Document Type and Number:
Japanese Patent JP3302705
Kind Code:
B2
Abstract:
PURPOSE:To provide secure coupling with a normal temperature rotor and a low temperature rotor without looseness by a method wherein dovetail-shaped trenches or protrusions are provided on the inner and outer circumferences of a flexible support which supports a torque tube and has a multilayer laminated structure. CONSTITUTION:A plurality of dovetail-shaped protrusions 11 and 12 are provided on the outer circumference of a cylindrical part formed on the end part of a torque tube 6a and on the inner circumference of a normal temperature damper 1 respectively so as to correspond to each other. A flexible support 7 with which the torque tube 6a is attached to the normal temperature damper 1 flexibly is composed of spoke-shaped thin disc plates laminated together. Dovetail- shaped trenches 13 and 14 which can be mated with the dovetail-shaped protrusions 11 and 12 are provided on the inner and outer circumferences of the flexible support 7 respectively. With this constitution, the inclined bearing planes of the dovetails are securely brought into contact with each other by a radial tensile stress produced in the disc during operation, so that the looseness of a coupling part can be eliminated.
