Problems solved by technology

[0007]In order to solve the existing method of using a complete set of formal gyroscope components to realize the static balance of the float, it needs to be assembled by gluing, gluing, and welding, which is time-consuming and laborious. The high stress of decomposing and disassembling the buckle glue will easily affect the accuracy of the important components of the gyroscope, and it will also scrap some glued and welded components. The invention provides a liquid floating gyroscope test assembly device based on a full rubber ring sealing structure

Embodiment 1

[0037] The liquid floating gyroscope trial installation device based on the full rubber ring sealing structure provided by this embodiment is as follows: figure 1As shown, it includes a single-end open shell 1, a bellows assembly 2 arranged at the left end of the shell 1, and a bellows press for pressing the bellows assembly 2 on the shell 1 and screwing it with the shell 1. The ring 3 , the end cover assembly 4 arranged at the right end of the housing 1 , and the end cover pressing ring 5 for pressing the end cover assembly 4 on the housing 1 and screwing it with the housing 1 .

[0038] Considering the large sealing surface between the bellows assembly 2, the end cover assembly 4, and the housing 1, and the micron-level axial and radial clearance assembly requirements of the float assembly, it is easy to process, stable in structure, high in sealing reliability and easy to control. The sealing structure of the O-shaped sealing rubber ring that seals the depth of compression ...

Abstract

The invention relates to a liquid floated gyroscope trial assembly device based on a full-rubber-ring sealing structure, and aims to solve the problems that according to an existing method for achieving static balance of a floater through a whole set of formal gyroscope components, assembly needs to be conducted in a gluing and welding sealing manner, the time and labor are wasted, and part of the components can be scrapped when buckle rubber is disassembled and disassembled. The device comprises a shell, a corrugated pipe assembly arranged at one end of the shell, a corrugated pipe pressing ring which is used for pressing the corrugated pipe assembly on the shell and is in threaded connection with the shell, an end cover assembly arranged at the other end of the shell, and an end cover pressing ring which is used for pressing the end cover assembly on the shell and is in threaded connection with the shell. A first O-shaped sealing rubber ring is arranged between the end face at one end of the shell and the corrugated pipe assembly, and a second O-shaped sealing rubber ring is arranged between the end face at the other end of the shell and the end cover assembly. A corrugated pipe oil filling nozzle is arranged at the outer side of the corrugated pipe assembly, an end cover oil filling nozzle is arranged at the outer side of the end cover assembly, and sealing gaskets and plugging screws are arranged at the inlets of the corrugated pipe oil filling nozzle and the end cover oil filling nozzle.

Description

technical field [0001] The invention relates to a liquid floating gyroscope static balance device, in particular to a liquid floating gyroscope test assembly device based on a full rubber ring sealing structure. Background technique [0002] Liquid-floating gyroscopes (including liquid-floating, two-floating, and three-floating gyroscopes) are widely used in inertial navigation systems, and are used to measure the angular rate of aircraft. Its main feature is that the rotor is sealed in a float filled with inert gas, and the float is suspended in a suspension (fluorine oil). The suspension needs to be heated and stabilized to the suspension temperature. Through precise static balance and temperature control, the float The buoyancy and gravity are completely balanced to realize the unloading of its supporting bearings, thereby fully reducing the friction moment between the float and the positioning shaft, and has the advantages of high precision, high reliability, and strong ...
