Abstract

Offenbart ist eine Zahnradmaschine mit einem Gehäuse (2) zum Aufnehmen zweier miteinander kämmender Zahnräder (10,12). Diese sind axial mit Axialflächen (30,32,34,36) zwischen Gehäuse aufgenommen Lagerkörpern (26, 28) und radial mit jeweils einer in den Lagerkörpern aufgenommenen Lagerwelle (8, 16) gleitend gelagert. Im Betrieb der Zahnradmaschine treten hydraulische und mechanische Kräfte auf, wobei eine Axialkraftkomponente dieser Kräfte jeweils auf die Zahnräder in eine gleiche Axialrichtung wirkt. Zum Entgegenwirken dieser Axialkraftkomponente ist ein Druckfeld zwischen zumindest einer in Wirkrichtung der Axialkraftkomponente liegenden Axialfläche eines Zahnrads und dem an die zumindest eine Axialfläche angrenzenden Lagerkörper vorgesehen.
