 EMI1.1 
 



   Die Erfindung betrifft die Befestigung der Schaufeln am Umfange eines Turbinenlaufrades vermittels der autogenen Stahlschweissung Die Schaufeln selbst werden in bekannter Weise dadurch hergestellt, dass gezogene oder gefräste Stahlstäbe vom gewählten Schaufelquerschnitt l in gleichlange, der Schaufel entsprechende Stücke geschnitten werden. 
 EMI1.2 
 wulstartigen Ring h mit einer oder mehreren Aussparungen i, wodurch die   Möglichkeit   gegeben ist, die gezogenen oder gefrästen, mit Nuten k versehenen Schaufeln l über den Wulst der Scheibe zu schieben.

   Um eine   gleichmässige Verteilung   der Schaufeln am Umfang der Scheibe zu sichern und um das Auftragen der   Lötmasse zu   vereinfachen, werden in   bekannter Weise zwischen zwei aufeinanderfolgende Schaufeln Stahlplättchen m gelegt, deren   
 EMI1.3 
 bekannter Weise die Verschweissung erfolgt. Im kalten Zustande werden endlich die Teile, die ausserhalb der Profile p liegen, abgedreht, so dass auch die Feststellung möglich ist, ol) zwischen Stahllot und Schaufeln die gewünschte innere Verbindung besteht. Der Scheibenkann auch mit mehreren wulstartigen Ringen ausgestattet werden.

 EMI1.1
 



   The invention relates to the attachment of the blades to the circumference of a turbine wheel by means of autogenous steel welding.The blades themselves are produced in a known manner by cutting drawn or milled steel rods of the selected blade cross-section l into pieces of the same length, corresponding to the blade.
 EMI1.2
 Bead-like ring h with one or more recesses i, which makes it possible to push the drawn or milled blades l provided with grooves k over the bead of the disk.

   In order to ensure an even distribution of the blades on the circumference of the disk and to simplify the application of the soldering compound, steel plates m are placed in a known manner between two successive blades
 EMI1.3
 in a known manner the welding takes place. In the cold state, the parts that lie outside the profiles p are finally turned off, so that it is also possible to determine ol) the desired inner connection exists between the steel solder and the blades. The disk can also be equipped with several bead-like rings.
