Title:

SUPERCONDUCTING BEARING

Document Type and Number:

WIPO Patent Application WO/1993/016294

Kind Code:

A1

Abstract:

A superconducting bearing comprises a rotating member A and a fixed member B, one of which is provided with a superconducting member (5) while the other is provided with a magnet (8). The superconducting member (5) includes a superconductor (4) for floating the magnet (8) and a support (3) for supporting the superconductor (4). The magnet (8) includes a ring-like magnet (11) which is coaxial with the axis of the rotary member A, and the ring-like magnet (11) and the superconductor member (5) are so disposed as to face each other with a gap between them. A magnetic flux diffusion member (13) is disposed on the surface of the ring-like magnet (11) opposed to the superconductor (5). The ring-like magnet (11) comprises two ring-like magnets (11A and 11B) having mutually different diameters, and the ring-like magnets (11A and 11B) are magnetized so that the directions of magnetic fluxes face slantingly with one another.
