Abstract: front page image
(EN)In a bearing device that includes: a pair of bearings (11, 12) that is disposed on a turbine shaft (4) of a supercharger (1); a case (22) that is a separate component from the pair of bearings and to which outer races (lib, 12b) of the bearings are fitted; a bearing housing (5) that is assembled with the case to form an oil-film damper (8); a sleeve (14) that is disposed between inner races (Ha, 12a) of the bearings to maintain a fixed distance (Y) between the inner races in the axial direction; and a spacer (23) that is disposed between the outer races to maintain a fixed distance (X) between the outer races in the axial direction, the outer races are located inward of end faces (22a, 22b) of the case in the axial direction, and the outer races are unconstrained to the outside in the axial direction.
(FR)Un dispositif de support comprend : une paire de roulements (11, 12) disposés sur un arbre de turbine (4) d’un compresseur (1) ; un boîtier (22) qui est un composant séparé de la paire de roulements et sur lequel des chemins extérieurs (lib, 12b) des roulements sont installés ; un logement de palier (5) qui est assemblé avec le boîtier pour former un amortisseur à film d’huile (8); un manchon (14) qui est disposé entre les chemins internes (Ha, 12a) des roulements pour maintenir une distance fixe (Y) entre les chemins internes dans le sens axial ; et une entretoise (23) qui est disposée entre les chemins externes pour maintenir une distance fixe (X) entre les chemins externes dans le sens axial, les chemins externes étant situés vers l’intérieur des faces internes (22a, 22b) du boîtier dans le sens axial, et les chemins externes étant non restreints vers l’extérieur dans le sens axial.
