Description
Zahnradpumpe mit zwei ineinanderliegenden Zahnrädern. Gegenstand vorliegender' Erfindung ist eine Zahnradpumpe mit zwei ineinanderliegenden Zahnrädern, z. B. für Viskoseförderung zur Herstellung -von Kunstseide.Gear pump with two nested gears. Subject of the present ' Invention is a gear pump with two nested gears, z. B. for Viscose conveying for the production of rayon.
Das Neue besteht darin, daß, um bei Abnutzung der Zähne das Lecken der Flüssigkeit durch die Zähne hindurch zurück nach dem Einlaß der Pumpe unmöglich zu machen, das Innenzahnrad durch verstellbar gelagerte sichelförmige Füllstücke radial einstellbar gemacht ist. Die radiale V erstellbarkeit der Zahnräder- von Zahnradpumpen ist an sich bekannt.The new thing is that in order to prevent licking when the teeth wear out the fluid back through the teeth after the inlet of the pump is impossible to make the internal gear through adjustable crescent-shaped filler pieces is made radially adjustable. The radial V createability of the gears from Gear pumps are known per se.
In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt.In the drawing is an embodiment of the subject matter of Invention shown.
Abb. i ist eine allgemeine Ansicht, teilweise im Schnitt, Abb. 2 ein senkrechter Schnitt nach Linie z-2 der Abb. i.Fig. I is a general view, partly in section, Fig. 2 a vertical section along line z-2 of Fig. i.
Abb. 3 ist ein senkrechter Schnitt, im wesentlichen nach der Linie 3-3 der Abb. 2. Abb, 4 ist ein Schnitt nach der Linie 4-4 der Abb. 3.Fig. 3 is a vertical section, essentially along the line 3-3 of Fig. 2. Fig. 4 is a section along line 4-4 of Fig. 3.
Abb. 5 zeigt eine Einzelheit schaubildlich. i ist das Gehäuse, welches aus zwei durch Schrauben 4 miteinander verschraubten Teilen 2, 3 zusammengesetzt ist. Zwischen den Teilen ist eine Platte 5 angeordnet, welche einen kreisförmigen, die Pumpenkammer bildenden Ausschnitt 6 besitzt. 7 ist der Einlaß und 8 der Auslaß für die Flüssigkeit. Innerhalb des Ausschnitts befindet sich das Außenrad 9 mit Innenverzahnung, das von den Wandungen der Pumpenkammer geführt wird. Ein mit Außenverzahnung versehenes Innenrad io ist mit dem Außenrad 9 mit Innenverzahnung im Eingriff. Dieses Zahnrad io sitzt auf einer angetriebenen Welle i i derart, daß eine geringe Radialbewegung (Spiel 12) möglich ist (Abb. 3). 13 und 14 sind sichelförmige Füllstücke, die am Teil 2 durch Stellschrauben 15 befestigt werden und in an sich bekannter Weise den Raum zwischen den nicht in Eingriff stehenden Teilen der Zahnräder zwecks Trennung- des Einlasses vom Auslaß ausfüllen.Fig. 5 shows a detail graphically. i is the housing, which is composed of two parts 2, 3 screwed together by screws 4. A plate 5 is arranged between the parts and has a circular cutout 6 which forms the pump chamber. 7 is the inlet and 8 the outlet for the liquid. Inside the cutout is the outer wheel 9 with internal teeth, which is guided by the walls of the pump chamber. An internal gear provided with external teeth is in mesh with the external gear 9 with internal teeth. This gear wheel io sits on a driven shaft ii in such a way that a slight radial movement (play 12) is possible (Fig. 3 ) . 13 and 14 are sickle-shaped filler pieces which are fastened to part 2 by adjusting screws 15 and, in a manner known per se, fill the space between the non-engaging parts of the gears for the purpose of separating the inlet from the outlet.
Bei Drehung der Welle i i wälzt sich das Rad io an dem Rad 9 ab, und die bei 7 üintretende Flüssigkeit wird an beiden Enden der Füllstücke 13 und 14 in den Zahnlücken mitgenommen und dem Auslaß 8 zugeführt. Wenn die Zahnräder sich abnutzen, können die Füllstücke vermöge der Anwendung von Langlöchern 16 nachgestellt werden, 'so daß die Zahnräder enger zusammenkommen und ein Übertritt von Flüssigkeit zwischen den Eingriffsstellen der Zahnräder verhindert wird.When the shaft i i rotates, the wheel io rolls on the wheel 9, and the liquid entering at 7 becomes at both ends of the filler pieces 13 and 14 entrained in the tooth gaps and fed to the outlet 8. When the gears turn wear, the filler pieces can be readjusted by using elongated holes 16 'so that the gears come closer together and a transfer of fluid is prevented between the points of engagement of the gears.
