Abstract
Wynalazek rozwiazuje problem uszczelnienia w budowie maszyn i urzadzen, wymagajacych duzej pewnosci dzialania. Uszczelnienie ochronne z ciecza magnetyczna dla lozyska tocznego, które zawiera pokrywe, tuleje kolnierzowa, magnesy trwale spolaryzowane osiowo, wielokrawedziowe nabiegunniki i ciecz magnetyczna polega na tym, ze w wytoczeniu pokrywy (8) przymocowanej do obudowy (2), osadzony jest magnes trwaly (9) wraz z wielokrawedziowym nabiegunnikiem nieruchomym (10), a na wale (1) osadzona jest tuleja kolnierzowa (4), której kolnierz umieszczony jest z luzem osiowym wzgledem nabiegunnika nieruchomego (10) i z luzem promieniowym wzgledem wewnetrznej powierzchni walcowej gniazda pokrywy (8), na walcowej powierzchni tulei kolnierzowej (4) od strony lozyska (3), osadzony jest drugi magnes trwaly (5) wraz z wielokrawedziowym nabiegunnikiem ruchomym (6), natomiast ciecz magnetyczna (7) znajduje sie w pierscieniowych szczelinach, utworzonych pomiedzy wystepami uszczelniajacymi nabiegunnika nieruchomego (10), a zewnetrzna powierzchnia walcowa tulei kolnierzowej (4) oraz w pierscieniowych szczelinach, utworzonych pomiedzy wystepami uszczelniajacymi nabiegunnika ruchomego (6), a wewnetrzna powierzchnia walcowa gniazda pokrywy (8).The invention solves the problem of sealing in the construction of machines and devices that require high reliability. Magnetic fluid protective seal for rolling bearing, which includes a cover, flange bushes, axially permanently polarized magnets, multi-edge pole pieces and magnetic fluid consists in the permanent magnet (9) being embedded in the extrusion of the cover (8) attached to the housing (9) ) together with the fixed edge pole (10), and a flange sleeve (4) is mounted on the shaft (1), the collar of which is positioned with axial clearance relative to the fixed pole (10) and with radial clearance relative to the inner cylindrical surface of the cover seat (8), on the cylindrical flange sleeve surface (4) from the bearing side (3), a second permanent magnet (5) is mounted together with the multi-edge movable pole piece (6), while the magnetic fluid (7) is located in the ring gaps formed between the sealing lips of the fixed pole piece (10), and the outer cylindrical surface of the flange sleeve (4) and in the ring gaps, formed between the sealing protrusions of the movable pole piece (6) and the inner cylindrical surface of the cover seat (8).
