Abstract
Hybrydowe łożysko wzdłużno-poprzeczne wałka, w którym tulejka kołnierzowa (3) osadzona na czopie (1a) wałka (1), ma występy uszczelniające wykonane na jej zewnętrznej powierzchni walcowej, zaś do obu powierzchni bocznych kołnierza (3a) tulejki kołnierzowej (3) przylegają pierścieniowe magnesy trwałe (4,5) spolaryzowane promieniowo. Magnes trwały (4) ustawiony jest prostopadle w układzie biegunów S-N, a magnes trwały (5) ustawiony jest prostopadle w układzie biegunów N-S, względem powierzchni wałka (1). We wnęce (1b) wykonanej na powierzchni czołowej czopa (1a) wałka (1) i we wnęce (2b) wykonanej na powierzchni czołowej gniazda (2a) obudowy (2), umocowane są walcowe magnesy trwałe (7,8) spolaryzowane osiowo ustawione względem siebie biegunami jednoimiennymi N. Ciecz magnetyczna (6) znajduje się w szczelinach promieniowych (δ<sub>r</sub>) pomiędzy występami uszczelniającymi usytuowanymi na zewnętrznej walcowej powierzchni tulejki kołnierzowej (3), a wewnętrzną cylindryczną powierzchnią gniazda (2a) obudowy (2) oraz w szczelinach promieniowych (δ<sub>r</sub>) pomiędzy występami uszczelniającymi wielokrawędziowego nabiegunnika (12), a powierzchnią wałka (1).Hybrid longitudinal-transverse bearing of the shaft, in which the flange sleeve (3) mounted on the journal (1a) of the shaft (1) has sealing protrusions made on its outer cylindrical surface, and both side surfaces of the flange (3a) of the flange sleeve (3) are adjacent annular permanent magnets (4,5) radially polarized. The permanent magnet (4) is set perpendicularly in the S-N pole system, and the permanent magnet (5) is set perpendicularly in the N-S pole system, relative to the surface of the shaft (1). In the recess (1b) made on the front surface of the journal (1a) of the shaft (1) and in the recess (2b) made on the front surface of the socket (2a) of the housing (2), cylindrical permanent magnets (7,8) are fixed, axially polarized with like poles N. The magnetic liquid (6) is located in the radial gaps (δ<sub>r</sub>) between the sealing protrusions located on the outer cylindrical surface of the flange sleeve (3) and the inner cylindrical surface of the socket (2a) of the housing ( 2) and in the radial gaps (δ<sub>r</sub>) between the sealing protrusions of the multi-edge pole piece (12) and the surface of the shaft (1).
