In Figur 1 erkennt man eine Turbine 1 mit Turbinenschaufeln 1.1 und einer Nabe 1.2. Die Schaufeln 1.1 sind von der Nabe 1.2 getragen. FIG. 1 shows a turbine 1 with turbine blades 1.1 and a hub 1.2. The blades 1.1 are supported by the hub 1.2.
Die Nabe ist innerseits an einem Gehäuse 2 gelagert. Das Gehäuse enthält u.a. einen hier nicht dargestellten Generator. Wie man sieht, zeigt die Nabe 1.2 einen Verstellring 3. Dieser ist koaxial zur Nabe 1.2 angeordnet und umschließt diese. Er ist mit dieser drehfest, kann aber auf der Nabe 1.2 in Richtung der Drehachse 1.3 der Turbine gleiten. The hub is mounted inside a housing 2. The housing contains i.a. a generator not shown here. As you can see, the hub 1.2 shows an adjusting 3. This is arranged coaxially to the hub 1.2 and surrounds them. It is non-rotatable with this, but can slide on the hub 1.2 in the direction of the axis of rotation 1.3 of the turbine.
Dem Verstellring 3 sind Schieber 4 zugeordnet, und zwar dieselbe Anzahl wie Schaufeln vorhanden sind. Verstellring 3 und Schieber 4 bilden gemeinsam die Versteileinrichtung. Dabei sind die Schieber 4 stabförmig. Am einen Ende eines jeden Schiebers greift der Verstellring 3 an, und am anderen Ende greift der Schieber seinerseits an einer Schaufel an. Verstellring 3 und Schieber 4 sind mit der Nabe 1.2 drehfest und laufen somit gemeinsam um. Der Angriffspunkt 5 eines Schiebers 4 an der Schaufel 1.1 ist auf Figur 2 erkennbar. The adjusting ring 3 are associated with slide 4, namely the same number as blades are present. Adjusting ring 3 and slide 4 together form the adjusting device. The slides 4 are rod-shaped. At one end of each slider, the adjusting ring 3 engages, and at the other end, the slider engages in turn on a blade. Adjustment ring 3 and slide 4 are rotationally fixed to the hub 1.2 and thus run together. The point 5 of a slider 4 on the blade 1.1 can be seen in FIG.
Das axiale Verschieben des Verstellrings 3 und damit auch der einzelnen Schieber 4 erfolgt mittels eines Aktuators, der hier nicht gezeigt ist. Eine geringfügige Axialverschiebung der Versteileinrichtung 3, 4 kann bereits zu einer ausreichenden Verstellung der Neigung (Pitch) der Schaufeln 1.1 führen. Die zweite Ausführungsform der Erfindung ist in den Figuren 3 und 4 dargestellt. The axial displacement of the adjusting ring 3 and thus also the individual slide 4 by means of an actuator, which is not shown here. A slight axial displacement of the adjusting device 3, 4 can already lead to a sufficient adjustment of the inclination (pitch) of the blades 1.1. The second embodiment of the invention is shown in FIGS. 3 and 4.

Die Schieber 4 sind in ihren Endbereichen als Zahnstangen ausgeführt. Die Zahnstangen kämmen im montierten Zustand mit dem Zahnring 1.5. Figure 4 shows the adjusting device with the adjusting ring 3 in settlement. The adjusting ring 3 carries in the present case three slides 4 - equal to the number of blades 1.1. The slides 4 are designed in their end regions as racks. The racks comb in the assembled state with the toothed ring 1.5.
Der Gegenstand gemäß Figur 5 gehört zum Stande der Technik. Er betrifft eine Kaplan-Turbine 1 mit einer Anzahl von Turbinenschaufeln 1.1 und einer Nabe 1.2. Die Turbinenschaufeln 1.1 sind verstellbar. Ein Kegel radgetriebe 6 überträgt das von der Turbine 1 erzeugte Drehmoment auf einen Generator 7. The article according to FIG. 5 belongs to the state of the art. It relates to a Kaplan turbine 1 with a number of turbine blades 1.1 and a hub 1.2. The turbine blades 1.1 are adjustable. A bevel gear 6 transmits the torque generated by the turbine 1 to a generator. 7
