<p>A permanent magnetic levitating bearing and an assembly including the same are disclosed. The permanent magnetic levitating bearing includes: an inner ring (1) which is a permanent magnet; an outer ring (2) inside which the inner ring (1) is provided, wherein the thickness of the inner ring (1) in the axial direction is less than that of the outer ring (2), and the outer diameter of the inner ring (1) is less than the inner diameter of the outer ring (2); a first radial permanent magnet (3) fixed on the outer ring (2), wherein the first radial permanent magnet (3) and the inner ring (1) magnetically attract each other in the radial direction; and a plurality of axial permanent magnets (4), which are fixed on the outer ring (2) and respectively positioned on both sides in the axial direction of the inner ring (1), so that the inner ring (1) is in a force balance state in the axial direction. The permanent magnetic levitating bearing and the assembly according to the invention have relatively simple structures.</p> |
