Abstract

The present invention discloses a gyrorotor mass center position precision regulation device for solving abrasive dust pollution and an installation method thereof, belonging to the field of precisionmachinery mini-displacement regulation. A spiral device is added between a regulation screw and a gyroscope clamp, and in a regulation process, rotation motion of a rotation sleeve is converted to linear motion of a moving stud to drive the linear motion of the regulation screw so as to achieve a purpose of regulating the gyrorotor mass center position. The regulation screw is manually screwed into a rotor screwed hole so that the regulation screw and the rotor screwed hole are not relatively moved in the regulation process, the wearing problem cannot be generated, the wearing can be only generated at the external portion of the gyroscope tool, and the problem is creatively solved that the gyroscope is polluted by abrasive dust. The gyrorotor mass center position precision regulation device for solving abrasive dust pollution and the installation method thereof can thoroughly solve the abrasive dust pollution problem, can improve the qualified rate of the gyroscope, can reduce the unqualified products and can be widely applied to the mini-displacement precision regulation process.

Description

technical field [0001] The invention belongs to the field of micro-displacement adjustment of precision machinery, and in particular relates to a fine adjustment device and an installation method for a centroid position of a gyro rotor which solves wear debris pollution. Background technique [0002] Gyroscopes play a key role in the detection of aircraft flight attitude and inertial guidance. The good performance of gyroscopes is crucial to the judgment of aircraft attitude. In order to ensure the measurement accuracy of the gyroscope, it is necessary to control the misalignment between the center of mass of the rotor and the axis of rotation within a certain range. Otherwise, when the rotor rotates at a high speed, the vibration of the gyroscope will be severe, and the measurement data error of the gyroscope will be large and the service life will be greatly increased. shorten. [0003] Most of the current gyro rotor dynamic balancing methods use manual adjustment, and th...
