Abstract
Wynalazek rozwiazuje problem lozyskowania szybkoobrotowych walków w przyrzadach precyzyjnych i drobnych mechanizmach. Lozyskowanie charakteryzuje sie tym, ze w komorze utworzonej pomiedzy walkiem (1), a gniazdem obudowy(2) umieszczona jest panewka porowata (3) z pierscieniowymi gniazdami wykonanymi na jej zewnetrznej powierzchni walcowej, w których osadzone sa segmentowe magnesy trwale (4) spolaryzowane promieniowo, z biegunami (N) skierowanymi w strone gniazda obudowy (2) i biegunami (S) skierowanymi w strone powierzchni walka (1), a w górnej czesci gniazda obudowy (2) umieszczony jest wielokrawedziowy nabiegunnik (5), zas ciecz magnetyczna (6) znajduje sie na powierzchni styku panewki (3) z walkiem (1) oraz w szczelinach pierscieniowych (?) utworzonych pomiedzy wystepami uszczelniajacymi nabiegunnika (5), a powierzchnia walka (1).The invention solves the problem of bearing high-speed rollers in precision instruments and small mechanisms. The bearing is characterized by the fact that the chamber formed between the shaft (1) and the housing seat (2) has a porous cup (3) with ring seats made on its external cylindrical surface in which segment permanent magnets (4) are radially polarized , with the poles (N) facing the housing seats (2) and the poles (S) facing the shaft surface (1), and in the upper part of the housing seat (2) there is a multi-edge pole piece (5), and magnetic fluid (6) located on the contact surface of the bearing (3) with the shaft (1) and in the ring gaps (?) formed between the sealing protrusions of the pole piece (5) and the surface of the shaft (1).
