Description

irLagerbüchse'= Die Erfindung betrifft eine Lagerbüchse, insbesondere für Wälzlager, die in radialer Richtung elastisch nachgiebig ausgebildet ist.irLagerbüchse '= The invention relates to a bearing sleeve, in particular for roller bearings which are designed to be elastically flexible in the radial direction.

Für viele Zwecke, wie z. B. für die Lagerung eines im überkritischen ' Bereich laufenden Gasturbinenrotors, wird eine elastische Nachgiebigkeit der Lager in radialer Richtung gefordert. Derartige Lagerungen, z. B. unter Zwischenschaltung von Gummielementen oder Blattfedern, sind an sich bekannt. Die Lösung dieser Aufgabe gestaltet sich jedoch dann schwierig, wenn bei Elastizität in radialer Richtung starre Fixierung in axialer Richtung und ein möglichst geringer Raumbedarf der Lagerung gefordert wird.For many purposes, such as B. for the storage of an in the supercritical 'The running gas turbine rotor area, will have an elastic resilience of the bearings Required in the radial direction. Such bearings, e.g. B. with interposition of rubber elements or leaf springs are known per se. The solution to this problem However, it turns out to be difficult when elastic in the radial direction rigid fixation in the axial direction and the least possible space requirement for storage is required.

Zur Lösung dieser Aufgabe wird deshalb eine Lagerbüchse, insbesondere für Wälzlager, die in radialer Richtung elastisch nachgiebig ausgebildet ist, vorgeschlagen, bei der erfindungsgemäß ein das Lager aufnehmender Innenring mit einem Außenring durch dazwischen angeordnete, dünnwandige, sich in axialer Richtung erstreckende Körper verbunden ist. -Nach einer vorteilhaften Ausführungsform der Erfindung werden als elastische Körper dünnwandige Rohre, insbesondere Stahlrohre, verwendet, die z. B. kreisförmigen oder etwa kreuzförmigen Querschnitt aufweisen können.To solve this problem, a bearing bush, in particular proposed for rolling bearings which are designed to be elastically flexible in the radial direction, in the case of the invention, an inner ring receiving the bearing with an outer ring by thin-walled ones arranged in between and extending in the axial direction Body is connected. -According to an advantageous embodiment of the invention thin-walled pipes, in particular steel pipes, are used as elastic bodies, the z. B. may have circular or approximately cruciform cross-section.

Es kann jedoch auch vorteilhaft sein, als elastische Körper wellenförmige, dünnwandige Bänder, insbesondere Stahlbänder, zu verwenden. Die elastischen Körper werden dabei vorzugsweise durch Löten mit dem Innen- und Außenring verbunden.However, it can also be advantageous to use wave-shaped, thin-walled tapes, in particular steel tapes, to be used. The elastic body are preferably connected to the inner and outer rings by soldering.

Der Gegenstand der Erfindung soll im folgenden anhand eines in der beiliegenden Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden. In der Zeichnung zeigen Fig. 1 eine Vorderansicht einer erfindungsgemäßen Lagerbüchse, und Fig. 2 einen Schnitt nach der Linie II-II der Fig. 1. rungsring 3 gehalten. Zwischen dem Innenring 2 und dem Außenring 4 der Lagerbüchse sind elastische Körper in Form von dünnwandigen Rohren 5, die im dargestellten Beispiel kreisförmigen oder etwa kreuzförmigen Querschnitt aufweisen, oder wellenförmigen dünnen Bändern 6 angeordnet. Die Bänder 6 können dabei z. B. die in Fig. 1 angedeuteten Formen aufweisen.The subject of the invention will be explained in more detail below with reference to an embodiment shown in the accompanying drawing. In the drawing, FIG. 1 shows a front view of a bearing bush according to the invention, and FIG. 2 shows a section along the line II-II in FIG. 1. ring ring 3 held. Between the inner ring 2 and the outer ring 4 of the bearing bushing, elastic bodies in the form of thin-walled tubes 5, which in the example shown have a circular or approximately cruciform cross-section, or wavy thin strips 6 are arranged. The bands 6 can, for. B. have the shapes indicated in FIG.

Die Verbindung der elastischen Körper 5 bzw. 6 mit dem Innenring 2 und dem Außenring 4 der Lagerbüchse erfolgt vorteilhaft durch Löten. Wenn als elastische Körper Rohre 5 verwendet werden, kann die Federkennzahl der 4nordnung dann besonders genau eingehalten werden, wenn die Rohre 5 nicht kreisförmigen Querschnitt aufweisen, da dann die Breite des zu verlötenden Teiles geringeren Schwankungen unterliegt.The connection of the elastic bodies 5 or 6 to the inner ring 2 and the outer ring 4 of the bearing bush is advantageously carried out by soldering. if are used as the elastic body tubes 5, the spring number of the 4 order are then adhered to particularly precisely if the tubes 5 are not of circular cross-section have, since then the width of the part to be soldered less fluctuations subject.
