Abstract

Hybrydowe uszczelnienie z cieczą ferromagnetyczną dla wału obrotowego, charakteryzuje się tym, że kołnierz (3a) tulei nieruchomej (3) umocowanej w obudowie (2) skierowany jest w stronę wału (1), a kołnierz (4a) tulei ruchomej (4) osadzonej na wale (1) skierowany jest w stronę obudowy (2), zaś pomiędzy kołnierzami (3a i 4a) obu tulei (3 i 4), położonymi w ich środkowej części występuje luz osiowy i promieniowy. Ponadto po zewnętrznych stronach obu kołnierzy (3a i 4a) usytuowane są pary magnesów trwałych (5 i 6), przy czym magnesy (5) umocowane są w tulei nieruchomej (3), a magnesy (6) umocowane są w tulei ruchomej (4), zaś bieguny magnesów (5) umocowanych w tulei nieruchomej (3) i bieguny magnesów (6) umocowanych w tulei ruchomej (4) ustawione są względem siebie w układzie N-S i S-N. Ciecz ferromagnetyczna (7) znajduje się w pierścieniowych szczelinach ? utworzonych pomiędzy biegunami N i S obu par magnesów (5 i 6).A hybrid seal with a ferromagnetic fluid for a rotary shaft is characterized by the fact that the flange (3a) of the fixed sleeve (3) fixed in the housing (2) faces the shaft (1), and the flange (4a) of the movable sleeve (4) mounted on shaft (1) is directed towards the housing (2), and between the flanges (3a and 4a) of both sleeves (3 and 4), located in their central part, there is axial and radial clearance. In addition, on the outer sides of both flanges (3a and 4a) there are pairs of permanent magnets (5 and 6), where the magnets (5) are mounted in a fixed sleeve (3), and the magnets (6) are mounted in a movable sleeve (4) , and the poles of the magnets (5) fixed in the fixed sleeve (3) and the poles of the magnets (6) fixed in the movable sleeve (4) are set relative to each other in the NS and SN system. The ferromagnetic liquid (7) is in the annular fissures? formed between the N and S poles of both pairs of magnets (5 and 6).
