Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.

[0025] A method for preventing loosening of a gyro motor lock nut, comprising the following steps:

[0026] ⑴. Prepare equipment: including pneumatic dispensing machine, needle with outer diameter of Φ0.3mm and needle tube, etc.; prepare glue for bonding: epoxy resin thermosetting glue;

[0027] (2) Process the lock nut (that is, the lock nut) 8, and process two cross grooves 7 on the end surface of the motor lock nut. The two grooves are dispensing grooves, and the two grooves are vertically arranged. The size of each groove All are: groove width 0.2mm-0.6mm, depth 0.2mm-0.6mm. The depth of the groove is preferably 0.4mm, and it is reserved. The size of the groove is determined according to the convenience of ...

Abstract

The invention relates to a gyro motor locking nut anti-loosening method, mainly aims at solving the problems about gyroscope drifting long-term stability and gyro motor performance changes, and particularly relates to a high-precision liquid floating gyroscope gyro motor locking nut anti-loosening method which adopts a dynamic pressure air bearing and is highly sensitive to centroid precision. Themethod includes dispensing nut structure design and a dispensing nut technology achieving method. By adoption of the method, interference fit is not needed, the dispensing measure is implemented after motor testing is finished and is the important technology measure for supporting gyroscope batched production, and the gyro motor locking nut anti-loosening method is suitable for medium-high-precision liquid floating gyroscopes and particularly suitable for a liquid floating gyroscope system adopting a dynamic pressure bearing.

Description

technical field [0001] The invention relates to the technical field of liquid floating gyroscopes, in particular to a method for preventing loosening of locking nuts of gyroscope motors. Background technique [0002] The core of the liquid floating gyro is a gyro flywheel driven by a motor to rotate at a high speed. The motor part is installed on the gyro frame part. When the external angular velocity is input, the gyro frame part precesses along the output axis, and the measured precession value can reflect the input angular velocity. the size of. Therefore, it is first required that the frame members cannot have a moment along the output in the absence of the input. If the nut is loose after the assembly is completed, the center of mass of the frame assembly will be slightly displaced, thereby generating a harmful moment and causing a change in the gyro drift. High-precision gyroscopes must take measures to prevent loosening. [0003] At present, there are two methods c...
