Description

Im Patent 904 400 ist ein Windrad in. verschiedenen Ausführungsfarmen, beschrieben, bei dem die Flügelverstellung durch das Kräftespiel zwischen dem Luftkraftmoment um die Flügelverstellachse und dem durch die Belastung des Windrades bestimmten:Windraddrehmomentherbeigeführt wird. Im folgenden sind weitere zweckentsprechende Ausführungsbeispiele beschrieben.In the patent 904 400 a wind turbine is in. Various execution farms, described, in which the wing adjustment by the play of forces between the air force moment around the blade adjustment axis and that determined by the load on the wind turbine: wind turbine torque caused will. Further appropriate exemplary embodiments are described below.

Die Kraftübertragung kann nämlich auch entweder durch eine Getriebewelle erfolgen, die innerhalb eines feststehenden Achszapfens. läuft, um den sich die Nabe dreht, oder dadurch, daß die Windrad-,velle in bekannter Weise umläuft und das Windrad auf ihr drehbar bzw. um den Flügelverstellweg schwenkbar gelagert ist. Ferner kann das im Hauptpatent beschriebene Regelprinzip mit einer an sich bekannten Drehzahlregelung z. B. mittels Fliehkraftpendel kombiniert werden.The power transmission can namely either through a gear shaft take place within a fixed axle journal. runs around which the Hub rotates, or in that the wind turbine, shaft rotates in a known manner and the wind turbine is rotatably mounted on it or pivotably about the blade adjustment path. Furthermore, the control principle described in the main patent can be used with a known per se Speed control z. B. be combined by means of a centrifugal pendulum.

In den Abb. i, 2 und 3 sind diese Möglichkeiten dargestellt. Gemäß Abb-. i ist innerhalb des feststehenden Windradachszapfens 15 eine normale Getriebewelle 6a gelagert, die über Arme 9b mit an den verstellbaren Flügelruten 4 der Flügel 5 angebrachten Hebeln i ie im Eingriff steht. Über die Eingriffstellen erfolgt die winddruck- und lastabhängige Abstimmung der aufeinander einwirkenden Kräfte.These possibilities are shown in Figs. I, 2 and 3. According to Fig-. i is a normal gear shaft within the stationary wind turbine axle pin 15 6a stored, the arms 9b with the adjustable wing rods 4 of the wing 5 attached levers i ie is engaged. The Wind pressure and load-dependent coordination of the forces acting on one another.

Nach Äbb. 2 ist die Windradnabe i auf einer umlaufenden Windradwelle 6b üblicher Bauart drehbar gelagert. Zapfen gt befinden sich am innerem. Ende der verstellbaren Flügelruten 4 und greifen in in die Windradwelle eingelassene Mitnehmerschlitze iid ein, so daß die Kraftübertragung und die Abstimmung der aufeinander einwirkenden Teilkräfte über diese Stelle unter Verdrehung der N abe gegenüber der Welle erfolgt.According to Fig. 2 is the wind turbine hub i on a rotating wind turbine shaft 6b of the usual design rotatably mounted. Spigots> are on the inside. end of adjustable wing rods 4 and engage in driver slots embedded in the wind turbine shaft iid one, so that the power transmission and the coordination of the interacting Partial forces are carried out via this point while rotating the hub with respect to the shaft.

Abb. 3 zeigt eine Kombination der gemäß Abb. 2 beschriebenen Flügelverstellung mit einer bekannten. Drehzahlregelung mittels Fliehkraftpendel. Das Fliehkraftpendel 31 wirkt an der Eingriffstelle 3o in bekannter Weise zusätzlich auf die Verstellflügelruten ein, so, daß die Flügelstellung gleichzeitig vom Winddruck, dem wirksamen Drehmoment und der Drehzahl abhängig ist.Fig. 3 shows a combination of the wing adjustment described in Fig. 2 with a well-known. Speed control by means of a centrifugal pendulum. The centrifugal pendulum 31 also acts at the engagement point 3o in a known manner on the adjustable wing rods a, so that the wing position simultaneously from the wind pressure, the effective torque and the speed is dependent.

Ergänzende Einrichtungen, wie z. B. Statikfedern, Dämpfungsvorrichtungen usw. ändern nichts am Wesentlichen des Erfindungsgedankens; sie sind deshalb in den Abbildungen nicht besonders dargestellt.Additional facilities, such as B. Static springs, damping devices etc. do not change anything in the essence of the idea of the invention; they are therefore in not specifically shown in the images.
