Abstract

Es wird ein aus Kunststoff bestehendes Zahnrad für eine Zahnradpumpe beschrieben, dessen Radkörper (20) eine Außen- oder Innenverzahnung aufweist. Um das Gewicht dieses Zahnrades möglichst klein zu halten, weisen dessen Zähne (26) wenigstens einen, zumindest von einer Zahnstirnseite aus zugänglichen Hohlraum (32) auf. Um beim Einsatz von Zahnradpumpen mit solchen Zahnrädern zur Förderung und Druckbeaufschlagung von Motorenöl in Kraftfahrzeugmotoren durch die Hohlräume (32) Planschverluste zu vermeiden, sind diese verschlossen oder mit einem temperatur- und medienbeständigen Füllmaterial (66) ausgeschäumt.
