Description

Technical Field

[0001] This utility model relates to the field of high-precision gyroscope technology, specifically a composite gyroscope rotor for a high-precision gyroscope. Background Technology

[0002] A gyroscope, also known as an angular velocity sensor, is a device that uses the angular momentum of a high-speed rotating body to sense the angular motion of a housing relative to inertial space around one or two axes orthogonal to its rotation axis. At the same time, devices that use other principles to detect angular motion and perform the same function are also called gyroscopes. A compound gyroscope rotor is installed inside a gyroscope.

[0003] Patent document CN215865242U discloses a gyroscope rotor for a high-precision gyroscope, "including a gyroscope rotor, a flexible joint, an inner joint, and an outer joint. Symmetrical through-slots are provided between the inner and outer joints. An adjusting component fixed to the flexible joint is provided in the middle of the inner joint. Two permanent magnets are located inside the upper and lower ends of the gyroscope rotor, with an isolation magnetic ring between them. The gyroscope rotor is made of an alloy material with high-temperature resistance and oxidation resistance. The gyroscope rotor achieves its operating precision through the cooperation of the two sets of permanent magnets. The through-slots facilitate the dissipation of internal temperature and reduce the weight of the gyroscope rotor, resulting in higher rotational accuracy. Furthermore, the alloy material with high-temperature resistance and oxidation resistance prevents accelerated wear on the gyroscope rotor surface due to high internal temperature, thus improving the gyroscope rotor's service life and rotational accuracy." However, the stability of this gyroscope rotor installation is not high, causing the gyroscope to easily loosen after prolonged use.

[0004] In view of this, it is necessary to develop a high-precision composite gyroscope rotor for gyroscopes, thereby improving the stability of the gyroscope rotor in use. Utility Model Content

[0007] Preferably, the first connecting assembly includes a connecting rod, a fixed disc, and a toothed shaft. The fixed disc is installed at one end of the connecting rod, and the toothed shaft is installed on one side of the fixed disc.

[0021] Please see Figures 1-4 A composite gyroscope rotor for high-precision gyroscopes;

[0022] It includes: a gyroscope rotor body 1, and snap-fit ​​fixing components installed on both sides of the gyroscope rotor body 1. The snap-fit ​​fixing components include connectors 2, engaging grooves 3, a first connecting component 4, and a second connecting component 5. The connectors 2 are symmetrically installed on both sides of the gyroscope rotor body 1. The engaging grooves 3 are opened inside the connectors 2 and penetrate through the outside of the connectors 2. The first connecting component 4 and the second connecting component 5 are symmetrically installed on both sides of the gyroscope rotor body 1 through the connectors 2. The first connecting component 4 and the second connecting component 5 have the same structure.

[0023] The gyroscope rotor body 1 is installed inside the gyroscope. The supporting part of the gyroscope rotor body 1 and the housing is usually spherical, and the rotor can rotate freely relative to the housing. The gyroscope rotor body 1 provides a position for the installation of the snap-fit ​​fixing assembly. The gyroscope rotor body 1 is connected to the first connecting assembly 4 and the second connecting assembly 5. One end of the connecting rod 6 in the first connecting assembly 4 and the second connecting assembly 5 is inserted into the snap-fit ​​groove 3 opened inside the connector 2 through the snap-fit ​​shaft 8. After the snap-fit ​​shaft 8 is installed, the fixing disc 7 is fixed to the outside of the connector 2 by bolts. The gyroscope rotor body 1 is connected to the first connecting assembly 4 and the second connecting assembly 5 through the double fixing method, which makes the use stability of the gyroscope rotor body 1 higher.

[0024] The first connecting assembly 4 includes a connecting rod 6, a fixed disk 7, and a toothed shaft 8. The fixed disk 7 is installed at one end of the connecting rod 6, and the toothed shaft 8 is installed on one side of the fixed disk 7. The toothed shafts 8 are staggered inside the engagement groove 3, and the connecting rod 6 is installed on the outside of the connecting member 2 through the toothed shafts 8.

[0025] The teeth on the outer side of the toothed shaft 8 correspond to the engagement groove 3, so that the teeth on the outer side of the toothed shaft 8 can be interlaced and connected with the engagement groove 3, ensuring that the connecting rod 6 will not rotate arbitrarily. The fixing disc 7 is used to fix it on the outer side of the connecting piece 2.

[0026] A connecting shaft 9 is installed at the other end of the connecting rod 6, and a drain hole 10 is provided through the outer side of the connecting shaft 9;

[0027] The connecting shaft 9 serves as a rotatable connection, allowing the gyroscope rotor to rotate and be installed inside the gyroscope. The outer side of the connecting shaft 9 has an annular groove, providing space for lubricating oil and also providing a location for the opening of the drain hole 10. Multiple drain holes 10 are provided to provide space for the added lubricating oil to drain.

[0028] One end of the connecting shaft 9 is provided with a circular groove 11, and a threaded inlet hole 12 is provided on the inner wall of the circular groove 11, and the threaded inlet hole 12 is connected to the drain hole 10 through the groove.

[0029] The circular groove 11 provides space for the installation of the threaded plug 13, ensuring that the threaded plug 13 does not protrude from one side of the connecting shaft 9 after installation. The threaded inlet hole 12 provides space for adding lubricating oil. When lubricating oil needs to be added, the threaded plug 13 is rotated out to open the threaded inlet hole 12. Then, the lubricating oil is added into the interior through the threaded inlet hole 12. Finally, the lubricating oil is discharged to the outside of the connecting shaft 9 through the through-connected drain hole 10, thereby making the lubrication of the connecting shaft 9 more convenient and uniform.

[0030] A threaded plug 13 is installed inside the circular groove 11 through a threaded entry hole 12;

[0031] The threaded plug 13 is threadedly connected to the threaded inlet hole 12 via an external thread, thereby sealing the threaded inlet hole 12 and preventing lubricating oil from flowing out of the threaded inlet hole 12.

[0032] The working principle is as follows: First, the first connecting component 4 and the second connecting component 5 are installed on both sides of the gyroscope rotor body 1. When installing the first connecting component 4 and the second connecting component 5, one end of the connecting rod 6 is installed by connecting the toothed shaft 8 and the engagement groove 3. The toothed shaft 8 and the engagement groove 3 are interlocked. Then, the fixing disc 7 is fixed by screws, thereby improving the stability between the gyroscope rotor body 1 and the first connecting component 4 and the second connecting component 5. The threaded plug 13 can be rotated and disassembled, allowing the added lubricating oil to be discharged through the drain hole 10, making it more convenient and even to add lubricating oil to the connecting shaft 9.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
