Abstract
La présente invention concerne les dispositifs de rééquilibrage automatique de systèmes tournants dont l'équilibrage initial risque de se modifier dans le temps et d'engendrer des vibrations. Le dispositif selon l'invention est caractérisé en ce que la pression d'un fluide, dans le palier lui-même ou dans un manchon indépendant du palier, réglée par le balourd sur le système tournant, agit dans des chambres 7 à volume variable disposées autour d'une masse unique d'équilibrage 4 coulissant dans un plan radial dans une cavité concentrique au système tournant. La présente invention s'applique à tous systèmes tournants dont la géométrie risque de se modifier dans le temps et en particulier aux rotors de moteurs électriques et à des moto-compresseurs.The present invention relates to devices for automatic rebalancing of rotating systems, the initial balancing of which is liable to change over time and to generate vibrations. The device according to the invention is characterized in that the pressure of a fluid, in the bearing itself or in a sleeve independent of the bearing, adjusted by the unbalance on the rotating system, acts in chambers 7 with variable volume arranged around a single balancing mass 4 sliding in a radial plane in a cavity concentric with the rotating system. The present invention applies to all rotating systems, the geometry of which risks changing over time and in particular to the rotors of electric motors and to motor-compressors.
