Abstract

The invention belongs to the technical field of two-floating gyroscope installation and adjustment, and particularly relates to an installation method of a dynamic pressure motor and a frame assembly. The problems that due to the fact that the combination portion of a motor shaft of an H-type double-stator dynamic pressure motor and a frame assembly is different in deformation after thermal expansion and cold contraction, and due to the improper gluing portion, installation sequence and glue using amount, the mass center of a floater assembly is unstable, and finally the stability of a gyroscope becomes poor are solved. According to the invention, a proper gluing part is selected, a specific gluing method is adopted, a proper assembly sequence is matched, and meanwhile, the glue consumption of the corresponding gluing part is controlled, so that the mass center stability of the floater assembly after assembly can be ensured, and the stability of the gyroscope is further improved. The method is an important process measure for supporting the mass production of gyroscopes, solving the long-term stability of the drift coefficient of the gyroscopes and the performance change of the H-type double-stator dynamic pressure motor, and is suitable for medium-high-precision liquid floated gyroscopes, especially liquid floated gyroscope systems adopting dynamic pressure bearings.

Description

technical field

[0001] The invention belongs to the technical field of gyroscope assembly and adjustment, and in particular relates to an installation method of a dynamic pressure motor and a frame assembly. Background technique

[0002] Due to its anti-vibration, impact resistance, high reliability, and long life, the two-floating gyroscope is widely used in navigation and attitude systems of spacecraft, satellites, space stations, missiles, and ships. It is a very important inertial sensor to measure the angular motion of the vehicle.

[0003] The manufacturing process of the second floating gyro involves difficult precision machining and precision assembly technology. The residual stress generated by assembly stress and bonding stress will affect the stability of the gyro, which in turn will affect the accuracy of navigation and attitude systems.

[0004] The float assembly is the key component of the second float gyroscope, which is composed of the frame assembly 01 and...
