Description

Wasserturbine, Schiffsschraube Q. dgl. mit drehbaren, in der Nabe gelagerten und durch Bunde gesicherten Laufschaufeln. Bei Wasserturbinen mit drehbaren Laufschaufeln und Schiffsschrauben mit drehbaren Flügeln übt der auf die Schaufeln wirkende Wasserdruck ein großes Biegungsmoment auf die in der Nabe gelagerten Drehzapfen der Schaufeln aus.Water turbine, propeller Q. Like. With rotatable, in the hub bearing blades secured by collars. In water turbines with rotatable The blades and propellers with rotating blades are used on the blades acting water pressure exerts a large bending moment on the pivot pins mounted in the hub of the shovels.

Infolge der notwendigerweise gedrängten Bauart der Naben müssen die Zapfen sehr kurz und die Bunde, die als kreisrunde Scheiben ausgeführt werden, im Durchmesser möglichst knapp gehalten werden. Die Bunde haben hauptsächlich das Kippen der Schaufeln aufzufangen, und wegen ihres geringen Durchmessers werden die Flächenpressungen und dementsprechend auch die Abnutzungen sehr groß. Bereits nach kurzer Betriebszeit stellen sich die Schaufelachsen schief und es treten Klemmungen auf, die zu einem Versagen der Drehvorrichtungen und zu kostspieligen Ausbesserungen führen.As a result of the necessarily compact design of the hubs must Cones very short and the collars, which are designed as circular disks, in the Diameter should be kept as tight as possible. The frets mainly have tilting of the blades, and because of their small diameter, the surface pressures and accordingly the wear and tear is very high. Already after a short period of operation If the blade axes are crooked and there are clamps that lead to a Rotation failure and costly repairs can result.

Die vorliegende Erfindung bezweckt, diesen Übelstand erheblich zu mildern.The present invention aims to remedy this drawback considerably mitigate.

Der Erfindungsgegenstand ist in Fig. i im Vertikalschnitt dargestellt, während Fig. 2 den wagerechten Schnitt A -A durch die Mittelebene der Schaufelachsen zeigt.The subject of the invention is shown in Fig. I in vertical section, while Fig. 2 shows the horizontal section A-A through the center plane of the blade axes shows.

Die. Nabe i einer Wasserturbine ist an der Flansche 2 der Turbinenwelle 3 angeschraubt. Die Nabe trägt beispielsweise vier Schaufeln q., die in der Regel zur Richtung der Turbinenachse sehr flach gestellt sind, so daß der auf die Schaufeln wirkende Wasserdruck eine Richtung 5 hat, die nur um einen kleinen Winkel 6 von der Turbinenachse abweicht. Das Kippmoment der im Schwerpunkt der Schaufeln angreifenden Kraft5 wird in der Hauptsache durch die beiden Schaufelbunde 7 und 8 abgefangen, welche sich gegen die angedrehten Flächen 9 und io der Nabe abstützen.The. Hub i of a water turbine is on flange 2 of the turbine shaft 3 screwed on. The hub carries, for example, four blades q., As a rule to the direction of the turbine axis are placed very flat, so that the on the blades acting water pressure has a direction 5, which is only at a small angle 6 of deviates from the turbine axis. The overturning moment of the attacking in the center of gravity of the blades Force5 is mainly absorbed by the two shovel collars 7 and 8, which are supported against the turned surfaces 9 and io of the hub.

Durch Kurbeln ii in Verbindung mit Lenkern 12 werden die Schaufeln q. in bekannter Weise durch die achsial bewegliche Muffe 13 gedreht.By cranking ii in conjunction with links 12, the blades q. rotated in a known manner by the axially movable sleeve 13.

Nach der vorliegenden Erfindung werden die Bunde 7 und 8, nachdem die Kraftrichtung 5 nur wenig von der Achsenrichtung abweicht, nicht als kreisrunde Scheiben ausgebildet, sondern dem verfügbaren Raum entsprechend quer zur Turbinenachse schmal und in der Richtung der Turbinenachse lang gehalten, damit die Flächenpressung der Bunde herabgemindert wird.According to the present invention, the collars 7 and 8 after the direction of force 5 deviates only slightly from the axial direction, not as circular Discs formed, but according to the available space transversely to the turbine axis narrow and long in the direction of the turbine axis, so that the surface pressure the covenant is reduced.

Die Erfindung läßt sich für jede Schaufelzahl und in gleicher Weise auch bei Schiffsschrauben u. dgl. anwenden.The invention can be used for any number of blades and in the same way also apply to propellers and the like.
