Abstract

Die Erfindung betrifft eine Innenzahnradpumpe (1). Zu einer hydrodynamischen Schmierung schlägt die Erfindung Keilspalte (24) zwischen Axialscheiben (16) und einem Hohlrad (2) und einem Ritzel der Innenzahnradpumpe und/oder Bohrungen (25) durch die Axialscheiben (16) vor, die mit einem Saugbereich (8) der Innenzahnradpumpe (1) kommunizieren und bei einem Drehantrieb des Hohlrads (2) und des Ritzels die Ausbildung eines Schmierfilms zwischen den Axialscheiben (16) und dem Hohlrad (2) und dem Ritzel vergleichbar einer hydrodynamischen Schmierung eines Axial-Gleitlagers ausbilden.
