisse (2) fixée à celui-ci et qui s'étend à travers le boîtier (8); et un dispositif d'étanchéité d'arbre de sortie (65) qui évite la fuite d'huile lubrifiante depuis un espacement entre le boîtier (8) et l'arbre de sortie (12). Le dispositif d'étanchéité d'arbre de sortie comprend : un joint d'étanchéité d'arbre (68) entourant la surface circonférentielle externe de l'arbre de sortie; un couvercle d'étanchéité d'arbre de sortie (66) qui recouvre le joint d'étanchéité d'arbre; un éjecteur (60); et un tuyau de retour d'huile d'arbre de sortie (67) qui s'étend du couvercle d'étanchéité d'arbre de sortie à l'éjecteur. L'huile lubrifiante distribuée à au moins un palier soutenant de façon rotative chacun de l'arbre d'entraînement et l'arbre de sortie est utilisé par l'éjecteur en tant que fluide d'entraînement.
(JA) 本発明は、流体継手の軸封装置に関するものである。 流体継手は、インペラ(1)およびランナ(2)を収容するケーシング(8)と、インペラ(1)が固定された駆動軸(11)と、ランナ(2)が固定され、ケーシング(8)を貫通して延びる出力軸(12)と、ケーシング(8)と出力軸(12)との間の隙間から潤滑油の漏洩を防止する出力軸軸封装置(65)を備える。出力軸軸封装置は、出力軸の外周面を囲む軸シール(68)と、軸シールを覆う出力軸軸封カバー(66)と、エゼクター(60)と、出力軸軸封カバーからエゼクターまで延びる出力軸油戻り配管(67)を有する。エゼクターは、駆動軸および出力軸を回転可能にそれぞれ支持する軸受の少なくとも一つに供給される潤滑油を駆動流体として用いる。
