[0029] As Figures 1 to 5 shown: A gusset plate structure includes:
[0030] Two connecting plates 1, and the two connecting plates 1 are fixedly arranged on the embedded part;
[0031] A lug 2, the lug 2 is arranged between the two connecting plates 1, and a spherical plain bearing 21 is arranged inside the lug 2;
[0032] A pin shaft 3, the pin shaft 3 passes through the two connecting plates 1 and the spherical plain bearing 21, and an oil injection channel 31 is arranged inside the pin shaft 3. One end of the oil injection channel 31 is located at the spherical plain bearing 21, and the other end is located at the end of the pin shaft 3. Oil can be injected into the spherical plain bearing 21 through the oil injection channel 31.
[0033] The lug 2 is located between two connecting plates 1, and the spherical plain bearing 21 is embedded in the lug 2. As a rotating component, the spherical plain bearing 21 allows relative rotation between the lug 2 and the connecting plate 1, enabling better adaptation to external movements and force transmission. The pin shaft 3 passes through the two connecting plates 1 and the spherical plain bearing 21, playing a role in connection and fixation. The key lies in the design of an oil injection channel 31 inside the pin shaft 3. This channel can directly lead to the spherical plain bearing 21. One end of the oil injection channel 31 is located at the spherical plain bearing 21, and the other end extends to the end of the pin shaft 3. The advantage of this design is that without disassembling the entire gusset plate structure or the spherical plain bearing 21, the spherical plain bearing 21 can be easily lubricated through the end of the pin shaft 3, maintaining lubrication and preventing rusting and jamming.
[0034] Through the oil injection channel 31 inside the pin shaft 3, the spherical plain bearing 21 can be easily lubricated, reducing the workload of daily maintenance. The design of the oil injection channel 31 can ensure that the spherical plain bearing 21 maintains sufficient lubrication, reducing friction and minimizing problems such as rusting and jamming caused by lack of lubrication. Regular lubrication can extend the service life of the spherical plain bearing 21 and the pin shaft 3, reduce the replacement frequency, and improve the reliability of the system.
[0035] In this embodiment, there are two oil injection channels 31. The oil injection channel 31 includes an oil injection port 311 and an oil outlet 312. The two oil injection ports 311 are respectively located at both ends of the pin shaft 3, and the two oil outlets 312 are respectively located at both ends of the spherical plain bearing 21.
[0036] The two oil injection ports 311 are located at both ends of the pin shaft 3, so that lubricating oil can be injected from either end under different maintenance conditions, increasing the flexibility and convenience of the oil injection operation. The two oil outlets 312 are located at both ends of the spherical plain bearing 21, ensuring that the lubricating oil can be evenly distributed over the entire inner surface of the spherical plain bearing 21 to achieve full lubrication. When the lubricating oil is injected through the oil injection port 311, it will reach the oil outlet 312 along the oil injection channel 31. The lubricating oil enters both sides of the spherical plain bearing 21 from the two oil outlets 312 respectively, keeping the entire spherical plain bearing 21 evenly lubricated. This can prevent problems such as wear or jamming caused by local oil shortage.
[0037] The design of the double oil injection channel 31 ensures more uniform distribution of the lubricating oil, effectively covering all working areas of the spherical plain bearing 21, further reducing friction and minimizing local rusting or jamming phenomena that may occur during long-term use.
[0038] Among them, the two oil injection ports 311 are respectively provided with hexagonal plugs 313 connected by threads, and the hexagonal plugs 313 block the oil injection ports 311.
[0039] The oil filling port 311 is connected to the hexagonal plug 313 by threads, enabling the plug to be firmly fixed on the oil filling port 311, not easily falling off or loosening, and ensuring the sealing performance and protection effect of the oil filling passage 31. The hexagonal plug design facilitates the use of common tools such as wrenches to easily rotate the plug for disassembly and assembly, improving the convenience of the oil filling operation. After the oil filling is completed, the hexagonal plug 313 can effectively block the oil filling port 311, preventing external dust, dirt, or moisture from entering the oil filling passage 31, and ensuring the long-term cleanliness and lubrication effect of the passage and the spherical plain bearing 21.
