 druckes entfallen und das Einsetzen der Schaufeln wird wesentlich vereinfacht, ohne dass die Sicheriehti der Schaufelbefestigung verminidert würde. Die Beilagen y können entweder nach Fig. 5 mit vorstehenden   Kanten/' ausgebildet   sein, die sich   ohneweiteres   gegen die beim Pressen entstehenden Abrundungen der Schaufelkanten zwischen Seitenteil   b und Schaufelbodenlappen a

 Arbeitsmethoden dieselbe und in Fig. 8 dargestellt. 



   Fig. 18 stellt eine Befestigungsweise der Schaufel nach Fig. 13 dar, die von der nach Fig. 17 dadurch abweicht, dass die Vorsprünge an den   Nutwanrbnigen,   die in die entsprechenden Wellungen 
 EMI2.3 
   vorhanden   sind (Fig. 12 und 16). 



   Fig. 19 stellt   gegenüber   den anderen Figuren eine neue Anordnung der Ausführungsform der Schaufeln nach Fig. 2, 3 und 4 dar. die auch auf die anderen   Ausfülhrungsformen   der Schaufelstiele Anwendung finden kann und bei welcher der Schaufelboden mit der Oberkante der Nut nicht bündig, vielmehr zwischen dieser Oberkante und dem Schaufelboden ein Spielraum vor-   handen ist.   Auf diese   Weise ist es möglich,   bei durchgehender Zyliderwand bezw. Läuferwand   zwischen dem freien Ende der Leitschaufel   und der   Zylinderwand, bezw. zwischen dem freien   Ende der Leitschaufel und dem Läufer ein hinreichendes Spiel zu erzeugen, ohne dass es nötig

   PATENT-ANSPRÜCHE :
1. Laufrad für Dampfturbinen nach Patent Nr. 33246, jedoch so, dass die Schaufeln in Nuten des Laufrades eingelegt sind, dadurch gekenzneichnet, dass die Schaufeln in den Nuten des   Laufrades mittels der gegeneinander geneigten, ebenen oder   in der Richtung des Radius

 pressure is eliminated and the insertion of the blades is significantly simplified without reducing the safety of the blade fastening. The shims y can either be designed with protruding edges / 'according to FIG. 5, which easily counteract the rounded edges of the blade edges between the side part b and the blade bottom flap a
 EMI2.2
 Working methods are the same and shown in FIG.



   FIG. 18 shows a manner of fastening the blade according to FIG. 13 which differs from that according to FIG. 17 in that the projections on the groove walls, which are in the corresponding corrugations
 EMI2.3
   are present (Figs. 12 and 16).



   19 shows, compared to the other figures, a new arrangement of the embodiment of the blades according to FIGS. 2, 3 and 4, which can also be used for the other embodiments of the blade handles and in which the blade bottom is not flush with the upper edge of the groove, but rather there is clearance between this top edge and the bottom of the bucket. In this way it is possible to bezw with a continuous cylinder wall. Runner wall between the free end of the guide vane and the cylinder wall, respectively. to generate sufficient play between the free end of the guide vane and the rotor without it being necessary
 EMI2.4
 a completely secure closure of the steam channel.



   PATENT CLAIMS:
1. Impeller for steam turbines according to Patent No. 33246, but in such a way that the blades are inserted into grooves of the impeller, thereby gekenzneichnet that the blades in the grooves of the impeller by means of the mutually inclined, flat or in the direction of the radius
