KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der Erfindung ist eine Befestigung für die Schaufeln der Räder für Dampfoder Gasturbinen. Diese kennzeichnet sich gegenüber der Befestigungsweise, nach weleher die Schaufeln durch Querbolzen gehalten und in seitliche Einschnitte der Scheiben eingesetzt sind, sowie gegenüber derjenigen Be-. festigungsweise, nach welcher die mit nasenförmigen Vorsprüngen versehenen Schaufel-The invention relates to a fastening for the blades of the wheels for steam or Gas turbines. This distinguishes itself from the method of attachment, according to which the blades are held in place by cross bolts and inserted into side incisions in the discs are, as well as to those loading. method of consolidation, according to which the nose-shaped Blade provided with protrusions

l'o fuße in dementsprechende Nuten der Scheiben eingreifen, und anderen gegenüber dadurch, daß die mit rechteckigem oder anderem Querschnitt versehenen Schaufelfüße in die Lücken seitlich an den Scheiben angeordneter Zähne b eingesetzt und daß sie am Ende derart umgebogen sind, daß sich die Umbiegungen a gegen die nach der Achse gerichteten Stirnflächen der Zahne legen.l'o feet engage in corresponding grooves of the disks, and others in that the blade feet provided with a rectangular or other cross-section are inserted into the gaps in teeth b arranged on the side of the disks and that they are bent at the end in such a way that the bends a place against the end faces of the teeth facing the axis.

Die Befestigung ist auf der Zeichnung dargestellt, und zwar zeigt Fig. 1 eine Schaufel von der Kopfseite aus gesehen, Fig. 2 eine Rücken- und Fig. 3 eine Seitenansicht derselben. Die Fig. 4, 5 und 9 zeigen die gezahnten Scheiben mit den eingesetzten Schaufein in radialem und in Flächenschnitt. Dagegen zeigen die Fig. 6, 7 und 8 die Scheiben von deren Rande aus gesehen. Die Zahnung an den Scheiben kann verschieden angeordnet werden. Die Zähne können sich z. B., wie Fig. 6 zeigt, nur an der einen Scheibe befinden und die Breite derselben kann etwa der Breite der Schaufelfüße entsprechen, sie können aber auch, wie in Fig. 7 und 8 dargestellt, an beiden Scheiben angebracht werden, und zwar können sie dann entweder die gleiche Breite erhalten wie bei der in Fig. 6 dargestellten Anordnung, wobei die Zähne, wie Fig. 8 zeigt, an beiden Scheiben, und zwar versetzt zueinander angeordnet werden, oder die Breite der Zähne kann gleich der halben Breite der Schaufelfüße sein, in welchem Falle die Scheiben so gestellt werden, daß die Zähne gegeneinander stoßen (vergl. Fig. 7). Es ist darauf zu achten, daß die Schaufelfüße möglichst gut in die Zahnlücken passen und daß die Länge der Schaufelfüße von der Umbiegung α bis zum Kopfe der Länge der Zähne entspricht.The attachment is shown in the drawing, namely FIG. 1 shows a blade seen from the head side, FIG. 2 shows a back and FIG. 3 shows a side view of the same. 4, 5 and 9 show the toothed disks with the blades inserted in radial and surface sections. In contrast, FIGS. 6, 7 and 8 show the disks seen from their edge. The teeth on the discs can be arranged in different ways. The teeth can z. B., as Fig. 6 shows, are only on one disk and the width of the same can approximately correspond to the width of the blade roots, but they can also, as shown in Fig. 7 and 8, be attached to both disks, namely can they then either have the same width as in the arrangement shown in FIG. 6, the teeth, as FIG. 8 shows, being arranged on both disks, namely offset from one another, or the width of the teeth can be equal to half the width of the blade roots be, in which case the disks are placed so that the teeth abut against each other (see. Fig. 7). It must be ensured that the blade roots fit into the tooth gaps as well as possible and that the length of the blade roots from the bend α to the head corresponds to the length of the teeth.
