Description

Technical Field

[0001] This utility model relates to the field of gear technology, specifically to a gear with lubrication function. Background Technology

[0002] Gears are mechanical parts with regular toothed edges. They transmit mechanical motion and change speed and torque through meshing with other gears or racks. They are widely used in various mechanical equipment to ensure efficient power transmission and precise control.

[0003] Existing gears with lubrication functions lack an effective self-regulating mechanism for lubricant supply. When gears rotate at high speeds, centrifugal force causes excessive lubricant to be thrown out, resulting in waste and oil pollution of the surrounding environment. When gears are stationary or running at low speeds, lubricant is difficult to actively deliver to the meshing parts, leading to insufficient lubrication and increased gear wear. In terms of impurity handling, metal shavings generated by tooth surface friction during long-term operation tend to accumulate in the oil reservoir. Due to the lack of a targeted cleaning structure, the shavings will enter the meshing area with the lubricant circulation, further aggravating wear and even causing gear jamming and other malfunctions. Summary of the Invention

[0004] In view of the problems existing in the current type of gear with lubrication function, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a gear with a lubrication function, which solves the problems of existing lubrication gears that cannot adjust the lubricating oil supply themselves, are prone to oil leakage and contamination at high speeds and have insufficient lubrication at low speeds, and have internal metal debris deposits that are difficult to clean.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A gear with lubrication function includes a gear body, a guide groove is formed on the outer ring surface of the gear body and an oil guide bead is slidably connected thereto, an oil storage tank is formed in the cavity of the gear body, and a plurality of capillary oil guide hole groups are formed in the cavity of the gear body, and an oil guide fiber is fixedly connected in each capillary oil guide hole group.

[0008] The gear body has a threaded oil inlet on its side wall and a sealing clip is threadedly connected to it. One end of the sealing clip is fixedly connected to a debris magnetic block through an opening. The oil guide bead includes a copper base layer, an oleophilic layer is fixedly connected to the surface of the copper base layer, an anti-corrosion layer is fixedly connected to the surface of the oleophilic layer, and multiple oil-absorbing micropores are opened on the surface of the oil guide bead.

[0009] According to the claim, a gear with lubrication function is characterized in that the oil-guiding fiber is polyester fiber or aramid fiber, and the fiber porosity is 60-70% and the fiber diameter is 5-10 μm.

[0010] Preferably, the sealing clip includes a threaded section, a silicone plug is fixedly connected to the bottom plate of the threaded section, and a torsion plate is fixedly connected to the top of the threaded section.

[0011] Preferably, the oleophilic layer is a molybdenum disulfide coating with a thickness of 0.1-0.5 μm.

[0012] Furthermore, the anti-corrosion layer is a fluorocarbon coating with a thickness of 0.2-0.8 μm.

[0013] Preferably, the flow channel is provided with a wear-resistant and friction-reducing graphene coating, and the coating thickness is 0.3-1μm.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model utilizes the centrifugal drive of the set guide groove and the guide oil ball, combined with the capillary action of the capillary guide oil hole group and the guide oil fiber, to achieve adaptive supply of lubricating oil under all speed conditions.

[0017] 3. This utility model utilizes the synergistic design of the multi-layer coating (oil-loving layer and anti-corrosion layer) of the oil guide beads and the wear-resistant coating of the guide groove to reduce the frictional resistance between components by more than 35%, reduce frictional heat generation and lubricating oil oxidation, and at the same time improve the corrosion resistance of the oil guide beads and the wear resistance of the guide groove, so that the reliable running time of the gear under harsh working conditions is extended to 3 times that of the traditional structure.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a gear with a lubrication function.

[0027] This utility model provides, for example Figure 1-4 The gear shown includes a gear body 1, a guide groove 2 is provided on the outer ring surface of the gear body 1 and an oil guide bead 3 is slidably connected thereto, an oil storage tank 4 is provided in the cavity of the gear body 1, and a plurality of capillary oil guide hole groups 5 are provided in the cavity of the gear body 1, and an oil guide fiber 6 is fixedly connected in each capillary oil guide hole group 5.

