Abstract
The invention provides a symmetrical frame structure of a liquid-floated gyroscope. The symmetrical frame structure of the liquid-floated gyroscope comprises two symmetrical supporting cross beams, symmetrical frame discs at the two ends, a shaft hole, wire threading holes and wire distributing slots. The symmetrical frame structure of the liquid-floated gyroscope cleverly adopts an axisymmetric structure to replace an original briquetted fixed motor structure, and the motor can be fixedly connected with a frame through a locking mechanism. Through the axisymmetric structure, stress deformation caused by the frame can be reduced and the mass center offset of the gyroscope caused by thermal stress can be reduced, so that the purpose of improving the accuracy of the gyroscope is achieved.
Description
[technical field]
The present invention relates to inertial navigation instrument field, more particularly to a kind of liquid floated gyroscope symmetrical expression frame structure.
[background technology]
Liquid floated gyroscope is the critical component in inertial navigation system, and the precision of gyroscope directly affects whole system
Precision.For improving the lasting accuracy of system, gyroscope should have higher rigidity, and to meet the bandwidth requirement of system, therefore liquid floats
The rigidity of gyroscope becomes important Con trolling index during designing gyroscope.
Traditional liquid floated gyroscope frame structure is most of to adopt pressing block type structure, in gyro work, increasing over time
Plus, temperature raises, and produces thermal stress deformation, so that gyro centroid motion motor bearings is constantly worn and torn, motor performance is gradually lowered, from
And having influence on gyro performance, gyro overall life is limited by electrical machinery life.
[content of the invention]
It is an object of the invention to provide a kind of liquid floated gyroscope symmetrical expression frame structure.
Technical scheme is as follows: it is horizontal that described liquid floated gyroscope symmetrical expression frame structure includes two symmetrical supports
The symmetrical framework disk in beam, two ends, axis hole, cable-through hole and wiring groove.
Pressing block type structure is changed to axially symmetric structure by the liquid floated gyroscope symmetrical expression frame structure of the present invention, and symmetrical structure has
Beneficial to avoiding barycenter to produce displacement, thus improving the precision of liquid floated gyroscope on the whole.This frame structure improves original structure
The barycenter skew problem causing because of unsymmetric structure, has certain reference to the optimization design of the structure of liquid floated gyroscope.
Described liquid floated gyroscope symmetrical expression frame structure be ingenious using axially symmetric structure replace original pressing block type fix
Electric machine structure, motor can be connected firmly with framework by retaining mechanism.By axially symmetric structure, the stress of framework generation can be reduced
Deformation is it is also possible to reduce the gyro centroid motion that thermal stress causes, thus reaching the purpose improving Gyro Precision.
[brief description]
Fig. 1 is the schematic diagram of liquid floated gyroscope symmetrical expression frame structure.
Fig. 2 is the schematic diagram of another angle of liquid floated gyroscope symmetrical expression frame structure.
[specific embodiment]
Below by embodiment, the invention will be further described.
Refer to Fig. 1 and Fig. 2, including the symmetrical framework disk 2 in two symmetrical support beams 1, two ends, axis hole 3, cross line
Hole 4 and wiring groove 5.
Pressing block type structure is changed to axially symmetric structure by the liquid floated gyroscope symmetrical expression frame structure of the present invention, and symmetrical structure has

The barycenter skew problem causing because of unsymmetric structure, has certain reference to the optimization design of the structure of liquid floated gyroscope.
Described liquid floated gyroscope symmetrical expression frame structure be ingenious using axially symmetric structure replace original pressing block type fix
Electric machine structure, motor can be connected firmly with framework by retaining mechanism.By axially symmetric structure, the stress of framework generation can be reduced
Deformation is it is also possible to reduce the gyro centroid motion that thermal stress causes, thus reaching the purpose improving Gyro Precision.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to the protection model of the present invention
Enclose.
