Abstract
Przedmiotem zgłoszenia jest wielostopniowe uszczelnienie dla łożyska tocznego w krążniku przenośnika taśmowego, stosowanego zwłaszcza do transportu różnego rodzaju materiałów sypkich, kawałkowych lub ładunków jednostkowych. Uszczelnienie to charakteryzuje się tym, że w piaście krążnika (2), pomiędzy pierścieniem labiryntowym ruchomym (9) a pierścieniem zewnętrznym łożyska tocznego (3) umieszczone są kolejno, przekładka magnetyczna (8), magnes trwały (5), nabiegunnik ruchomy (6), a na osi krążnika (1) pomiędzy pierścieniem labiryntowym nieruchomym (10) a pierścieniem wewnętrznym łożyska tocznego (3) osadzony jest wielokrawędziowy nabiegunnik nieruchomy (4) w kształcie tulejki kołnierzowej, której kołnierz (4a) posiadający występy uszczelniające na bocznych powierzchniach, umieszczony jest w komorze powstałej pomiędzy przekładką magnetyczną (8), magnesem trwałym (5) i nabiegunnikiem ruchomym (6), zaś ciecz magnetyczna (7) znajduje się w pierścieniowych szczelinach (δ), utworzonych pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika nieruchomego (4) a powierzchnią boczną przekładki magnetycznej (8) oraz w szczelinach pierścieniowych (δ), powstałych pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika nieruchomego (4) a powierzchnią boczną nabiegunnika ruchomego (6).The subject of the application is a multi-stage seal for a rolling bearing in the roller of a belt conveyor, used especially for transporting various types of bulk materials, piece materials or unit loads. This seal is characterized by the fact that in the roller hub (2), between the movable labyrinth ring (9) and the outer ring of the rolling bearing (3), there are, in turn, a magnetic spacer (8), a permanent magnet (5), and a movable pole piece (6). , and on the roller axis (1) between the fixed labyrinth ring (10) and the inner ring of the rolling bearing (3), there is a multi-edge fixed pole piece (4) in the shape of a flange sleeve, the collar of which (4a) having sealing projections on the side surfaces, is placed in the chamber created between the magnetic spacer (8), the permanent magnet (5) and the movable pole piece (6), and the magnetic liquid (7) is located in the annular gaps (δ) formed between the sealing projections of the multi-edge stationary pole piece (4) and the side surface magnetic spacer (8) and in the annular gaps (δ) formed between the sealing projections of the multi-edge fixed pole piece (4) and the side surface of the movable pole piece (6).
