Abstract
Die Erfindung betrifft eine Zahnradpumpe mit zwei ineinandergreifenden Zahnrädern (9, 10) zwischen einem Saugraum und einem Druckraum, wobei beide Zahnräder über mit den Zahnrädern verbundene Lagerachsen (11, 12) gelagert sind. Erfindungsgemäß sind die Zahnräder und die Lagerachsen je aus dem gleichen Material als homogenes Werkstück einstückig hergestellt. Dies ermöglicht einen vereinfachten Aufbau der Zahnradpumpe bei gleichzeitig guten Laufeigenschaften. Bevorzugt werden die Zahnräder und die Lagerachsen aus Kunststoff hergestellt.
