Abstract
Description
Die Erfindung betrifft einen Rollenlagerkäfig und eine Rollenlagerung, wie sie insbesondere zum drehbaren Lager einer Kurbelwelle und einer Pleuelstange an der Kurbelwelle eingesetzt werden.The The invention relates to a roller bearing cage and a roller bearing, as in particular to the rotatable bearing of a crankshaft and a Connecting rod to be used on the crankshaft.
Insbesondere bei der Verwendung an Kurbelwellen sollen Rollenlagerungen und auch deren Rollenlagerkäfige dahingehend Vorteile aufweisen, dass sie leichtgewichtig sind, eine hohe Belastungskapazität, eine hohe Festigkeit und eine hohe Leistungsfähigkeit bei hohen Umdrehungen aufweisen und darüber hinaus in der Lage sind, unter anspruchsvollen Schmierungsbedingungen verwendet werden zu können.Especially when used on crankshafts roller bearings and also their roller bearing cages have advantages that they are lightweight, a high load capacity, high strength and high performance at high revolutions and above in addition are capable under demanding lubrication conditions to be used.
Eine Aufgabe der vorliegenden Erfindung ist es daher, eine Verbesserung bei einem Rollenlagerkäfig und einer Rollenlagerung, insbesondere bei Verwendung an einer Kurbelwelle zu schaffen.A Object of the present invention is therefore an improvement at a roller bearing cage and a roller bearing, in particular when used on a crankshaft to accomplish.
Die Aufgabe wird durch die Gegenstände der Ansprüche 1 und 11 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The Task is through the objects the claims 1 and 11 solved. Advantageous embodiments are described in the subclaims.
Anspruch 1 betrifft einen Rollenlagerkäfig mit wenigstens einem ringartigen Seitenelement, von dessen wenigstens einer Stirnseite zum Bilden von Aufnahmen für Rollen Stegelemente abzweigen, wobei in wenigstens einem radial äußeren und/oder inneren Oberflächenbereich der Stegelemente, der einer Führungsfläche für den Käfig zum Gegenüberliegen vorgesehen ist, wenigstens in einem Bereich hin zum Seitenelement derart gestaltet ist, dass bei Betrachtung des Stegelementquerschnitts die den Rollenmänteln zugewandten Seitenflächen des Stegelements scharfkantig in geradlinige, von den Seitenflächen hin zur Stegmitte mit an Höhe zunehmende Bereiche übergehen, und die geradlinigen Bereiche in Stegmitte in eine Verrundung übergehen.claim 1 relates to a roller bearing cage with at least one annular side member, at least one of which an end face to form shots for rolling branch off web elements, wherein in at least one radially outer and / or inner surface area the web elements, the guide surface for the cage for Face is provided, at least in an area towards the side element is designed such that when viewing the web element cross-section the roll coats facing side surfaces of the bridge element sharp-edged in rectilinear, from the side surfaces to the bridge center with at height pass over increasing areas, and merge the rectilinear areas at the middle of the bridge into a rounding.
Durch die besagte Ausbildung wird mit besonderem Vorteil ein Aufschwimmen des Käfigs erleichtert, so dass sich ähnlich wie bei einem Gleitlager gute Gleiteigenschaften des Käfigs gegenüber seiner Lagerumgebung ergeben.By The said training will be a particular advantage of the cage relieved, so that is similar as with a sliding bearing good sliding properties of the cage over his Storage environment revealed.
Anspruch 11 betrifft eine Rollenlagerung mit einem Rollenlagerkäfig, der längs geteilt, wenigstens zwei sektorartige Käfigteile ausbildend gestaltet ist, wobei die Lagerung derart gestaltet ist, dass der Käfig an entsprechenden Führungsflächen für den Käfig radial innen und außen geführt ist.claim 11 relates to a roller bearing with a roller bearing cage, the split longitudinally, at least two sector-like cage parts is designed forming, the storage is designed in such a way that the cage at corresponding guide surfaces for the cage radially inside and outside guided is.
Durch diese sozusagen gemischte gleichzeitige Innen- und Außenführung des Käfigs wird mit besonderem Vorteil erreicht, dass beispielsweise bei Einsatz an einer Kurbelwelle bei Betrieb durch die charakteristische Bewegung besagter Lagerstelle ungünstige Krafteinwirkungen auf den Käfig verhindert werden.By This mixed, so to speak simultaneous inner and outer guide of cage is achieved with particular advantage that, for example, when used on a crankshaft when operating by the characteristic movement said deposit unfavorable Force effects on the cage be prevented.
