TESTING MACHINE OF MECHANICAL MOTIVE POWER CIRCULATION SYSTEM AND METHOD FOR TESTING ENDURANCE PERFORMANCE OF SHAFT-SHAPED BODY

摘要

PROBLEM TO BE SOLVED: To provide a testing machine of a mechanical motive power circulation system and a method for testing the endurance performance of shaft-shaped bodies capable of continuous differential motion through the use of electric motors of smaller capacity than before and highly efficiently and highly accurately testing the endurance performance of the shaft-shaped bodies for transmitting the rotary motion of a viscous coupling, torque converter, etc. SOLUTION: In the method for testing the endurance performance of the shaft-shaped bodies for transmitting rotary motion, the two shaft-shaped bodies 201 and 202 are mounted to a test apparatus 1 (a). Two drive electric motors MA and MB and two differential electric motors ma and mb are controlled in such a way that all two drive outputs OA and OB and two differential outputs oa and ob take the same number of revolutions (b). Then, the two differential electric motors ma and mb are actuated and controlled in such a way that the drive outputs and the differential outputs each connected to the shaft-shaped bodies 201 and 202 take a specific relation (c).
