Description

llehrfach-Zahnradpumpe zum Ölen von Kraftmaschinen. Bei Zahnradpumpen, die als ölpumpen für Kraftmaschinen verwendet werden, und bei denen das Getriebe in einem besonderen Raum untergebracht ist, ist es erwünscht, das Getriebe und die zugehörigen Lagerstellen in einfacher Weise zu ölen. Ferner ist es erwünscht, vor der Inbetriebsetzung der Kraftmaschine durch eine Handpumpe Öl in die Maschine einzuführen, ohne daß die Ölpumpe dabei hinderlich ist.Teaching gear pump for oiling prime movers. For gear pumps, which are used as oil pumps for prime movers, and in which the gearbox is housed in a special room, it is desirable to have the gearbox and the to oil associated bearings in a simple manner. It is also desirable before before starting up the engine, introducing oil into the machine by means of a hand pump, without the oil pump being a hindrance.

Nach der Erfindung wird dies dadurch erreicht, daß zwischen dem Getrieberaum und dem Saug- oder Druckraum der Pumpe eine Verbindung besteht. Es kann dann Öl aus einem dieser Räume in den Getrieberaum der Pumpe eintreten und die dort befindlichen Teile ölen. Es kann ferner durch eine an den Getrieberaum angeschlossene Leitung zur Einführung von Zusatzöl über den Getrieberaum und ebenfalls durch die Verbindung mit einem Saug= oder Druckraum der Pumpe 01 bei stillstehender Pumpe von Hand zur Maschine geleitet werden.According to the invention, this is achieved in that there is a connection between the gear chamber and the suction or pressure chamber of the pump. Oil can then enter the gearbox of the pump from one of these spaces and oil the parts located there. It can also be passed by hand to the machine when the pump is at a standstill through a line connected to the gearbox for introducing additional oil via the gearbox and also through the connection with a suction or pressure chamber of the pump 01.

,Auf der Zeichnung ist in Abb. i die Pumpe von außen dargestellt, in Abb. a in einem senkrechten und in Abb.3 in einem wagerechten Schnitt. Die Pumpe ist eine Mehrfach-Zahnradpumpe, die unmittelbar an das Gehäuse, beispielsweise einer Flugmaschine, angeschlossen werden kann. Von der Kurbelwelle wird die Anschluß- oder Antriebswelle i i (Abb. a) mittels Zahnräder angetrieben. Als Beispiel ist eine Pumpe gewählt, bei der die Räder zweier Einzelpumpen auf derselben Welle 15 angeordnet sind. Die eine Pumpe, beispielsweise die in der Abb. i links angeordnete Pumpe, dient zur Förderung des Frischöls und hat seinegeringere Förderleistung als die in der Abb. i rechts liegende Pumpe, die zur Förderung des Rücklauföls dient. Da die Rücklaufölpumpe mehr fördert als die Frischölpumpe, so wird mit Sicherheit erreicht, daß die Flugmaschine nicht mit Öl überschwemmt wird.In the drawing, the pump is shown from the outside in Fig. I, in Fig. A in a vertical section and in Fig. 3 in a horizontal section. The pump is a multiple gear pump that can be connected directly to the housing, for example a flying machine. The connecting or drive shaft ii (Fig. A) is driven by the crankshaft by means of gear wheels. As an example, a pump is selected, in which the wheels of two individual pumps are arranged on the same shaft 1. 5 One pump, for example the one on the left in Fig. I, serves to deliver the fresh oil and has a lower delivery rate than the pump on the right in Fig. I, which is used to deliver the return oil. Since the return oil pump delivers more than the fresh oil pump, it is ensured with certainty that the flying machine is not flooded with oil.

In Abb. a ist i i die Anschlußwelle, die in das Gehäuse 12 der Zahnradpumpe hineinragt und an ihrem freien Ende die Schnecke 13 trägt. Die Schnecke greift in das Schneckenrad 14. ein, das auf der Welle 15 der Ölpumpe befestigt ist.In Fig. A i i is the connecting shaft that goes into the housing 12 of the gear pump protrudes and carries the screw 13 at its free end. The snail engages in the worm wheel 14, which is mounted on the shaft 15 of the oil pump.

Wie sich aus Abb. 3 ergibt, ist auf die beiden Enden der Welle 15 je eile Zahnrad aufgesetzt. Da's Zahnrad 16 von geringer Breite gehört zu der Frischölpumpe, das Zahnrad 17 von größerer Breite, aber gleichem Durchmesser, gehört der Rücklaufölpumpe an. Das Zahnrad 16 arbeitet mit dem Zahnrad 161, das Zahnrad i;# mit dem Zahnrad 171 zusammen. Die Räume, in denen die beiden Zahnradpaare zusammen arbeiten, werden nach außen durch die Deckel 18 und 19 abgeschlossen, die öldicht an das Gehäuse 1a geschraubt werden.As can be seen from Fig. 3, there is a 15 on both ends of the shaft each rush gear put on. Since the gear wheel 16 of small width belongs to the fresh oil pump, the gear 17 of greater width but of the same diameter belongs to the return oil pump at. The gear 16 works with the gear 161, the gear i; # with the gear 171 together. The spaces in which the two pairs of gears work together will be closed to the outside by the covers 18 and 19, which are oil-tight to the housing 1a screwed.

In der Z@vischenwand zwischen Getrieberaum und der einen Pumpenseite ist eine Öffnung 2:l angeordnet (vgI. Abb. a). Durch diese Öffnung kann Öl aus dem Pumpenraum in den Getrieberaum austreten, der sich infolgedessen mit Öl anfüllt, so daß das Getriebe und Lager gut geölt werden. Durch diese Öffnung kann ferner Öl mit einer Handpumpe eingeführt werden. Zu diesem Zweck ist am Boden des Getriebegehäuses ein Rückschlagventil z 1 angeordnet, an das bei 2z die Zuführungsleitung angeschlossen werden kann. Der Weg, den das von Hand eingeführte Zusatzöl nimmt, ist auf der Abb. i durch einen Pfeil dargestellt.In the intermediate wall between the gear compartment and one side of the pump an opening 2: 1 is arranged (see Fig. a). This opening allows oil from the The pump chamber can escape into the gear housing, which as a result fills up with oil, so that the gearbox and bearings are well oiled. This opening can also Oil can be introduced with a hand pump. For this purpose is at the bottom of the gear housing a check valve z 1 is arranged to which the supply line is connected at 2z can be. The route taken by the additional oil introduced by hand is shown in Fig. i represented by an arrow.
