Abstract

The invention relates to a three-floating gyro, in particular to a miniaturized three-floating gyro, and solves the technical problem that the axial size of the existing three-floating gyro is large.The technical solution of the invention is that a miniaturized three-floating gyroscope comprises a float, an angle sensor, a torquer, a casing, a first axial magnetic levitation, a second axial magnetic levitation, a first radial magnetic levitation and a second radial magnetic levitation, wherein the float, the axial magnetic levitations, the radial magnetic levitations, the angle sensor and thetorquer are arranged in the casing; suspension is filled in the casing; a first end cover and a second end cover are respectively disposed at both ends of the casing; the first end cover is sleeved with a first axial magnetic levitation stator, a first radial magnetic levitation stator and an angle sensor stator in sequence from inside out; an axial magnetic levitation rotor is fixed at the center of one end surface of the float; a first radial magnetic levitation rotor and an angle sensor rotor are sequentially sleeved on the outer side thereof; and the first radial magnetic levitation rotoris located between the first radial magnetic levitation stator and the angle sensor stator.

Description

technical field [0001] The invention relates to a three-float gyroscope, in particular to a miniaturized three-float gyroscope. Background technique [0002] The three-floor gyroscope uses the principle of gyro precession and uses the angular displacement of the sensitive inertial measurement system to deviate from the inertial coordinate system to provide an attitude angle signal for the control system, thereby realizing inertial navigation. It is the core device in the field of high-precision navigation. The three-float gyroscope is the development and improvement of the single-degree-of-freedom liquid floating integral gyroscope. It uses a dynamic pressure air bearing motor instead of a ball bearing motor to improve the life and accuracy of the gyroscope; it uses magnetic levitation technology to eliminate mechanical friction torque and accurately determine the float assembly. , to further improve the gyroscope accuracy. Because liquid floating technology, dynamic pressu...
