Abstract

Przedmiot zgłoszenia stanowią kompaktowe uszczelnienia z cieczą magnetyczną zawierające magnes trwały w kształcie pierścienia spolaryzowany w kierunku osiowym, do powierzchni czołowych którego przylegają nabiegunniki w kształcie tarczy z otworem, a ciecz magnetyczna jest w pierścieniowych szczelinach pomiędzy zakończeniami nabiegunników a zewnętrzną powierzchnią tulei, które z magnesem trwałym tworzą główny obwód magnetyczny, charakteryzujące się tym, że magnes trwały (1) jest kompozytowym magnesem trwałym i całość jest w zestawionych ze sobą: od strony zewnętrznego obwodu pierścieniowego magnesu trwałego (1) zewnętrznej obudowy (6) o przekroju poprzecznym w kształcie litery „L”, od strony wewnętrznego obwodu tulei (4) wewnętrznej osłony (7) o przekroju poprzecznym w kształcie litery „L”. Tuleja (4) ma kołnierz (8), który zazębiony jest z wybraniem (9) w promieniowej części (10) zewnętrznej obudowy (6). Przedmiot zgłoszenia stanowi również metoda wytwarzania uszczelnień.The subject of the application are compact seals with magnetic liquid containing a permanent magnet in the shape of a ring, polarized in the axial direction, to the front surfaces of which pole pieces in the shape of a disc with a hole adhere, and the magnetic liquid is in the annular gaps between the ends of the pole pieces and the outer surface of the sleeve, which with the permanent magnet form the main magnetic circuit, characterized by the fact that the permanent magnet (1) is a composite permanent magnet and the whole is assembled together: from the external circumference of the ring permanent magnet (1) from the external casing (6) with an "L"-shaped cross-section ", from the side of the inner circumference of the sleeve (4) of the inner cover (7) with an "L"-shaped cross-section. The sleeve (4) has a collar (8) which engages with a recess (9) in the radial part (10) of the outer housing (6). The subject of the application is also a method of producing seals.
