Abstract
Hybrydowe uszczelnienie ochronne dla łożyska tocznego, charakteryzuje się tym, że w komorze utworzonej pomiędzy łożyskiem tocznym (3), czopem wału (1), wewnętrzną powierzchnią cylindryczną gniazda obudowy (2) i pokrywą (11), umieszczone są pierścienie nośne (4) przedzielone magnesem trwałym spolaryzowanym osiowo (7), umocowane w obudowie (2) lub na czopie wału (1), zaś pierścienie nośne (4) są wyposażone w pierścieniowe wnęki (4a), w których osadzone są magnesy trwałe spolaryzowane promieniowo (5, 6). Wielokrawędziowy nabiegunnik (8) w postaci tulejki kołnierzowej, osadzony jest na czopie wału (1) lub w obudowie (2), z kołnierzem (8a) położonym luźno pomiędzy magnesami trwałymi spolaryzowanymi promieniowo (5, 6) oraz magnesem trwałym spolaryzowanym osiowo (7). Ciecz ferromagnetyczna (9) umieszczona jest w szczelinach promieniowych δ, utworzonych pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika (8), wykonanymi na jego zewnętrznych powierzchniach walcowych, a wewnętrznymi powierzchniami cylindrycznymi pierścieni nośnych (4), położonymi po obu stronach kołnierza (8a) wielokrawędziowego nabiegunnika (8) lub w szczelinach promieniowych δ utworzonych pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika (8) wykonanymi na jego wewnętrznych powierzchniach cylindrycznych, a zewnętrznymi powierzchniami walcowymi pierścieni nośnych (4).The hybrid protective seal for a rolling bearing is characterized by the fact that in the chamber formed between the rolling bearing (3), the shaft journal (1), the inner cylindrical surface of the housing seat (2) and the cover (11), support rings (4) separated by axially polarized permanent magnet (7), mounted in the housing (2) or on the shaft journal (1), while the support rings (4) are equipped with annular recesses (4a) in which radially polarized permanent magnets (5, 6) are mounted . A multi-edge pole piece (8) in the form of a collar sleeve, is mounted on the shaft journal (1) or in the housing (2), with the collar (8a) loosely placed between the radially polarized permanent magnets (5, 6) and the axially polarized permanent magnet (7) . The ferromagnetic fluid (9) is placed in the radial gaps δ, formed between the sealing projections of the multi-edge pole piece (8), made on its external cylindrical surfaces, and the internal cylindrical surfaces of the support rings (4), located on both sides of the flange (8a) of the multi-edge pole piece ( 8) or in radial gaps δ formed between the sealing projections of the multi-edge pole piece (8) made on its internal cylindrical surfaces and the external cylindrical surfaces of the support rings (4).
