[0026] An embodiment of the utility model provides a gear transmission structure.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5, comprising a gear box 1, wherein a first rotating shaft 11 is rotatably connected to the lower part of the gear box 1, one end of the first rotating shaft 11 is fixedly connected to a motor 12, a main gear 13 is sleeved on the first rotating shaft 11, a second rotating shaft 14 is rotatably connected to the upper part of the gear box 1, a slave gear 15 is sleeved on the second rotating shaft 14, a lubricating component (2) for reducing the wear of the main gear 13 and the slave gear 15 is provided on the top of the gear box 1, the main gear 13 and the slave gear 15 are meshed, and the lubricating component (2) comprises a connecting port 21 opened at the top of the gear box 1, a lubrication box 22 connected to the connecting port 21, an oil outlet 23 opened at the bottom of the lubrication box 22, a roller 24 connected to the oil outlet 23, and a sponge 2 connected to the outer side of the roller 24 5. A sealing component (3) for sealing the connection port 21 and a scraping component (4) for preventing lubricating oil from remaining. The roller 24 is rotatably connected to the oil outlet 23. The sponge 25 is in contact with the top of the slave gear 15. The motor 12 can drive the main gear 13 to rotate, and then drive the slave gear 15 to rotate. The rotation of the slave gear 15 can drive the sponge 25 and the roller 24 to rotate. The lubricating oil in the lubrication box 22 can be applied to the slave gear 15. Since the roller 24 rotates continuously, the lubrication box 22 can be sucked out and applied to the slave gear 15, and then applied to the main gear 13. The main gear 13 and the slave gear 15 can be lubricated, which can save lubricating oil and avoid waste. The component (4) includes a cover plate 41 connected to the top of the lubrication box 22, a screw rod 42 connected to the top of the cover plate 41, a horizontal plate 43 connected to the bottom of the screw rod 42, an oil scraper frame 44 connected to both sides of the horizontal plate 43, a connecting plate 45 connected to the top of the screw rod 42, a handle 46 connected to the top of the connecting plate 45, and a rotation-stopping component (6) for preventing the oil scraper frame 44 from rotating. The screw rod 42 is screwed to the cover plate 41, and the screw rod 42 is rotatably connected to the horizontal plate 43. The oil scraper frame 44 is in contact with the inner wall of the lubrication box 22. By turning the handle 46, the connecting plate 45 and the screw rod 42 can be driven to rotate, thereby driving the horizontal plate 43 to move, and then driving the oil scraper frame 44 to move. The movement of the oil scraper frame 44 can affect the lubrication box 22. The four inner walls are scraped for oil to prevent lubricating oil residue and avoid lubricating oil waste. The anti-rotation component (6) includes an anti-rotation rod 61 fixedly connected to the two sides of the top of the cross plate 43 and a limit plate 62 fixedly connected to the top of the anti-rotation rod 61. The anti-rotation rod 61 passes through the cover plate 41 and is slidably connected to the cover plate 41. The anti-rotation rod 61 can move synchronously with the cross plate 43 to prevent the cross plate 43 from rotating synchronously with the screw rod 42, and can ensure the stability of the vertical movement of the cross plate 43 and the scraper frame 44. A feeding pipe 411 is fixedly connected to one side of the top of the cover plate 41. The feeding pipe 411 is funnel-shaped. The feeding pipe 411 can be used to add lubricating oil to the lubrication box 22, so as to lubricate the slave gear 15 and the main gear 13.

[0028] When the utility model is in use: first, lubricating oil is added to the lubrication box 22 through the feeding pipe 411, and then when the motor 12 is working, it can drive the first rotating shaft 11 and the main gear 13 to rotate, and then drive the slave gear 15 and the second rotating shaft 14 to rotate, and the sponge 25 contacts the slave gear 15. As the slave gear 15 rotates, the sponge 25 rotates synchronously with the roller 24, and the lubricating oil on the sponge 25 can be applied to the slave gear 15. Since the sponge 25 rotates continuously, the sponge 25 can absorb the lubricating oil in the lubrication box 22 and continuously apply it to the slave gear 15, so as to lubricate the slave gear 15 and the main gear 13. Then, the handle 46 can be rotated, and the handle 46 can drive the connecting plate 45 to rotate. The rotation of the connecting plate 45 can drive the screw 42 to rotate. The rotation of the screw 42 can push the cross plate 43 to move downward. The downward movement of the cross plate 43 can drive the oil scraper frame 44 to move downward. The downward movement of the oil scraper frame 44 can scrape off the lubricating oil remaining on the inner wall of the lubrication box 22 to avoid the waste of lubricating oil.

[0029] Please refer again Figure 1 , Figure 2 , Figure 3 as well as Figure 4 The closing component (3) includes receiving grooves 31 respectively provided on both sides of the connecting port 21, a baffle 32 connected to the receiving groove 31, a groove 33 provided on one side of the receiving groove 31, a guide rod 34 connected to one side of the baffle 32, a spring 35 sleeved on the outside of the guide rod 34, slots 36 respectively provided on both sides of the lubrication box 22, and a moving component (5) for moving the baffle 32, wherein the baffle 32 is slidably connected to the receiving groove 31, the guide rod 34 is slidably connected to the groove 33, the baffle 32 is plugged into the slot 36, and the two ends of the spring 35 are respectively fixedly connected to the baffle 32 and the inner wall of the receiving groove 31. The two baffles 32 can fit together under the push of the spring 35, thereby closing the connecting port 21, preventing foreign matter from entering the gear box 1, and protecting the components in the gear box 1. The two baffles 32 are moved to When moving on both sides, the lubrication box 22 can be inserted into the connecting port 21, which can facilitate lubrication of the main gear 13 and the slave gear 15. The moving component (5) includes a sliding port 51 opened at the top of the storage groove 31 and a push plate 52 fixedly connected to the top of the baffle 32. The push plate 52 is slidably connected to the sliding port 51. Pushing the push plate 52 can facilitate the movement of the baffle 32, thereby exposing the connecting port 21, which is convenient for the subsequent installation of the lubrication box 22 to lubricate the main gear 13 and the slave gear 15. The inner wall of the sliding port 51 is fixedly connected with a sliding rod 511, which passes through the push plate 52 and is slidably connected to the push plate 52. The sliding rod 511 can support and guide the movement of the push plate 52, thereby preventing the push plate 52 from being offset or skewed during the movement, thereby ensuring the stability of the lateral movement of the baffle 32.

[0030] When the utility model is in use: when lubrication is needed, the push plates 52 on both sides are pushed, and the movement of the push plates 52 can drive the baffle plates 32 to move horizontally. The lateral movement of the baffle plates 32 can drive the guide rods 34 to move and squeeze the springs 35 to deform them, and then the lubrication box 22 can be inserted into the connecting port 21, and the push plates 52 are released. The thrust generated by the deformation of the springs 35 can push the baffle plates 32 to be inserted into the slots 36, and the lubrication box 22 can be connected and fixed to the gear box 1, which is convenient for lubricating the main gear 13 and the slave gear 15. When the lubrication is completed, the two push plates 52 are pushed again, which can drive the two baffle plates 32 to move horizontally and disengage from the slots 36, and then the lubrication box 22 can be taken out of the gear box 1, and then the push plates 52 are released, and the springs 35 are reset to push the baffle plates 32 to reset, so that the two baffle plates 32 fit each other, and the connecting port 21 can be closed to prevent foreign matter from entering the gear box 1, and the parts in the gear box 1 can be protected.
