Description

Mehrstufige, axial beaufschlagte Gleichdruck- oder Überdruckturbine Zusatz zur Patentanmeldung L 37127 I a / 14 c (Auslegeschrift 1138 071) Die Erfindung betrifft eine mehrstufige Axialturbine, bei der die Leitschaufeln der einzelnen Stufen nur an ihrem radial äußeren Ende, und zwar von Ringen getragen werden, die, auch die benachbarten Laufschaufelkränze mit geringem Spiel umgebend, mit hammerkopfförmig profiliertem Flansch in Gehäuseringnuten von Hammerkopfprofil radial gleiten können und in Segmente geteilt sind, die durch Federn radial einwärts an die Nutwand angedrückt werden, und bei der das Gehäuse ein nicht in Achsebene geteiltes, sogenanntes Topfgehäuse ist und die hammerkopfförmig profilierten Nuten von zentrisch-wärmebeweglich ins Gehäuse eingesetzten, nicht in Achsebene geteilten, scheibenförmigen Zentrierringen und von diese auf Abstand haltenden, ebenfalls nicht in Achsebene geteiltenAbstandsringen gebildet werden, nach Patentanmeldung L 37127 I a/ 14c.Multi-stage, axially loaded constant pressure or overpressure turbine Addendum to patent application L 37127 I a / 14 c (Auslegeschrift 1138 071) The invention relates to a multi-stage axial turbine in which the guide vanes of the individual stages are only supported at their radially outer end, namely by rings , which, also surrounding the adjacent rotor blade rings with little play, can slide radially with a hammer-head-shaped profiled flange in casing ring grooves of hammer-head profile and are divided into segments that are pressed radially inward against the groove wall by springs, and in which the casing is not divided in the axial plane , so-called cup-shaped housing and the hammer-head-shaped profiled grooves are formed by centric-heat-movable, disc-shaped centering rings inserted into the housing that are not divided in the axial plane and by spacer rings that keep them at a distance, also not divided in the axial plane, according to patent application L 37127 I a / 14c.

Die Zeichnung und die Beschreibung der Hauptpatentanmeldung zeigen die Leitschaufeln deckbandlos.The drawing and description of the main patent application show the guide vanes without shroud.

Es kann nun manchmal wünschenswert sein, die Schaufeln mit Deckband zu versehen, und zwar auch mit solchen, welche Dichtkämme besitzen. Solche sind an sich bekannt.It can now sometimes be desirable to have the blades shrouded to be provided, including those that have sealing combs. Such are known per se.

Die Erfindung sieht daher vor, die Leitschaufeln und die Laufschaufeln mit Deckbändern zu versehen, die an ihren freien Umfangsflächen Dichtkämme aufweisen.The invention therefore provides the guide vanes and the rotor blades to be provided with cover bands which have sealing ridges on their free peripheral surfaces.

Es können in ebenfalls bekannter Weise die Dichtkämme in Dichtnuten ragen, die über den Umfang des Turbinenläufers und den Innenumfang der Leitschaufelträgersegmente verlaufen.It can also be used in a known manner, the sealing combs in sealing grooves protrude over the circumference of the turbine rotor and the inner circumference of the guide vane support segments get lost.

In der Zeichnung sind die Leitschaufelträgersegmente mit 1, der Läufer mit 6, die Leitschaufeln mit 14 und die Laufschaufeln mit 64, die Deckbänder mit 17 bzw. 67, die Dichtkämme mit 18 bzw. 68 und die Dichtnuten mit 19 bzw. 69 bezeichnet.In the drawing, the guide vane segments are marked with 1, the rotor with 6, the guide vanes with 14 and the rotor blades with 64, the shrouds with 17 and 67, the sealing combs 18 and 68 and the sealing grooves 19 and 69, respectively.
