Abstract
Wielostopniowe uszczelnienie ochronne z ciecza magnetyczna dla lozyska tocznego zlozone z dwóch magnesów trwalych spolaryzowanych osiowo, dwóch wielokrawedziowych nabiegunników, cieczy magnetycznej i pokrywy, charakteryzuje sie tym, ze jeden magnes (4) osadzony jest w obudowie (2) i przylega z jednej strony do zewnetrznego pierscienia lozyska (3), a z drugiej strony do nabiegunnika (6) równiez osadzonego w obudowie (2), z wystepami uszczelniajacymi wykonanymi na jego wewnetrznej powierzchni walcowej, natomiast drugi magnes (5) osadzony jest na wale (1) i przylega z jednej strony do wewnetrznego pierscienia lozyska (3), a z drugiej strony do nabiegunnika (7) w postaci ksztaltowej tulei kolnierzowej równiez osadzonej na wale (1), która na zewnetrznej powierzchni walcowej ma wystepy uszczelniajace, zas na powierzchni bocznej kolnierza ma wykonane wneki (7a), które z wystepami (9a) wykonanymi na bocznej powierzchni pokrywy (9), przymocowanej do obudowy (2) tworza uszczelnienie labiryntowe osiowe, przy czym magnes (4) jest usytuowany w ukladzie biegunów N-S, a magnes (5) w ukladzie biegunów S-N wzgledem lozyska tocznego (3) lub odwrotnie, zas ciecz magnetyczna (8) znajduje sie w pierscieniowych szczelinach (?), utworzonych pomiedzy wystepami uszczelniajacymi nabiegunnika nieruchomego (6) i nabiegunnika ruchomego (7). W warunkach eksploatacji uszczelnienia wedlug wynalazku, ciecz magnetyczna jest utrzymywana silami pola magnetycznego w szczelinach (?).Multi-stage magnetic liquid seal for rolling bearing composed of two axially polarized permanent magnets, two multi-edge poles, magnetic fluid and cover, characterized by one magnet (4) embedded in the housing (2) and adheres on one side to the outer bearing ring (3), and on the other hand to the pole piece (6) also embedded in the housing (2), with sealing projections made on its inner cylindrical surface, while the second magnet (5) is mounted on the shaft (1) and adheres on one side to the inner ring of the bearing (3), and on the other hand to the pole piece (7) in the form of a shaped flange sleeve also mounted on the shaft (1), which has sealing protrusions on the outer cylindrical surface, and on the lateral surface of the flange have recesses (7a), which with protrusions (9a) made on the side surface of the cover (9) attached to the housing (2) form a labi seal axial, whereby the magnet (4) is located in the NS pole system, and the magnet (5) in the SN pole system relative to the rolling bearing (3) or vice versa, while the magnetic fluid (8) is located in the ring gaps (?) formed between the sealing lugs of the fixed pole piece (6) and the movable pole piece (7). Under the operating conditions of the seal of the invention, the magnetic fluid is held by magnetic field forces in the gaps (?).
