Abstract

Przedmiotem wynalazku jest uszczelnienie ochronne łożyska tocznego w środowisku cieczy magnetycznej, znajdujące zastosowanie przy łożyskowaniu wałów obrotowych maszyn i urządzeń, wymagających dużej pewności działania. Uszczelnienie ochronne ma tulejkę kołnierzową (4) z kołnierzem (4a) skierowanym w stronę wału (1) umocowana jest w obudowie (2), a wielokrawędziowy nabiegunnik w postaci tulejki kołnierzowej (5) z kołnierzem (5a) skierowanym w stronę obudowy (2) osadzony jest na wale (1) i posiada występy uszczelniające usytuowane na zewnętrznej walcowej powierzchni kołnierza (5a), a w obustronnych gniazdach powstałych pomiędzy wewnętrznymi cylindrycznymi powierzchniami tulejki kołnierzowej (4) i zewnętrznymi walcowymi powierzchniami tulejki kołnierzowej (5) oraz powierzchniami bocznymi kołnierza (4a) tulejki i powierzchniami bocznymi kołnierza (5a) umieszczone są magnesy trwałe (6, 7).The subject of the invention is a protective seal for a rolling bearing in an environment of magnetic fluid, used in the bearing of rotating shafts in machines and devices that require high operational reliability. The protective seal has a flange bushing (4) with the flange (4a) facing the shaft (1) is mounted in the housing (2), and the multi-edge pole piece in the form of a flanged sleeve (5) with the flange (5a) facing the housing (2) it is mounted on the shaft (1) and has sealing protrusions located on the outer cylindrical surface of the flange (5a), and in the double-sided seats formed between the inner cylindrical surfaces of the collar sleeve (4) and the outer cylindrical surfaces of the collar sleeve (5) and the side surfaces of the collar (4a) the sleeve and the side surfaces of the flange (5a) there are permanent magnets (6, 7).
