According to the precise assembling structure, the distance between an upper electrode plate and a rotor body can be adjusted by using gaskets of different thicknesses, so as to adjust the static capacitance of the upper electrode plate; and a microcomputer electric interface circuit board can also be put on the lower electrode bracket, so that the length of a lead is shortened, and the signal anti-jamming capability is improved.

Description

technical field [0001] The invention relates to a micro-dynamic tuning gyroscope, in particular to a precision assembly structure of a static capacitance-adjustable micro-tuning gyroscope. Background technique [0002] The dynamic tuning gyroscope was developed in the 1960s. It is a kind of two-way gyroscope that uses a flexible support to suspend the rotor. The inner ring of the gyroscope rotor is fixedly connected with the drive motor. degrees of freedom gyroscope. The power tuning gyro drive motor drives the gyro rotor to rotate at high speed through the drive shaft and the flexible joint. The structure of the flexible joint can ensure that when the gyroscope has a speed perpendicular to the drive shaft, the gyroscope rotor generates a relatively deflection signal relative to the housing. On the one hand, the deflection angle of the rotor is determined by detecting the deflection signal. On the other hand, the signal generates torque through electrostatic force feedback...
