Abstract
Ślizgowe łożysko oporowe smarowane cieczą magnetyczną, zawierające wałek, podstawę, panewkę porowatą, magnesy trwałe spolaryzowane osiowo, nabiegunnik wielokrawędziowy, tulejkę kołnierzową i ciecz magnetyczną, charakteryzuje się tym, że wałek (1) zakończony jest stopniowanym czopem walcowym, który składa się z części dolnej czopa walcowego (1a), części górnej czopa walcowego (1b) oraz tarczy (1c), usytuowanej nad czopem walcowym. Na tarczy (1c) i części górnej czopa walcowego (1b) osadzony jest wielokrawędziowy nabiegunnik (6), zaś na powierzchni walcowej dolnej części czopa walcowego (1a) osadzona jest panewka porowata (3) nasycona cieczą magnetyczną (8). Jeden magnes trwały (4) umieszczony jest w pierścieniowej komorze utworzonej pomiędzy wytoczeniem w wielokrawędziowym nabiegunniku (6), a dolną powierzchnią czołową tarczy (1c). Drugi magnes trwały (5) umieszczony jest w pierścieniowej komorze utworzonej pomiędzy wytoczeniem w tulejce kołnierzowej (7), a zewnętrzną czołową powierzchnią podstawy (2). Ciecz magnetyczna (8) znajduje się na stożkowej powierzchni styku panewki porowatej (3) z gniazdem stożkowym w podstawie (2) oraz w pierścieniowych szczelinach (δ), utworzonych pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika (6), a gładką górną powierzchnią czołową tulejki kołnierzowej (7).A sliding thrust bearing lubricated by a magnetic liquid, containing a shaft, a base, a porous bearing, axially polarized permanent magnets, a multi-edge pole piece, a flange sleeve and a magnetic liquid, is characterized by the fact that the shaft (1) is ended with a stepped cylindrical journal, which consists of a lower part the cylindrical journal (1a), the upper part of the cylindrical journal (1b) and the disc (1c), located above the cylindrical journal. A multi-edge pole piece (6) is mounted on the disc (1c) and the upper part of the cylindrical journal (1b), and on the cylindrical surface of the lower part of the cylindrical journal (1a) there is a porous bushing (3) saturated with magnetic liquid (8). One permanent magnet (4) is placed in an annular chamber formed between the recess in the multi-edge pole piece (6) and the lower face of the disc (1c). The second permanent magnet (5) is placed in an annular chamber formed between the recess in the flange sleeve (7) and the outer front surface of the base (2). The magnetic fluid (8) is located on the conical contact surface of the porous bushing (3) with the conical seat in the base (2) and in the annular gaps (δ) formed between the sealing projections of the multi-edge pole piece (6) and the smooth upper face of the flange sleeve ( 7).
