JOINT STRUCTURE OF SUPERCONDUCTING MOTOR

Japanese Patent JP2016019396

A

PROBLEM TO BE SOLVED: To provide a joint structure of a superconducting motor which is easily assembled and in which leakage of a coolant can be prevented.SOLUTION: The joint structure of the superconducting motor for coupling a side of cooling device which supplies the coolant for cooling a rotor 2, and a rotor side includes: a columnar fixed-side member 10 which is connected to the side of the cooling device and includes a small diameter part 11 at the side of the rotor 2; a cylindrical rotatable-side member 20 which is fixed to the side of the rotor 2 and through which the fixed-side member 10 is inserted; and a cylindrical sliding bearing 30 which is inserted through the rotatable-side member 20 in a relatively freely rotatable manner and through which the small diameter part of the fixed-side member 10 is inserted. The rotatable-side member 20 includes a double cylindrical part at a position opposite to the side of the rotor 2 in the small diameter part 11 of the fixed-side member 10, and the sliding bearing 30 includes a groove part 31 fitted into an inner cylinder of the double cylindrical part in the rotatable-side member 20 at a position opposite to the double cylindrical part of the rotatable-side member 20.SELECTED DRAWING: Figure 1
