Abstract
Poprzeczne łożyskowanie magnetyczne charakteryzuje się tym, że kołnierz (3a) tulei kołnierzowej nieruchomej (3) osadzonej w obudowie (2) i kołnierz (4a) tulei kołnierzowej ruchomej (4) osadzonej na wale (1), usytuowane są naprzeciw siebie, a w każdej z dwóch komór, powstałych po obu stronach kołnierzy (3a, 4a), pomiędzy wewnętrznymi walcowymi powierzchniami tulei kołnierzowej nieruchomej (3) i zewnętrznymi walcowymi powierzchniami tulei kołnierzowej ruchomej (4) umieszczone są po dwie pary, magnesów trwałych (5, 6 i 9, 10), przedzielonych niemagnetycznymi przekładkami (7, 8), przy czym magnesy trwałe (5, 9) - osadzone w tulei kołnierzowej nieruchomej (3) skierowane są ramionami w stronę wału (1), a magnesy trwałe (6, 10) - osadzone w tulei kołnierzowej ruchomej (4) skierowane są ramionami w stronę obudowy (2), a ponadto, pary magnesów trwałych (5, 6) umieszczone przy kołnierzach (3a, 4a), ustawione są naprzeciwko siebie biegunami jednoimiennymi: S-S i N-N, pomiędzy którymi występują pierścieniowe szczeliny powietrzne (a), zaś pary magnesów trwałych (9, 10), znajdujące się po stronach zewnętrznych tulei kołnierzowych (3, 4) są położone naprzeciwko siebie i ustawione biegunami różnoimiennymi: N-S i S-N, pomiędzy którymi występują pierścieniowe szczeliny (δ), w których znajduje się ciecz ferromagnetyczna (11).Transverse magnetic bearing is characterized by the fact that the flange (3a) of the fixed flange sleeve (3) mounted in the housing (2) and the flange (4a) of the movable flange sleeve (4) mounted on the shaft (1) are located opposite each other, and in each two chambers created on both sides of the flanges (3a, 4a), two pairs of permanent magnets (5, 6 and 9, 10) are placed between the internal cylindrical surfaces of the fixed flange sleeve (3) and the external cylindrical surfaces of the movable flange sleeve (4). ), separated by non-magnetic spacers (7, 8), with the permanent magnets (5, 9) - embedded in the fixed flange sleeve (3) with their arms directed towards the shaft (1), and the permanent magnets (6, 10) - embedded in movable flange sleeve (4) have their arms directed towards the housing (2), and in addition, the pairs of permanent magnets (5, 6) located at the flanges (3a, 4a) are set opposite each other with the same poles: S-S and N-N, between which there are annular air gaps (a), and the pairs of permanent magnets (9, 10), located on the outer sides of the flange sleeves (3, 4), are located opposite each other and arranged with opposite poles: N-S and S-N, between which there are annular gaps (δ) , which contains a ferromagnetic liquid (11).
