Abstract

The invention discloses a built-in precise centering device of a gyroscope. The built-in precise centering device comprises a shell, a through hole, a suspension body, a buffer pad, a jewel bearing, an electromagnet, a magnet and a magnetic shielding cover; The through hole is formed in the center of the shell, the suspension body is installed in the through hole, and the buffer pad is arranged between the through hole and the suspension body. The jewel bearing is mounted in the suspension body; the magnet is arranged in the suspension body and is mounted on the lower surface of a bulge on the outer side of the top end of the suspension body; the electromagnet is arranged in the shell, the electromagnet is arranged in the shell below the external expansion groove at the top end of the through hole, the electromagnet is opposite to the magnet on the suspension body, and the magnet is matched with the electromagnet. The built-in precise centering device has the characteristics that rigid contact and abrasion are avoided, the centering control circuit detects and adjusts magnetic suspension centering, and magnetic field interference on the gyroscope is reduced.

Description

Technical field [0001] The present invention relates to a gyroscope's built-in precision pair device, in particular, has a built-in precision of a gyroscope that avoids rigid contact and wear, a pair control circuit to magnetic suspension pair, reducing the gyroscope Middleware. Background technique [0002] The three floats are a new gyroscope integrating liquid float, dynamic air floating, magnetic suspension, which is mainly composed of float assemblies, torque holder assemblies, sensor seat assemblies, left and right end caps, magnetic suspension bearings, and the like. Among them, the magnetic suspension element geometry center, force center, and signal center non-coefficient is an important factor that causes the accuracy error of the meter, and is also the main reason for the magnetic suspension interference moment, so the magnetic suspension bearing requires high pairs of assembly accuracy. [0003] At present, the magnetic suspension bearing assembly process is simply de...
