    摘要： A superconducing bearing device comprising a permanent magnet portion (3) provided on a rotatable member (1), and a superconductor disposed as opposed to the magnet portion (2). The permanent magnet portion (3) is so mounted on the rotatable member (1) that the rotation of the rotatable member does not alter the magnetic flux distribution around the axis of rotation of the member. The superconductor (2) permits penetration of the magnetic flux of the magnet portion thereinto, is spaced apart from the magnet portion (3) by a distance permitting a predetermined quantity of magnetic flux of the magnetic portion (3) to penetrate thereinto, and is disposed at a position not permitting the rotation of the rotatable member (1) to alter the distribution of penetrating magnetic flux.

    摘要： A superconducting bearing device comprises an annular permanent magnet portion 2 disposed concentrically with a rotary body 1 in the form of a vertical shaft, and superconductors 8 opposed to the lower end face of the magnet portion 2 and vertically spaced apart therefrom. The permanent magnet portion 2 comprises a disk 4 fixedly mounted on the rotary body 1, and annular permanent magnets 6a, 6b arranged on the disk 4 at a spacing radially of the rotary body 1. Each of the magnets 6a, 6b has upper and lower ends magnetized to polarities opposite to each other, and the adjacent magnets 6a, 6b are magnetized to polarities opposite to each other at the upper ends, as well as at the lower ends. The radial spacing between the magnets 6a, 6b is optimized in accordance with the radial dimension (width) of the magnets 6a, 6b. This improves the device in load capacity and rigidity and prevents the deflection of axis of the rotary body 1, enabling the bearing device to support the rotary body 1 in a noncontact state with good stability.
