SUPERCONDUCTIVITY ROTOR HAVING IMPROVED TORQUE TUBE

摘要

A superconductive rotor with an improved torque tube is provided to simplify the internal structure of the superconductive rotor and a generator without a separate device for coping with contraction by absorbing the contraction due to the temperature change of a rotation shaft direction in the torque tube. A superconductive rotor with an improved torque tube includes a superconductive field coil unit(10), a field coil supporting unit(20), a first torque tube(60), a second torque tube(80), an inner casing(40), and an outer casing(50). The superconductive field coil unit is wound by a superconductive wire. The field coil supporting unit supports the field coil unit. The torque tube is placed at both ends of the field coil supporting unit, and transmits rotating force from the field coil unit to the outside. The inner casing includes the field coil unit and the field coil supporting unit. The outer casing includes the inner casing and the torque tube. The torque tubes placed at both ends of the field coil supporting unit have different structures. The first torque tube is arranged at one end of the inner casing, has a cylinder shape with a plurality of coupling holes along the circumference, and is coupled through a coupling member(70). The second torque tube is arranged at the other end of the inner casing, is a laminate of plates and a plurality of ring-shaped members, and is coupled through a coupling member.
