Abstract
Description
Die vorliegende Erfindung betrifft ein Axiallager, insbesondere für eine Welle eines Abgasturboladers, mit einem im Wesentlichen scheibenförmigen Lagerkörper, gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a thrust bearing, in particular for a shaft of an exhaust gas turbocharger, with a substantially disc-shaped bearing body, according to the preamble of claim 1.
Aus
der
Derartige, wie aus dem Stand der Technik bekannte, Axiallager, werden üblicherweise auch bei Abgasturboladern eingesetzt, wobei die dabei eingesetzten Axiallager üblicherweise aus einer Kupferlegierung, insbesondere aus Bronze, hergestellt sind. Diese Axiallager bestehen dabei im Wesentlichen aus folgenden Funktionselementen: Keilflächen, axiale Dichtflächen, Ölverteilerkanäle, Ölzuführungsbohrungen, Ölabflussbohrung und Durchgangsbohrung für die Welle. Durch die Integration mehrer, insbesondere sekundärer, Funktionen in einem Dichtbereich des Axiallager, ist dessen radiale Ausdehnung im Vergleich zur primären Funktion, nämlich der Aufnahme der Axialkräfte durch die Keilflächen, sehr groß. Dadurch ist insgesamt auch ein großer Stoffeinsatz von teurem Buntmetall erforderlich, der jedoch zwingend nur für die Keilflächen bzw. die Keilflächen bildenden Lagerelemente erforderlich ist.such, As known from the prior art, thrust bearings are usually also used in exhaust gas turbochargers, wherein the case used Thrust bearing usually made of a copper alloy, in particular made of bronze. These thrust bearings exist in the Essentially of the following functional elements: wedge surfaces, axial sealing surfaces, oil distribution channels, oil supply holes, oil drainage hole and through hole for the shaft. Through the integration several, especially secondary, functions in a sealing area of the thrust bearing, is its radial extent compared to the primary Function, namely the absorption of the axial forces through the wedge surfaces, very large. This is Overall, a large substance use of expensive non-ferrous metal necessary, but only for the wedge surfaces or the wedge surfaces forming bearing elements required is.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Axiallager der gattungsgemäßen Art, eine verbesserte Ausführungsform anzugeben, welche insbesondere wirtschaftlich herstellbar ist.The The present invention addresses the problem of for a thrust bearing of the generic Art to provide an improved embodiment which is particularly economical to produce.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, ein Axiallager mehrteilig auszubilden und dadurch teure Werkstoffe, wie bspw. Kupferlegierungen, auf lediglich diejenigen Bereiche des Axiallagers zu beschränken, in welchem sie unbedingt erforderlich sind. Die anderen Bereiche können daher aus kostengünstigeren Materialien, bspw. aus einer Stahllegierung oder Kunststoff, aufgebaut werden. Durch die mehrteilige Ausbildung des erfindungsgemäßen Axiallagers, kann dieses somit individueller und insbesondere kostengünstiger aufgebaut werden.The Invention is based on the general idea, a thrust bearing in several parts train and thereby expensive materials, such as. Copper alloys, to restrict to only those areas of the thrust bearing, in which they are absolutely necessary. The other areas can therefore be made from less expensive materials, For example, from a steel alloy or plastic, are constructed. By the multi-part design of the invention Axiallagers, this can thus individual and in particular cost-effective being constructed.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, besteht ein Lagerkörper des Axiallagers aus einer inneren, die Lagerelemente tragenden Lagerscheibe und einem, diese umgebenden Lagerring. Das Axiallager ist in diesem Fall ebenfalls mehrteilig aufgebaut, wobei für den Lagerring bspw. eine kostengünstige Stahllegierung oder ein Kunststoffmaterial verwendet werden kann, während die Lagerscheibe oder bspw. lediglich die Lagerelemente der Lagerscheibe aus einer teuren Kupferlegierung hergestellt sind. Die Aufteilung des Lagerkörpers in die innen liegende Lagerscheibe und den diese Lagerscheibe umgebende Lagerring stellt damit lediglich eine mögliche Ausführungsform des mehrteiligen Aufbaus des Axiallagers dar.at an advantageous embodiment of the invention Solution, there is a bearing body of the thrust bearing from an inner, the bearing elements bearing bearing disc and one, this surrounding bearing ring. The thrust bearing is in this Case also constructed in several parts, for the bearing ring bspw. an inexpensive steel alloy or a plastic material can be used while the bearing disc or bspw. only the bearing elements of the bearing disk made of an expensive copper alloy are made. The division of the bearing body in the inner bearing disc and surrounding this bearing disc Bearing ring thus provides only one possible embodiment the multi-part construction of the thrust bearing.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung, sind die Lagerelemente separat hergestellt und mit dem Lagerkörper, welcher bspw. als Lagerscheibe ausgebildet sein kann, verbunden, insbesondere verklebt, verlötet oder verschweißt. In diesem Fall, müssen lediglich die Lagerelemente aus dem vergleichsweise teuren Material, bspw. der Kupferlegierung, hergestellt werden, währen der gesamte Lagerkörper aus einem kostengünstigen Material, bspw. aus einer Stahllegierung oder aus Kunststoff hergestellt werden kann. Die genannten Verbindungsverfahren hängen dabei selbstverständlich von dem verwendeten Material des Lagerkörpers ab.at a further advantageous embodiment of the invention Solution, the bearing elements are manufactured separately and with the bearing body, which, for example, designed as a bearing disc can be connected, in particular glued, soldered or welded. In this case, only need the bearing elements of the relatively expensive material, eg. the copper alloy, while the entire Bearing body made of a cost-effective material, For example, be made of a steel alloy or plastic can. Of course, the connection methods mentioned depend on this from the material used in the bearing body.
