KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand der vorliegenden Erfindung ist eine Regelung für Turbinen, welche dadurch erfolgt, dafs die Leitschaufeln mittels eines Bolzens drehbar im Radkranz befestigt sind, so dafs durch die Drehung derselben der dem Wasser zur Verfügung stehende Querschnitt beliebig verändert werden kann. Bei der in den Fig. 1 bis 5 dargestellten Anordnung erfolgt die Drehung der Leitschaufeln durch einen Ring i, welcher um die Schaufeln d gelegt ist. An diesem Ring sind an der Unterseite Lappen / vorgesehen, welche mit einem Schlitz h versehen sind. In diesen Schlitz greift eine Rolle g, welche auf einem an der unteren Hälfte e der Leitschaufeln angebrachten Stift f sitzt (Fig. 4). Durch die Drehung des Ringes i werden diese Rollen mitgenommen und die Schaufeln somit verstellt.The subject of the present invention is a control system for turbines, which takes place in that the guide vanes are rotatably fastened in the wheel rim by means of a bolt, so that the cross section available to the water can be changed as desired by rotating them. In the arrangement shown in FIGS. 1 to 5, the rotation of the guide vanes takes place by means of a ring i which is placed around the vanes d . On the underside of this ring, tabs / are provided which are provided with a slot h . A roller g engages in this slot and sits on a pin f attached to the lower half e of the guide vanes (FIG. 4). By rotating the ring i , these rollers are taken along and the blades are adjusted.
Die Drehachse für die Schaufeln bilden die Bolzen c, welche in den Flantschen α und b gelagert sind. Bei der Bewegung der Schaufeln verschieben sich die Rollen g in den Schlitzen h. Der Ring i hat somit an diesen Rollen keine genügende Führung, d. h. er ist gegen eine seitliche Verschiebung nicht gesichert. Um diesem Uebelstande abzuhelfen, sind an den Schaufeln Ansätze k angebracht, deren äufsere Begrenzung ein centrisch mit der Drehachse der Schaufeln verlaufendes Kreisbogenstück bildet. Gegen diese Fortsätze legt sich der zur Drehung der Schaufeln benutzte Ring i an. Da die äufseren Flächen dieser Fortsätze Kreise um den Drehungsmittelpunkt der Schaufeln sind, so rollt der Ring bei der Drehung auf den Ansätzen k ab, so dafs der Ring von diesen Bogensegmenten geführt wird. Fig. ι zeigt die Schaufeln bei geschlossenen Leitkanälen, Fig. 2 in geöffnetem Zustande. Die Fig. 4 und 5 sind Einzeldarstellungen der Schaufeln und des zur Drehung derselben benutzten Ringes. Die Bewegung des Ringes kann im Uebrigen in beliebiger Weise erfolgen. Bei dem dargestellten Ausführungsbeispiel ist dazu ein Zahnrad benutzt, welches in einen an dem Ring befestigten Zahnkranz eingreift.The axis of rotation for the blades is formed by the bolts c, which are mounted in the flanges α and b. When the blades move, the rollers g move in the slots h. The ring i therefore does not have sufficient guidance on these roles, ie it is not secured against lateral displacement. In order to remedy this inconvenience, attachments k are attached to the blades, the outer boundary of which forms a segment of a circular arc running centrically with the axis of rotation of the blades. The ring i used to rotate the blades rests against these extensions. Since the outer surfaces of these extensions are circles around the center of rotation of the blades, the ring rolls off on the extensions k when it rotates, so that the ring is guided by these arc segments. Fig. Ι shows the blades with closed guide channels, Fig. 2 in the open state. Figures 4 and 5 are individual representations of the blades and the ring used to rotate the same. The movement of the ring can otherwise take place in any way. In the illustrated embodiment, a gear is used for this purpose, which engages in a ring gear attached to the ring.
