Description

Nahtlose metallische Faltenbälge mit ringförmig in sich geschlossenen Falten sind schon seit längerer Zeit bekannt. Diese an sich sehr dünnwandigen Federrohre können nur für verhältnismäßig geringe Drücke Verwendung finden, da bei zu hohem äußerem oder innerem Überdruck die Außen- bzw. Innenflächen flach gedrückt werden, wodurch der Faltenbalg seine guten Federungseigenschaften verliert. Seamless metallic bellows with ring-shaped, self-contained folds are nice known for a long time. These spring tubes, which are very thin-walled, can only be used for Relatively low pressures are used, because if the external or internal pressure is too high Overpressure the outer or inner surfaces are pressed flat, whereby the bellows loses its good suspension properties.

Um derartige leicht federnde FaltenbälgeTo such slightly resilient bellows

auch für höhere Drücke ohne Einbuße der Elastizität nutzbar zu machen, hat man schon früher elastische oder feste Drahtringe in die Falten eingelegt. Das Einbringen derartiger Einlagen war aber umständlich und schwierig, und man half sich so, daß die festen Ringe als Spreizringe, ähnlich wie Kolbenringe, oder als geteilte Ringe in die Faltenbälge eingelegt wurden.It is already possible to use them for higher pressures without losing elasticity previously elastic or solid wire rings were inserted into the folds. The introduction of such But deposits was awkward and difficult, and you helped yourself so that the solid rings inserted into the bellows as expanding rings, similar to piston rings, or as split rings became.

Gegenstand der Erfindung ist nun ein Faltenbalg mit vollständig ringförmig in sich geschlossenen Profilringen, welche während der Verformung des glatten Rohres zum Faltenbalg gleichzeitig mit in die Falten eingewalzt und dabei weiterprofiliert werden. Es handelt sich also hier nicht um ein nachträgliches Einlegen von Verstärkungsringen in die Falten des fertiggeformten Metallbalges, sondem um Verstärkungsringe, welche in die am meisten beanspruchten Teile des Balges während der Verformung desselben fest eingewalzt und mitprofiliert werden. Hierdurch entstehen doppelwandige Außen- bzw. Innenwulste, während die dazwischenliegenden Stegteile des Balges einwandig verbleiben.The invention now relates to a bellows with a completely closed ring Profile rings, which during the deformation of the smooth tube to the bellows be rolled into the folds at the same time and further profiled in the process. It deals So it is not a question of subsequently inserting reinforcing rings into the folds of the finished metal bellows, special to reinforce rings, which in the Most of the stressed parts of the bellows are firmly rolled in during the deformation of the same and be profiled. This creates double-walled outer and inner beads, while the intermediate web parts of the bellows remain single-walled.

Die Zeichnung veranschaulicht zwei Ausführungsbeispiele des Erfindungsgedankens im Längsschnitt. Abb. ι zeigt den Faltenbalg ο mit in die Außenfalten eingewalzten Profilringen b im entspannten Zustand, geeignet für Außendruckbeanspruchung des Balges. Abb. 2 stellt den gleichen Faltenbalg in gepreßtem Zustand dar. Abb. 3 und 4 stellen den Faltenbalg α für höheren Innendruck dar, bei welchem die Profilringe· b' analog in die Falten eingewalzt sind.The drawing illustrates two exemplary embodiments of the inventive concept in longitudinal section. Fig. Ι shows the bellows ο with profile rings b rolled into the outer folds in the relaxed state, suitable for external pressure loading of the bellows. Fig. 2 shows the same bellows in the pressed state. Figs. 3 and 4 show the bellows α for higher internal pressure, in which the profile rings · b ' are rolled into the folds analogously.

Bei gleicher Außen- und Innenbelastung des Balges können die Verstärkungsringe auch beidseitig eingewalzt werden.With the same external and internal load on the bellows, the reinforcement rings can also be rolled in on both sides.

Zweckmäßig werden die Verstärkungsringe b und b' aus stärkerem und härterem Material bestehen als der Faltenbalg a. Die Formgebung des Profils kann naturgemäß den einzelnen Bedarfsfällen entsprechend angepaßt werden.The reinforcing rings b and b ' are expediently made of stronger and harder material than the bellows a. The shape of the profile can of course be adapted to the individual requirements.

Es ist ohne weiteres ersichtlich, daß derartige Faltenbälge durch die Verstärkungs- ringe weit höheren Drücken ausgesetzt werden können, ohne eine Deformation der FaI-ten befürchten zu müssen. Die Profilierung der Einwalzringe erfolgt derart, daß die gute Elastizität des Balges hierdurch nicht beeinträchtigt wird.It is readily apparent that such bellows are formed by the reinforcement rings Far higher pressures can be exposed without deformation of the folds to fear. The profiling of the roll-in rings is carried out in such a way that the good This does not affect the elasticity of the bellows.
