Abstract

A miniature dynamically tuned gyroscope includes a base body assembly, a motor rotor assembly arranged on the base body assembly, and a mounting plane for the gyrorotor assembly; the base body assembly is provided with a shaft sleeve of a motor driving shaft, and the motor driving shaft penetrates through the shaft sleeve so as to connect the gyrorotor assembly with the motor rotor assembly; a rear cover assembly and a front cover assembly are sealed with the base body assembly by laser welding, a prepositioned amplification circuit board is welded with the front cover assembly through an insulator, and the prepositioned amplification circuit board is externally provided with a circuit board protection shield; the gyrorotor assembly is provided with a flexible joint, a thin neck of the flexible joint has a reed shape inclined 45 DEG relative to a rotating shaft, and the interior of the gyrorotor assembly is provided with a torque stator magnetic steel structure formed by two radial magnetization magnetic steel rings and two axial magnetization magnetic steel rings; the front cover assembly is provided with a plurality of blind holes, signal devices are mounted on a front cover, core shafts of the signal devices are fixed with the blind holes, and signal device coils adhere on the signal device core shafts.

Description

technical field [0001] The invention relates to an angular rate testing device, in particular to a miniature power tuning gyroscope. Background technique [0002] Miniature dynamic tuning gyroscope is the core component of the inertial system. It has the characteristics of small size, light weight, long life, low power consumption, and fast startup. It is widely used in the control systems of aircraft, tanks, missiles, and ships. In recent years, with the rapid development of weapons and equipment, many fields have put forward higher requirements for micro-dynamically tuned gyroscopes, not only requiring high-precision micro-dynamically tuned gyroscopes, small size, light weight, fast start-up, and low power, but also It is required that the gyroscope has strong environmental resistance and high reliability. The existing micro-dynamically tuned gyroscopes cannot meet the harsh environmental requirements and high reliability requirements. Therefore, it is necessary to develo...