[0040] As a preference of the above embodiment, gaskets 4 and sealing rings 5 are respectively arranged between the two connecting plates 1 and the spherical plain bearing 21;
[0041] Both ends of the gasket 4 are respectively in contact with the connecting plate 1 and the lug 2, covering the spherical plain bearing 21;
[0042] The sealing ring 5 is arranged between the gasket 4 and the lug 2 to seal the spherical plain bearing 21.
[0043] The gasket 4 is arranged between the two connecting plates 1 and the spherical plain bearing 21, covering the spherical plain bearing 21, and both ends are respectively in contact with the connecting plate 1 and the lug 2. This design can provide an additional protective layer for the spherical plain bearing 21, reducing the intrusion of external substances. The gasket 4 covers the outer surface of the spherical plain bearing 21, preventing external dust, particles, liquids, etc. from entering the interior of the spherical plain bearing 21, and further protecting the spherical plain bearing 21 from environmental influences.
[0044] The sealing ring 5 is arranged between the gasket 4 and the lug 2 to form an additional sealing barrier. The sealing ring 5 is elastically compressed to ensure that there are no leakage gaps at the connecting part of the spherical plain bearing 21, maximizing the isolation from the external environment. Further improving the sealing performance of the spherical plain bearing 21, preventing lubricating oil from flowing out through the gaps, and preventing moisture or other corrosive substances from entering the area of the spherical plain bearing 21.
[0045] As a preference of the above embodiment, an oil groove 41 is arranged on the inner diameter of the gasket 4, and the oil groove 41 is communicated with the oil filling passage 31.
[0046] Wherein, at least one oil outlet hole 42 is arranged at one end of the gasket 4 close to the spherical plain bearing 21. One end of the oil outlet hole 42 is communicated with the oil groove 41, and the other end is communicated with the space between the gasket 4 and the spherical plain bearing 21.
[0047] An oil groove 41 is designed on the inner diameter of the gasket 4, and the oil groove 41 is connected to the oil injection channel 31 inside the pin shaft 3. In this way, when lubricating oil is injected through the pin shaft 3, the oil groove 41 can serve as a distribution channel for the lubricating oil and transfer the lubricating oil to the inner side of the gasket 4. At least one oil outlet hole 42 is provided at one end of the gasket 4 close to the spherical plain bearing 21. One end of the oil outlet hole 42 communicates with the oil groove 41, and the other end communicates with the gap between the gasket 4 and the spherical plain bearing 21. The oil outlet hole 42 ensures that the lubricating oil can flow from the oil groove 41 to the surface of the spherical plain bearing 21, thereby covering the working surface of the spherical plain bearing 21 and providing sufficient lubrication.
[0048] The combined design of the oil groove 41 and the oil outlet hole 42 ensures that the lubricating oil can smoothly reach the surface of the spherical plain bearing 21 from the oil injection channel 31. This distribution method can more effectively cover all important parts of the spherical plain bearing 21, reducing friction and wear. The lubricating oil acts directly on the surface of the spherical plain bearing 21 through the oil outlet hole 42, avoiding unnecessary oil consumption and ensuring that the key parts are fully lubricated.
[0049] In this embodiment, the sealing ring 5 is a V-shaped sealing ring 5. The V-shaped sealing ring 5 can better adapt to the slight changes between the gasket 4 and the lug 2, ensuring that the seal around the spherical plain bearing 21 remains stable and providing effective sealing even under high-pressure or high-load conditions.
[0050] As a preference of the above embodiment, a circlip 22 is provided between the spherical plain bearing 21 and the lug 2, and the circlip 22 restricts the separation of the spherical plain bearing 21 from the lug 2. The circlip 22 provides an additional limiting function between the spherical plain bearing 21 and the lug 2, ensuring that the spherical plain bearing 21 will not become loose or fall off due to long-term use. This not only improves the structural stability but also enhances the anti-vibration ability of the system.

What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
