Description

Unter dem Winddruck gegen eine Federkraft verstellbarer Flügel für Windkraftmaschinen. Es ist bekannt, die Schaufeln. oder Flügel gegenüber dem Winddruck nachgiebig und verstellbar zu machen, so daß sich ihre Arbeitsstellung bei verschiedenen Windgeschwindigkeiten ändert. Die Flügel werden entgegen dem Winddruck durch eine Federkraft in ihre Ruhestellung gedrückt.Blade for adjustable under the wind pressure against a spring force Wind power machines. It is known the shovels. or wings against the wind pressure to make flexible and adjustable, so that their working position at different Wind speeds changes. The wings are against the wind pressure by a Spring force pressed into its rest position.

Die Erfindung bezweckt, eine möglichst einfache, federnd drehbare Verbindung zwischen Flügel und Nabe herbeizuführen. Sie besteht darin, daß die Federung des Flügels durch die hohle Flügelspeiche erzielt wird. Besonders günstig wirkt die neue Eimichtung, wenn die rohrförmige Speiche längs der dem Flügel gegenüberliegenden Erzeugenden geschlitzt ist.The aim of the invention is to provide a resiliently rotatable as possible Create a connection between the wing and the hub. It consists in the suspension of the wing is achieved through the hollow wing spoke. Works particularly well the new egg device when the tubular spoke along the opposite side of the wing Generating is slotted.

Diese ist in der Zeichnung dargestellt. Der Flügel 3 wird von einem Röhr 8 getragen, das. mit einem Schlitz 5 versehen ist. Bei diesen Ausführungsformen ist es möglich, den größten Verdrehungswinkel des Flügels willkürlich, festzulegen. Man kann dies erreichen durch Wahl der vierdrehbaren Länge der Flügelspeiche oder durch Wahl der Länge des Längsschlitzes.This is shown in the drawing. The wing 3 is carried by a tube 8 which is provided with a slot 5. In these embodiments, it is possible to arbitrarily set the largest twist angle of the wing. This can be achieved by choosing the four-turnable length of the wing spoke or by choosing the length of the longitudinal slot.
