Abstract

Uszczelnienie ochronne z cieczą magnetyczną dla łożyska tocznego charakteryzuje się tym, że ma w wytoczeniu (4a) pokrywy (4) umieszczone wielokrawędziowe nabiegunniki nieruchome (10) z występami uszczelniającymi usytuowane na ich wewnętrznych powierzchniach cylindrycznych, przedzielone magnesem trwałym (11) spolaryzowanym osiowo, a na wale (1) osadzona jest tulejka kołnierzowa (5) z kołnierzem (5a) skierowanym w stronę obudowy (2), zaś na walcowych powierzchniach tulejki kołnierzowej (5) osadzone są magnesy trwałe (6, 7) spolaryzowane promieniowo, przylegające do bocznych powierzchni kołnierza (5a) tulejki kołnierzowej (5).A protective seal with a magnetic liquid for a rolling bearing is characterized by the fact that in the recess (4a) of the cover (4) there are multi-edged stationary pole shoes (10) with sealing lips located on their internal cylindrical surfaces, separated by a permanent magnet (11) polarized axially, and the shaft (1) is fitted with a flange bushing (5) with the flange (5a) facing the housing (2), and permanent magnets (6, 7), radially polarized, adjacent to the side surfaces are mounted on the cylindrical surfaces of the flange bushing (5) flange (5a) of the sleeve (5).
