Abstract

Przepust wału obrotowego z uszczelnieniem ferromagnetycznym charakteryzuje się tym, że tuleja kołnierzowa nieruchoma (4), osadzona w obudowie (2) ma kołnierz (4a) skierowany w stronę wału (1), a tuleja kołnierzowa ruchoma (5), osadzona na wale (1), ma kołnierz (5a) skierowany w stronę obudowy (2), zaś pomiędzy obu kołnierzami (4a, 5a) występuje luz, a w komorach powstałych pomiędzy tulejami kołnierzowymi, ruchomą (4) i nieruchomą (5), i ich kołnierzami (4a, 5a) z jednej strony do kołnierza (4a) tulei kołnierzowej nieruchomej (4) przylega pierścień nośny nieruchomy (9), w którym osadzone są walcowe magnesy trwałe spolaryzowane osiowo (10), a w wytoczeniach tego pierścienia (9) umieszczone są wielokrawędziowe nabiegunniki nieruchome (11), zaś z drugiej strony do kołnierza (5a) tulei kołnierzowej ruchomej (5) przylega pierścień nośny ruchomy (6), w którym osadzone są walcowe magnesy trwałe spolaryzowane osiowo (7), a w wytoczeniach tego pierścienia (6) umieszczone są wielokrawędziowe nabiegunniki ruchome (8), przy czym ciecz ferromagnetyczna (12) znajduje się w pierścieniowych szczelinach, utworzonych pomiędzy występami uszczelniającymi nabiegunników ruchomych (8), a wewnętrzną powierzchnią walcową tulei nieruchomej (4) oraz w szczelinach pierścieniowych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników nieruchomych (11), a zewnętrzną powierzchnią walcową tulei kołnierzowej ruchomej (5).A rotary shaft bushing with a ferromagnetic seal is characterized in that the fixed flange sleeve (4), mounted in the housing (2) has a flange (4a) facing the shaft (1), and the movable sleeve sleeve (5), mounted on the shaft (1) ), has a flange (5a) directed towards the housing (2), and between both flanges (4a, 5a) there is play, and in the chambers formed between flange, movable (4) and immovable (5) sleeves, and their flanges (4a, 5a) on one side a fixed support ring (9) adheres to the flange (4a) of the fixed flange sleeve (4), in which cylindrical permanent magnets with axial polarization (10) are mounted, and in the grooves of this ring (9) fixed fixed edge pole pieces (9) 11), while on the other hand a movable support ring (6) adheres to the flange (5a) of the movable flange sleeve (5) in which axially polarized cylindrical permanent magnets (7) are mounted, and in the grooves of this ring (6) are placed multi-edge movable pole pieces (8), the ferromagnetic fluid (12) being in annular gaps formed between sealing protrusions of movable pole pieces (8) and the inner cylindrical surface of the fixed sleeve (4) and in annular gaps between protrusions sealing of multi-edge fixed pole pieces (11) and the outer cylindrical surface of the movable flange sleeve (5).
