Title
(DE) LAGERANORDNUNG MIT EINEM MEDIENGESCHMIERTEN LAGER
(EN) BEARING ARRANGEMENT HAVING A MEDIA-LUBRICATED BEARING
(FR) AGENCEMENT DE PALIER COMPORTANT UN PALIER LUBRIFIÉ
Abstract
(DE)
Die Erfindung betrifft eine Lageranordnung für ein mediengeschmiertes Lager (1), umfassend eine Welle (2), die um eine Drehachse (3) drehbar in einem Lagergehäuse gelagert ist, ein von einem Schmiermedium, insbesondere Wasser, durchströmtes Lager (1), mit dem die Welle (2) an dem Lagergehäuse gelagert ist, ein mit der Welle (2) drehfestes Förderelement (4), eine radial gerichtete Einlassöffnung (5) für das Schmiermedium, eine Auslassöffnung (6) für mit Partikeln befrachtetes Schmiermedium, und eine Zuführleitung (7) für das Schmiermedium zu dem Lager (7). Die Aufgabe, eine Lageranordnung für ein mediengeschmiertes Lager anzugeben, die einfach ausgestaltet und wartungsfreundlich ist, wird erfindungsgemäß dadurch gelöst, dass die Einlassöffnung (5) sich im Bereich einer Verzweigung (14) in eine zu der Auslassöffnung (6) führenden Auslassleitung (15) und in die Zuführleitung (7) teilt, dass die Auslassleitung (15) sich zu der Auslassöffnung (6) hin verjüngt, und dass in der Zuführleitung (7) angrenzend an die Verzweigung (14) ein Filterelement (16) angeordnet ist.
(EN)
The invention relates to a bearing arrangement for a media-lubricated bearing (1), comprising a shaft (2), which is supported in a bearing housing so as to be rotatable about a rotational axis (3), a bearing (1), through which a lubricating medium, in particular water, flows, by means of which bearing the shaft (2) is supported against the bearing housing, a conveying element (4) rotationally fixed to the shaft (2), a radially oriented inlet opening (5) for the lubricating medium, an outlet opening (6) for lubricating medium loaded with particles, and a supply line (7) for the lubricating medium to the bearing (7). The aim of specifying a bearing arrangement for a media-lubricated bearing that is simply designed and maintenance-friendly is achieved according to the invention in that the inlet opening (5) is divided in the area of a branching point (14) into an outlet line (15) leading to the outlet opening (6) and the supply line (7), in that the outlet line (15) is tapered toward the outlet opening (6), and in that in the supply line (7) a filter element (16) is arranged adjacent to the branching point (14).

L'invention concerne un agencement de palier destiné à un palier lubrifié (1) et comprenant un arbre (2) qui est monté pivotant autour d'un axe de pivotement (3) dans un logement de palier, un palier (1) parcouru par un lubrifiant, notamment de l'eau, et grâce auquel l'arbre (2) est monté sur le logement de palier, un élément de refoulement (4) solidaire en rotation avec l'arbre (2), une ouverture d'admission (5) orientée radialement pour le lubrifiant, une ouverture d'évacuation (6) pour le lubrifiant chargé en particules, et une conduite d'amenée (7) pour l'alimentation du palier (7) en lubrifiant. L'invention vise à proposer un agencement de palier destiné à un palier lubrifié qui soit configuré de manière simple et qui soit d'entretien facile. A cette fin, l'ouverture d'admission (5) se divise dans la zone d'un embranchement (14) en une conduite d'évacuation (15) menant à l'ouverture d'évacuation (6) et en la conduite d'amenée (7), la conduite d'évacuation (15) s'amincissant en direction de l'ouverture d'évacuation (6) et un élément filtrant (16) étant disposé dans la conduite d'amenée (7) à proximité de l'embranchement (14).
