  LaufradnabemitdrehbarenSchaufelnfürWasserturbinen. 



   Bei den bisher bekannten Laufrädern mit drehbaren schaufeln erfolgt die Lagerung des Schaufelschaftes in zwei zylindrischen oder   konisehen Halslagern   und einem   Spurlager. Infolge dieser Lagenuns'   wird der Sehaufelsehaft auf Biegung beansprucht.

Dieses   Halslager wird vorteilhaft mit grossem Durchmesser und kleiner Baulänge ansgeführt, einerseits um die   Zugbelastung des   Seh. aufelschaftes klein zu machen, anderseits um   die   Beanspruchung auf Biegung auch   innerhalb der Halslagerlänge zu vermeiden.

  Impeller hub with rotating blades for water turbines.



   In the previously known impellers with rotatable blades, the blade shaft is mounted in two cylindrical or conical neck bearings and a thrust bearing. As a result of this Lagenuns' the Sehaufelsehaft is stressed in bending.
 EMI1.1
 load on train due to the fact that the blade shaft is only stored in a single neck bearing. This neck bearing is advantageously designed with a large diameter and a small overall length, on the one hand to reduce the tensile load on the eye. on the other hand, to avoid the stress on bending within the neck bearing length.



   In the drawing, the subject matter of the invention is shown in exemplary embodiments.
 EMI1.2
 
 EMI1.3
 
 EMI1.4
 to avoid getting stuck and, on the other hand, to favor a setting option as far as possible.



   In a further embodiment of the invention, the running surface of the single neck bearing is designed to be conical or spherical, the cone angle having to be at least o large, or the spherical surface or surface of any curvature having to have such a shape; that when the blade rotates around point -4, the blade lifts off surfaces D and C.
