A vertical cross-sectional view of this type of superconducting rotor is shown in FIG. 3, and its structure will be explained. Cylindrical room temperature damper 1
One of the openings is hermetically connected to the flanged solid shaft 2a at point a, and the other is hermetically connected to the flanged hollow shaft 2b at point b. A superconducting coil, which will be described later, and other components are built in the space surrounded by these three parts.
a, is connected to the hollow shaft 2b at points C and d. A heat exchanger 5 is provided in the middle of the torque tube 4 to remove conductive heat entering the superconducting coil 3 from room temperature to extremely low temperature. A low-temperature damper 6 whose both ends are connected to a heat exchanger 5 is provided on the outer circumferential side of the coil, and a space 7 is maintained at a high vacuum and is insulated. The refrigerant supply/discharge mechanism section 8 is provided in the hollow cylindrical shaft 2b, and has a refrigerant supply system to the coil section, and the refrigerant that has done effective cooling work in the coil section is further removed by the heat exchanger 5. Pipes 8a such as a return system for discharging to the outside and a current supply system to the coil are assembled. This supply/discharge mechanism part 8 is completely assembled before installing the hollow cylindrical shaft 2b, and then the hollow cylindrical shaft 2b is assembled.
A commonly used method is to assemble the parts by inserting them. At this time, a support piece 9 is interposed between the hollow cylindrical shaft 2b and the supply/discharge mechanism section 8, and by heating the hollow cylindrical shaft 2b and shrink-fitting it, it is possible to prevent gaps from forming between each member. are doing.

た。 However, according to this method, the hollow cylindrical shaft 2b
When inserting the supply/discharge mechanism section 8, an external force corresponding to the shrinkage fit may be applied to the supply/discharge mechanism section 8, which may cause damage, and even if the supply/discharge mechanism section 8 is inserted safely without any damage, the rotational force including the supply/discharge mechanism section 8 may be damaged. If a problem such as a vacuum break occurs in the piping inside the device, when attempting to pull out the hollow cylindrical shaft 2b for inspection or repair, the support piece 9 will tighten and fit, making it impossible to pull out the supply/discharge mechanism section 8. However, there was a drawback that if it was pulled out forcibly, there was a risk of damaging the supply/discharge mechanism piping.
