  Läufer für Asynchronmaschinen. 



   Will man bei der Herstellung von Läufern für Asynchronmaschinen zu grösseren Durchmessern übergehen, so kann man die bisher gebräuchlichen vollen Blechseheiben, aus denen der Läufer zusammengesetzt wird, nicht mehr verwenden, da die Breite der Blechtafeln, aus denen die Scheiben gestanzt werden, beschränkt ist. Man könnte nun daran denken, an Stelle der vollen Scheiben Segmente zu verwenden. Dieses Hilfsmittel genügt aber auch nicht, da zur Befestigung der Blechsegment eine Welle von grossem Durchmesser benötigt wird, in die die Segmente mit   Schwalbenschwänzen   eingesetzt werden müssen. Wellen mit einem grossen Durchmesser sind aber für hohe Umfangsgeschwindigkeiten nur sehr schwer herstellbar. 



   Nach der Erfindung werden   diese Übelstände dadurch   vermieden, dass der Läufer durch einen Hohlkern aus massivem Material gebildet, an dessen Umfange geblätterte Zähne eingesetzt werden. 



  An den Hohlkörper werden zweckmässig Wellenstümpfe angeflanscht. 



   Ein Ausführungsbeispiel ist in der Zeichnung veranschaulicht. In ihr bedeutet k den Hohlkern 
 EMI1.1 
 möglich ist.

  Rotor for asynchronous machines.



   If you want to switch to larger diameters in the manufacture of rotors for asynchronous machines, you can no longer use the previously used full sheet metal disks from which the rotor is assembled, since the width of the metal sheets from which the disks are punched is limited. One could now think of using segments instead of the full discs. However, this aid is not sufficient either, since a shaft of large diameter is required to fasten the sheet metal segments, into which the segments with dovetail tails must be inserted. However, shafts with a large diameter are very difficult to manufacture for high peripheral speeds.



   According to the invention, these inconveniences are avoided in that the rotor is formed by a hollow core made of solid material, on the circumference of which peeled teeth are used.



  Stub shafts are expediently flanged to the hollow body.



   An exemplary embodiment is illustrated in the drawing. In it, k means the hollow core
 EMI1.1
 is possible.
