Description

technical field [0001] The invention relates to mechanical sensing measurement technology, in particular to a measuring device for output torque and deflection angle of a steering gear. Background technique [0002] The steering gear is an important part of the missile control system, which is directly related to the strike accuracy of the missile. Its function is mainly to convert the control torque proportionally according to the polarity and size of the guidance error signal of the seeker, and the control torque pushes the deflection of the missile rudder surface, thereby realizing the control of the missile pitch and yaw motion. Therefore, the measurement of torque is a very important technical indicator. [0003] At present, the torque of the steering gear is mainly measured by the torque sensor, which has the following defects: First, there will be instrument errors in electronic products that need to be calibrated, and the calibration of the torque sensor is not easy...
