Abstract
Hybrydowe uszczelnienie ochronne z cieczą magnetyczną dla łożyska tocznego, zawierające pokrywę, tulejkę kołnierzową, magnes trwały spolaryzowany osiowo, nabiegunnik i ciecz magnetyczną, charakteryzuje się tym, że tulejka kołnierzowa (4) osadzona na wale (1) ma kołnierz (4a), skierowany w stronę obudowy (2) i przylega do wewnętrznego pierścienia łożyska tocznego (3), a na obu bocznych powierzchniach kołnierza (4a), wykonane są występy uszczelniające, zaś w wytoczeniu pokrywy (5), osadzony jest magnes trwały (6) i nabiegunnik (7). Kołnierz (4a) tulei (4) umieszczony jest z luzem w komorze utworzonej przez pokrywę (5), magnes trwały (6) i nabiegunnik (7). Ciecz magnetyczna (8) znajduje się w szczelinach osiowych, utworzonych pomiędzy występami uszczelniającymi na kołnierzu (4a) tulei (4), a powierzchnią boczną nabiegunnika (7) i wewnętrzną boczną powierzchnią ścianki pokrywy (5).A magnetic fluid seal for a rolling bearing, comprising a cover, a flange bushing, an axially polarized permanent magnet, a pole piece and a magnetic fluid, characterized by the fact that the flange bushing (4) mounted on the shaft (1) has a flange (4a) facing the housing side (2) and adheres to the inner ring of the rolling bearing (3), and on both side flange surfaces (4a), sealing protrusions are made, and in the groove of the cover (5), a permanent magnet (6) and a pole piece (7) are mounted ). The collar (4a) of the sleeve (4) is placed loosely in the chamber formed by the cover (5), permanent magnet (6) and the pole piece (7). The magnetic fluid (8) is located in the axial gaps formed between the sealing projections on the collar (4a) of the sleeve (4) and the side surface of the pole piece (7) and the inner side surface of the cover wall (5).
