Title:
SUPERCONDUCTIVE ROTOR
Document Type and Number:
Japanese Patent JPS57173367
Kind Code:
A
Abstract:
PURPOSE:To reduce the quantity of heat axially transmitted to a connecting tube by forming a connecting member which connects a rotational shaft to a torque tube by providing a reinforced plastic layer and a binding wire winding layer on the outer periphery of the connecting tube, thereby reducing the sectional area of the connecting tube. CONSTITUTION:A connecting member 12 which connects a rotational shaft to a torque tube is formd by providing a reinforced plastic layer 14 and a binding wire winding layer 15 on the outer periphery of a connecting tube 7. In this manner, the thickness of the cylindrical part of the tube 7 can be reduced, thereby reducing the quantity of heat transmitted axially.
