Abstract

Die Erfindung bezieht sich auf ein Förderaggregat, insbesondere eine Innenzahnradpumpe (10), mit einem Hohlrad (14) und einem Zahnrad (16). Das Hohlrad (14) und das Zahnrad (16) kämmen miteinander, wobei das Zahnrad (16) an einer Antriebswelle (15) aufgenommen ist, die in einer Exzentrizität (37) zur Achse des Hohlrades (14) verläuft. Sowohl das Hohlrad (14) als auch das Zahnrad (16) sind in einem Gehäuse (11) aufgenommen. Das Gehäuse (11) ist zweiteilig ausgebildet und umfasst ein spielfrei in einem Trägergehäuse (12) gelagertes Pumpengehäuse (13).

The invention relates to a delivery unit, in particular an internal gear pump (10), with a ring gear (14) and a gear (16). The ring gear (14) and the gear (16) mesh with each other, wherein the gear (16) on a drive shaft (15) is received, which extends in an eccentricity (37) to the axis of the ring gear (14). Both the ring gear (14) and the gear (16) are accommodated in a housing (11). The housing (11) is formed in two parts and includes a backlash in a support housing (12) mounted pump housing (13).
