[0039] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0040] Example 1:

[0041] This embodiment provides a non-circular transmission pipe with a built-in oil injection system, characterized in that it includes:

[0042] Pipe body 1, which is provided with an oil inlet 11 and an oil outlet 12;

[0043] A lubrication assembly is installed inside the pipe body 1 and is connected to the oil inlet 11 and the oil outlet 12.

[0044] The cross-section of the pipe body 1 is an equilateral triangle, and the wall between the corners of the pipe body 1 is arc-shaped and is set as arc segment 3. The oil inlet 11 and the oil outlet 12 are formed on the arc segment 3.

[0045] A connection hole 13 is provided on the wall of the pipe body 1 outside the oil inlet 11.

[0046] As can be seen from this embodiment, a special-shaped transmission pipe with a built-in oil injection system includes a pipe body 1 and a lubrication assembly;

[0047] The pipe body 1 is equipped with a lubrication component, which is connected to the oil outlet 12 through the oil inlet 11. This ensures that the lubricating oil or lubricating fluid inside the pipe is always kept in the best flow state, which can effectively reduce the friction between the components in the transmission pipe, reduce wear, extend the service life of the equipment, and improve work efficiency.

[0048] Furthermore, the cross-section of the pipe 1 is an equilateral triangle, and the wall surface between the corners is rounded, which is set as the arc segment 3. This design makes the stress distribution of the pipe 1 more uniform, reduces the possible stress concentration, thereby enhancing the pressure resistance of the pipe 1 and avoiding the pipe 1 from cracking or leaking due to high pressure or overload. In addition, the shape of the arc segment 3 also makes the flow of lubricating oil smoother, reduces the stagnation or dead corners of oil in the pipe, and helps the lubricating oil flow and heat dissipation efficiently.

[0049] Furthermore, the placement of the oil inlet 11 and the oil outlet 12 on the arc segment 3 helps to ensure the uniform distribution and flow of oil. The oil inlet 11 ensures that the lubricating oil is injected smoothly, and the design of the oil outlet 12 ensures that the oil can be effectively discharged, thereby ensuring the smoothness of oil circulation and the continuity of lubrication, and minimizing the accumulation of oil or unnecessary waste.

[0050] Furthermore, the connection hole 13 provided on the outside of the pipe body 1 provides convenient conditions for the maintenance, connection and oil circuit access of the oil injection system. The connection hole 13 allows the pipeline to be effectively connected to external equipment such as oil pumps, filters and other systems, which facilitates the injection, circulation and maintenance of lubricating oil.

[0051] The built-in design of the oil injection device helps to optimize the structural layout and improve space utilization. Its innovative design lies in the triangular tube 1 and the arc wall, which can provide a more stable oil flow and a more efficient lubrication effect, ensuring the smooth operation of the mechanical system.

[0052] Example 2:

[0053] This embodiment provides a non-circular transmission pipe with a built-in oil injection system. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0054] The lubrication components include:

[0055] The first block 21 has a first oil passage 211 provided on it. The first block 21 is located inside the pipe body 1, and the first oil passage 211 corresponds to the oil inlet 11.

[0056] The second block 22 is provided with a second oil passage 221, which corresponds to the oil outlet 12.

[0057] Oil pipe 23 is disposed between the first block 21 and the second block 22, and connects the first oil passage 211 and the second oil passage 221;

[0058] Among them, the first block 21 and the second block 22 are circular and fit with the inner side of the arc segment 3;

[0059] The oil outlet 12 is provided in multiple ways, and the second oil passage 221 corresponds one-to-one with the multiple oil outlets 12.

[0060] As can be seen from this embodiment, the lubrication assembly includes a first plug 21 and a second plug 22;

[0061] The first oil passage 211 is formed inside the first block 21, and the first oil passage 211 corresponds to the oil inlet 11. When in use, lubricating oil is injected into the oil inlet 11, and the oil will enter the system through the first oil passage 211. The corresponding position of the first oil passage 211 and the oil inlet 11 ensures that the lubricating oil can smoothly enter the system and start the lubrication function.

[0062] The second block 22 has a second oil passage 221 formed inside, and the second oil passage 221 corresponds to the oil outlet 12. When in use, the lubricating oil passes through the lubrication system and is discharged through the second oil passage 221. The oil passage corresponds one-to-one with multiple oil outlets 12, which means that the lubricating oil will flow to each part that needs lubrication according to the designed path. The design of multiple oil outlets 12 can ensure that the distribution of lubricating oil is more uniform and improve the lubrication effect.

[0063] The oil pipe 23 is located between the first block 21 and the second block 22, connecting the first oil passage 211 and the second oil passage 221, and serves to connect the oil inlet 11 and the oil outlet 12.

[0064] The lubricating oil can flow from the oil inlet 11 through the oil passage system and finally be released to the parts that need lubrication through multiple oil outlets 12. This flow method can ensure the uniform distribution of lubricating oil, improve the lubrication effect, reduce friction, and reduce system wear.

[0065] The design of this lubrication component ensures that lubricating oil can smoothly enter from the oil inlet 11, be transmitted through the oil passage system, and be distributed to various parts of the system through multiple oil outlets 12. The precise design of the oil pipes 23 and oil passages makes the flow of lubricating oil more efficient, which can improve the lubrication performance of the entire system, reduce friction and wear, extend the service life of the equipment, and ensure the stable operation of the system under high pressure and high temperature conditions.

