Abstract

The supporting structure (1) of a cross-flow rotor absorbs bending and torsion loads. The blade ring frame is fully integrated in the lattice-work structure, the tie-rods forming continuous cross-flow blades. Adjacent blades of the module form distance-pieces in place of tubes. To avoid shear loads on the tie rods, the discs of two modules which are in contact can be prevented from twisting, the structure cross-struts being fixed to them adjacent to the tie rods. On large rotors, the intermediate discs can be replaced by cross-struts and the blades can be separately produced, being adjustably mounted on the structure. USE/ADVANTAGE - Supporting structure is for cross-flow rotor.

Description

Aus der Offenlegungsschrift JE 41 24 983 A1 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 gegeben ist. Auch sind Hinweise vorhanden, daß Einzelteile des Fachwerkes zur Wirkungsgradverbesserung oder für spezielle Nutzung unterschiedlich gestaltet sein können.The application of the spatial is from the publication JE 41 24 983 A1 Framework known as a supporting structure for cross-flow rotor in principle. Here different execution options are described and the Hin given that competition with axial and radial machines now given is. There are also indications that individual parts of the framework for Efficiency improvement or differently designed for special use could be.

Nicht erwähnt wurden Ausführungsbeispiele für kleine oder große Läuferdurch­ messer. Die Aufgabe der Erfindung ist es, diesen Mangel in Form eines Zusatzes zur o.a. Offenlegung zu beheben.Embodiments for small or large runners were not mentioned knife. The object of the invention is to overcome this defect in the form of an additive for the above Fix disclosure.

Während bei größeren Querstromläufern die Fachwerkkonstruktion unabhängig vom Schaufelringgitter wie in DE 41 24 983 A1 beschrieben zweckmäßig erscheint, ist in Maschinen nach DE 36 28 946 C2 das Schaufelgitter des Querstromläufers voll in die Tragkonstruktion integriert. Hier werden die Zuganker als durchgehende Querstromschaufel ausgebildet und die Distanzrohre durch die benachbarten Schaufeln der Module ersetzt. Um die Zuganker vor Scherkräften zu schützen, werden hier die sich berührenden Modulscheiben gegen Verdrehung gesichert. Außerdem werden die Querstreben des Fachwerkes neben den Zugankern an den Modulscheiben befestigt.While with larger cross-flow rotors the truss construction is independent of Blade ring grille as described in DE 41 24 983 A1 appears appropriate in machines according to DE 36 28 946 C2 the vane grille of the cross flow rotor is full integrated into the supporting structure. Here the tie rods are considered continuous Cross flow blade formed and the spacer tubes through the neighboring Buckets of modules replaced. To protect the tie rods from shear forces, Here the touching module disks are secured against rotation. In addition, the cross struts of the truss next to the tie rods on the Module disks attached.

Bei großen einzelligen Querstromläufern oder wenn es die Läufergeometrie er­ fordert, werden die Zwischenscheiben durch Fachwerkstreben (Fig. 1) ersetzt, also die Zwischenscheiben entfallen während die Stirnflächen wie auch immer gestaltet erhalten bleiben. Aus Montage- und Transportgründen werden hier die Querstromschaufeln separat gefertigt und an das Fachwerkgitter einstellbar montiert. (Unwuchtausgleich)In the case of large single-cell cross-flow runners or if the rotor geometry requires it, the intermediate washers are replaced by truss struts ( Fig. 1), so the intermediate washers are omitted while the end faces are kept in whatever form. For reasons of assembly and transport, the cross-flow blades are manufactured separately and mounted on the truss lattice in an adjustable manner. (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 adjustable.

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