Abstract

Przepust wału obrotowego uszczelniony cieczą ferromagnetyczną, charakteryzuje się tym, że w komorze obudowy (2) pomiędzy łożyskami tocznymi (3), umieszczona jest tuleja kołnierzowa symetryczna (4) osadzona w obudowie (2) lub na wale obrotowym (1), a do bocznych powierzchni kołnierza (4a) tulei kołnierzowej symetrycznej (4) przylegają obustronnie magnesy trwałe (6) osadzone na wewnętrznych lub zewnętrznych powierzchniach walcowych tulei kołnierzowej symetrycznej (4), natomiast na wale obrotowym (1) lub w obudowie (2) umocowane są tuleje kołnierzowe niesymetryczne (5) z kołnierzami (5a) usytuowanymi po stronie powierzchni czołowych łożysk tocznych (3), a do wewnętrznych bocznych powierzchni kołnierzy (5a) tulei kołnierzowych niesymetrycznych (5) przylegają magnesy trwałe (7) osadzone na zewnętrznych lub wewnętrznych powierzchniach walcowych tulei kołnierzowych niesymetrycznych (5). Ciecz ferromagnetyczna (8) znajduje się w szczelinach pierścieniowych δ, utworzonych pomiędzy końcami ramion magnesów trwałych (6, 7) stanowiącymi bieguny N i S, a odpowiednimi wewnętrznymi lub zewnętrznymi powierzchniami walcowymi tulei kołnierzowej symetrycznej (4) i tulei kołnierzowej niesymetrycznej (5).The rotating shaft bushing sealed with ferromagnetic liquid is characterized by the fact that in the housing chamber (2) between the rolling bearings (3) there is a symmetrical flange sleeve (4) mounted in the housing (2) or on the rotating shaft (1), and to the side the flange surface (4a) of the symmetrical flange sleeve (4) is adhered on both sides by permanent magnets (6) mounted on the internal or external cylindrical surfaces of the symmetrical flange sleeve (4), while asymmetrical flange sleeves are mounted on the rotating shaft (1) or in the housing (2). (5) with flanges (5a) located on the side of the front surfaces of the rolling bearings (3), and permanent magnets (7) mounted on the external or internal cylindrical surfaces of the asymmetrical flange sleeves adhere to the inner side surfaces of the flanges (5a) of the asymmetrical flange sleeves (5). (5). The ferromagnetic liquid (8) is located in the annular gaps δ, formed between the ends of the arms of permanent magnets (6, 7) constituting the N and S poles, and the appropriate internal or external cylindrical surfaces of the symmetrical flange sleeve (4) and the asymmetrical flange sleeve (5).
