Wälzlagerung mit SchwingungsdämpfungRolling bearing with vibration damping

Die vorliegende Neuerung betrifft eine Wälzlagerung von zwei zueinander drehbaren und konzentrisch ineinander angeordneten Teilen, deren einander zugewandte Mantelflächen einen mit Dämpfungsmittel, insbesondere Öl, befüllten, ringförmigen Dämpfungsspalt begrenzen, wobei diese Mantelflächen Laufflächen für Wälzkörper bilden.The present innovation relates to a rolling bearing of two parts that can rotate relative to one another and are arranged concentrically within one another, the facing outer surfaces of which delimit an annular damping gap filled with a damping agent, in particular oil, whereby these outer surfaces form running surfaces for rolling elements.

Eine derartige Wälzlagerung ist beispielsweise durch die CH-B-311 338 bekanntgeworden. Der Dämpfungsspalt wird von der Mantelfläche einer Welle, bzw. eines auf die Welle aufgesetzten rotationssymmetrischen Teiles und einer umhüllenden Gehäusebohrung begrenzt. Als Wälzkörper werden Kugeln eingesetzt, die entweder an den Mantelflächen der Welle und der Gehäusebohrung oder an Mantelflächen von ineinander angeordneten Ringen abwälzen. Bei allen offenbarten Ausführungsbeispielen ist die Bildung des Dämpfungsspaltes deshalb aufwendig, weil entweder ein separates, auf die Welle aufzusetzendes Teil benötigt wird, oder weil der Gehäusebohrungs- und der Wellendurchmesser aufeinander abgestimmt werden müssen.Such a rolling bearing has become known, for example, from CH-B-311 338. The damping gap is limited by the outer surface of a shaft or a rotationally symmetrical part placed on the shaft and an enclosing housing bore. Balls are used as rolling elements, which roll either on the outer surfaces of the shaft and the housing bore or on the outer surfaces of rings arranged inside one another. In all of the embodiments disclosed, the formation of the damping gap is complex because either a separate part is required to be placed on the shaft or because the housing bore and shaft diameters must be matched to one another.

Aufgabe der vorliegenden Neuerung ist es daher, eine derartige Wälzlagerung dahingehend weiterzubilden, daß die Bildung und die Begrenzung des Dämpfungsspaltes auf technisch und wirtschaftliche einfache Art und Weise möglich ist, wobei weiterhin eine Wälzlagerung mit hoher radialer Belastbarkeit gewährleistet sein soll.The aim of this innovation is therefore to further develop such a rolling bearing so that the formation and limitation of the damping gap is possible in a technically and economically simple manner, while still ensuring a rolling bearing with a high radial load capacity.

Neuerungsgemäß wird diese Aufgabe dadurch gelöst, daß die Wälzkörper Zylinder sind, und daß die Teile je durch einen Wälzlagerring gebildet sind. Bei den Wälzlagerringen kann es sich um glattzylindrische Ringe handeln oder auch um Ringe, an deren einander zugewandten Mantelflä-According to the innovation, this task is solved by the rolling elements being cylinders and the parts each being formed by a rolling bearing ring. The rolling bearing rings can be smooth cylindrical rings or rings with

2560-11-DE 22560-11-EN 2

chen einander gegenüberliegende radiale Absätze vorgesehen sind, so daß die radial weiter voneinander beabstandeten Mantelflächen die Wälzflächen bilden und die radial näher beieinander liegenden Mantelflächen den Dämpfungsspalt begrenzen. Derartige Ringe können sowohl auf spangebende als auch auf spanlose Art und Weise hergestellt werden. Radial steps are provided opposite one another so that the radially further apart shell surfaces form the rolling surfaces and the radially closer together shell surfaces limit the damping gap. Such rings can be manufactured both by cutting and non-cutting methods.

Gemäß Anspruch 2 ist es zweckmäßig, daß der Dämpfungsspalt zu seinen beiden Stirnseiten hin mittels zwischen den Wälzlagerringen angeordneten Dichtringen abgedichtet ist. Die Dichtringe verhindern dabei das Austreten des Dämpfungsmittels.According to claim 2, it is expedient that the damping gap is sealed on both its front sides by means of sealing rings arranged between the roller bearing rings. The sealing rings prevent the damping agent from escaping.

Nachstehend wird die Neuerung anhand von zwei in zwei Figuren dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:
15The innovation is explained in more detail below using two exemplary embodiments shown in two figures. They show:

Figur 2 eine neuerungsgemäße Wälzlagerung im LängsschnittFigure 2 shows a longitudinal section of a rolling bearing according to the innovation

Die Figur 1 zeigt im Längsschnitt eine neuerungsgemäße Wälzlagerung; diese besteht aus zwei konzentrisch ineinander angeordneten Ringen 1, 2, an deren einander zugewandten Mantelflächen Wälzflächen 3, 4 für Nadeln 5 ausgebildet sind. Die Nadeln 5 sind doppelreihig in einem Käfig 6 geführt. Axial benachbart zu den Wälzflächen 3, 4 sind die Durchmesser der einander zugewandten Mantelflächen der Ringe 1, 2 derart aufeinander abgestimmt, daß ein Dämpfungsspalt 7 gebildet und durch diese Mantelflächen begrenzt ist. An seinen stirnseitigen Enden weist der äußere Ring 1 je einen Durchmesservergrößerung 8 auf, in der ein Dichtring 9 angeordnet ist. Diese Dichtringe 9 verhindern, daß in dem Dämpfungsspalt 7 vorgesehenes Öl 10 nach außerhalb des Lagers abströmen kann. Der Außenring 1 weist eine Querbohrung 11 auf, die nach außen abschließbar ist, und durch die das Öl 10 in den Dämpfungsspalt 7 gelangt. Figure 1 shows a longitudinal section of a roller bearing according to the innovation; this consists of two concentrically arranged rings 1, 2, on whose mutually facing surfaces rolling surfaces 3, 4 for needles 5 are formed. The needles 5 are guided in a double row in a cage 6. Axially adjacent to the rolling surfaces 3, 4, the diameters of the mutually facing surfaces of the rings 1, 2 are coordinated with one another in such a way that a damping gap 7 is formed and is delimited by these surfaces. At its front ends, the outer ring 1 has a diameter enlargement 8 in which a sealing ring 9 is arranged. These sealing rings 9 prevent oil 10 provided in the damping gap 7 from flowing out of the bearing. The outer ring 1 has a transverse bore 11 which can be closed off from the outside and through which the oil 10 reaches the damping gap 7.

Die in Figur 2 dargestellte neuerungsgemäße Wälzlagerung unterscheidet sich von der aus der Figur 1 lediglich dadurch, daß ein weiterer Dichtring 12 zwischen den beiden Dichtringen 9 angeordnet ist, der denThe new rolling bearing shown in Figure 2 differs from that in Figure 1 only in that a further sealing ring 12 is arranged between the two sealing rings 9, which
