Problems solved by technology

[0031] 1. Remagnetize the torquer stator to saturation, but the gyro calibration still cannot be achieved. This is due to the change in performance of the material after long-term use;
[0032] 2. Replace the material and reprocess the new stator. This method has high economic and time costs, and there are technical risks

Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the drawings and specific examples. The following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0054] A dismantling method applied to the maintenance of liquid floating gyro, please refer to Figure 4-7 , its invention point is: use extension sleeve 1 and outward movement guide 2, the material of described extension sleeve is the same as the material of gyroscope shell, the inner hole of described extension sleeve is guided by the main body section 1.1 and is located in the extension sleeve. The positioning hole section 1.2 at one end is formed; the aperture and tolerance of the main guide hole section are consistent with the inner hole diameter and tolerance of the gyro casing; the aperture diameter of the positioning hole section is consistent with the outer diameter of the gyro casing. One end of the outward movement...

Abstract

The invention relates to a dismantling method applied to the maintenance of a liquid floating gyroscope, which uses an extension sleeve and an outwardly moving guide. Mechanically disassemble the welding seam; 2. Coaxially and fixedly connect the stator seat connection end of the outward movement guide with the outer end of the torquer stator seat; 3. Insert the end of the gyro shell into the positioning hole section of the extension sleeve. 4. Hold the hand-held operating end of the outward movement guide and pull the outward movement guide outward. The outward movement guide drives the torquer stator seat and the torquer stator to move out of the gyro housing and move into the extension sleeve to realize the disassembly of the torque stator. The method of the invention has the advantages of easy implementation, simple operation and low implementation cost, and ensures that the scale of the gyroscope will not go out of tolerance, thereby ensuring the success rate of gyroscope maintenance.

Description

technical field [0001] The invention belongs to the technical field of repair and maintenance of liquid floating gyroscopes, and in particular relates to a dismantling method applied to the maintenance of liquid floating gyroscopes. Background technique [0002] When applied to some occasions with limited space, the space provided for the liquid floating gyroscope is relatively small. The composition of a miniaturized liquid floating gyroscope mainly includes: a gyroscope housing 101, a torquer stator seat 102, a torquer stator 103, and a torquer moving ring 104, see figure 1 , 1a, is a longitudinal sectional view; 1b, is a schematic cross-sectional view; the structural features mainly include: [0003] 1. In order to meet the needs of miniaturization design, the shell of the gyro will use iron-nickel soft magnetic alloy such as 1J85 and other materials, which not only serve as the overall support and mounting surface of the gyro, but also serve as the outer magnetic ring o...
