Description

Technical Field

[0001] This utility model belongs to the field of universal joint bearing technology, and specifically relates to a gyroscope bearing for universal joints. Background Technology

[0002] The gyroscope bearing for the gimbal is a key component in the gyroscope used to support the gimbal. It needs to have low friction torque and vibration resistance to ensure the accuracy and stability of the gyroscope. Common types, such as the NSK imported bearing series, reduce the starting torque through raceway precision machining and special cage design, and improve vibration resistance by applying a surface coating hardening treatment to the raceway, thus adapting to the complex working environment of the gyroscope.

[0003] However, existing gyroscope bearings still have some shortcomings. Gyroscope bearings are generally divided into two parts, consisting of an outer bearing and an inner bearing, which are usually connected to each other by a connecting shaft. The overall bearing cannot achieve relatively quick disassembly and assembly capabilities. When subsequent maintenance of the gyroscope bearing is required, the difficulty in disassembling it will reduce the efficiency of subsequent maintenance. Utility Model Content

[0007] As a preferred technical solution, a retaining spring that matches the second retaining block is installed on the inner side of the circular groove. The other side of the second retaining block is engaged with one side of the retaining spring. The second retaining block is engaged with the inner side of the circular groove by the retaining spring. A sealing block is fixedly connected to one side of the first retaining block. The sealing block covers one side of the first retaining groove. A protrusion is fixedly connected to one side of the sealing block. The protrusion has an arc-shaped corner.

[0008] As a preferred technical solution, a second rubber pad is fixedly connected to one side of the second connecting shaft. The thickness of the second rubber pad is five millimeters. The first slot is located on the inner side close to the second rubber pad. One side of the second rubber pad is in contact with the other side of the baffle.

[0009] As a preferred technical solution, the top of the mounting plate is provided with positioning holes, which penetrate the mounting plate and are located on the four sides near the corners of the top of the mounting plate.

[0010] As a preferred technical solution, the bottom end of the mounting plate is provided with a groove, and an anti-slip pad is fixedly connected to the inner side of the groove. The anti-slip pad covers the inner side of the groove, and the bottom end of the anti-slip pad is on the same horizontal line as the bottom end of the mounting plate.

The screw hole is located on the inner side close to the first rubber pad, and the bottom end of the first rubber pad is in contact with the top end of the mounting plate.

[0013] In summary, the present invention has the following main advantages:

[0014] In use, the second locking block can be inserted into the circular groove using the first locking block. The second locking block is adjusted to a non-corresponding angle with the second locking groove, thus locking the second locking block into the inner side of the circular groove to prevent the baffle from falling off. It also effectively limits the installation of the inner bearing.

An outer bearing 9 is mounted on the top of the mating plate 3. A first connecting shaft 10 is mounted on the inner bottom of the outer bearing 9. An inner bearing 11 is mounted on the inner wall of the outer bearing 9. A through hole 14 is formed on one side of the inner bearing 11. A second connecting shaft 12 is inserted into the inner side of the through hole 14. A baffle 13 is engaged on one side of the second connecting shaft 12. A first slot 15 is formed on one side of the baffle 13, extending into the interior of the second connecting shaft 12. A second slot 16 is formed on the inner wall of the first slot 15. A circular groove 17 is formed on the inner side of the first slot 15. A first locking block 20 is engaged on the inner side of the first slot 15. A component is fixedly connected to the outer side of the first locking block 20. The second locking block 21, which matches the second locking slot 16, is engaged inside the circular groove 17. In use, the second locking block 21 is inserted into the circular groove 17 through the first locking slot 15 and the second locking slot 16. Then, the second locking block 21 is adjusted to a non-corresponding angle with the second locking slot 16, so that the second locking block 21 can be engaged inside the circular groove 17 to prevent the baffle 13 from falling off. At the same time, it can also effectively limit the installation of the inner bearing 11. When the inner bearing 11 needs to be removed later, the second locking block 21 is adjusted to a corresponding angle with the second locking slot 16, and then the first locking block 20 can be pulled out directly. This can facilitate the quick disassembly and assembly of the inner bearing 11 and also effectively improve the subsequent maintenance efficiency of the inner bearing 11 or the outer bearing 9.

[0024] refer to Figures 1 to 6A retaining spring 18 matching the second retaining block 21 is installed on the inner side of the circular groove 17. The other side of the second retaining block 21 is engaged with one side of the retaining spring 18. The second retaining block 21 is engaged with the inner side of the circular groove 17 through the retaining spring 18. A sealing block 22 is fixedly connected to one side of the first retaining block 20. The sealing block 22 covers one side of the first retaining groove 15. A protrusion 23 is fixedly connected to one side of the sealing block 22. The protrusion 23 has an arc-shaped corner. Due to the presence of the retaining spring 18, the retaining spring 18 can engage the second retaining block 21 at the position, thereby effectively improving the stability of the engagement of the second retaining block 21 at the position, and also effectively improving the stability of the engagement of the baffle 13 at the position.

