Description
Gleitlager Bei hoch belasteten Gleitlagern ist es bekannt, daß während des Betriebes der Lagerkörper, d. h. der Stützkörper für die Lagerschale und auch der Lagerzapfen der Welle, unter der Wirkung der Last geringe Durchbiegtmgen erfahren- können. Diese Durchhiegungen haben zur Folge, daß die der Lagerung dienende Stelle der Welle (Lagerzapfen) nicht mehr mit ihrer ganzen Fläche der Lagerschale anliegt. Es ist mithin für die Lagerung nur mehr ein Teil der eigentlich dafür vorgesehenen Auflagefläche wirksam. In der kleineren für die Lagerung wirksamen Fläche muß nun der ganze Lagerdruck aufgenommen werden, mit anderen Worten, die spezifische Belastung der Lagerschale an der erwähnten Stelle wird sehr hoch: Unter besonders ungünstigen Verhältnissen können sogar übermäßige Beanspruchungen auftreten, die zu einer Betriebsgefährdung durch Unbrauchbarwerden der Lagerschale infolge Überlastung führen.Plain bearings In highly loaded plain bearings, it is known that during the operation of the bearing bodies, d. H. the support body for the bearing shell and also the bearing journals of the shaft experience little deflection under the action of the load. can. These sags have the consequence that the location used for storage the shaft (bearing journal) no longer rests with its entire surface on the bearing shell. It is therefore only part of what is actually intended for storage Effective support surface. In the smaller area that is effective for storage must now the entire bearing pressure can be absorbed, in other words the specific load the bearing shell at the point mentioned is very high: under particularly unfavorable Conditions can even cause excessive stresses, which can endanger the operation cause the bearing shell to become unusable as a result of overloading.
Aufgabe der Erfindung ist es, ein Gleitlager für Wellen u. dgl. zu schaffen, bei -dem die geschilderten Mißstände vermieden sind und hei welchem durch eine besondere Gestaltun- des Lagers übermäßige Beanspruchungen nicht auftreten können.The object of the invention is to provide a plain bearing for shafts and the like create, in which the abuses described are avoided and by which means a special design and excessive loads do not occur can.
Dies wird erfindungsgemäß dadurch erreicht, daß der in Achsrichtung verlaufende Wendungsquerschnitt der Lagerschale oder Büchse, deren dem Stützkörper zugekehrte Flächen nur an einzelnen Teilen ihrer Längserstreckung auf dem Stützkörper aufliegen, «-obei sie zwischen diesen Stellen mit dem Stützkörper einen Hohlraum einschließen. 1>o-enförtnig ausgebildet ist. Dabei hat die bogenförmige Ausgestaltung den Sinn, daß mit zunehmender Belastung immer neue Flächen zum Tragen zugeschaltet werden, so daß das Lager um so gleichmäßiger trägt, je stärker es belastet ist. Es ist zwar eine Lagerschale für Wellen bekannt, die in einem Stützkörper eingesetzt ist, bei der die dem Stützkörper zugekehrte Fläche der Lagerschale nur an einzelnen Stellen ihrer Längserstreckung auf dem Stützkörper aufliegt und zwischen diesen Stellen mit dem Stützkörper einen Hohlraum einschließt. Diese Lagerschale trägt aber auf Grund besonderer Ausnehmungen zwischen den Enden oder zwischen der Mitte und den Enden unabhängig -on der Belastung stets mit den gleichen Flächen.This is achieved according to the invention in that the in the axial direction running turning cross-section of the bearing shell or sleeve, the supporting body facing surfaces only on individual parts of their longitudinal extent on the support body rest, «- with a cavity between these points with the supporting body lock in. 1> is designed o-enförtnig. It has the arcuate design the sense that as the load increases, new areas are always added to carry so that the bearing carries the more evenly, the more it is loaded. Although a bearing shell for shafts is known that is used in a support body is, in which the support body facing surface of the bearing shell only on individual Make their longitudinal extension rests on the support body and between them Place with the support body enclosing a cavity. This bearing shell carries but due to special recesses between the ends or between the middle and ends independently -on the load always with the same Surfaces.
In der beiliegenden Zeichnung ist ein Beispiel für die Gestaltung eines Lagers nach der Erfindung dargestellt.In the accompanying drawing is an example of the design a bearing according to the invention.
Gemäß der Abbildung weist die Lagerschale i, in ihrer Längsrichtung gesehen, eine. Wölbung auf, derart, daß ihre Stützfläc% ,:4 lediglich an den Enden auf der zylindrisch' ausgestalteten Auflagefläche 5 des Stützk, pers -2 aufliegt, in der Mitte jedoch einen-' ringen Abstand von dieser= hat, so daß von der Stützfläche 4 der Lagerschale und der Auflagefläche 5 des Stützkörpers ein Hohlraum begrenzt wird. Die Lauffläche 7 der Lagerschale i ist im gleichen Sinne wie die Stützfläche 4 gewölbt. so daß die Lagerschale nur in der Mitte ihrer Längserstreckung die zylindrische Lauffläche 8 der Welle 3 berührt. Wird das Lager belastet, so tritt eine Verformung der Lagerschale i ein, in der Weise, daß die Wölbung der Lauffläche 7 mit zunehmender Belastung immer flacher wird. wobei die Berührungsfläche zwischen der Lauffläche 7 der Schale i und der Lauffläche 8 der Welle 3 größer wird. Bei zunehmender Belastung des Lagers wird durch Formänderung der Lagerschale der zwischen ihr und dem Stützkörper eingeschlossene Hohlraum verkleinert, während durch zunehmende Anschmiegung der Lauffläche der Lagerschale an die Wellenoberfläche die wirksame Lagerflache mit zunehmender Belastung vergrößert wird.According to the figure, the bearing shell has i, in its longitudinal direction seen one. Curvature in such a way that their support surface%,: 4 only at the ends rests on the cylindrically designed support surface 5 of the support body, pers -2, in the middle, however, has a small distance from this =, so that from the support surface 4 of the bearing shell and the bearing surface 5 of the support body delimits a cavity will. The running surface 7 of the bearing shell i is in the same sense as the support surface 4 domed. so that the bearing shell is cylindrical only in the middle of its longitudinal extension Contact surface 8 of the shaft 3 touches. If the bearing is loaded, a deformation occurs the bearing shell i a, in such a way that the curvature of the running surface 7 with increasing Load is getting flatter. wherein the interface between the tread 7 of the shell i and the running surface 8 of the shaft 3 becomes larger. With increasing load of the bearing is by changing the shape of the bearing shell between it and the support body enclosed cavity is reduced in size, while by increasing nestling of the Running surface of the bearing shell on the shaft surface with the effective bearing surface increasing load is increased.
