TORSION TEST DEVICE

摘要

A torsion test device configured to apply torques to input/output shafts of a test body, including a first driving unit connecting with an input shaft of the test body, and a second driving unit connecting with an output shaft of the test body, each driving unit including a servo motor, a reduction gear reducing a rotational speed of an output shaft of the servo motor, a chuck configured to clamp one of the input shaft and the output shaft of the test body, and transmit an output force from the reduction gear to the one of the input shaft and the output shaft of the test body, a torque sensor configured to transmit the output force from the reduction gear to the chuck, and detect a torque output from the reduction gear, and a rotation detector configured to detect a rotational frequency of the chuck.
