本発明は超電導回転子に係り、特にエンド段付部のある
超電導界磁巻線（以下、界磁巻線と称する）を有する超
電導回転子に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a superconducting rotor, and more particularly to a superconducting rotor having a superconducting field winding (hereinafter referred to as field winding) with stepped end portions.
周知のように超電導回転子は一般に超電導発電機あるい
は超電導電動機の回転界磁として用いられるものであり
、その超電導回転子の従来例が第１図に示されている。As is well known, a superconducting rotor is generally used as a rotating field for a superconducting generator or a superconducting motor, and a conventional example of such a superconducting rotor is shown in FIG.
超電導回転子は主に円筒状のトルクチューブ１、界磁巻
線２、ダンパー３Ａ。The superconducting rotor mainly includes a cylindrical torque tube 1, a field winding 2, and a damper 3A.

循環し界磁巻線２を４〜５にの極低温に冷却している。A field winding 2 is supported on the outside of the torque tube 1, and the inside of the torque tube 1 is filled with liquid helium 5. The field winding 2 is housed inside the cylindrical vessel 6, but the inside of the torque tube 1 and the inside 13111 of this vessel 6 communicate with each other, so that the liquid helium 5 circulates and the field winding 2 is cooled to an extremely low temperature of 4 to 5 degrees centigrade.

Ａ、７Ｂを介して回転軸４Ａ。Dampers 3A and 3B are provided on the outside of the field winding 2 to prevent the fluctuating magnetic field from the stator core winding from entering the field winding 2, and to prevent the fluctuating magnetic field from entering the field winding 2 from the radial direction. Prevents heat intrusion. Both ends of the torque tube 1 are connecting pipes 7
Rotary shaft 4A via A and 7B.

線２はエンド部の最大磁束密度を低減するために、最近
ではエンド部形状を第２図に示しであるように階段状の
段付きにすることが試みられている。4B, and the rotating shafts 4A, 4B are connected to bearings 8A, 8, respectively.
Supported by B. The rotating shaft 4A is connected to a turbine (not shown), and the rotating shaft 4B is connected to a helium liquefaction machine (both not shown) via a helium supply/discharge device. In order to reduce the maximum magnetic flux density at the end of the field winding 2, recent attempts have been made to make the end of the field winding 2 step-shaped as shown in FIG.
このようなエンド段付部を有する界磁巻線２を支持する

の外周上には円筒状ベッセル６が焼嵌めされている。The torque tube 1 supporting the field winding 2 having such an end stepped portion is provided with a protrusion 9 supporting the trap end stepped portion as shown in FIG. 3 in order to improve support. A step-like stepped portion similar to the end stepped portion on which the end stepped portion is placed is provided on the projection portion 9. and field winding 2
is installed on the outer periphery of the torque tube 1 via a spacer 11 for forming a cooling channel 10, but even if the protrusion 9 of the torque tube 1 is stepped like this, the protrusion 9 Since a gap 12 of nttm is formed between the stepped part and the end stepped part of the field winding 2, this gap 12 is filled with an adhesive 13 to provide a good support for the field winding 2. There is. As shown in FIGS. 4 and 5, a bind support layer 14 with a circular inner core is provided on the outer periphery of the field winding 2 supported in this manner, and a cylindrical bind support layer 14 is provided on the outer periphery of the bind support layer 14. A shaped vessel 6 is shrink-fitted.

業なので作業が容易でなく、とりわけ界磁巻線２のエン
ド段付部を乗置させる段付部の作成は、界磁巻線２のエ
ンド段付部の寸法精度が悪い場合等は容易でなかった。Incidentally, the protrusion 9 of the torque tube 1 that supports the field winding 2 is formed by cutting out a cylindrical object or by welding the protrusion to the cylindrical object, but in both cases, the process is done as one piece with the rotating shaft. The work is not easy, especially when creating the stepped portion on which the stepped end portion of the field winding 2 is placed is not easy when the dimensional accuracy of the stepped end portion of the field winding 2 is poor. .

チ）を起す恐れがあった。However, the workability of filling the adhesive 13 between the stepped portions of the torque tube 1 and the field winding 2 is poor, and the adhesive 13 flows into the cooling channel 10 and fills the cooling channel 10. This impairs the cooling of the field winding 2. To avoid this, if the adhesive 13 whose curing reaction has progressed and the viscosity has increased is filled, it will not flow into the cooling channel 10, but there will be areas where the adhesive 13 is not filled sufficiently, and the adhesive 13 will crack during rotation, causing the field The winding 2 could not be supported sufficiently, and there was a risk that the field winding 2 would be destroyed by normal conduction (quench) due to frictional heat and changes in interlinkage magnetic flux accompanying the movement of the field winding #J2.
本発明は以上の点に鑑みなされたものであシ、その目的
とするところは超電導界磁巻線のクエンチを防止した超

きる。Note that parts that are the same as those in the conventional model are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, at the end corner of the field winding 2,
In addition, a stepped spacer 15 for placing an end stepped portion is attached between the field winding 2 and the torque tube 1, and the stepped spacer 15 and the field winding 2 are integrated with an adhesive 13. It was molded into. By doing this, the field winding 2 is firmly supported by the stepped spacer 15, and a superconducting rotor in which the field winding 2 is prevented from being quenched can be obtained.

けでよく、その農作を容易にすることができる。In other words, the stepped portion 1 on which the end stepped portion of the field winding 2 is placed
The field winding 2 with the stepped spacer 15 (see Fig. 6) attached thereto is placed on a cylinder having the same outer diameter as the outer diameter of the spacer attached to the outer periphery of the torque tube 1, and is subjected to a mold release process. After the field winding 2 is held down, the field winding 2 is
and stepped spacer 15 are integrally molded with adhesive 13. Then, the integrally molded field winding 2 is removed from the cylinder, bolted to the torque tube 1 through the bolt mounting hole 17, and a torque is applied on the outer periphery of the bolted field winding 2 in the same manner as described above. An inner circular bind support layer is formed with the tube 1, and a cylindrical vessel is further shrink-fitted onto the outer periphery of the bind support layer. In this way, even if the dimension of the end stepped part of the field winding 2 is made somewhat inaccurately, the stepped spacer 15
Since the processing is done as a single item, it is easy to fit the end stepped part together, and since the filling of the adhesive 13 is carried out on the field winding 2 alone with the stepped spacer 15 attached, it is possible to fill the cooling channel as in the conventional method. There is no concern and it can be filled well enough. In this way, the stepped end portion of the field winding 2 can be firmly supported by the torque tube l via the stepped spacer 15, so quenching of the field winding 2 can be prevented. In addition, the protrusion 9 of the torque tube 1 only needs to be able to reach a linear protrusion, making farming easier.

It is possible to obtain a superconducting rotor in which the support of the superconducting rotor is strengthened and quenching of the superconducting field windings is prevented.
