Abstract

l'invention concerne un ensemble de paliers. Cet ensemble comprend deux organes rotatifs, radialement interne et externe respectivement, deux paliers rotatifs aménagés chacun radialement entre lesdits organes et ayant chacun un chemin de roulement interne et un chemin de roulement externe, ledit organe interne et le chemin de roulement interne de l'un des paliers rotatifs étant relativement fixe en direction radiale, ledit organe externe et le chemin de roulement externe de ce palier rotatif étant relativement mobile en direction radiale, des moyens définissant un premier palier à film hydrodynamique entre ledit organe externe et le chemin de roulement externe de ce palier rotatif, ledit organe externe et le chemin de roulement externe de l'autre palier rotatif étant relativement fixes en direction radiale, ledit organe interne et le chemin de roulement interne de l'autre palier rotatif étant relativement mobiles en direction radiale, et des moyens définissant un second palier à film hydrodynamique entre ledit organe interne et le chemin de roulement interne de l'autre palier rotatif.
