Claims
- 1. In a rotor of a superconductive generator having a torque tube in a damper, a shaft and a superconductive coil fitted to said torque tube, an improvement comprising:
- said damper and said torque tube being formed in one piece without a movable part by directly and firmly connecting said damper and said torque tube to each other at each end of said torque tube by one of welding and bolting said damper to said torque tube;
- said damper having a thickness at least two times the thickness of said torque tube such that the ratio of thermal stress to resistance in said torque tube is at least as great as that in said damper;
- said torque tube having a heat insulating part; and
- said torque tube having a coil fitting part wherein a thickness of said coil fitting part of said torque tube is thicker than a thickness of said heat insulating part.
- 2. A rotor of a superconductive generator according to claim 1 further comprising:
- a flange rotatable with said shaft in one unit with said flange being connected by a connection means to said one piece formed by said damper and said torque tube.
- 3. A rotor of superconductive generator according to claim 1, wherein said one of welding and bolting comprises welding.
- 4. A rotor of superconductive generator according to claim 2, wherein said connection means comprises welding.
- 5. A rotor of a superconductive generator according to claim 1, wherein said one of said welding and bolting comprises bolting.
- 6. A rotor of a superconductive generator according to claim 2, wherein said connection means comprises a bolt.
- 7. A rotor of a superconductive generator according to claim 1, wherein said damper and said torque tube are made of titanium and titanium alloy.
- 8. A rotor of a superconductive generator according to claim 2, wherein said damper and said torque tube are made of one of titanium and titanium alloy.
- 9. A rotor of a superconductive generator according to claim 3, wherein said damper and said torque tube are made of one of titanium and titanium alloy.
- 10. A rotor of a superconductive generator according to claim 4, wherein said damper and said torque tube are made of one of titanium and titanium alloy.
- 11. A rotor of a superconductive generator according to claim 5, wherein said damper and said torque tube are made of one of titanium and titanium alloy.
- 12. A rotor of a superconductive generator according to claim 6, wherein said damper and said torque tube are made of one of titanium and titanium alloy.
- 13. A rotor of a superconductive generator according to claim 2, further comprising:
- said torque tube having a heat insulating part; and
- said torque tube having a coil fitting part wherein a thickness of said coil fitting part of said torque tube is thicker than a thickness of said heat insulating part.
- 14. A rotor of a superconductive generator according to claim 1, wherein said superconductive coil is placed outside of said torque tube.
- 15. A rotor of a superconductive generator according to claim 1 wherein said damper and said torque tube are made of a titanium alloy.
