Abstract
Przepust wału z wielostopniowym uszczelnieniem z cieczą magnetyczną, zawierający łożyska toczne, osadzone na wale nabiegunniki, przedzielone magnesami trwałymi spolaryzowanymi osiowo, tulejki oraz ciecz magnetyczną, charakteryzuje się tym, że nabiegunniki (5) osadzone w obudowie (2) przedzielone są trwałym magnesem nieruchomym (4), a tulejki (6) z występami uszczelniającymi usytuowanymi na ich zewnętrznych powierzchniach walcowych, osadzone są na wale (1) i przedzielone drugim trwałym magnesem ruchomym (7), gdzie bieguny trwałego magnesu nieruchomego (4) są ustawione w układzie N-S, a bieguny trwałego magnesu ruchomego (7) w układzie S-N lub w ustawieniu odwrotnym dla każdego z magnesów, zaś kołnierze (6a) tulejek (6) umieszczone są z luzem w wytoczeniach nabiegunników (5) w pobliżu łożysk tocznych (3), gdzie w nabiegunnikach (5) wykonane są zbiorniczki (8) na ciecz magnetyczną (10), połączone promieniowymi kanalikami (9) ze szczelinami roboczymi, przy czym ciecz magnetyczna (10) wypełnia zbiorniczki (8), kanaliki (9) oraz pierścieniowe szczeliny, utworzone pomiędzy występami uszczelniającymi tulejek (6), a wewnętrznymi powierzchniami walcowymi nabiegunników (5).A shaft bushing with a multi-stage magnetic liquid seal, containing rolling bearings, pole shoes mounted on the shaft, separated by axially polarized permanent magnets, sleeves and magnetic fluid, characterized by the fact that the pole shoes (5) embedded in the housing (2) are separated by a permanent stationary magnet ( 4), and the sleeves (6) with sealing projections located on their outer cylindrical surfaces are mounted on the shaft (1) and separated by a second permanent movable magnet (7), where the poles of the permanent fixed magnet (4) are set in the NS system, and permanent moving magnet poles (7) in the MV system or in the reverse setting for each of the magnets, while the flanges (6a) of the sleeves (6) are placed loosely in the grooves of the pole pieces (5) near the rolling bearings (3), where in the pole pieces ( 5) tanks (8) for magnetic fluid (10) are made, connected by radial channels (9) with working slots, The magnetic fluid (10) fills the reservoirs (8), channels (9) and annular gaps formed between the sealing lips of the sleeves (6) and the inner cylindrical surfaces of the pole pieces (5).
