Magnetic suspension device having automatic centering function

Abstract

The invention discloses a magnetic suspension device having an automatic centering function. The magnetic suspension device comprises a solenoid coil, an iron core, an armature and a connection ring, wherein the solenoid coil is used for acquiring a suspension magnetic force, the iron coil is used for being changed to a magnet after being magnetized by a magnetic field of the energized solenoid coil and is mutually superposed with the magnetic field of the solenoid coil so that the magnetism of the solenoid coil is enhanced and the magnetism is accordingly eliminated after the solenoid coil is de-energized, the armature is used for hanging a gyro sensing component in a north seeker, the armature is arranged in the interior encircled by the iron core when suspended, the position center can be automatically centered, the connection ring is a sealing cover in the shape of a circular ring and provided with an opening in the center, an internal thread is arranged on an inner wall surface of the sealing cover, and the connection ring is used for connecting the gyro sensing component in the north seeker and the armature. By the magnetic suspension device, the suspension center of the gyro sensing component in the north seeker can be automatically centered, so that the gyro sensing component is high in working position repeatability and is stable, and the magnetic suspension device has the characteristics of compact structure, high reliability, high environmental adaptability, small harmful torque and the like, and is suitable for instrument equipment with relatively high requirements on environmental adaptability and reliability.

Description

technical field [0001] The invention belongs to the technical field of inertial north-seeking and directional measurement, and specifically relates to a magnetic levitation device with an automatic centering function, which is installed in high-precision gyro north-seekers, gyro theodolite and other equipment, and the earth angular rate is sensitive by the suspension gyro sensitive element. The component on the sensitive axis realizes north-seeking. Background technique [0002] With the development of technology, the north-seeking accuracy of the north-finding instrument is getting higher and higher, and because it is often used in the field environment, the requirements for environmental adaptability and reliability are also high. It can be used normally under the condition of ℃, which has high requirements for various structural parts and electronic devices inside the North Finder. [0003] At present, the gyro sensitive elements used in the gyro north finder include met...
