Abstract (en)
1. Motor-driven pump set with an impeller arranged on its pump shaft and a torque-secured planetary gearing sitting between the driving motor and said pum shaft, said pump shaft running in a fixed bearing in the pump casing and with said planetary gearing as a loose bearing in the motor-driven pump set, the planetary gearing being journalled in the motor-driven pump set, characterized by the motor-driven pump set being engineered as a submersible motor-driven pump set with an axial impeller (3), by the planetary gearing (5) being engineered as a reduction gear, by a coupling (12) transmitting the bending moments, arranged between pump shaft (4) and output shaft (11) of the planetary gearing (5), and by the planetary gearing (5) shifting axially.
Abstract (de)
Die Erfindung hat ein Tauchmotorpumpenaggregat zum Gegenstand, dessen Pumpenteil mit einem Axialpropeller versehen ist. Zwischen Antriebsmotor (1) und Pumpenwelle (4) ist ein als Untersetzungsgetriebe wirkendes Planetengetriebe (5) drehmomentgesichert und axial verschieblich angeordnet. Die Verbindung zwischen Pumpenwelle (4) und Abtriebswelle (11) des Planetengetriebes (5) erfolgt durch eine Biegemomente übertragende Kupplung (12). Das Planetengetriebe (8) bildet somit das Loslager für die Pumpenwelle (4), welche im Pumpengehäuse (2) in einem Festlager (13, 14) festgelegt ist.
