Description
Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Labyrinthdichtungen, das zum Zwecke der billigen Herstellung der Dichtung darin besteht, daß nach Befestigung von Dichtungsstreifen in den Nuten einer ebenen Metallplatte letztere zylindrisch gebogen und gegebenenfalls noch mit einem Tragkörper metallisch verbunden wird.The invention relates to a method for producing labyrinth seals, that for the purpose of cheap production of the seal is that after fastening of sealing strips in the grooves of a flat metal plate, the latter cylindrical is bent and optionally connected to a support body in a metallic manner.
Die Zeichnung zeigt in Abb. 1 bis 13 die Ausführung des Verfahrens.The drawing shows in Fig. 1 to 13 the Execution of the procedure.
Abb. ι zeigt eine Platte α aus Metall, in die, entsprechend Abb. 2, Nuten b eingearbeitet werden, deren Abstand gleich dem der Labyrinthkämme ist. In diese werden Metallstreifen c eingesetzt, und zwar derart, daß die am Fuße des Streifens c gemäß Abb. 3 und 4 einseitig angebrachten Rillen i bei je zwei benachbarten Streifen einander zugekehrt sind. Staucht man nun das zwischen zwei Streifen c befindliche Material einer solchen Platte a (Abb. 5), z. B. durch Walzen (Abb. 6), so wird eine einwandfreie Verbindung von Platte und Streifen hergestellt, die durch nachherige Verlötung verbessert werden kann. Unter Umständen wird auch eine Verlötung für die Verbindung allein genügen.Fig. Ι shows a plate α made of metal, in which, according to Fig. 2, grooves b are incorporated, the distance between which is equal to that of the labyrinth crests. Metal strips c are inserted into these in such a way that the grooves i made on one side at the foot of the strip c according to FIGS. 3 and 4 face each other in two adjacent strips. If one now compresses the material of such a plate a located between two strips c (Fig. 5), e.g. B. by rolling (Fig. 6), a perfect connection of plate and strip is made, which can be improved by subsequent soldering. Under certain circumstances, soldering alone will suffice for the connection.
Soll aus einem derartigen Element eine zylindrische Dichtung, deren Kämme nach außen ragen, hergestellt werden, so kann dies durch entsprechendes Rundwalzen der Platte und Verlötung bzw. Verschweißung der Stoßstelle geschehen. Dieser Zylinder kann dann ent- , weder unmittelbar oder unter Zwischenschal- , tung einer Buchse e (Abb. 7 und 8) auf die Welle aufgebracht werden.If a cylindrical seal, the crests of which protrude outwards, is to be produced from such an element, this can be done by appropriate rolling of the plate and soldering or welding of the joint. This cylinder can then be attached to the shaft either directly or with the interposition of a bushing e (Figs. 7 and 8).
Soll die Dichtung in einem Hohlkörper Verwendung finden, so wird die Platte α hohlgewalzt (Abb. 9), so daß Hohlringe oder Hohlringteile (Abb. 10) entstehen, die in den Hohlkörper eingesetzt werden (Abb. 11). Überragende Teile werden nachträglich entfernt. Abb. 13 zeigt die Dichtung in einem Hohlzylinder.If the seal is to be used in a hollow body, the plate α is rolled hollow (Fig. 9), so that hollow rings or hollow ring parts (Fig. 10) are created which are inserted into the hollow body (Fig. 11). Outstanding parts are subsequently removed. Fig. 13 shows the seal in a hollow cylinder.
Dichtungen mit schräg stehenden Kämmen (Abb. 13) können aus solchen mit gerade stehenden Kämmen durch Drücken und nachheriges Überdrehen bzw. Überschleifen hergestellt werden.Seals with inclined combs (Fig. 13) can be made from those with straight standing combs by pressing and then turning or grinding over will.
Dichtungen größerer Breite können durch Aneinanderfügen mehrerer Zylinder ohne gegenseitige nachfolgende metallische Verbindung hergestellt werden.Larger width seals can be made by joining several cylinders without mutual subsequent metallic connection can be established.