[0025] refer to Figures 1 to 4 A second rubber pad 19 is fixedly connected to one side of the second connecting shaft 12. The thickness of the second rubber pad 19 is five millimeters. The first slot 15 is located on the inner side close to the second rubber pad 19. One side of the second rubber pad 19 is in contact with the other side of the baffle 13. Due to the presence of the second rubber pad 19, the second rubber pad 19 has good anti-slip ability and rubber elasticity. When the second locking block 21 is engaged, the baffle 13 will be pressed down accordingly. After the second locking block 21 is engaged, the rebound of the second rubber pad 19 can make the second locking block 21 engage more tightly, thereby further improving the stability of the baffle 13 position engagement.

[0026] refer to Figure 1 The top of the mounting plate 1 is provided with a positioning hole 2, which penetrates the mounting plate 1. The positioning hole 2 is located on the four sides near the corner of the top of the mounting plate 1. Because of the positioning hole 2, the user can use a positioning part that matches the positioning hole 2 to fix the mounting plate 1 on the universal bracket, so that the user can position the overall bearing structure.

[0027] refer to Figure 5 The bottom end of the mounting plate 1 is provided with a groove 7, and an anti-slip pad 8 is fixedly connected to the inner side of the groove 7. The anti-slip pad 8 covers the inner side of the groove 7, and the bottom end of the anti-slip pad 8 is on the same horizontal line as the bottom end of the mounting plate 1. Due to the presence of the anti-slip pad 8, the anti-slip pad 8 can effectively improve the friction of the bottom end of the mounting plate 1, thereby making the position of the mounting plate 1 more stable and preventing it from sliding or shifting.

[0028] refer to Figure 5 and Figure 6 The bottom end of the mounting plate 1 has a screw hole 4 that extends into the interior of the mating plate 3. A bolt 5 is threaded into the inside of the screw hole 4. The top of the bolt 5 is threaded into the interior of the mating plate 3 through the screw hole 4. The mating plate 3 is threaded into the top of the mounting plate 1 through the screw hole 4 and the bolt 5. Due to the presence of the bolt 5, the bolt 5 can be screwed in to effectively fix the position of the mating plate 3 and prevent the mating plate 3 from shifting. When the mating plate 3 needs to be disassembled later, the bolt 5 can be unscrewed.

[0029] refer to Figure 6 The bottom end of the mating plate 3 is fixedly connected to a first rubber pad 6, which is five millimeters thick. The screw hole 4 is located on the inner side close to the first rubber pad 6. The bottom end of the first rubber pad 6 is in contact with the top end of the mounting plate 1. Due to the presence of the first rubber pad 6, the first rubber pad 6 has good anti-slip ability and rubber cushioning ability. While improving the positional stability of the mating plate 3, it can also effectively improve the stability of the positional limitation of the mating plate 3.

[0030] Operating principle and advantages: In use, the second locking block 21 is fed into the circular groove 17 through the first locking groove 15 and the second locking groove 16. Then, the second locking block 21 is adjusted to a non-corresponding angle with the second locking groove 16, thereby locking the second locking block 21 into the inner side of the circular groove 17 to prevent the baffle 13 from falling off. It also effectively limits the installation of the inner bearing 11. When the inner bearing 11 needs to be removed later, the second locking block 21 is adjusted to a corresponding angle with the second locking groove 16, and then the first locking block 20 can be directly pulled out. This achieves the effect of convenient and quick disassembly and assembly of the inner bearing 11, and also effectively improves the subsequent maintenance efficiency of the inner bearing 11 or the outer bearing 9. Due to the presence of the retaining spring 18, the retaining spring 18 can provide secondary locking of the second locking block 21, thereby effectively improving the stability of the locking of the second locking block 21, and also effectively improving the stability of the locking of the baffle 13. Due to the presence of the second rubber pad 19, which has good anti-slip ability and rubber elasticity, when the second locking block 21 is engaged, the baffle 13 will be pressed down accordingly. After the second locking block 21 is engaged, the rebound of the second rubber pad 19 can make the second locking block 21 engage more tightly, thereby further improving the stability of the baffle 13 position engagement. Due to the opening of the positioning hole 2, the user can use the positioning part that matches the positioning hole 2 to fix the mounting plate 1 on the universal bracket, so that the user can position the overall bearing structure. Due to the presence of the anti-slip pad 8, the anti-slip pad 8 can effectively increase the friction at the bottom of the mounting plate 1, thereby making the position of the mounting plate 1 more stable and preventing it from sliding or shifting. Due to the presence of the bolt 5, the screwing in of the bolt 5 can effectively fix the position of the mating plate 3 to prevent the mating plate 3 from shifting. When the mating plate 3 needs to be disassembled later, the bolt 5 can be unscrewed.
