Description

technical field [0001] The invention relates to the technical field of precision machining of aerospace inertial devices, in particular to a locking torque control device and method for a dynamic pressure motor. Background technique [0002] The micro dynamic pressure motor adopts the structure of the outer rotor, and the stator part is locked by the shaft system with lock nuts to lock the left and right hemispheres to ensure the stability of the center of mass of the motor shaft system. Therefore, the size of the nut tightening torque plays an important role in the stability of the motor center of mass. In the previous production process, the operator used the purchased torque wrench to control the locking torque, but in the process of using the purchased torque wrench, such as figure 1 As shown, the following issues exist in the discovery: [0003] 1. The precise control of the locking torque of each motor cannot be realized, and it can only be controlled within a certai...

AI Technical Summary

Problems solved by technology

[0003] 1. The precise control of the locking torque of each motor cannot be realized, and it can only be controlled within a certain range through hand calibration;

[0004] 2. The external dimension of the torque wrench is too large, which is easy to generate interference torque;

[0005] 3. The locking torque cannot be fine-tuned during the production process;

[0006] 4. The other end of the motor is not fixed, and mutual interference will occur during the process of applying torque

The above problems will affect the quantitative control of the locking torque or cause damage to the appearance and performance of the motor
