Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand vorliegender Erfindung ist ein Turbinenrad für Dampf- oder Gasturbinen nach dem Patent 112724, bei welchem aber die Füfse der Strahlstäbe schief zur Radachse stehen, zum Zweck, eine günstige Materialvertheilung bei den Strahlstä'ben zu erzielen und die Herstellung derselben zu erleichtern.The subject of the present invention is a turbine wheel for steam or gas turbines according to patent 112724, in which, however, the feet of the beam rods are oblique to the wheel axis stand for the purpose of achieving a favorable material distribution in the jet rods and to facilitate the manufacture of the same.
In beiliegender Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes veranschaulicht.The accompanying drawing shows an example of an embodiment of the subject matter of the invention illustrated.
Fig. ι zeigt einen Verticalschnitt durch das Turbinenrad in der Richtung der Achse. Fig. 2 ist eine Slirnansicht des theilweise geschnittenen und abgebrochenen Turbinenrades. Fig. 3 zeigt eine Hinteransicht und Fig. 4 einen Längsschnitt durch eine Schaufel nach J-K der Fig. 5. Fig. 5, 6, 7 und 8 sind Querschnitte nach bezw. A-B, C-D, E-F, G-H der Fig. 3, und Fig. 9 zeigt eine Einzeldarstellung.Fig. Ι shows a vertical section through the turbine wheel in the direction of the axis. Figure 2 is a plan view of the turbine wheel partially cut and broken away. 3 shows a rear view and FIG. 4 shows a longitudinal section through a blade according to JK of FIG. AB, CD, EF, GH of FIG. 3 and FIG. 9 shows an individual representation.
Auf der Turbinenwelle α sind zwei an einander liegende Nabenscheiben b, c angebracht, welche mit ihren Rändern die strahlenförmig angeordneten Stäbe d fassen. Nahe ihrem Umfange sind die Nabenscheiben b, c je mit einer ringförmigen Nuth versehen, in welchen je ein Scheibenring e,f liegt, die Ausschnitte g, h (Fig. 9) besitzen. Diese Scheibenringe sind durch Bolzen i mit den Nabenscheiben verbunden und sind derart eingestellt, dafs die Ausschnitte des einen Scheibenringes zu denen des anderen versetzt sind.On the turbine shaft α , two hub disks b, c lying on top of one another are attached, which with their edges hold the rods d arranged in a radial fashion. Near their circumference, the hub disks b, c are each provided with an annular groove, in each of which there is a disk ring e, f which has cutouts g, h (FIG. 9). These disk rings are connected to the hub disks by bolts i and are set in such a way that the cutouts of one disk ring are offset from those of the other.
In je zwei schräg einander gegenüberliegenden Ausschnitten stehen die Stäbe mit ihrem Fufs k derart, dafs dieser schief zur Radachse liegt (Fig. 2 und 9).In two cutouts that are diagonally opposite one another, the rods stand with their feet k in such a way that the latter is oblique to the wheel axis (FIGS. 2 and 9).
Dadurch ist eine Verdrehung der Stabquerschnitte gegenüber dem Fufse, die vorhanden sein müfste, wenn letzterer parallel zur Radachse stände und der Obertheil der Stäbe die in Fig. 9 angegebene Lage beibehalten sollte, vermieden (Fig. 5 bis 8).As a result, the rod cross-sections are twisted in relation to the base would have to be if the latter were parallel to the wheel axis and the upper part of the rods the should be maintained position indicated in Fig. 9, avoided (Fig. 5 to 8).
Dies hat den Zweck, eine günstige Materialvertheilung bei den Stäben zu erzielen und die Herstellung derselben zu erleichtern, ferner die Verwendung der Turbine als Axialturbine wesentlich zu erleichtern. Die Scheibenringe sind zweckmä'fsig verstellbar zu einander angeordnet, um die Füfse der Stäbe in verschiedenen Neigungen zur Radachse einstellen zu können.This has the purpose of achieving a favorable material distribution in the rods and the To facilitate production of the same, furthermore the use of the turbine as an axial turbine make it much easier. The disk rings are conveniently arranged to be adjustable to one another, in order to be able to adjust the feet of the rods in different inclinations to the wheel axis.
