Abstract
Hybrydowe uszczelnienie ochronne wału zawierające osadzone na wale: korpus, pokrywę, tuleję z występem, nabiegunnik, pierścień gumowy, wkładkę, magnes trwały oraz ciecz magnetyczną, charakteryzuje się tym, że w korpusie (6), umieszczonym nad występem (2a) wykonanym na tulei (2) osadzonej na wale (1) znajduje się warga pierścienia gumowego (10), a pomiędzy wargą pierścienia gumowego (10), a wkładką (3) wykonaną z niemagnetycznego materiału, znajduje się ciecz magnetyczna (4). Od strony wnęki pierścienia gumowego (10) do jego powierzchni bocznej przylega osadzony w korpusie (6) nabiegunnik (5), którego część znajduje się we wnęce pierścienia gumowego (10), zaś wewnętrzna powierzchnia cylindryczna nabiegunnika (5) o najmniejszej wartości średnicy znajduje się nad wargą pierścienia gumowego (10). Magnes trwały (8) spolaryzowany osiowo, z jednej strony przylega powierzchnią boczną do korpusu (6), a z drugiej do pokrywy (7), która ma kształt tarczy i której wewnętrzna powierzchnia cylindryczna tworzy szczelinę powietrzną z zewnętrzną powierzchnią cylindryczną tulei (2).Hybrid protective shaft seal with mounted on the shaft: body, cover, sleeve with a shoulder, pole piece, rubber ring, insert, permanent magnet and magnetic liquid, characterized by the fact that in the body (6), placed over the projection (2a) made on the sleeve (2) mounted on the shaft (1) there is a rubber ring lip (10), and between the rubber ring lip (10) and the insert (3) made of non-magnetic material, there is a magnetic liquid (4). On the side of the cavity of the rubber ring (10), a pole piece (5) embedded in the body (6) is adjacent to its side surface. above the lip of the rubber ring (10). Permanent magnet (8), axially polarized, on one side adheres to the body (6) with its side surface, and on the other side to the cover (7), which has the shape of a disc and whose inner cylindrical surface forms an air gap with the outer cylindrical surface of the sleeve (2).
