Abstract

Offenbart ist eine hydraulische Zahnradmaschine, die ein Gehäuse (2) zum Aufnehmen zweier miteinander kämmender und in Lagerbuchsen gelagerter Zahnräder (10,12) hat. Das Gehäuse (2) ist stirnseitig jeweils mit Gehäusedeckeln (4,6) verschlossen. Bei der Zahnradmaschine ist dabei ein Dichtungselement (38) vorgesehen, das von einem Stützelement (40) gestützt ist. Das Stützelement (40) hat abschnittsweise in Längserstreckung zumindest einen verminderten Querschnitt zur lokalen Verringerung der mechanischen Steifigkeit.
