  Leitschaufelregelung für Turbinen. 



   Es sind Turbinen bekannt, bei welchen die Verdrehung der Leitschaufeln durch einen gemeinsamen Ring erfolgt. Es sind auch Turbinen bekannt, bei welchen die Regulierhebel der Leitschaufeln sämtlich parallel zueinander angeordnet sind und auch bei Verdrehen der Leitschaufeln jeweils parallel zueinander bleiben. Bei diesen Konstruktionen waren ausserhalb des Regulierringes die Triebe am   Gestänge ange-   ordnet, welche den Regulierring in entsprechende Schwingung versetzten, um die richtige Leitschaufeleinstellung zu erzielen. Der   Raumbedarf   dieser   Antriebseinrichtungen   ist sehr gross.

   Zur Vermeidung dieses Nachteiles ist nun bei einer   Leitsehaufelregulierung für Turbinen,   bei welcher die parallel zueinanderliegenden Regulierhebel an einem gemeinsamen Regulierring angreifen, die   Anordnung erfindungsgemäss   derart getroffen, dass das die Verstellung des Regulierringes bewirkende Organ (Kurbelachse, Exzenterachse od.   dgl.)   sich innerhalb der vom Regulierring umschlossenen Zylinderfläche befindet. 



   Besonders zweckmässig wird der Regulierring von einem zentrisch zur   Turbinenachse gelagerten   Arm in Bewegung versetzt. Dies hat den Vorteil, dass   sämtliche     Kräfte in einem Punkt   vereint werden und keine Querkräfte vorhanden sind, welche ein Ecken od. dgl. zur Folge haben könnte. Ausserdem ist diese Konstruktion ausserordentlich einfach und leicht zu bedienen. 



   Auf der   Zeichnung ist   eine beispielsweise Ausführungsform des Erfindungsgegenstandes in Seitenansieht, zum Teil im Schnitt dargestellt. 
 EMI1.1 
 Bolzen 2 sitzen die Regulierhebel, die sämtlich zueinander parallel sind. Die Enden 5 der Regulierhebel greifen an einen Regulierring 6 an. Der   Regulierring 6   weist in seinem Durchmesser einen Träger 7 auf, der bei 8 an das Lager 9 des Regulierringes angelenkt ist. Das Lager 9 des Regulierringes umgreift das normale Wellenlager 10 der Turbinenwelle 77. Am Lager 9 ist ein Schneckenradsegment 12 angeordnet, mit welchem eine Schnecke 13 in Eingriff steht. Die   Schnecke 7. 3 wird durch   ein Handrad 14 über eine Welle   15   betätigt.

   Soll eine Verstellung der Leitschaufeln vorgenommen werden, so wird mittels des 
 EMI1.2 
 gleichen Betrag verstellt werden. Die erfindungsgemäss vorgeschlagene Konstruktion zeichnet sich durch grösste Einfachheit und leichte Bewegung aus.

  Guide vane control for turbines.



   Turbines are known in which the guide vanes are rotated by a common ring. Turbines are also known in which the regulating levers of the guide vanes are all arranged parallel to one another and remain parallel to one another even when the guide vanes are rotated. In these constructions, the drives were arranged on the linkage outside the regulating ring, which set the regulating ring in appropriate oscillation in order to achieve the correct guide vane setting. The space requirement of these drive devices is very large.

   In order to avoid this disadvantage, the arrangement according to the invention is made in a Leitsehaufelregulierung for turbines, in which the regulating levers lying parallel to one another act on a common regulating ring, that the organ causing the adjustment of the regulating ring (crank axis, eccentric axis or the like) is within the cylinder surface enclosed by the regulating ring.



   The regulating ring is particularly expediently set in motion by an arm mounted centrally to the turbine axis. This has the advantage that all forces are combined in one point and there are no transverse forces that could result in corners or the like. In addition, this construction is extremely simple and easy to use.



   In the drawing, an example embodiment of the subject matter of the invention is shown in a side view, partly in section.
 EMI1.1
 Bolts 2 sit the regulating levers, which are all parallel to each other. The ends 5 of the regulating levers engage a regulating ring 6. The regulating ring 6 has in its diameter a carrier 7 which is hinged at 8 to the bearing 9 of the regulating ring. The bearing 9 of the regulating ring engages around the normal shaft bearing 10 of the turbine shaft 77. A worm wheel segment 12 is arranged on the bearing 9, with which a worm 13 is in engagement. The worm 7. 3 is actuated by a handwheel 14 via a shaft 15.

   If the guide vanes are to be adjusted, the
 EMI1.2
 adjusted by the same amount. The construction proposed according to the invention is characterized by the greatest simplicity and easy movement.
