Description

Aus der Patentschrift DE 41 24 983 C2 ist die Anwendung des räumlichen Fachwerkes als Tragkonstruktion für Querstromläufer im Grundsatz bekannt. Hier werden verschiedene Ausführungsmöglichkeiten beschrieben und der Hin­ weis gegeben, daß damit der Wettbewerb mit Axial- und Radialmaschinen jetzt für alle Größen gegeben ist. Auch sind Hinweise vorhanden, daß Einzel­ teile des Fachwerkes zur Wirkungsgradverbesserung oder für spezielle Nutzung unterschiedlich gestaltet sein können.From the patent DE 41 24 983 C2 is the application of the spatial Truss known in principle as a supporting structure for cross-flow rotor. Here various execution options are described and the Hin given that competition with axial and radial machines is now available for all sizes. There are also indications that individual parts of the framework to improve efficiency or for special use can be designed differently.

Nicht erwähnt wurden Ausführungsbeispiele für kleine oder große Läuferdurch­ messer und Maßnahmen zur Konstruktionsoptimierung. Die Aufgabe der Erfindung ist es, diesen Mangel zu beheben.Embodiments for small or large runners were not mentioned knives and measures for design optimization. The object of the invention is to remedy this deficiency.

Während bei größeren Querstromläufern die Fachwerkkonstruktion unabhängig vom Schaufelringgitter, wie in DE 41 24 983 C2 beschrieben, zweckmäßig erscheint, ist bei Querstromläufern mit geringem Schaufelringgitterdurchmesser die Trag­ konstruktion voll zu integrieren, indem die Zuganker als durchgehende Quer­ stromschaufel ausgebildet und die Distanzrohre durch die in Umfangsrichtung benachbarten Schaufeln der Module ersetzt werden.While with larger cross-flow rotors, the truss construction is independent of Blade ring grille, as described in DE 41 24 983 C2, appears expedient, is the support for cross-flow rotors with a small blade ring grille diameter construction fully integrated by using the tie rods as a continuous cross current blade and the spacer tubes through the circumferential direction neighboring blades of the modules are replaced.

Um die Zuganker vor Scherkräften zu schützen, können bei der Erfindung die sich berührenden Modulscheiben gegen Verdrehung gesichert werden. Außerdem können die Querstreben des Fachwerkes neben den Zugankern an den Modulschei­ ben befestigt sein.In order to protect the tie rods from shear forces, the touching module disks are secured against rotation. also can the cross struts of the truss next to the tie rods on the module ben attached.

Bei großen einzelligen Querstromläufern oder wenn es die Läufergeometrie erfordert, können die Zwischenscheiben durch Fachwerkstreben (Fig. 1) er­ setzt werden, also die Zwischenscheiben entfallen, während die Stirnflächen, wie auch immer gestaltet, erhalten bleiben. Aus Montage- und Transportgründen werden bei der Erfindung die Querstromschaufeln separat gefertigt und an das Fachwerkgitter einstellbar montiert (Unwuchtausgleich).In the case of large single-cell cross-flow rotors or if the rotor geometry requires it, the intermediate washers can be replaced by truss struts ( FIG. 1), so the intermediate washers are omitted while the end faces, however designed, are retained. For assembly and transport reasons, the cross-flow blades are manufactured separately in the invention and are adjustably mounted on the truss grid (unbalance compensation).

Das Konstruktionsprinzip für große Querstromläufer wird in Fig. 1 und 2 dargestellt. Es handelt sich um ein 12-teiliges Fachwerkgitter, an das die 1/4-Kreisschaufeln einstellbar montiert sind.The design principle for large cross-flow rotors is shown in Figs. 1 and 2. It is a 12-part truss on which the 1/4 circular blades are adjustably mounted.

Die dem senkrecht stehenden Querstromläufer (Fig. 2) zugeordnete Fläche (schwenkbares Segel) dient bei auf dem Querstromprinzip beruhenden Windkraftanlagen der Leistungsoptimierung durch Strömungsbeeinflussung.The surface (swiveling sail) assigned to the vertical cross-flow rotor ( FIG. 2) is used in wind power plants based on the cross-flow principle to optimize the performance by influencing the flow.