[0028] The gear body 1 has a threaded oil inlet 7 on its side wall, and a sealing clamp 8 is threadedly connected to it. One end of the sealing clamp 8 is fixedly connected to a debris magnetic block 9 through an opening. The oil guide bead 3 includes a copper base layer 10, an oleophilic layer 11 is fixedly connected to the surface of the copper base layer 10, and an anti-corrosion layer 12 is fixedly connected to the surface of the oleophilic layer 11. The surface of the oil guide bead 3 has multiple oil suction micropores 13. Utilizing the design of the guide groove 2 and the oil guide bead 3, the centrifugal force drives the oil guide bead 3 to slide along the guide groove 2 when the gear rotates, realizing the directional delivery of lubricating oil. The combination of the set capillary oil guide hole group 5 and the oil guide fiber 6 forms a capillary effect, enabling the lubricating oil to achieve adaptive flow at different speeds. This solves the problems of high-speed oil leakage and insufficient low-speed oil supply in the prior art, increasing the lubricating oil utilization rate by more than 30% and reducing the gear wear rate by 45%. The threaded connection structure of the threaded oil inlet 7 and the sealing clamp 8 further enhances the lubricating oil's effectiveness. To ensure convenient and reliable oil filling and effectively prevent lubricating oil leakage, the system utilizes a magnetic debris-absorbing block 9 to continuously adsorb metal debris during oil filling and lubricating oil circulation, reducing the impurity content in the system by more than 60%, significantly reducing secondary wear caused by debris, and extending gear life by more than 2 times. The copper base layer 10 provides structural support, and the oleophilic layer 11 enhances the adsorption capacity of lubricating oil, improving oil guiding efficiency by 25%. The anti-corrosion layer 12 effectively resists chemical corrosive media in the lubricating oil and protects the internal structure of the oil guiding bead 3. The oil-absorbing micropores 13 further expand the contact area of ​​lubricating oil, achieving efficient storage and release of lubricating oil, and maintaining stable oil supply capacity even at low speeds. This solves the problems of existing lubricating gears that cannot adjust their lubricating oil supply, resulting in easy oil leakage and contamination at high speeds and insufficient lubrication at low speeds, as well as the difficulty in cleaning internal metal debris deposits.

[0029] To achieve precise fuel supply across the entire speed range, such as Figure 2 and 3 As shown, the oil-guiding fiber 6 is made of polyester or aramid fiber, with a porosity of 60-70% and a fiber diameter of 5-10μm. The oil-guiding fiber 6, made of aramid fiber, has good oleophilic properties and mechanical strength. The porosity is controlled at 60-70% to achieve the best balance between capillary force and oil permeability. The fiber diameter of 5-10μm ensures that the oil transmission channel is unobstructed while preventing impurities from clogging it. This increases the delivery volume of lubricating oil by 40% at low speeds and automatically limits the flow by 20% at high speeds, achieving precise oil supply across the entire speed range.

[0030] To enhance the sealing effect and facilitate disassembly, oil is injected, such as... Figure 1 and 3As shown, the sealing clip 8 includes a threaded section 14, a silicone plug 15 is fixedly connected to the base plate of the threaded section 14, and a torsion plate 16 is fixedly connected to the top of the threaded section 14. The engagement of the threaded section 14 with the threaded oil inlet 7 provides a reliable mechanical seal. The silicone plug 15 forms a secondary seal after the threads are tightened. The double sealing structure improves the sealing reliability to 99.8%. The torsion plate 16 increases the operating torque, making the installation and removal of the sealing clip 8 more convenient and improving maintenance efficiency by 50%.

[0031] To reduce resistance while improving transmission efficiency, such as Figure 4 As shown, the oleophilic layer 11 is a molybdenum disulfide coating with a thickness of 0.1-0.5 μm. The molybdenum disulfide coating has an extremely low coefficient of friction (0.03-0.06) and good oleophilic properties. The thickness is controlled at 0.1-0.5 μm, which can ensure the integrity of the coating while avoiding affecting the overall dimensional accuracy of the oil guide bead 3. This reduces the rolling resistance of the oil guide bead 3 in the guide groove 2 by 35% and improves the lubricating oil transmission efficiency by 28%.

[0032] To reduce frictional heat generation between the oil guide bead 3 and the guide groove 2, such as Figure 4 As shown, the anti-corrosion layer 12 is a fluorocarbon coating with a thickness of 0.2-0.8μm. The fluorocarbon coating has excellent chemical stability and weather resistance, which can effectively resist the corrosion of additives, moisture and oxidation products in lubricating oil. The thickness of 0.2-0.8μm can form a continuous and dense protective film, which extends the corrosion resistance life of the oil guide bead 3 under harsh working conditions to more than 3 times that of the traditional structure.

[0033] To reduce frictional heat generation between the oil guide bead 3 and the guide groove 2, such as Figure 1-3 As shown, the guide channel 2 is provided with a wear-resistant and friction-reducing graphene coating with a thickness of 0.3-1μm. The graphene coating has extremely high hardness (20-30GPa) and extremely low coefficient of friction (0.05-0.1). The thickness of 0.3-1μm can significantly improve the wear resistance of the guide channel 2, reduce the wear rate of the guide channel 2 by 70%, and at the same time reduce the frictional heat generated between the oil guide beads 3 and the guide channel 2, reduce the oxidation rate of the lubricating oil, and extend the service life of the lubricating oil by more than 20%.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
