Abstract

The invention provides a slide bearing for crank shafts of internal combustion engines, in particular, engines of automative vehicles. To achieve a defined lubricating film between slide bearing and crank shaft at manufacturing costs reduced compared to the state-of-the-art bearings, and to attain a precise axial guidance of the crank shaft, a dual-conical formation (3) is provided in the area of the radial slide face (2). Advantageously, the dual-conical bearing layer is applied to a steel beam which, in its turn, for taking up the axial forces, is held by means of lateral flanges (6) on the engine block and on the bearing cap of the engine.

Description

Die Erfindung bezieht sich auf ein Radial-Axial-Gleitlager für Kurbelwellen von Verbrennungsmotoren.The invention relates to a radial-axial plain bearing for crankshafts of internal combustion engines.

Zur axialen Kraftaufnahme bei Kurbelwellen werden bislang Bundlager eingesetzt. Dabei sind die Reibungsverhältnisse an den Bunden nicht definierbar. Bestenfalls wird Mischreibung erreicht. Ein dynamischer Schmierfilm kann prinzipbedingt nicht aufgebaut werden. Eine exakte axiale Führung der Kurbelwelle ist nur bedingt erreichbar. Es wurden bereits Versuche mit formschlüssigen Verbindungen der Bunde mit der Lagerschale unternommen, welche jedoch zu keinen befriedigenden Ergebnissen führten.So far, axial force absorption in crankshafts Coil bearings used. The friction conditions are on the bundles cannot be defined. At best it becomes mixed friction reached. A dynamic lubricating film can in principle cannot be built up. Exact axial guidance of the The crankshaft can only be reached to a limited extent. Have already been Experiments with positive connections of the bundles with the Bearing shell undertaken, but none satisfactory results.

Aufgabe der Erfindung ist es, ein Gleitlager für Kurbelwellen zu schaffen, welches unter Vermeidung dieser Nachteile sich durch ein definiertes Schmierverhalten, geringe Herstellungskosten und eine exakte axiale Führung der Kurbelwelle auszeichnet.The object of the invention is a plain bearing for crankshafts to create which, while avoiding these disadvantages due to a defined lubrication behavior, low Manufacturing costs and an exact axial guidance of the Excellent crankshaft.

Diese Aufgabe wird nach der Erfindung i. w. dadurch gelöst, daß das Gleitlager im Bereich der radialen Gleitfläche doppeltkonisch ausgebildet ist.This object is i. w. solved by that the plain bearing in the area of the radial sliding surface is double conical.

Durch die doppeltkonische Ausbildung der Gleitfläche ist erreicht, daß Radialkräfte und ebenso Axialkräfte aufgenommen werden. Bei dem erfindungsgemäßen Gleitlager liegen definierte Schmierfilmverhältnisse vor. Die hierfür erforderliche Anpassung der Kurbelwelle an die doppelkonische Ausbildung des Gleitlagers läßt sich problemlos erreichen, bspw. durch Drehräumen oder Schleifen. Im Falle, daß alternativ zu einem Bundlager Anlaufscheiben vorgesehen sind, können diese durch den Einsatz des erfindungsgemäßen Gleitlagers entfallen.Due to the double-conical design of the sliding surface achieved that radial forces and axial forces are absorbed will. In the slide bearing according to the invention defined lubrication film ratios. The one for this  necessary adaptation of the crankshaft to the double conical Formation of the plain bearing can be easily achieved For example, by turning or grinding. In case that thrust washers are provided as an alternative to a flange bearing, can by using the invention Bearings do not apply.

In einer besonderen Ausführungsform der Erfindung ist die doppelkonische Lagerschicht auf einem Stahlträger aufgebracht, welcher seinerseits mittels seitlichen Bunden zum Aufnehmen der Axialkräfte am Motorblock und Lagerdeckel des Motors gehalten ist.In a particular embodiment of the invention double-conical bearing layer on a steel beam applied, which in turn by means of side bands for absorbing the axial forces on the engine block and bearing cover the engine is held.

Weitere Ziele, Vorteile, Merkmale und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles an Hand der Zeichnung. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger sinnvoller Kombination den Gegenstand der vorliegenden Erfindung, auch unabhängig von ihrer Zusammenfassung in den Ansprüchen oder deren Rückbeziehung.Further goals, advantages, features and possible applications of the present invention result from the following Description of an embodiment using the Drawing. All of them are described and / or illustrated illustrated features for themselves or in any more meaningful Combining the subject of the present invention, too regardless of their summary in the claims or their dependency.

Gemäß der Figur weist das erfindungsgemäße Radial-Axial- Gleitlager 1 für die Kurbelwelle 4 eines Motors im Bereich der Gleitfläche 2 eine doppelkonische Ausbildung 3 auf, welche bspw. durch einen entsprechenden Bohrvorgang erreicht werden kann. Die doppelkonische Lagerschicht 3 ist auf einem Stahlträger 5 aufgegossen, welcher sich mit seitlichen Bunden 6 am Motorblock 7 abstützt und hierdurch die auftretenden Axialkräfte auf den Motorblock 7 ableitet. Neben einem definierten Schmierfilm wird hierdurch eine exakte axiale Führung der Kurbelwelle erreicht.According to the figure, the radial-axial sliding bearing 1 according to the invention for the crankshaft 4 of an engine in the region of the sliding surface 2 has a double-conical design 3 , which can be achieved, for example, by a corresponding drilling process. The biconical bearing layer 3 is poured onto a steel beam 5 which is supported with side collars 6 on the engine block 7, and thereby the axial forces derived on the engine block. 7 In addition to a defined lubrication film, this ensures exact axial guidance of the crankshaft.

Bezüglich des Lagermaterials können alle gebräuchlichen Werkstoffe eingesetzt werden.With regard to the storage material, all common ones can be used Materials are used.
