Abstract[German]
Erfindungsgemäß wird ein elektromechanisch betriebener Spiralverdichter mit einer Orbitallageranordnung (1 ) mit einem Orbitallager (3) zur Lagerung eines eine Verdichterspirale (2) aufweisenden Verdichterrades (17) gegenüber einer Motorwelle (4) vorgeschlagen, wobei ein Federelement (8) axial zwischen dem Orbitallager (3) und dem Verdichterrad (17) angeordnet ist, das Federelement (8) sich am Verdichterrad (17) abstützt, und das Federelement (8) den Innenring (5) zum Außenring (6) axial vorspannen kann, damit im Orbitallager (3) kein axiales Spiel mehr vorhanden ist.[English]
The invention relates to an electromechanically operated scroll compressor having an orbital bearing assembly (1) comprising an orbital bearing (3) for mounting a compressor wheel (17), which has a compressor scroll (2), with respect to a motor shaft (4), wherein: a spring element (8) is located axially between the orbital bearing (3) and the compressor wheel (17); the spring element (8) is supported against the compressor wheel (17); and the spring element (8) can axially preload the inner ring (5) with respect to the outer ring (6) so that there is no longer any axial play in the orbital bearing (3).[French]
L'invention concerne un compresseur à spirale à commande électromécanique ayant un ensemble palier orbital (1) comprenant un palier orbital (3) pour monter une roue de compresseur (17), qui a une spirale de compresseur (2), par rapport à un arbre de moteur (4), dans lequel : un élément ressort (8) est situé axialement entre le palier orbital (3) et la roue de compresseur (17) ; l'élément ressort (8) est supporté contre la roue de compresseur (17) ; et l'élément ressort (8) peut précharger axialement la bague interne (5) par rapport à la bague externe (6) de sorte qu'il n'y ait plus de jeu axial dans le palier orbital (3).
