Title
(DE) Gleitlagervorrichtung, Getriebevorrichtung mit einer Gleitlagervorrichtung und Gasturbinentriebwerk mit einer Gleitlagervorrichtung
Abstract
(DE)

Die Erfindung betrifft eine Gleitlagervorrichtung (50) mit einem Schmierfilm zwischen Gleitflächen (51, 52) und mit mindestens einem Partikeltransportkanal (60) in mindestens einer Gleitfläche (51, 52) der Gleitlagervorrichtung (50), wobei die Richtung des mindestens einen Partikeltransportkanals (60) • bei einer radialen Gleitlagervorrichtung (50) mindestens abschnittsweise einen Winkel (α) ungleich 90° zu einer Ebene senkrecht zur Rotationsrichtung (R) aufweist, • bei einer axialen Gleitlagervorrichtung (50) mindestens abschnittsweise einen Winkel (α) ungleich 0° zu einer zylindrischen Fläche um die Rotationrichtung (R) aufweist, und der mindestens eine Partikeltransportkanal (60) im Betrieb fluidisch in Kontakt mit mindestens einem Partikelreservoir (61a, 61b, 61c, 61d) steht und das der mindestens eine Partikeltransportkanal (60) durch das mindestens eine Partikelreservoir (61a, 61b, 61c, 61d) hindurchgeht und / oder darauf gerichtet ist.
