PROBLEM TO BE SOLVED: To smoothly rotate a rotor made from a heavy-weight material at a high-speed revolution, relating to a bearing structure for a rotational mechanism, and to provide a mounting method and a device for the mechanism. SOLUTION: The bearing structure for a rotational mechanism is configured, such that the peripheral surfaces of a rotor section 1 and a fixing section 2 that holds the rotation of the rotor section are made to oppose each other, interposing a specified gap G which has the same concentricity as with the rotor section and the fixing section; a field-developing section 3 is formed on either of the peripheral surfaces, and a superconducting section 4 is formed at another peripheral surface; and a field H existing in the gap G is made uniform in the direction of periphery a of the rotor section 1, but is made nonuniform in the direction of the axis z. |
