KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Labyrinthdichtung für Gas- oder Dampfturbinen, bei welchen Blechringe benutzt werden, und hat zum Zweck, eine dauerhafte und zuverlässige Befestigung der dünnen Dichtungsringe zu ermöglichen. The invention relates to a labyrinth seal for gas or steam turbines, in which Sheet metal rings are used, and has the purpose of a permanent and reliable fastening to allow the thin sealing rings.
Die Erfindung besteht darin, daß die dünnen, flanschenartigen Dichtungsränder durch Vermittelung eines besonderen Befestigungsdrahtes in eine Nut des Tragorganes eingelegt und die Flanschen dieser Nut gegeneinander gebogen sind und dadurch den Draht umfassen. Der Draht und die Flanschen der Nut sind dabei derart ausgeführt, daß die Dichtungsränder in achsialer Richtung unterstützt werden.The invention is that the thin, flange-like sealing edges through Mediation of a special fastening wire inserted into a groove in the support member and the flanges of this groove are bent towards one another and thereby enclose the wire. The wire and the flanges of the groove are designed in such a way that the sealing edges support in the axial direction will.
Ein Ausführungsbeispiel der Erfindung ist auf der Zeichnung veranschaulicht.An embodiment of the invention is illustrated in the drawing.
Fig. ι zeigt die einzelnen Teile vor und Fig. 2 nach der Befestigung.Fig. Ι shows the individual parts before and Fig. 2 after attachment.
Der Dichtungsring α besitzt die beiden Flanschen b und eine Ringnut e. Das U-förmig gebogene Dichtungsblech c ist zweckmäßig aus Nickel oder Nickelstahl hergestellt. d ist ein zweckmäßig aus Eisen oder Stahl bestehender Draht, der bei der Ausführungsform nach Fig. 1 einen etwa T-förmigen Querschnitt besitzt.The sealing ring α has the two flanges b and an annular groove e. The U-shaped bent sealing plate c is expediently made of nickel or nickel steel. d is a wire suitably made of iron or steel which, in the embodiment according to FIG. 1, has an approximately T-shaped cross section.
Bei der Herstellung wird zuerst das Dichtungsblech c in die Nut e und hierauf der Draht d in die Nut des Dichtungsbleches eingelegt. Die beiden Flanschen b werden dann gegeneinander gebogen, und das Ganze erhält dadurch die aus Fig. 2 ersichtliche Form. Die Ränder des Bleches c sind hier gemäß der Erfindung unterstützt, und zwar bis zum Rande des Dichtungsringes a. During production, the sealing plate c is first inserted into the groove e and then the wire d is inserted into the groove of the sealing plate. The two flanges b are then bent towards one another, and the whole is thereby given the shape shown in FIG. The edges of the sheet c are supported here according to the invention, up to the edge of the sealing ring a.
