Title:
MANUFACTURE OF SUPERCONDUCTING ROTOR
Document Type and Number:
Japanese Patent JPS6223364
Kind Code:
A
Abstract:

PURPOSE: To stabilize quality and improve output, by using no wedges, and by fixing superconducting windings firmly with keep plates in grooves.

CONSTITUTION: So far as an external cylinder 1 for the cold shield of a superconducting rotor is concerned, the one end is fixed on a driving side shaft 2a, and the other end is fixed on a counter-driving side shaft 2b. Besides, on the both shafts 2, the external cylinder 1 and the torque tube 3 of a co-axial internal cylinder are fixed, and inside the tube 3, a superconducting rotor winding 5 is fixed via a supporting cylinder 4. Besides, outside the supporting cylinder 4, a plurality of grooves 7 are arranged, and superconducting windings 8 are fixed in the respective grooves 7. Between the torque tube 3 and the windings 8, the keep plates 11 of insulating substance are fitted on the opening sections of the grooves 7. By winding up the keep plates 11 with heat-shrinking tapes and heating and shrinking them, the keep plates 11 are tightened on the superconducting windings 8, to be molded. Then, the superconducting windings 8 can be kept by the specified face pressure of the keep plates 11 against an electromagnetic force and a centrifugal force.
