Abstract

The invention aims to provide an ultra-miniature flexible gyroscope, which includes a box body and a gyro body installed inside the box body. A miniature connector with a cable is connected with the gyro body through a cable, the gyro body comprises a gyro rotor assembly, the gyro rotor assembly is coaxially arranged with a permanent magnet gyro motor, a seat body assembly is arranged between thegyro rotor assembly and the permanent magnet gyro motor, and the gyro rotor assembly comprises a flexible supporting assembly formed by fixing connection of a receiver rest type flexible support and acapturing tuning mechanism. The ultra-miniature flexible gyroscope is used for position signals or angular rate signals of two orthogonal directions of a sensitive carrier and outputting direct voltage signals proportional to the carrier attitude, can be used for inertial stabilization and follow-up systems such as micro-miniature seekers, gun-launched missiles, guided cartridges, airborne pods,radar tracking, artillery control, and taken as a measurement element for inertial control.

Description

technical field [0001] The invention relates to an ultra-miniature flexible gyroscope with an integral leaf spring type flexible support. The flexible gyroscope has a two-degree-of-freedom working mode and can be sensitive to the orthogonal X and Y axial working postures of the carrier. It is a kind of High reliability, high overload, medium precision miniature electromechanical inertial sensor. Background technique [0002] Existing flexible gyroscopes have dimensions greater than or equal to Φ21.4mm×30.5mm, and the anti-vibration capability is less than or equal to 0.2g 2 / Hz, the impact resistance is less than or equal to 450g, and the start-up time at full temperature is greater than or equal to 4s, which cannot meet the requirements of micro-miniature inertial stabilization systems and petroleum logging equipment. The traditional flexible gyroscope adopts combined aperture flexible support and integral aperture flexible support, boss type torque device, "U" shaped iron...
