) The tightened portion according to (10) provides uniform surface contact, but the surface contact other than the tightened portion is insufficient, resulting in uneven metal surface contact, which impedes heat conduction. Furthermore, during rotation, the parts between the clamping parts sag, inhibiting metal surface contact, resulting in poor heat transfer, and the heat radiation shield (9) becomes hot, which adversely affects the cryostat (2).

There is one in which the ends of 9) are welded to the protrusions (3a) and (3b). However, in the case of the former, slippage occurs in the press-fit part when rotating at high speed, the heat radiation shield (9) deforms into a drum shape, and the contact surface with the protrusions (3a) and (3b) becomes small, resulting in poor heat transfer. However, there is a risk that support will eventually fall. Further, the latter has disadvantages such as thermal deformation due to welding, resulting in uneven metal surface contact, and the relative deformation between the thermal radiation shield (9) and the torque tube (3) cannot be absorbed.

回転子を提供することを目的とする。The present invention provides a superconducting rotor in which a support structure between a thermal radiation shield and a protruding portion of a torque tube is configured so that uniform metal surface contact is obtained, and the contact surface becomes a uniform metal contact surface even during high-speed rotation. The purpose is to

るようにしたものである。他は同じである。An embodiment of the present invention shown in the drawings will be described below. In FIG. 2, parts having the same functions as those in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted. The difference is that both ends of the thermal radiation shield (9) are attached to ring-shaped protrusions (3a) and (3b), which are provided at opposite positions at a longer distance than the torque tube (3-inch cryostat (2)), by shrink fitting, etc. Press-fit the heat radiation shield (9), and then fit the ring-shaped retainer (13) to the outer periphery of the heat radiation shield (9) by shrink fitting or other means.
9) is arranged so that the metal surface contacts the protrusions (3a) and (3b) uniformly. Everything else is the same.

ない。Next, the effect will be explained. The thermal radiation shield (9) has a protrusion (
3a) and (3b), and press the presser (13) on the outer periphery.
Since the heat radiation shield (9) has been fitted, the protrusion (3a
), (3b) to form a heat radiation seal l'
(9) has uniform metal surface contact with the protrusions (3a) and (3b) and has large frictional resistance sb, thermal radiation shield (9)
The force that prevents movement in the axial direction is strong. Therefore, even if the thermal radiation shield (9) tries to deform into a drum shape during high-speed rotation, the thermal radiation shield (9) and the protrusion (3)
A) and (3b), the contact surface between the heat radiation shield (9) and the torque tube (3) is very small even if it occurs.
The relative deformation between the two is absorbed, and the contact surface remains almost unchanged.

Since heat is efficiently conducted from b) to the torque tube (3) and cooled by uniform metal surface contact, heat radiation to the cryostat (2) is suppressed and reliability is high even when rotating at high speed.

By fitting the presser foot (13) between a) and (3b), deformation of the thermal radiation shield (9) can be prevented and the cooling effect can be improved.
Instead of 13), steel wire may be wrapped and tightened.

果がある。As described above, according to the present invention, in the superconducting rotor, at least both ends of the thermal radiation shield are press-fitted into ring-shaped protrusions provided at opposite positions of the torque tube, and further, a ring-shaped presser is fitted to the outer periphery. As a result, the heat radiation shield comes into uniform metal surface contact with the protrusion, and the frictional resistance is strong, so that the force that prevents the heat radiation shield from moving in the axial direction is strong. Therefore, even during high-speed rotation, deformation of the thermal radiation shield is prevented, and the contact surface between the thermal radiation shield and the protruding part remains almost unchanged, so that the intruding heat partially absorbed by the thermal radiation shield is efficiently transferred from the protruding part to the torque. Heat can be conducted to the tube and cooled, which has an excellent effect of increasing the mechanical strength and cooling effect of the thermal radiation shield.
