Abstract

Zahnradmaschine (Pumpe oder Motor) mit zwei hydraulisch parallel geschalteten, axial zueinander angeordneten, durch eine Zwischenplatte (30) voneinander getrennten Zahnradpaaren (24 und 25) mit im Ausseneingriff oder Inneneingriff ohne oder nahezu ohne Flankenspiel kämmenden geradverzahnten oder schrägverzahnten Zahnrädern (28, 29 und 26, 27), deren Zahnradwellen (16, 21) drehbar gelagert sind in im Gehäuse angeordneten Lagerkörpern (12, 13, 17, 18) oder in im Gehäuse und/oder Gehäusedeckel angeordneten Lagerbuchsen (14, 15, 19, 20) dadurch gekennzeichnet, dass die Verzahnung der zwei auf einer Zahnradwelle (16, 21) angeordneten Zahnräder (27, 29 und 26, 28) in Radmitte betrachtet ein Viertel Zahnteilung zueinander in Umfangsrichtung versetzt ist. Gear machine (pump or motor) with two hydraulic parallel, axially arranged, separated from each other by an intermediate plate (30) Gear pairs (24 and 25) with external or internal engagement without or almost without backlash straight-toothed or helical-toothed gears (28, 29 and 26, 27) whose gear shafts (16, 21) are rotatably mounted are in bearing bodies (12, 13, 17, 18) arranged in the housing or arranged in the housing and / or housing cover Bearing bushes (14, 15, 19, 20) characterized in that the teeth of the two on a gear shaft (16, 21) arranged gears (27, 29 and 26, 28) in the center of the wheel looks at a quarter tooth pitch to each other in the circumferential direction is offset.
