A hydrodynamic bearing to support and guide a rotating machine shaft is disclosed. This bearing comprises, in the bore of a bearing body, an independent cartridge, designed to form the internal functional set of the bearing, said cartridge consisting of thin, curved foils fixed with respect to one another with overlapping parts, so as to make an independent unit having, firstly, an internal floating surface adapted to being placed around the shaft and to conditioning, during the rotation of the shaft, the formation of a fluid film between the shaft and the internal surface and, secondly, a peripheral external surface with a diameter corresponding to that of the bore of the bearing body. It further has means to immobilize the cartridge inside the bore in rotation and in internal translation. Furthermore, the external surface of the cartridge is surrounded with a flexible foil, fixed by one of its ends on an external generatrix of the cartridge, the other end being free. |
