Die Erfindung betrifft einen Zahnradmotor, bei welchem die Zahnräder auf Wälzlagern gelagert sind, wobei auf der Welle jeweils ein Distanzstück angeordnet ist und so die Leckage reduziert wird.The method involves fastening an outer ring of a roller bearing in the stator housing and screwing an inner ring of the roller bearing and a rotor with a predetermined torque. The outer ring of another roller bearing is fastened in the stator housing and the inner ring of the latter roller bearing and the rotor are screwed. The screw connection is tightened such that the rotor is centered in the axial direction. An independent claim is also included for a gear motor with a stator.
