Title:
AIR-AND WATER-COOLED COMPOSITE COOLING TYPE EDDY CURRENT JOINT
Document Type and Number:
Japanese Patent JPS5833966
Kind Code:
A
Abstract:
PURPOSE:To improve the cooling effect of an eddy current joint by sprinkling cooling water on the outer diameter surface of a drum from a cooling water box on the top of a frame and cooling a yoke, poles and coils by cooling air sucked from inlet and outlet side suction ports. CONSTITUTION:Cooling water is supplied into a cooling water box 10 provided at a frame 9 of an eddy current joint to sprinkle the water to the outer periphery of a drum 8 from a sprinkling hole b, is collected and exhausted at an exhaust box 13 under the frame 9. On the other hand, bearings, a yoke 3 are cooled by cooling air from an inlet side suction port 6, the air is pressurized by an inside cooling fan 8e of the drum 8 to cool the poles 2, and is discharged into the frame 9. Then, the cooling air from the outlet side suction port 12 is pressurized from the air passage 11a of a cover 11 through the outside cooling fan 8f of the drum 8 to cool the outside of the drum 8, and is discharged. Accordingly, the cooling effect can be remarkably improved by a composite cooling type of the cooling water and the cooling air.
