Abstract
Uszczelnienie odśrodkowe z cieczą magnetyczną dla wału wysokoobrotowego charakteryzuje się tym, że na bocznych powierzchniach kołnierza (3a) tulei (3) osadzonej na wale (1), wykonane są gniazda, w których umieszczone są wielokrawędziowe nabiegunniki (5) o przekroju prostokątnym z występami uszczelniającymi, usytuowanymi na ich zewnętrznych powierzchniach bocznych, a w ściance kołnierza (3a) tulei (3) położonej pomiędzy wielokrawędziowymi nabiegunnikami (5), umocowane są w otworach, równomiernie rozłożone walcowe magnesy trwałe (4). Kołnierz (3a) tulei (3) wraz z magnesami trwałymi (4) i wielokrawędziowymi nabiegunnikami (5) umieszczony jest z luzem promieniowym i osiowym w gnieździe obudowy (2), zamkniętej pokrywą (7). Ciecz magnetyczna (6) znajduje się w szczelinach osiowych (?a), utworzonych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników (5), a powierzchniami bocznymi gniazda obudowy (2) i pokrywy (7) lub w szczelinie promieniowej (?r), utworzonej wokół kołnierza (3a) tulei (3) na jego obwodzie.A centrifugal seal with a magnetic liquid for a high-speed shaft is characterized by the fact that on the lateral surfaces of the flange (3a) of the sleeve (3) mounted on the shaft (1), sockets are made, in which rectangular pole pieces (5) with rectangular cross-section are placed , located on their outer side surfaces, and in the flange wall (3a) of the sleeve (3) located between the multi-edge pole pieces (5), are fixed in the holes, evenly distributed cylindrical permanent magnets (4). The collar (3a) of the sleeve (3) together with permanent magnets (4) and multi-edge pole pieces (5) are placed with radial and axial play in the housing socket (2), closed with the cover (7). The magnetic fluid (6) is located in the axial slots (? A) formed between the sealing lips of the multi-edge pole pieces (5) and the side surfaces of the housing seat (2) and the cover (7) or in the radial gap (? R) formed around the flange (3a) the sleeve (3) around its circumference.
