Abstract

Винахід належить до підшипника кочення, оснащеного змащувальною масляною плівкою. Підшипник кочення турбомашини для формування опори обертання першого вала (4) відносно другого вала (6) має: множину елементів (12) кочення, встановлених між внутрішньою кільцевою обоймою (14), установленою на другому валу, й зовнішньою кільцевою обоймою (16), установленою на першому валу, масляну плівку (18), формовану на рівні кільцевої поверхні контакту між зовнішньою обоймою і вказаним першим валом і обмежену з боків ущільнювальними кільцями (20, 22), принаймні один живильний канал (34), що проходить наскрізь через внутрішню обойму, і принаймні один додатковий канал (38), що проходить наскрізь через внутрішню обойму, Згідно з винаходом, зовнішня обойма оснащена кільцевим фланцем (42), що утворює радіальний виступ, повернений усередину кільцевого простору. Фланець оснащений принаймні одним подавальним каналом (40), що починається по суті навпроти згаданого додаткового каналу й закінчується на рівні зазначеної масляної плівки. Винахід забезпечує створення достатньо високого тиску масляної плівки.
