Title:
EDDY CURRENT REDUCTION GEAR
Document Type and Number:
Japanese Patent JP3956210
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide am eddy current reduction gear capable of easily detecting an operation failure.
SOLUTION: The temperature of a rotor is measured directly by a thermometer, or is measured indirectly by the thermometer provided at a non-rotation portion near the rotor to obtain temperature measurements. The measurements are compared with preset temperatures, and by the comparative results, a failure in the eddy current reduction gear is diagnosed.
