Abstract

A torque transfer device is used for international comparison between torque standard machines or for comparison verification between a torque standard machine and torque calibration machine. This experimental study revealed a problem in the case of using a high-precision torque transducer as the transfer device. For a disk-type torque transducer, it was found that a considerable deviation in the torque output sensitivity occurred depending on the dimensions of the adapter flange and the fastening torque of the screw bolts directly connecting the torque transducer to the adapter flanges. A solution is proposed to overcome this difficulty.
