ABSTRACT:
A bearing for turbojet engines, placed between a high pressure journal and a low pressure journal is in the form of a roller bearing with rollers, and an inner bushing and an outer bushing, all contained in a box mounted on the low pressure journal. A nut maintains the bushing on the high pressure journal and has an annular recess arranged to receive oil through an inlet dividing it by means of vanes, through axial holes on the bushing, toward the roller bearing for its lubrication and cooling, and through radial holes, by means of the centrifugal effect, to an annular collector formed in the box. The collector has a plurality of stabilizing vanes and its radial height determines the feed pressure, by means of calibrated holes in the box, of a film of oil in an axial space constituted between the bushing and the box, in order to assure therein the damping of vibrations.
