Description
Bei derartigen Zahnradpumpen kann es vorkommen. daß die Zahnrandseiten
bei besonders ungünstigen Betriebsbedingungeng wie
Es ist bekannt, die Räder in axialbeweglichen Buchsen zu
Diese Nachteile werden nach der Erfindung dadurch vermieden, daß die Gehäusewände mindestens in Ringsonen die den Zahnrädern zugekehrt sind und die Zahnradwollen umschließen, elastisch nachgiebig ausgebildet sind.These disadvantages are avoided according to the invention in that the Housing walls at least in the ring sons Facing gears and the gearwheels enclose, are designed to be resilient.
Ausführungsbeispiele der Erfindung sind in der Zeichnung wiedergegeben.
Sie zeigt in Fig. 1 einen Längsschnitt eines ersten AusEihrungsbei-
Das Gehäuse der Pumpe nach der Anmeldung besteht aus einer Anschlußplatte
lt einer Zwischenplatte 2 und einer Antriebsplatte 30 In den Platten 1 und 3 sind
die Wellen 4 und 5 zweier Zahnräder 6 und 7 gelagert, die Zahnräder laufen in Aussparungen
der Zwischenplatte 2 zwischen den Platten 1 und 3.
In die Bohrungen die als Lager für die Wellen 4 und 5 dienen sind
nahe der als Gleitflächen dienenden Innenflächen 25 und 26 der Platten 1 und 3 verhältnismäßig
schmale und tiefe Ringnuten 27 bis 30 eingestochen. So entstehen zwischen
Die Zahnräder 6 und 7 sind zwischen die Platten 1 und 3 mit
Bei dem Ausführungsbeispiel nach Fig. 2 ist die Pumpe im wesentlichen gleich aufgebaut wiebei dem vorstehend beschriebenen Ausführungsbeispiel ; es sind aber keine Kanäle 33 angeordnet. Der Leckölraum 13 und die Bohrungen 15e. 17, 19 sind durch Kanäle 33, 34 mit einem Sammelraum 35 verbunden, der unter Bildung eines Ventilsitzes 36 an eine den Saugraum 22 mit dem Rohranschluß 21 verbindenden Bohrung 37 grenzt.In the embodiment of FIG. 2, the pump is essentially constructed the same as in the embodiment described above; there are but no channels 33 are arranged. The leakage oil space 13 and the bores 15e. 17, 19 are connected by channels 33, 34 with a collecting space 35, which forms a Valve seat 36 to a bore connecting the suction chamber 22 to the pipe connection 21 37 borders.
Auf diesem Ventilsitz ruht das kegelförmige Ende 38 eines Schließkörpers
39 ? der von einer Druckfeder 40 auf dem Sitz gehalten wird. Das entgegengesetzte
Ende des Schließkörpers ist zu einem Kolben 41 ausgebildet und gleitet in einer
Bohrung 42, welche mit dem Druckraum 23 verbunden ist, also unter Förderdruck steht.
Diese Quernuten'werden von den Zahnlücken überstrichen so lange zwischen
den Zähnen eingeschlossenes Öl unter verhältnismäßig hohem Druck verdrängt wird.
Dieses Öl gelangt durch die Kanäle 43 in die Ringnuten 27. bis 30 und übt dort den
stützenden Zwei-
