A torque standard device suitable for extreme environment is designed. The standard device transmits the torque value of calibrated torque sensor in extreme environment to normal temperature environment through torque transmission shaft to realize the calibration function. The mechanical design of the shaft of the device is carried out, and the error sources of the calibration device are analyzed, and the error distribution is carried out according to the technical indicators of the standard device. The calculation results show that the maximum allowable error of the standard device is 0.7Nm, which meets the calibration accuracy requirements of the extreme torque standard device.
