Abstract
Vorgeschlagen ist eine Lageranordnung, umfassend eine Welle (1) mit einem Lagerzapfen (2, 3) und einen auf dessen Umfang abwälzenden Nadelkranz mit einem geschlitzten oder mehrteiligen Käfig (13, 13', 13''), der mit radial zu den Nadeln (22) überstehenden Anlaufflächen (15, 16; 15', 16'; 15'', 16'') axial an der Welle geführt ist. Die Anlaufflächen sollen axial innerhalb der Längserstreckung der Nadeln angeordnet sein und mit radial einwärtigem Überstand den Käfig an den Nutwänden (17, 18) einer den Lagerzapfen durchsetzenden Umfangsnut (12) axial führen.Proposed is a bearing arrangement, comprising a shaft (1) with a bearing journal (2, 3) and a roller bearing on its circumference with a slotted or multi-part cage (13, 13 ', 13' '), which with radial to the needles ( 22) projecting thrust surfaces (15, 16, 15 ', 16', 15 '', 16 '') is guided axially on the shaft. The contact surfaces should be arranged axially within the longitudinal extent of the needles and axially guide the cage with radially inward projection on the groove walls (17, 18) of the bearing pin passing through a circumferential groove (12).
Description
Die Erfindung betrifft eine Lageranordnung, umfassend eine Welle mit einem Lagerzapfen und einen auf dessen Umfang abwälzenden Nadelkranz mit einem geschlitzten oder mehrteiligen Käfig, der mit radial zu den Nadeln überstehenden Anlaufflächen axial an der Welle geführt ist.The invention relates to a bearing assembly, comprising a shaft with a bearing journal and a rolling over the circumference of the needle ring with a slotted or multi-part cage, which is axially guided with radially projecting to the needles stop surfaces on the shaft.
Eine derartige Lageranordnung ist aus der
Aus der
Der Erfindung liegt die Aufgabe zu Grunde, eine konstruktive Alternative einer Lageranordnung der eingangs genannten Art anzugeben.The invention is based on the object to provide a constructive alternative of a bearing assembly of the type mentioned.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die Anlaufflächen axial innerhalb der Längserstreckung der Nadeln angeordnet sind und mit radial einwärtigem Überstand den Käfig an den Nutwänden einer den Lagerzapfen durchsetzenden Umfangsnut axial führen. Die erfindungsgemäße Axialführung eignet sich besonders für solche Lageranordnungen, bei denen die wellenseitigen Führungsflächen bislang nur teilumfänglich seitlich neben dem Lagerzapfen ausgebildet werden konnten und aus Funktionsgründen aufwändig bearbeitet werden mussten.According to the invention, this object is achieved in that the abutment surfaces are arranged axially within the longitudinal extent of the needles and with radially inward supernatant axially guide the cage on the groove walls of a bearing pin passing through the circumferential groove. The axial guide according to the invention is particularly suitable for those bearing arrangements in which the shaft-side guide surfaces could hitherto only be formed partially laterally next to the bearing journal and had to be laboriously worked for functional reasons.
Weitere Merkmale und Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung und aus den Zeichnungen, in denen die erfindungsgemäße Lageranordnung anhand von Ausführungsbeispielen dargestellt ist. Es zeigen jeweils in perspektivischer Darstellung:Further features and embodiments of the invention will become apparent from the following description and from the drawings, in which the bearing assembly according to the invention is illustrated by means of embodiments.
