Title (EN) PLAIN BEARING WITH FLOATING SINTERED BUSHING, AND PLANETARY STAGE COMPRISING SUCH A PLAIN BEARING
(FR) PALIER LISSE DOTÉ D'UNE DOUILLE FRITTÉE À MONTAGE FLOTTANT ET ÉTAGE PLANÉTAIRE COMPORTANT UN TEL PALIER LISSE

Abstract:
(EN) The invention relates to an assembly comprising a first bearing ring (107), a second bearing ring (105), a bushing (115), and a lubricant line (119, 121), the bushing (115) being arranged between the first bearing ring (107) and the second bearing ring (105) and being made of a sintered material. The bushing (115) is rotatable relative to the first bearing ring (107) and the second bearing ring (105). A first bearing gap runs between the first bearing ring (107) and the bushing (105), and a second bearing gap runs between the second bearing ring (105) and the bushing (115), with the lubricant line (119, 121) leading into the first bearing gap and/or into the second bearing gap.
(FR) L'invention concerne un dispositif comprenant une première bague de roulement (107), une deuxième bague de roulement (105), une douille (115) et un conduit de lubrification (119, 121) ; la douille (115) étant disposée entre la première bague de roulement (107) et la deuxième bague de roulement (105) et comportant un matériau fritté. La douille (115) peut tourner par rapport à la première bague de roulement (107) et à la deuxième bague de roulement (105). Un premier jeu de palier s'étend entre la première bague de roulement (107) et la douille (105) et un deuxième jeu de palier s'étend entre la deuxième bague de roulement (105) et la douille (115). Le conduit de lubrification (119, 121) débouche sur le premier jeu de palier et/ou le deuxième jeu de palier.
(DE) Die Erfindung betrifft eine Anordnung mit einem ersten Lagerring (107), einem zweiten Lagerring (105), einer Buchse (115) und einer Schmierstoffleitung (119, 121); wobei die Buchse (115) zwischen dem ersten Lagerring (107) und dem zweiten Lagerring (105) angeordnet ist und aus einem Sintermaterial besteht. Die Buchse (115) ist relativ zu dem ersten Lagerring (107) und dem zweiten Lagerring (105) verdrehbar; wobei zwischen dem ersten Lagerring (107) und der Buchse (105) ein erster Lagerspalt und zwischen dem zweiten Lagerring (105) und der Buchse (115) ein zweiter Lagerspalt verläuft; und wobei die Schmierstoffleitung (119, 121) in den ersten Lagerspalt und/oder in den zweiten Lagerspalt mündet.
