Abstract
Description
Die vorliegende Erfindung betrifft ein Axiallager für eine Welle eines Abgasturboladers gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem einen, mit einem derartigen Axiallager ausgestatteten Abgasturbolader.The The present invention relates to a thrust bearing for a Shaft of an exhaust gas turbocharger according to the preamble of claim 1. The invention also relates to a equipped with such a thrust bearing exhaust gas turbocharger.
Im modernen Kraftfahrzeugbau werden zur Leistungssteigerung vermehrt Ladeeinrichtungen, so genannte Abgasturbolader, eingesetzt, welche eine, ein Turbinenrad und ein Verdichterrad tragende Welle aufweisen. Aufgrund der sehr hohen Umdrehungszahlen der Welle, muss diese sowohl in Radialrichtung als auch in Axialrichtung gelagert sein. Hierzu werden üblicherweise so genannte hydrodynamische Axiallager verwendet, wobei durch eine schnelle Rotation einer Lageranlaufscheibe Schmierstoff, dass heißt insbesondere Öl, an einer Keilfläche zwischen dem Axiallager und der Lageranlaufscheibe verdrängt wird. Durch die Verdrängung baut sich dabei ein Öldruck zwischen dem Axiallager und der Lageranlaufscheibe auf, der eine den äußeren Kräften entgegenwirkende axiale Kraft erzeugt. Nachteilig bei derartigen Axiallagern ist, dass eine Ölführung im Axiallager relativ langsam erfolgt, so dass das zur Schmierung des Axiallagers vorhandene Öl relativ lange im Axiallager verbleibt und aufgrund der hohen Umdrehungszahlen der Welle Gefahr läuft zu überhitzen.in the modern motor vehicle construction are increased to increase performance Charging devices, so-called exhaust gas turbocharger, used, which a, a turbine wheel and a compressor wheel bearing shaft. Due to the very high number of revolutions of the shaft, this must be both be stored in the radial direction and in the axial direction. These are usually so-called hydrodynamic thrust bearings used, whereby by a rapid rotation of a bearing washer lubricant, that is especially oil, on a wedge surface between the Thrust bearing and the bearing thrust washer is displaced. By the displacement builds up an oil pressure between the thrust bearing and the bearing washer on, the one outer Forces counteracting axial force generated. A disadvantage of Such thrust bearings is that an oil guide in the thrust bearing is relatively slow, so that the lubrication the axial bearing existing oil relatively long in thrust bearing remains and due to the high number of revolutions of the shaft danger is overheating.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, für ein Axiallager der gattungsgemäßen Art, eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, welche sich insbesondere durch eine verbesserte Lagerfunktion auszeichnet.The The present invention addresses the problem of for a thrust bearing of the generic Art, an improved or at least another embodiment specify which is characterized in particular by an improved storage function.
Dieses Problem wird erfindungsgemäß durch die Gegenstände der unabhängigen Ansprüche gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the objects of the independent claims. advantageous Embodiments are the subject of the dependent Claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, an einer Axiallagerscheibe eines Axiallagers für eine Welle eines Abgasturboladers radial verlaufende Ölzuführ- und Ölabführkanäle vorzusehen, wobei die Ölzuführkanäle zwischen Keilflächen angeordnet sind und die Keilflächen mit Öl versorgen, während die Ölabführkanäle benachbart zu den Ölzuführkanälen angeordnet und nach radial innen abgeschlossen sind. Bei einem Betrieb des Axiallagers strömt somit Öl über die Ölzuführkanäle auf die Keilflächen und bewirkt dort durch den Aufbau eines Öldrucks die eigentliche Lagerung, wobei im weiteren Verlauf das Öl über Rastflächen direkt in die Ölabführkanäle geleitet und somit schnell abgeführt werden kann. Im Vergleich zu herkömmlichen Axiallagern benötigt das erfindungsgemäße Axiallager einen weitaus geringeren Öldurchsatz bei gleicher Lagerfähigkeit. Würde ein im Vergleich zu konventionellen Axiallagern gleicher Öldurchsatz herrschen, so wäre die Lagerwirkung deutlich verbessert. Zudem sind zumindest die Ölzuführkanäle, die Ölabführkanäle und die Keilflächen als Negativkonturen in sich gegenüberliegende Flächen der im Wesentlichen kreiszylindrischen Axiallagerscheibe eingebracht, wodurch eine fertigungstechnisch einfache und dadurch kostengünstige Herstellung der erfindungsgemäßen Axiallagerscheibe möglich ist. Von besonderem Vorteil