Lager, insbesondere GelenkgleitlagerBearings, in particular articulated plain bearings
Die Neuerung bezieht sich auf Lager, insbesondere auf Gelenkgleitlager mjt einem außen balligen Innenring und einem entsprechend konkav gewölbten Außenring.The innovation relates to bearings, in particular to articulated plain bearings with an outer convex inner ring and a corresponding one concave outer ring.
Bekannte Gelenkgleitlager werden bisher durch spanende Bearbeitung aus rohrförmigem Ausgangsmaterial hergestellt. Die Praxis hat gezeigt, daß es trotz sorgfältigster Bearbeitung der Lagergleitflächen sehr schwierig ist, diese Flächen so zu formen, daß die Gleitflächen der Außenringe auf ihrer gesamten Breite gegen die Gleitflächen der Innenringe anliegen.Known articulated plain bearings are hitherto made by machining made from tubular starting material. Practice has shown that despite the most careful processing the bearing sliding surfaces is very difficult to shape these surfaces so that the sliding surfaces of the outer rings over their entire Width against the sliding surfaces of the inner rings.
Gemäß vorliegender Neuerung wird dieser Nachteil dadurch behoben, daß in mindestens einem Lagerring ei:, elastischer Hohlkörper angeordnet ist. Der Hohlraum des elastischen Körpers wird vorzugsweise mit einem flüssigen oder gasförmigen Medium oder mit einem elastischen Werkstoff, beispielsweise mit Schaumstoff gefüllt. Die gegen die Gleitfläche des anderen Lagerringes anliegende Fläche des elastischen Körpers wird vorzugsweise mit einem Werkstoff mit guten Gleiteigenschaften, beispielsweise mit Polytetrafluoräthylen beschichtet.According to the present innovation, this disadvantage is eliminated in that in at least one bearing ring ei :, elastic hollow body is arranged. The cavity of the elastic body is preferably filled with a liquid or gaseous medium or filled with an elastic material, for example with foam. The one against the sliding surface of the other bearing ring adjacent surface of the elastic body is preferably made of a material with good sliding properties, for example coated with polytetrafluoroethylene.
Durch den elastischen Hohlkörper werden eventuelle Formungenauigkeiten der Lagergleitfläche ausgeglichen. Ferner kann die Lagerluft den jeweiligen Erfordernissen entsprechend geregelt werden,Any shape inaccuracies are eliminated by the elastic hollow body the bearing sliding surface balanced. Furthermore, the internal clearance can be regulated according to the respective requirements,

und ausserdem sind die nach der Neuerung ausgebildeten Gelenkgleitlager wartungsfrei.and in addition, the articulated plain bearings designed according to the innovation maintenance free.
In der Zeichnung ist die Neuerung an einigen Ausführungsbeispielen veranschaulicht, und zwar zeigen die Figuren 1 bis 3 Teillängsschnitte durch dr«i verschiedene Ausführungsformen von Gelenkgleitlagern.The drawing shows the innovation in some exemplary embodiments illustrated, and that Figures 1 to 3 show partial longitudinal sections through three different embodiments of spherical plain bearings.
Gemäss Fig. 1 ist der aussenfballige Innenring Il des Lagers in üblicher Weise durch spanende Bearbeitung, der Aussenring 2 dagegen durch spanlose Verformung aus Bandmaterial hergestellt. In dem Hohlraum des Aussenringes 2 ist ein elastischer Hohlkörper 3 angeordnet, der mit einem flüssigen oder gasförmigen Medium oder mit einem elastischen Werkstoff gefüllt ist und mit seiner gesamten Innenfläche gegen die ballige Gleitfläche des Innenringes 1 anliegt. Auf diese Innenfläche des Hohlkörpers 3 ist eine Schicht 4- aus einem Werkstoff mit guten Gleiteigenschaften, beispielsweise aus Polytetrafluorathylen aufgebracht, so daß die zwischen Innen- und Aussenring auftretende Reibung nur gering ist.According to FIG. 1, the outer crowned inner ring II of the bearing is in Usually by machining, the outer ring 2, on the other hand, is produced from strip material by non-cutting deformation. In the cavity of the outer ring 2, an elastic hollow body 3 is arranged, which with a liquid or gaseous Medium or filled with an elastic material and with its entire inner surface against the convex sliding surface of the Inner ring 1 rests. On this inner surface of the hollow body 3 is a layer 4- made of a material with good sliding properties, For example, made of polytetrafluoroethylene applied, so that the friction occurring between the inner and outer ring is only slight.
Bei der Ausführungsform nach Fig. 2 ist im Innenring 4- eine Aussparung vorgesehen, in der ein Hohlkörper 3 aus elastischem Werkstoff angeordnet ist, dessen gegen die Gleitfläche des Aussenringes 5 anliegende Fläche eine Schicht 4 aus Polytetrafluorathylen od. dgl. aufweist.In the embodiment according to FIG. 2, there is a recess in the inner ring 4- provided, in which a hollow body 3 made of elastic material is arranged, which against the sliding surface of the Outer ring 5 adjacent surface a layer 4 made of polytetrafluoroethylene or the like.
Die Ausführungsform nach Fig. 3 entspricht im wesentlichen der Ausführungsform nach Fig. 1, jedoch ist hier die Schicht 4· aus Polytetrafluorathylen od. dgl. auf der balligen Gleitfläche des Innenringes 1 vorgesehen, gegen die die Innenfläche des elastischen Hohlkörpers 2 anliegt.The embodiment of FIG. 3 corresponds essentially to that Embodiment according to FIG. 1, but here the layer 4 is made of polytetrafluoroethylene or the like on the spherical sliding surface of the Inner ring 1 is provided against which the inner surface of the elastic hollow body 2 rests.
Naturgemäss sind die Ausführungsmöglichkeiten der Neuerung durch die dargestellten Ausführungsbeispiele nicht erschöpft. So ist es beispielsweise auch möglich, die Ringe von Wälzlagern gemäss vorliegender Neuerung mit elastischen Hohlkörpern auszustatten.Naturally, the implementation options of the innovation are through the illustrated embodiments are not exhausted. So it is also possible, for example, according to the rings of rolling bearings to equip the present innovation with elastic hollow bodies.
