Rotary torque calibration device based on static torque standard machine

The utility model relates to a rotating torque calibration device based on a static torque standard machine, which is characterized in that a rotating shaft of a calibrated phase difference type torque sensor is connected in series in the rotating torque calibration device through a flange, and one end of the rotating torque calibration device carries out torque loading through a standard force arm system; a standard torque value is given to the calibrated phase difference type torque sensor, a shell of the phase difference type torque sensor is installed on a connecting flange shaft through bearings at the two ends, and the shell is connected with a motor on a workbench of the rotating torque calibration device through a belt wheel and a belt, so that the shell is dragged by the motor and the belt wheel to rotate. Therefore, the rotating shaft and the housing of the phase difference type torque sensor generate relative rotation, and torque measurement and calibration are carried out. According to the utility
