Abstract
(DE) 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 (a) ungleich 90° zu einer Ebene senkrecht zur Rotationsrichtung (R) aufweist, • · bei einer axialen Gleitlagervorrichtung (50) mindestens abschnittsweise einen Winkel (a) 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 (61 a, 61 b, 61 c, 61 d) steht und das der mindestens eine Partikeltransportkanal (60) durch das mindestens eine Partikelreservoir (61 a, 61 b, 61 c, 61 d) hindurchgeht und / oder darauf gerichtet ist.
(EN) The invention relates to a slide bearing device (50) comprising a lubrication film between sliding surfaces (51, 52) and comprising at least one particle transport channel (60) in at least one sliding surface (51, 52) of the slide bearing device (50), wherein the direction of the at least one particle transport channel (60) has • · an angle (a) not equaling 90° relative to a plane perpendicular to the rotational direction (R) at least in some sections in the case of a radial slide bearing device (50) and • · an angle (a) not equaling 0° relative to a cylindrical surface about the rotational direction (R) at least in some sections in the case of an axial slide bearing device (50), the at least one particle transport channel (60) fluidically contacts at least one particle reservoir (61 a, 61 b, 61 c, 61 d) during operation, and the at least one particle transport channel (60) passes through and/or faces the at least one particle reservoir (61 a, 61 b, 61 c, 61 d).
(FR) L'invention concerne un dispositif de palier à glissement (50) qui comprend un film lubrifiant entre les surfaces de glissement (51, 52) et au moins un canal de transport de particules (60) dans au moins une surface de glissement (51, 52) du dispositif de palier à glissement (50) ; la direction du ou des canaux de transport de particules (60) présentant un angle (a) non égal à 90° par rapport à un plan perpendiculaire à la direction de rotation (R) dans au moins certaines sections dans le cas d'un dispositif de palier à glissement radial (50), et un angle (a) non égal à 0° par rapport à une surface cylindrique autour de la direction de rotation (R) au moins dans certaines sections dans le cas d'un dispositif de palier à glissement axial (50) ; le ou les canaux de transport de particules (60) étant en contact fluidique avec au moins un réservoir de particules (61 a, 61 b, 61 c, 61 d) pendant le fonctionnement, et le ou les canaux de transport de particules (60) passant à travers et/ou faisant face à ou aux réservoirs de particules (61 a, 61 b, 61 c, 61 d).
