Abstract

The adjustable blade assembly is intended for flow machinery, such as for the stator blades of the turbine section or the guide blades of the pump section of a hydraulic torque converter. It comprises rotatable blades (1) which, for certain operating conditions, are rotated such that their entry sides point in the direction of flow (4). More than one, preferably two such blades are connected to form an assembly (12) which is rotatable about a common axis (11).

Verstellbare Schaufeln für StrömungsmaschinenAdjustable blades for flow machines

Die Erfindung bezieht sich auf drehbare inflexible Schaufeln für Strömungsmaschinen.The invention relates to rotatable inflexible blades for flow machines.

Bekannt sind drehbare Schaufeln insbesondere für Leiträder von hydrodynamischen Drehmomentwandlern. Entweder sind die Leitschaufeln insgesamt drehbar, oder drehbare Leitschaufeln sind festen Leitschaufeln vorgelagert. Dieser Stand der Technik wurde durch die internationale Patentanmeldung PCT/DE78/OOO34-dadurch verbessert, daß festen Schaufeln vorgelagerte drehbare Schaufeln für bestimmte Arbeitsbereiche der Strömungsmaschine soweit gedreht werden, daß die Hinterkante ihres Profiles in die Strömungsrichtung zeigt. Dabei kehrt sich die Krümmung dieser drehbaren Schaufeln bezüglich der Strömungsrichtung um, und es kann in Verbindung mit den nachgelagerten festen Schaufeln ein ideales Profil für diesen Arbeitsbereich der Strömungsmaschine erreicht werden.Rotatable blades are known, in particular for idlers of hydrodynamic torque converters. Either are the guide vanes rotatable as a whole, or rotatable guide vanes are upstream of fixed guide vanes. This prior art became through the international patent application PCT / DE78 / OOO34-thereby improved that fixed blades upstream rotatable blades for certain working areas of the turbomachine rotated so far that the trailing edge of their profile points in the direction of flow. The curvature of this is reversed rotatable blades with respect to the direction of flow, and it can be in connection with the downstream fixed blades ideal profile can be achieved for this working area of the turbomachine.

Der Nachteil dieser Konstruktion besteht darin, daß die Profillänge dieser drehbaren Schaufeln aufgrund des notwendigen Drehwinkels begrenzt ist durch den Abstand der Drehachsen zweier benachbarter Schaufeln. Da jedoch die Umlenkwirkung eines Strömungskanales bei gegebener Breite von einer ausreichenden Länge abhängt, ist eine befriedigende Kanallänge nur mit nachgelagerten festen Schaufeln zu erreichen.The disadvantage of this design is that the profile length this rotatable blades due to the necessary angle of rotation is limited by the distance between the axes of rotation of two adjacent blades. However, since the deflection effect of a flow channel for a given width is sufficient Depending on the length, a satisfactory channel length can only be achieved with downstream fixed blades.

Aufgabe der Erfindung ist es, diesen Nachteil zu beseitigen und eine so gute Führung des strömenden Arbeitsmediums durch die drehbaren Schaufeln zu erreichen, daß ggf. auch auf nachgelagerte feste Schaufeln verzichtet werden kann.The object of the invention is to eliminate this disadvantage and to achieve such a good guidance of the flowing working medium through the rotatable blades that possibly also on downstream ones fixed blades can be dispensed with.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwei benachbarte Schaufeln auf einer gemeinsamen Achse gelagert werden. Die Kanalbreite kann dadurch bei unveränderter Kanallänge gegenüber den bisher einzeln drehbaren Schaufeln nahezu halbiert werden. Damit ist auch eine befriedigende Führung des strömenden Arbeitsmediums ohne nachgelagerte feste Schaufeln möglich.This object is achieved in that two adjacent blades are stored on a common axis. The channel width can thereby with unchanged channel length compared to the previously individually rotatable blades are almost halved. This is also a satisfactory management of the flowing working medium without downstream fixed blades possible.

Anhand der Zeichnungen werden nachstehend die erfindungsgemäßen drehbaren Schaufeln noch näher veranschaulicht. Dabei zeigen in rein schematischer Weise:With reference to the drawings, the inventive rotatable blades illustrated in more detail. Show in a purely schematic way:

Der Pfeil 5 deutet hierbei die jeweilige Strömungsrichtung im Austrittsbereich des Schaufelgitters an. Die Schaufeln 1 sind hier analog Fig. 1 und 2 konstruiert. Fig. 4 ergibt sich aus Fig. 3 durch Linksdrehung der Schaufeln 1 um 120 Grad.3 and 4 show rotatable blades 1 according to the invention, such as they can e.g. be arranged at the outlet of a pump wheel 3. The arrow 5 here indicates the respective direction of flow in the outlet area of the blade grille. The shovels 1 are constructed here analogously to FIGS. 1 and 2. FIG. 4 results from FIG. 3 by turning the blades 1 counterclockwise by 120 degrees.

Fig. 5 zeigt einen Schnitt durch ein Schaufelpaar 1 längs der Linie 6 in Fig. 4. Das Schaufelpaar ist durch die beiden Lager 12 fest miteinander verbunden und so um die gemeinsame Achse 11 drehbar gelagert.Fig. 5 shows a section through a pair of blades 1 along the Line 6 in FIG. 4. The pair of blades are firmly connected to one another by the two bearings 12 and thus around the common axis 11 rotatably mounted.

Die Erfindung ist nicht auf die dargestellten Ausführungsformen beschränkt. Insbesondere kann das erfindungsgemäße Schaufelgitter mit und ohne vor- oder nachgelagerten festen oder ebenfalls drehbaren Schaufeln als Leit- oder Laufrad von Strömungsmaschinen eingesetzt werden. Ebenso ist es denkbar, daß mehr als zwei Schaufeln um eine gemeinsame Achse drehbar gelagert werden.The invention is not limited to the illustrated embodiments. In particular, the blade grille according to the invention with and without upstream or downstream fixed or rotatable blades as guide or impeller of flow machines can be used. It is also conceivable that more than two blades are rotatably mounted about a common axis.
