Abstract

Uszczelnienie ochronne z cieczą magnetyczną, zwłaszcza dla łożyska tocznego, charakteryzuje się tym, że jedna para magnesów trwałych (4, 5) przedzielona niemagnetyczną przekładką (7), osadzona jest w wewnętrznym pierścieniu nośnym (3) i przylega do jego bocznej ścianki prostopadłej do osi wału, a druga para magnesów trwałych (4, 5) przedzielona niemagnetyczną przekładką (7), również umocowana jest w wewnętrznym pierścieniu nośnym (3) i przylega do bocznej ścianki zewnętrznego pierścienia nośnego (2), prostopadłej do osi wału. Magnesy (4), położone po obu stronach kołnierza (1a), nad przekładkami (7) skierowane są biegunami jednoimiennymi N (lub S) do bocznych powierzchni kołnierza (1a) tulejki kołnierzowej (1), a magnesy (5), położone po obu stronach kołnierza (1a), pod przekładkami (7) skierowane są biegunami jednoimiennymi S (lub N) do bocznych powierzchni kołnierza (1a) tulejki (1). Ciecz magnetyczna (6) znajduje się w szczelinach osiowych (?a), utworzonych pomiędzy powierzchniami czołowymi magnesów (4, 5) i przekładek (7), a bocznymi powierzchniami kołnierza (1a) tulejki kołnierzowej (1) oraz w szczelinie promieniowej (?r), utworzonej pomiędzy cylindryczną powierzchnią kołnierza (1a) tulejki kołnierzowej (1), a cylindryczną ścianką wewnętrznego pierścienia nośnego (3).A protective seal with a magnetic liquid, especially for a rolling bearing, is characterized by the fact that one pair of permanent magnets (4, 5) separated by a non-magnetic spacer (7), is embedded in the inner support ring (3) and adheres to its side wall perpendicular to the axis shaft and the other pair of permanent magnets (4, 5) separated by a non-magnetic spacer (7), is also mounted in the inner support ring (3) and adheres to the side wall of the outer support ring (2), perpendicular to the shaft axis. Magnets (4), located on both sides of the flange (1a), above the spacers (7) are directed by identical poles N (or S) to the side surfaces of the flange (1a) of the flange sleeve (1), and the magnets (5) located on both sides of the flange (1a), under the spacers (7) are directed by identical poles S (or N) to the side surfaces of the flange (1a) of the sleeve (1). The magnetic fluid (6) is located in the axial slots (? A) formed between the front surfaces of the magnets (4, 5) and spacers (7), and the lateral flange surfaces (1a) of the flange sleeve (1) and in the radial gap (? R ) formed between the cylindrical surface of the flange (1a) of the flange sleeve (1) and the cylindrical wall of the inner support ring (3).
