Abstract

Uszczelnienie z cieczą magnetyczną dla łożyska tocznego charakteryzuje się tym, że w kołnierzu tulejki kołnierzowej (4) osadzonej na wale (1) i w przegrodzie pokrywy (5) przymocowanej do obudowy (2) wykonane są otwory rozmieszczone równomiernie na obwodzie, w których umieszczone są walcowe magnesy trwałe (6, 7). Natomiast do powierzchni bocznych kołnierza tulejki kołnierzowej (4) przylegają wielokrawędziowe nabiegunniki ruchome (8), a do przegrody pokrywy (5) przylegają wielokrawędziowe nabiegunniki nieruchome (9). Ciecz magnetyczna (10) znajduje się w pierścieniowych szczelinach (?) utworzonych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników ruchomych (8), a odpowiednimi wewnętrznymi powierzchniami walcowymi pokrywy (5) oraz w szczelinach pierścieniowych (?) pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników nieruchomych (9) i odpowiednimi zewnętrznymi powierzchniami walcowymi tulejki kołnierzowej (4).The magnetic fluid seal for a rolling bearing is characterized by the fact that in the flange of the flange sleeve (4) mounted on the shaft (1) and in the partition of the cover (5) attached to the housing (2), holes are distributed evenly distributed along the circumference, in which cylindrical roller bearings permanent magnets (6, 7). On the other hand, the lateral surfaces of the flange bushing (4) adjoin the multi-edge movable pole pieces (8), and the cover partition (5) adjoins the fixed edge pole pieces (9). The magnetic fluid (10) is located in the annular gaps (?) Formed between the sealing protrusions of the multi-edge movable rockers (8) and the corresponding inner cylindrical surfaces of the cover (5) and in the annular gaps (?) Between the sealing protrusions of the fixed edge pole pieces (9) and corresponding outer cylindrical surfaces of the flange sleeve (4).
