Zweckmäßig werden auch die Zahnräder aus Sinterwerkstoff hergestellt. Diese Zahnräder können zur Herabsetzung des Verschleisses einer Wärmebehandlung unterzogen werden. Die Neuerung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt und im nachstehenden im einzelnen anhand der Zeichnung beschrieben.The gears made of sintered material are also expedient manufactured. These gears can be subjected to a heat treatment to reduce wear will. The innovation is shown in the drawing in an exemplary embodiment and in the following described in detail with reference to the drawing.

Die Zahnradpumpe nach Fig. 1 bis 3 besteht aus einem Gehäuse 2 mit einem Deckel 4· und der Zwischenplatte Das Gehäuse 2 enthält die Bohrungen 8, 10 für die Lagerung der Wellen 12, 14, sowie die Bohrung 16 zur Aufnahme der Wellendichtung 18. Außerdem enthält das Gehäuse 2 die Bohrungen 20, 22 für der. Anschluß der Saug- und Druckleitung. Der Deckel 4- enthält ebenfallsThe gear pump according to FIGS. 1 to 3 consists of a housing 2 with a cover 4 · and the intermediate plate. The housing 2 contains the bores 8, 10 for mounting the shafts 12, 14, and the bore 16 for receiving the shaft seal 18. In addition the housing 2 contains the bores 20, 22 for the. Connection of the suction and pressure lines. The cover 4- also contains

die Bohrungen 8, 10 zur Lagerung der Wellen 12, 14·.the bores 8, 10 for mounting the shafts 12, 14 ·.

Die Zwischenplatte 6 enthält die entsprechenden Bohrungen 24, 26 für die Zahnräder 28, 30. Die Teile 2, 4-, 6 sind gegeneinander durch Zylinderstifte 32 fixiert und mittels Schrauben 34· und Sechskantmuttern 36 zusammengehalten. The intermediate plate 6 contains the corresponding bores 24, 26 for the gears 28, 30. The parts 2, 4-, 6 are fixed to one another by cylindrical pins 32 and held together by means of screws 34 and hexagon nuts 36.

Alle in den Teilen 2, 4, 6, 28, 30 liegenden Bohrungen, Verzahnungen und Aussparungen sind in axialer Richtung angeordnet und können somit preßtechnisch mit so großer Genauigkeit hergestellt werden, daß keine Nachbearbeitung erforderlich ist.All bores, teeth and recesses in parts 2, 4, 6, 28, 30 are in the axial direction arranged and can thus be produced by pressing with such great accuracy that no reworking is required.

Lediglich die Stirnflächen der beiden Gehäuseteile 2 und 4 und der Zwischenplatte 6 v/erden zweckmäßig mechanisch nachbearbeitet, um ebene, abdichtende Flächen zu erzielen. Only the end faces of the two housing parts 2 and 4 and the intermediate plate 6 are expediently mechanically grounded reworked to achieve even, sealing surfaces.

Die Funktion der Pumpe ist die gleiche wie bei bekannten Zahnradpumpen oder -motoren mit Zahnrädern im Außeneingriff und unveränderlichem Axialspalt.The function of the pump is the same as in known gear pumps or motors with gear wheels in external engagement and invariable axial gap.

Bei Verwendung entsprechender Sinterwerkstoffe für die Zahnräder lassen sich Pumpen für Betriebsdrücke über 50 kg/cm herstellen.When using appropriate sintered materials for the gears can be used to produce pumps for operating pressures above 50 kg / cm.
