Abstract

Uszczelnienie odśrodkowe z cieczą magnetyczną dla wału wysokoobrotowego, zawiera tuleję kołnierzową, magnesy trwałe spolaryzowane osiowo, wielokrawędziowe nabiegunniki i ciecz magnetyczną, w którym tuleja kołnierzowa (4) osadzona jest na wale (1), a do obu powierzchni bocznych kołnierza (4a) przylegają biegunami jednoimiennymi magnesy trwałe (5) oraz wielokrawędziowe nabiegunniki (6), umocowane na zewnętrznych, walcowych powierzchniach tulei (4), przy czym wielokrawędziowe nabiegunniki (6) wyposażone są w występy uszczelniające wykonane na ich powierzchniach bocznych, a także tuleja kołnierzowa (4) na obu jej końcach wyposażona jest w występy uszczelniające wykonane na jej zewnętrznych, powierzchniach walcowych, zaś ciecz magnetyczna (7) znajduje się w szczelinach osiowych (?a) pomiędzy występami uszczelniającymi nabiegunników (6), a bocznymi powierzchniami wytoczeń w elementach obudowy (2, 3) oraz w szczelinach promieniowych (?r) pomiędzy występami uszczelniającymi tulei kołnierzowej (4), a wewnętrznymi, cylindrycznymi powierzchniami w elementach obudowy (2, 3).A centrifugal seal with a magnetic fluid for a high-speed shaft, includes a flange sleeve, axially polarized permanent magnets, multi-edge pole shoes and a magnetic fluid in which the flange sleeve (4) is mounted on the shaft (1) and the flange (4a) adjoins to both side surfaces of the flange same-name permanent magnets (5) and multi-edge pole pieces (6), mounted on the outer cylindrical surfaces of the sleeves (4), where the multi-edge pole pieces (6) are equipped with sealing protrusions made on their side surfaces, as well as the flange sleeve (4) on both its ends are equipped with sealing protrusions made on its external cylindrical surfaces, while the magnetic fluid (7) is located in the axial gaps (? a) between the sealing protrusions of the pole pieces (6), and the side surfaces of the grooves in the housing elements (2, 3 ) and in radial gaps (? r) between the protrusions and sealing collar sleeves (4), and internal cylindrical surfaces in the housing components (2, 3).
