Title
(DE) PUMPE ZUR FÖRDERUNG EINES FLUIDS
(EN) PUMP FOR CONVEYING A FLUID
(FR) POMPE POUR LE TRANSPORT D'UN FLUIDE
Abstract
(DE) Die Erfindung betrifft eine Pumpe zur Förderung eines Fluids mit - einem Pumpengehäuse (2), in dem wenigstens ein Pumpenelement (3) um dessen Pumpenelementlängsachse (4) drehbar gelagert ist, - einem Rotor (6) eines Antriebsmotors (7), der um eine Rotorlängsachse (9) drehbar in einem Antriebsgehäuse (8) sitzt, - wobei der Rotor (6) eine Rotorwelle (5) besitzt, deren erster Wellenzapfen (10) mit dem wenigstens einen Pumpenelement (3) drehmomentübertragbar gekoppelt ist, - und die Rotorwelle (5) mit einem zweiten Wellenzapfen (11) im Antriebsgehäuse (8) wälzgelagert ist, wobei der erste Wellenzapfen (10) zu dessen Radiallagerung mittels eines Gleitlagers (12) gelagert ist, welches im Pumpengehäuse (2) angeordnet ist.
(EN) The invention relates to a pump for conveying a fluid, comprising: - a pump housing (2) in which at least one pump element (3) is mounted so as to be rotatable about its pump element longitudinal axis (4); - a rotor (6) of a drive motor (7), which rotor is positioned in a drive housing (8) so as to be rotatable about a rotor longitudinal axis (9); wherein the rotor (6) has a rotor shaft (5), the first shaft journal (10) of which is coupled to the at least one pump element (3) in such a way that torque can be transmitted; wherein a second shaft journal (11) of the rotor shaft (5) is mounted in the drive housing (8) by means of a roller bearing; and wherein, for the radial support of the first shaft journal, the first shaft journal (10) is mounted by means of a plain bearing (12) arranged in the pump housing (2).
(FR) L'invention concerne une pompe pour le transport d'un fluide, comprenant: - un carter de pompe (2) dans lequel au moins un élément de pompe (3) est monté de manière à pouvoir tourner autour de son axe longitudinal d'élément de pompe (4); - un rotor (6) d'un moteur d'entraînement (7), ledit rotor étant positionné dans un carter d'entraînement (8) de manière à pouvoir tourner autour d'un axe longitudinal de rotor (9); le rotor (6) présente un arbre de rotor (5), dont le premier tourillon d'arbre (10) est accouplé à l'au moins un élément de pompe (3) de telle sorte que le couple puisse être transmis; un second tourillon d'arbre (11) de l'arbre de rotor (5) étant monté dans le carter d'entraînement (8) au moyen d'un roulement à rouleaux; et, pour le support radial du premier tourillon d'arbre, le premier tourillon d'arbre (10) est monté au moyen d'un palier lisse (12) disposé dans le carter de pompe (2).
