Abstract

Hybrydowe uszczelnienie z cieczą magnetyczną dla wałów obrotowych zawiera wielokrawędziowy nabiegunnik, magnesy trwałe spolaryzowane promieniowo, ciecz magnetyczną i pokrywę. Wielokrawędziowy nabiegunnik osadzony na wale (1) jest w kształcie tulei kołnierzowej (3) i na powierzchni walcowej kołnierza (3a) oraz na powierzchni walcowej tulei kołnierzowej (3) ma wykonane występy uszczelniające. We wnęce usytuowanej na wewnętrznej czołowej powierzchni pokrywy (4) przymocowanej do obudowy (2) osadzone są segmentowe magnesy trwałe (5) spolaryzowane promieniowo. Ciecz magnetyczna (6) znajduje się w szczelinach pierścieniowych (?) utworzonych pomiędzy występami uszczelniającymi na kołnierzu (3a), a wewnętrzną górną walcową powierzchnią pokrywy (4) oraz w szczelinach pierścieniowych (5) utworzonych pomiędzy występami uszczelniającymi położonymi na zewnętrznej, walcowej powierzchni tulei kołnierzowej (3), a wewnętrzną dolną powierzchnią walcową pokrywy (4).A hybrid magnetic fluid seal for rotating shafts includes a multi-edge pole piece, radially polarized permanent magnets, a magnetic fluid and a cover. The multi-edge pole piece mounted on the shaft (1) is shaped like a flange sleeve (3) and on the cylindrical surface of the flange (3a) and on the surface of the cylindrical flange sleeve (3) has sealing projections. Radial polarized segment magnets (5) are embedded in the recess located on the inner front surface of the cover (4) attached to the housing (2). The magnetic fluid (6) is located in the annular gaps (?) Formed between the sealing projections on the flange (3a) and the inner top cylindrical surface of the cover (4) and in the annular gaps (5) formed between the sealing projections located on the outer cylindrical surface of the sleeve flange (3) and the inner lower cylindrical surface of the cover (4).
