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...

Problems solved by technology

[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 to operate, which requires high technical requirements for the operator. Improper calibration of the torque sensor will lead to inaccurate measurement; second, the use of the torque sensor will have many precautions and operational requirements, and operational errors will lead to inaccurate measurement; third, the deflection angle of the steering gear is also an important technology indicators, and the existing electronic products for measuring the torque of the steering gear can only measure the torque, but not the angle of deflection of the steering gear; Fourth, the electronic products used for measuring the torque of the steering gear are expensive and prone to failure
