A closed-circuit magnetization structure of a liquid-floating gyroscope stator magnet

Abstract

The invention relates to a closed-circuit magnetization structure of a liquid-floating gyroscope stator magnetic steel, comprising a stator seat and a magnetic steel, and is characterized in that it further comprises a push screw, a magnetic conducting magnetic circuit, an expansion mother, an expansion ring, a stopper piece and a screw, The magnetic conductive magnetic circuit is in the shape of a sleeve with an open bottom. The lower part of the push screw extends into the inner cavity of the magnetic conductive magnetic circuit, and is threadedly connected with the top surface of the magnetic conductive magnetic circuit. The female outer is covered with an expansion ring, and the lower part of the expansion ring is provided with a stopper piece, and the stopper piece is fixed by the screw and the bottom end of the push screw. And the magnetic steel is pulled into or out of the inner cavity of the magnetically conductive magnetic circuit. The invention is used for the closed-circuit magnetization structure of the stator magnetic steel of the liquid floating gyroscope. The magnetization of the stator seat, the magnet steel and the installation of the shell are all located in the magnetization magnetic circuit, thereby greatly reducing the magnetic field caused by the change of the magnetic circuit of the stator. decrease in strength.

Description

technical field [0001] The invention belongs to the technical field of inertial measurement sensors, in particular to a closed-circuit magnetization structure of a liquid-floating gyroscope stator magnetic steel with high precision, small volume and low cost. Background technique [0002] At present, there are no reports on the maintenance of Soviet-made gyroscopes in China. This type of gyroscope involves a very strict index during the maintenance process, that is, the range of the gyroscope scale factor. Therefore, it is necessary to ensure that the magnetic field strength of the torquer stator magnet cannot be lost too much during the maintenance process. However, the material of the stator magnetic steel of this type of liquid-floating gyro torquer is AlNiCo alloy. During the maintenance process, the stator will be taken out from the gyroscope housing, resulting in the change of the magnetic circuit and the reduction of the magnetic field strength of the stator magnetic...

Problems solved by technology

However, the material of the stator magnetic steel of this type of liquid floating gyro torquer is AlNiCo alloy. During the maintenance process, the stator will be taken out of the gyroscope shell, resulting in changes in the magnetic circuit, resulting in a decrease in the magnetic field strength of the stator magnetic steel, making maintenance difficult. conduct

[0003] The current solution to this problem is to replace the brand new torquer stator magnet, but it still cannot avoid the problem that the stator magnet is taken out of the magnetizer and the magnetic field strength is reduced
