ABSTRACT:
A flexible coupling for connecting pairs of concentric rotor elements in the rotor of a superconducting generator. Various combinations of flexible couplings, each of which is disposed normally to the rotor axis, are used at one or both ends of the superconducting rotor to connect the inner and outer rotors and to connect the inner rotor to a concentric insulating shield. The flexible coupling utilizes a relatively thin ring. When used to connect the inner rotor to the insulating shield the ring may be constructed of a material that retains flexibility at temperatures down to at least about 100.degree. K. The ring may be laminated to increase flexibility and may be made up of joined segmental portions. Securing devices are annularly distributed about the ring. The securing devices are spaced apart a sufficient distance to permit deflections of the ring in an axial direction. The rings are dimensioned to provide radially and torsionally rigid connections between the rotor elements, maintaining their concentricity, while permitting relative axial movements between the rotor elements to accommodate relative thermal contractions and expansions of the rotor elements during cool-down and warm-up of the superconducting rotor.
