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.
EMI1.1
lastung auf Zug dadurch, dass der Schaufelschaft nur in einem einzigen Halslager gelagert wird. 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.
In der Zeichnung ist der Erfindungsgenstand in beispielsweisen Ausführungsformen dargestellt.

In weiterer Ausgestaltung der Erfindung wird die Lauffläche des einzigen Halslagers kegel-oder kugelförmig ausgebildet, wobei der Kegelwinkel mindestens o gross sein muss, bzw. die Kugelfläche oder Fläche beliebiger Krümmung eine solche Form haben muss ; dass bei einer Drehung der Schaufel um den Punkt-4 die Schaufel sich von den Flächen D und C abhebt.

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.

EMI1.4
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.
