Die Erfindung betrifft ein Verfahren zur Herstellung der Schaufelkränze gesondert vom Turbinenkörper, die in fertig gebautem Zustande eingesetzt und befestigt werden. Das neue Verfahren gestattet eine derart feste Verbindung zwischen den Schaufelkränzen und den übrigen umlaufenden Teilen, daß sie mit diesen ein untrennbares Ganzes bilden. Eine solche feste Verbindung ist besondersThe invention relates to a method for producing the blade rings separately from Turbine bodies that are used and fastened in the fully built state. That New methods allow such a firm connection between the blade rings and the other rotating parts so that they form an inseparable whole with them. Such a solid connection is special
ίο wichtig bei Radialturbinen, die aus ineinandergesteckten umlaufenden Schaufelkränzen bestehen, und bei denen die Schaufelkränze die Form eines durchbrochenen Zylinders mit einer oder mehreren Lochreihen haben. Die auf die Schaufeln wirkende Fliehkraft wird bei diesen nur von den die Schaufelenden verbindenden und in ihrer Lage sichernden Stirnscheiben aufgenommen.ίο important for radial turbines that are made of nested rotating blade rings exist, and in which the blade rings the Have the shape of an openwork cylinder with one or more rows of holes. the Centrifugal force acting on the blades is only provided by the blade ends connecting and securing in their position end disks added.
Die Enden der Schaufeln 1 (Fig. 1) werden zunächst in bekannter Weise in Schlitze verhältnismäßig dünner Blechstreifen 3 eingesetzt und zweckmäßig mit ihnen verschweißt oder verlötet.The ends of the blades 1 (Fig. 1) are initially used in a known manner in slots of relatively thin sheet metal strips 3 and appropriately welded or soldered to them.
Die so erhaltenen Schaufelreihen werden darauf mit stärkeren Rahmenteilen 4 vereinigt, indem überstehende Kanten des Blechstreifens 3, die in Fig. 2 strichpunktiert sind, derart umgebogen werden, daß sie den Verstärkungsring 4 umschließen.The rows of blades obtained in this way are then combined with stronger frame parts 4, by protruding edges of the sheet metal strip 3, which are dash-dotted in Fig. 2, be bent over in such a way that they enclose the reinforcing ring 4.
