Description
Windkraftmaschine mit gekrümmten Windflügeln Die Erfindung bezieht sich auf eine vertikale Windkraftmaschine, bei der das Windrad, das von einem Gerüst getragen wird, eine mit gekrümmten Windflügeln ausgestattete. Nabe aufweist.Wind power machine with curved blades The invention relates focus on a vertical wind power machine where the wind turbine is supported by a scaffold is carried, one equipped with curved wind blades. Has hub.
Die konkave Fläche der gekrümmten Flügel geht von der Radnabe tangential aus und läuft am Umfange des Windrades in entgegengesetzter Richtung aus.The concave surface of the curved blades extends tangentially from the wheel hub and runs out at the circumference of the wind turbine in the opposite direction.
Durch dieErfindungwerden diese gekrümmten Flügel des Windrades in L- oder winkliger Form ausgebildet, durch welche die Antriebsenergie des Windes im höheren Grad zum Antrieb des Flügelrades ausgenutzt wird. Erfindungsgemäß wird dies dadurch erreicht, daß die Flügel aus einem inneren gekrümmten, zur Nabe tarigentialen Teil und aus einem äußeren, ebenfalls gekrümmten, aber längeren Teilzusammengesetzt sind, wobei der Übergang des einen Teils in den anderen mit einer Krümmung mit kleinem Halbmesser erfolgt.By means of the invention, these curved blades of the wind turbine are designed in an L- shape or angled shape, by means of which the drive energy of the wind is used to a greater extent to drive the fan wheel. According to the invention, this is achieved in that the wings are composed of an inner curved part, tarigential to the hub, and an outer, also curved, but longer part, the transition from one part to the other with a curvature of a small radius.
Diese Gestaltung der Radflügel bietet den Vorteil, daß der Wind, nachdem er seine Treibwirkung auf den kürzeren L-förmigen Schenkel ausgeübt hat, während der Weiterdrehung des Rades seine Wirkung auf den längeren L-förmigen Schenkel ausübt und so eine starke Hebelwirkung auf das Rad bewirkt, die noch dadurch unterstützt wird, daß die -Nabe den Windflügeln gegenüber groß bemessen ist. L-förmige Flügel sind zwar an und für sich schon bekannt, aber die besondere erfindungsgemäß gewählte Form ist neu, ebenso wie deren Kombination mit einer Nabe von verhältnismäßig großem Durchmesser.This design of the wheel wing offers the advantage that the wind after he has exerted his driving effect on the shorter L-shaped leg while the further rotation of the wheel exerts its effect on the longer L-shaped leg and so causes a strong leverage on the wheel, which is still supported by it is that the hub is large compared to the wind blades. L-shaped wings are already known per se, but the special one chosen according to the invention Shape is new, as is its combination with a hub of relatively large size Diameter.
Die. Zeichnung veranschaulicht eine Ausführungsform des Erfindungsgegenstandes.The. Drawing illustrates an embodiment of the subject matter of the invention.
Abb. i stellt eine erfindungsgemäße Windkraftmaschine mit stehender Welle im Aufriß dar; Abb. 2 zeigt dieselbe Windkraftmaschine im Grundriß.Fig. I shows a wind power machine according to the invention with a standing position Shaft in elevation; Fig. 2 shows the same wind power machine in plan.
Diese Windkraftmaschine besitzt ein von einem Gerüst getragenes Windrad G. Dieses Rad ist auf der stehenden Welle i befestigt und besteht aus einer Trommel oder Nabe 2 mit daran befestigten radialen Windflügeln, welche das erfindungsgemäß gewählte Profil aufweisen. Das Profil ist annähernd L-förmig; die zwei Schenkel des L sind gekrümmt und gehen ineinander durch eine Krümmung mit kleinem Halbmesser über. Der an der Trommel befestigte Schenkel q. ist tangential zu der zylindrischen Mantelfläche . der Trommel. Die äußeren Flügelenden 3 sind durch Ringe 5, beispielsweise aus Metallblech, miteinander verbunden.This wind power machine has a wind turbine G supported by a frame. This wheel is attached to the standing shaft i and consists of a drum or hub 2 with attached radial wind blades which have the profile selected according to the invention. The profile is approximately L-shaped; the two legs of the L are curved and merge into one another through a curvature with a small radius. The leg q attached to the drum. is tangential to the cylindrical surface. the drum. The outer wing ends 3 are connected to one another by rings 5, for example made of sheet metal.
Die Welle i ist in den Lagern 6, 7, 8 sowie in einem Spurlager 9 drehbar, während ein oberes Lager io mittels Zugdrähten ii o. dgl. mit in dein Boden eingelassenen Masten 12 verbunden ist; Verankerungsseile 13 erhöhen noch weiter die Steifigkeit des Systems. Die Übertragung der Drehbewegung von der Radwelle i auf die Triebwelle 14 erfolgt mittels Kegelräder 15 und 16 oder auf irgendeine andere bekannte Weise.The shaft i is rotatable in the bearings 6, 7, 8 and in a thrust bearing 9, while an upper bearing io is embedded in the ground by means of pull wires ii or the like Mast 12 is connected; Anchoring ropes 13 increase the rigidity even further of the system. The transmission of the rotary motion from the wheel shaft i to the drive shaft 14 is effected by means of bevel gears 15 and 16 or in any other known manner.
Das Unterschiedliche dieser neuen Windturbine gegenüber den bisher bekannt gewordenen Ausführungformen besteht somit darin, daß der Krümmung der Schaufeln eine L-förmige Gestalt gegeben wird, wie sie an sich bei Schaufeln von Kreiselmaschinen nicht neu ist, indem der innere tangentiale Schenkel durch eine stärkere Krümmung in den äußeren Schenkel, dessen Krümmung nach außen wieder abnimmt, derart übergeht, daß der äußere Schenkel der Schaufel länger ist als der innere. Durch diese Ausbildung der Krümmung wird die Beaufschlagung der Schaufeln günstiger, so daß ein besonderer Verteiler, wie er bei dem obengenannten Windrade angewendet wird, entbehrlich wird.The difference between this new wind turbine and the previous ones Embodiments that have become known thus consist in that the curvature of the blades an L-shaped shape is given, as is the case with blades of gyroscopes is not new by adding the inner tangential leg by a greater curvature merges into the outer leg, the curvature of which decreases again towards the outside, in such a way that that the outer leg of the blade is longer than the inner one. Through this training the curvature is the loading of the blades more favorable, so that a special Distributor, as used in the above-mentioned wind turbine, is dispensable.
