(EN) ELECTRICALLY DRIVEN MACHINE, IN PARTICULAR A PUMP

Abstract
(DE)
Die Erfindung betrifft eine elektrisch angetriebene Maschine, insbesondere Pumpe, mit einem Elektromotor, der einen auf einer Rotorwelle (7) angeordneten Rotor (4) umfasst, der in einem Stator drehbar ist, der mit einem Statorgehäusekörper (16) aus einem Kunststoffmaterial (17) umspritzt ist, und mit zwei Lagern (13), um die Rotorwelle (7) mit dem Rotor axial und radial zu lagern. Um die elektrisch angetriebene Maschine konstruktiv, insbesondere im Hinblick auf eine unerwünscht lange Toleranzkette bei der Rotorwellenlagerung, zu verbessern, ist die Rotorwelle (7) mit einem Radial-Axial-Gleitlager (20) radial und axial sowohl in Richtung eines rotierenden Maschinenelements (8) als auch in der entgegengesetzten axialen Richtung gelagert.
(EN)
The invention relates to an electrically driven machine, in particular a pump, having an electric motor, which comprises a rotor (4) that is arranged on a rotor shaft (7) and is rotatable in a stator, which stator is overmolded with a stator housing body (16) made of a plastics material (17), and having two bearings (13) in order to axially and radially support the rotor shaft (7) together with the rotor. In order to improve the design of the electrically driven machine, in particular in respect of an undesirably long tolerance chain in the bearing arrangement for the rotor shaft, the rotor shaft (7) is supported radially and axially by a radial-axial sliding bearing (20) in the direction of a rotating machine element (8) and also in the opposite axial direction.
(FR)
L’invention concerne une machine à entraînement électrique, notamment une pompe. La machine à entraînement électrique comporte un moteur électrique qui comprend un rotor (4) disposé sur un arbre de rotor (7), lequel rotor peut tourner dans un stator surmoulé avec un corps de carter de stator (16) en matière plastique (17). La machine comporte en outre deux paliers (13) permettant de monter axialement et radialement l’arbre de rotor (7) avec le rotor. L’objet de l’invention est l’amélioration de la machine à entraînement électrique, en ce qui concerne la construction, en particulier en ce qui concerne une chaîne de tolérances indésirablement longue lors du montage de l’arbre de rotor. Pour ce faire, l’arbre de rotor (7) est monté radialement et axialement avec un palier lisse radial-axial (20), aussi bien dans le sens d’un élément de machine (8) rotatif que dans le sens axial opposé.