ist jedoch, dass unerwünschte Bypassströme, welche einen hohen Schmierstoffdurchsatz erfordern, mittels der erfindungsgemäßen Axiallagerscheibe vermieden werden können.The Invention is based on the general idea, on a thrust washer a thrust bearing for a shaft of an exhaust gas turbocharger radial oil supply and oil discharge channels to provide, wherein the oil supply channels are arranged between wedge surfaces and the wedge surfaces provide oil while the oil drainage channels arranged adjacent to the oil supply channels and are completed radially inward. During operation of the Thrust bearing thus flows oil through the oil supply channels on the wedge surfaces and causes there by the construction of an oil pressure the actual storage, whereby in the further course the oil over Detent surfaces directly into the oil drainage channels directed and thus can be dissipated quickly. Compared to conventional thrust bearings requires the invention Thrust bearing a much lower oil throughput at the same Storability. Would be one compared to conventional ones Thrust bearings equal oil flow prevail, it would be the storage effect significantly improved. In addition, at least the oil supply channels, the Ölabführkanäle and the wedge surfaces as negative contours in opposing surfaces the substantially circular cylindrical thrust bearing disc introduced, whereby a production technology simple and therefore cost-effective Production of the axial bearing disk according to the invention is possible. Of particular advantage, however, is that undesirable Bypass flows, which require a high lubricant throughput, by means of the axial bearing washer according to the invention can be avoided.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist in Umfangsrichtung zwischen jeweils einer Keilfläche und einem benachbarten radialen Ölabführkanal eine Rastfläche vorgesehen, die bezüglich der Keilfläche als Positivkontur ausgebildet ist. Das vom Ölzuführkanal über die Keilfläche auf die Rastfläche transportierte Öl kann dort die Schmierung bewirken, bis es aufgrund von Fliehkräften bzw. Mitnahmekräfte in den dazu benachbarten Ölabführkanal abgeführt wird. Derartige Rastflächen bewirken dabei ein schnelles Abfließen des zur Schmierung verwendeten Öls bzw. Schmierstoffes, wodurch die Schmierstoff-/Ölkühlung für das Axiallager verbessert wird.at an advantageous embodiment of the invention Solution, is in the circumferential direction between each of a wedge surface and a neighboring radial Ölabführkanal provided a locking surface, with respect to the Wedge surface is formed as a positive contour. The from the oil supply channel over the wedge surface on the catch surface transported oil can cause lubrication there, due to centrifugal forces or driving forces in the adjacent Ölabführkanal is dissipated. Such locking surfaces effect doing a quick drainage of the oil used for lubrication or lubricant, whereby the lubricant / oil cooling is improved for the thrust bearing.
Bei einer weiteren vorteilhaften Ausführungsform der erfindungsgemäßen Lösung, ist ein die Keilflächen radial umgebender Ölsammelkanal als Negativkontur in die sich gegenüberliegenden Flächen der Axiallagerscheibe eingebracht. Das Einbringen des Ölsammelkanals in die Fläche erfolgt dabei gleichzeitig mit dem Einbringen des Ölzuführkanals, des Ölabführkanals und der Keilflächen, vorzugsweise durch spanende Bearbeitung, Prägen oder mittels Metallpulverspritzgussverfahren (MIM). Durch derartige Herstellungsverfahren, lässt sich die erfindungsgemäße Axiallagerscheibe fertigungstechnisch einfach, geometrisch äußerst exakt und kostengünstig herstellen, wobei insbesondere aufwendige Nacharbeiten, bspw. zum Herstellen von einzelnen Kanalstrukturen, entfallen können.In a further advantageous embodiment of the solution according to the invention, an oil collecting channel radially surrounding the wedge surfaces is introduced as a negative contour into the opposing surfaces of the axial bearing disk. The introduction of the oil collection channel in the surface takes place simultaneously with the introduction of the Ölzuführkanals, the Ölabführkanals and the wedge surfaces, preferably by machining, stamping or by means of metal powder injection molding process (MIM). By such manufacturing method, the thrust washer according to the invention can be manufactured easily, geometrically extremely accurate and inexpensive to produce, in particular, expensive rework, for example. For the production of individual NEN channel structures can be omitted.
