Abstract

Hybrydowe łożysko wzdłużno-promieniowe złożone z wałka, obudowy, magnesów trwałych spolaryzowanych osiowo, magnesów trwałych spolaryzowanych promieniowo, wielokrawędziowych nabiegunników o przekroju poprzecznym dwuteowym i cieczy magnetycznej charakteryzuje się tym, że w komorze dławnicowej obudowy (2) umieszczony jest co najmniej jeden lub więcej wielokrawędziowych nabiegunników (3) o przekroju poprzecznym dwuteowym, przedzielonych niemagnetycznymi przekładkami (9), zaś w szczelinach pierścieniowych, utworzonych pomiędzy występami uszczelniającymi wielokrawędziowych nabiegunników (3), a wałkiem (1) znajduje się ciecz magnetyczna (5) przy czym, we wnęce wykonanej na powierzchni czołowej czopa wałka (1) oraz we wnęce wykonanej na dnie gniazda w obudowie (2) umieszczone są naprzeciwko siebie walcowe magnesy trwałe (6, 7) spolaryzowane osiowo i ustawione względem siebie biegunami jednoimiennymi.Hybrid radial thrust bearing consisting of a shaft, housing, axially polarized permanent magnets, radially polarized permanent magnets, multi-edge pole pieces with I-cross section and magnetic fluid is characterized by the fact that in the stuffing box of the housing (2) at least one or more multi-edge pole pieces (3) with an I-cross section, separated by non-magnetic spacers (9), and in the annular gaps formed between the sealing lips of the multi-edge pole pieces (3) and the shaft (1) there is a magnetic fluid (5), in the cavity made on on the front surface of the shaft journal (1) and in the recess made at the bottom of the housing (2), cylindrical permanent magnets (6, 7), axially polarized and aligned with each other with identical poles, are positioned opposite to each other.
