Title (EN) ROTARY LEADTHROUGH AND CRANKSHAFT ASSEMBLY
(FR) PASSAGE TOURNANT ET ENSEMBLE VILEBREQUIN
(DE) Drehdurchführung und Kurbelwellenanordnung
Abstract:
(EN) The invention relates to a rotary leadthrough, comprising a stationary component (2), a rotating component (3), exactly one bearing (4), which supports the rotating bearing (3) on the stationary component (2), and a seal assembly (5) having a carbon ring (50) and an elastomer ring (51), wherein the carbon ring (50) is arranged between the rotating component (3) and the stationary component (2) such that the carbon ring can move in the axial direction (X-X), and wherein the seal assembly (5) has a first sealing region (14) on the elastomer ring and a second sealing region (15) on the carbon ring.
(FR) L'invention concerne un passage tournant, comportant un élément fixe (2), un élément rotatif (3), un seul support (4), lequel sert au support de l'élément rotatif (3) sur l'élément fixe (2), et un ensemble d'étanchéité (5) comprenant une bague en carbone (50) et une bague en élastomère (51), la bague en carbone (50) étant agencée entre l'élément rotatif (3) et l'élément fixe (2) de manière à pouvoir se déplacer dans la direction axiale (X-X), et l'ensemble d'étanchéité (5) présentant une première zone d'étanchéité (14) sur la bague en élastomère et une deuxième zone d'étanchéité (15) sur la bague en carbone.
(DE) Die Erfindung betrifft eine Drehdurchführung, umfassend ein stationäres Bauteil (2), ein rotierendes Bauteil (3), genau ein Lager (4), welches das rotierende Bauteil (3) am stationären Bauteil (2) lagert, und eine Dichtungsanordnung (5) mit einem Kohlenstoffring (50) und einem Elastomerring (51), wobei der Kohlenstoffring (50) in Axialrichtung (X-X) beweglich zwischen dem rotierenden Bauteil (3) und dem stationären Bauteil (2) angeordnet ist, und wobei die Dichtungsanordnung (5) einen ersten Abdichtbereich (14) am Elastomerring und einen zweiten Abdichtbereich (15) am Kohlenstoffring aufweist.
