Title:
DAMPER FOR SUPERCONDUCTING ROTOR
Document Type and Number:
Japanese Patent JPH04190673
Kind Code:
A
Abstract:

PURPOSE: To increase the joining area ratio and joining strength between joined members so as to improve the dimensional accuracy by joining a conductive member to a reinforcing member and reinforcing members to each other in solid-phase states and joining the reinforcing members to both end sections of the conductive member.

CONSTITUTION: An intermediate Cu sleeve 11 is metallurgically joined to an outer SUS cylinder 12 and inner SUS cylinder 13 made of austenitic nonmagnetic steel by applying an isotropic pressure to the external surfaces of the cylinders 12 and 13 under a hightemperature condition. Then inner rings 14a and 14b made of austenitic nonmagnetic steel are joined to both ends of the sleeve 11 by applying an isotropic pressure under a high-temperature condition. Therefore, a low- and high-temperature damper which has a large joining area ratio, high joining strength, and high dimensional accuracy at its joined section is obtained and the vibration of the rotor of a superconducting generator can be prevented.
