Abstract

Przepust wału z uszczelnieniem ferromagnetycznym, zawierający tuleję kołnierzową (4), wielokrawędziowe nabiegunniki (5), magnesy trwałe (6, 7, 8 i 9) spolaryzowane osiowo i ciecz ferromagnetyczną (10) charakteryzuje się tym, że w komorze obudowy (2) pomiędzy łożyskami tocznymi (3) umieszczone są: tuleja kołnierzowa (4) osadzona na wale (1) lub w obudowie (2), wielokrawędziowe nabiegunniki (5) umocowane w obudowie (2) lub na wale (1) i dwie pary magnesów trwałych (6, 7, 8 i 9) umieszczone w obudowie (2) i na wale (1), pomiędzy tuleją kołnierzową (4) i wielokrawędziowymi nabiegunnikami (5), a łożyskami tocznymi (3), usytuowane względem powierzchni bocznych pierścieni obu łożysk tocznych (3) biegunami różnoimiennymi N i S. Ciecz ferromagnetyczna (10) znajduje się w pierścieniowych szczelinach (?), pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników (5), a zewnętrznymi lub wewnętrznymi powierzchniami cylindrycznymi tulei kołnierzowej (4).Shaft bushing with a ferromagnetic seal, containing a flange bushing (4), multi-edge pole pieces (5), axial polarized permanent magnets (6, 7, 8 and 9) and a ferromagnetic fluid (10) is characterized in that in the housing chamber (2) between roller bearings (3) are located: a flange sleeve (4) mounted on the shaft (1) or in the housing (2), multi-edge pole pieces (5) mounted in the housing (2) or on the shaft (1) and two pairs of permanent magnets (6 , 7, 8 and 9) located in the housing (2) and on the shaft (1), between the flange sleeve (4) and the multi-edge pole pieces (5) and the rolling bearings (3), located relative to the side surfaces of the rings of both rolling bearings (3) ) with the opposite poles N and S. The ferromagnetic fluid (10) is located in the annular gaps (?), between the sealing lips of the multi-edge pole pieces (5), and the outer or inner cylindrical surfaces of the flanged bushes j (4).
