Title (EN) HOOP FOR A HYDROSTATIC OR HYDRODYNAMIC BEARING, METHOD FOR MOUNTING SUCH A HOOP ON A SHAFT, AND ASSEMBLY FORMED BY SUCH A HOOP AND A SHAFT
(FR) FRETTE POUR PALIER HYDROSTATIQUE OU HYDRODYNAMIQUE, PROCÉDÉ DE MONTAGE D'UNE TELLE FRETTE SUR UN ARBRE, ENSEMBLE FORMÉ D'UNE TELLE FRETTE ET D'UN ARBRE
Abstract:
(EN) The invention relates to a hoop (120) comprising: a cylinder (200) which, so that it can be mounted around a shaft, is formed by multiple parts (202, 203) that are assembled together using assembly means that can produce an assembly without deformation of an external surface of the cylinder; and a ring (300), of which an external surface forms the internal surface of the bearing and which, so that it can be secured to the external wall of the cylinder, is formed by multiple elements (302, 303) that are secured to the cylinder by securing means that can maintain a machining tolerance of the external surface of the ring.
(FR) Une frette (120) comporte : un cylindre (200) qui, pour pouvoir être monté autour de l'arbre, est composé de plusieurs pièces (202, 203) assemblées les unes aux autres par des moyens d'assemblage propres à réaliser un assemblage sans déformation d'une surface extérieure du cylindre; une bague (300) dont une surface extérieure constitue la surface intérieure du palier, et qui, pour pouvoir être fixée à la paroi extérieure du cylindre est composée de plusieurs éléments (302, 303) fixés au cylindre par des moyens de fixation propres à conserver une tolérance d'usinage de ladite surface extérieure de la bague.