[0066] Example 3:

[0067] This embodiment provides a non-circular transmission pipe with a built-in oil injection system. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0068] Oil nozzle 4 is connected to oil inlet 11 and extends into first oil passage 211;

[0069] The oil nozzle 4 is threadedly connected to the oil inlet 11 and the first oil passage 211.

[0070] As can be seen in this embodiment, the grease nipple 4 is directly connected to the grease port 11, serving as an extension of the grease port 11. It ensures that the oil during the grease injection process can accurately and stably enter the lubrication system. Through this connection, the grease can smoothly enter the system through the grease nipple 4, providing the necessary amount of lubricating oil.

[0071] Furthermore, the grease nipple 4 extends into the first oil passage 211, ensuring that the lubricating oil injected from the grease port 11 can smoothly enter the first oil passage 211 through the grease nipple 4. This helps to ensure that the path of the lubricating oil flowing into the oil passage is clear and controlled, effectively avoiding oil leakage or poor flow.

[0072] Furthermore, the threaded connection between the grease nipple 4, the grease port 11, and the first oil passage 211 ensures sealing and firmness. The threaded connection can effectively prevent oil leakage during the grease filling process and avoid waste of lubricating oil. In addition, the threaded connection design also allows the grease nipple 4 to be disassembled or replaced when needed, which is convenient for maintenance and cleaning. The threaded connection also ensures the precise fit between the grease nipple 4, the grease port 11, and the first oil passage 211, so that the flow path of lubricating oil is fixed and stable, reducing the problem of unstable oil flow or oil leakage caused by loose or misaligned connections.

[0073] The structure ensures stable flow and precise distribution of lubricating oil through the threaded connection between the oil nozzle 4, the oil inlet 11, and the first oil passage 211. The threaded connection not only provides good sealing to prevent oil leakage, but also ensures the robustness and maintainability of the oil nozzle 4. The design of the oil nozzle 4, which extends into the first oil passage 211, effectively ensures that the lubricating oil can smoothly enter the oil passage system, further optimizing the lubrication effect, reducing system wear, and improving the reliability and durability of the equipment.

[0075] This embodiment provides a non-circular transmission pipe with a built-in oil injection system. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0076] Guide pipe 5 is provided on oil outlet 12 and connected to the second oil passage 221;

[0077] The guide pipe 5 is threadedly connected to the oil outlet pipe 23 and the second oil passage 221.

[0078] As can be seen from this embodiment, the guide pipe 5 is connected to the oil outlet 12, which serves to guide the lubricating oil to the outside of the system or the target part. By guiding the lubricating oil in a specified direction, it can be ensured that the lubricating oil flows out according to the designed path and is accurately distributed to the parts that need lubrication, thereby enhancing the lubrication effect of the system.

[0079] Furthermore, the guide pipe 5 is connected to the second oil passage 221, ensuring that the lubricating oil can be smoothly guided to the outside of the oil outlet 12 or other parts after flowing out of the second oil passage 221 through the guide pipe 5. This helps to ensure the stability of the oil flow and prevent the oil from becoming disordered or leaking during the flow process.

[0080] Furthermore, the threaded connection between the guide pipe 5 and the oil outlet pipe 23 and the second oil passage 221 ensures a firm connection between the components and prevents loosening during operation.

[0081] The design of the guide tube 5 ensures that the lubricating oil can be efficiently and accurately guided to the oil outlet 12 after flowing out from the second oil passage 221, and flow to different parts of the lubrication system as needed. The threaded connection ensures the firmness, sealing and stability of the connection, and avoids oil leakage and poor flow.

[0082] The guide tube 5 not only improves the flow efficiency of lubricating oil, but also helps optimize the lubrication distribution, making the entire lubrication system more efficient, reducing friction and wear, extending the service life of the equipment, and ensuring that the system can still operate stably under high load or high temperature environments.

[0086] The first sealing ring 61 is disposed between the mating surfaces of the oil injection nozzle 4 and the first oil passage 211;

[0087] The second sealing ring 62 is disposed between the mating surfaces of the guide pipe 5 and the second oil passage 221;

[0088] The third sealing ring 63 is disposed between the mating surfaces of the oil pipe 23 and the first oil passage 211 and the second oil passage 221.

[0089] As can be seen from this embodiment, the sealing ring includes a first sealing ring 61, a second sealing ring 62, and a third sealing ring 63;

[0090] The first sealing ring 61 is installed between the mating surfaces of the oil nozzle 4 and the first oil passage 211, thereby sealing the mating surfaces between the oil nozzle 4 and the first oil passage 211 and preventing leakage.

[0091] The second sealing ring is installed between the mating surfaces of the guide pipe 5 and the second oil passage 221, thereby sealing the connection mating surfaces between the guide pipe 5 and the second oil passage 221 and preventing leakage.

[0092] The third sealing ring 63 is disposed between the mating surfaces of the oil pipe 23 and the first oil passage 211 and the second oil passage 221. The third sealing ring 63 seals the mating surfaces of the oil pipe 23 and the first oil passage 211 and the second oil passage 221 to prevent leakage.

[0095] The second block 22 is replaced by a distributor, which is connected to the oil pipe 23 and the guide pipe 5.

[0096] As can be seen from this embodiment, by setting a flow divider to guide the fluid in the oil pipe 23 to enter the guide pipe 5 evenly, it helps to improve the lubrication effect. Furthermore, there is no difference in appearance between the flow divider and the second block 22, therefore, in the attached... Figure 2 The second block 22 in the middle can also be regarded as a diverter.
