Title (EN) CAGE FOR A ROLLER BEARING FOR ROTATIONALLY MOUNTING A HIGH-SPEED SHAFT
(FR) CAGE POUR PALIER À ROULEMENT DESTINÉ AU MONTAGE ROTATIF D'UN ARBRE À HAUT RÉGIME
(DE) KÄFIG FÜR EIN WÄLZKÖRPERLAGER ZUR DREHBAREN LAGERUNG EINER HOCHDREHENDEN WELLE
Abstract:
(EN) The invention relates to a cage (1) for a roller bearing (2) for rotationally mounting a high-speed shaft, in particular a shaft for a turbocharger, comprising two cage rings (3) and a plurality of connecting elements (4) and cavities (5) for the rolling bodies, wherein the connecting elements (4) extend axially between the cage rings (3), and the cavities (5) are arranged tangentially between the connecting elements (4). According to the invention, the cage (1) is made from a metallic material and is essentially formed according to a shaping method, wherein two tangentially adjacent ends of the cage (1) are interconnected in a material fit. The invention also relates to a roller bearing (2) comprising the above-mentioned cage.
(FR) L'invention concerne une cage (1) pour un palier à roulement (2) destiné au montage rotatif d'un arbre à haut régime, en particulier d'un arbre pour un turbocompresseur, laquelle cage comprend deux anneaux de cage (3), ainsi qu'une pluralité d'éléments jointifs (4) et d'alvéoles (5) destinées à des éléments roulants, les éléments jointifs (4) s'étendant axialement entre les anneaux de cage (3) et les alvéoles (5) étant agencées tangentiellement entre les éléments jointifs (4). Selon l'invention, la cage (1) est constituée d'un matériau métallique et est réalisée par une technique de formage, deux extrémités de la cage (1) adjacentes tangentiellement étant assemblées par liaison de matière. L'invention concerne en outre un palier à roulement (2) pourvu de la cage susmentionnée.
(DE) Die Erfindung betrifft einen Käfig (1) für ein Wälzkörperlager (2) zur drehbaren Lagerung einer hochdrehenden Welle, insbesondere einer Welle für einen Turbolader, umfassend zwei Käfigringe (3) sowie eine Vielzahl von Stegen (4) und Taschen (5) für Wälzkörper, wobei sich die Stege (4) axial zwischen den Käfigringen (3) erstrecken, und wobei die Taschen (5) tangential zwischen den Stegen (4) angeordnet sind. Erfindungsgemäß besteht der Käfig (1) aus einem metallischen Werkstoff und ist im Wesentlichen umformtechnisch ausgebildet, wobei zwei tangential benachbarte En^den des Käfigs (1) stoffschlüssig miteinander verbunden sind. Ferner betrifft die Erfindung auch ein Wälzkörperlager (2) mit dem zuvor genannten Käfig.
