Description

       

  Automatischer Verstellpropeller, insbesondere für Windkraftmasehinen.    Vorliegende Erfindung betrifft einen  automatischen Verstellpropeller, insbesondere  für Windkraftmaschinen, und besteht darin,  dass an der die Rotationsachse des Propellers  nicht schneidenden Verdrehachse eines jeden  Propellerflügels ein Fliehkraftgewicht be  festigt ist, welches bei steigender Drehzahl  entgegen der Wirkung eines Hemmorganes  ausschwingt und den Propellerflügel zwecks  Vergrösserung seines Steigwinkels verdreht  und dadurch die Drehzahl des Propellers  regelt.  



  In der beiliegenden     Zeichnung    ist der  Erfindungsgegenstand in einer beispielswei  sen Ausführungsform dargestellt, und zwar  zeigt:  Fig. 1 einen Verstellpropeller mit ange  kuppeltem Generator in Seitenansicht,  Fig. 2 denselben in Vorderansicht.  



  Auf der Welle 1 des Generators 2 ist ein  Flansch 8 befestigt, welcher vier Propeller  lager 4 trägt. In diesen sind die     Propeller-          verdrehaohsen    5 gelagert, die einerends in    Propellerflügeln 6 endigen. Auf jeder Pro  pellerverdrehachse 5, die die Rotationsachse  des Propellers nicht schneidet, sitzt ein  Fliehkraftgewicht 7, das sich entgegen eines  an diesem angreifenden Hemmorganes 8,  z. B. einer Feder, bei steigender Drehzahl  der Welle 1 nach aussen bewegen kann und  dadurch die Propellerverdrehachse 5 dreht  und den Steigwinkel des zugehörigen Pro  pellerflügels vergrössert. Die Hemmorgane 8  sind anderends am Halter 9, der als Verlän  gerung der Welle 1 gedacht sein kann, be  festigt.

   Zur Begrenzung der     Achsenverdre-          hung    sind Anschläge 10 auf den Verdreh  achsen 5 und am diesen Anschlägen zuge  kehrten Lager 4 vorgesehen, so dass der Aus  schlagwinkel des Propellerflügels und in  folgedessen die Drehzahl der     Generatorwelle     1 innerhalb bestimmter Grenzen gehalten  werden kann.  



  Das Hemmorgan 8, das einer Verdrehung  eines Propellerflügels infolge der Fliehkraft  wirkung des Gewichtes entgegenwirkt, kann  statt aus einer Zugfeder auch aus einer Tor-      sionsfeder, die direkt auf der Verdrehachse 5  sitzt, bestehen.



  Automatic controllable pitch propeller, especially for wind power machines. The present invention relates to an automatic controllable pitch propeller, in particular for wind power machines, and consists in that a centrifugal weight is fastened to the axis of rotation of each propeller blade that does not intersect the axis of rotation of the propeller, which swings out at increasing speed against the action of an inhibiting element and the propeller blade for the purpose of enlarging its Angle of climb and thereby regulates the speed of the propeller.



  In the accompanying drawing, the subject matter of the invention is shown in an exemplary embodiment, namely: Fig. 1 shows a variable pitch propeller with a coupled generator in side view, Fig. 2 the same in front view.



  On the shaft 1 of the generator 2, a flange 8 is attached, which four propeller bearings 4 carries. The propeller twisting sleeves 5, which end in propeller blades 6 at one end, are mounted in these. On each Pro pellerverdrehachse 5, which does not intersect the axis of rotation of the propeller, sits a centrifugal weight 7, which is against an attacking on this inhibitor 8, z. B. a spring, with increasing speed of the shaft 1 can move outwards and thereby rotates the propeller rotation axis 5 and increases the pitch angle of the associated pro peller wing. The inhibitors 8 are on the other end on the holder 9, which can be thought of as an extension of the shaft 1, be strengthened.

   To limit the axis rotation, stops 10 are provided on the axes of rotation 5 and on bearings 4 facing these stops, so that the deflection angle of the propeller blade and consequently the speed of the generator shaft 1 can be kept within certain limits.



  The inhibiting element 8, which counteracts a rotation of a propeller blade as a result of the centrifugal force of the weight, can also consist of a torsion spring, which sits directly on the axis of rotation 5, instead of a tension spring.
