Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0022] like Figures 1-5As shown, an embodiment of the present invention provides a worm gear transmission box oiling mechanism including a worm gear transmission box body 100, an oiling mechanism body 1, a filtering mechanism 2, an anti-backflow mechanism 3, and a viewing mechanism 4. The worm gear transmission box body 100 has an oil inlet on its top wall panel. The oiling mechanism body 1 includes an oiling shell 11 mounted on the oiling port of the worm gear transmission box body 100, and mounting components at the bottom and a sealing component at the top of the oiling shell 11. The filtering mechanism 2 includes a filter screen 21 mounted inside the oiling shell 11. The anti-backflow mechanism 3 includes a flap 31 rotatably mounted inside the oiling shell 11, and the flap 31 is positioned below the filter screen 21. The viewing mechanism 4 includes a viewing window 41 embedded in the side wall of the oiling shell 11.

[0023] When using this worm gear transmission oil filling mechanism, the oil filling housing 11 is first installed onto the oil filling hole on the top wall panel of the worm gear transmission body 100 using the mounting assembly. The sealing assembly at the top of the oil filling housing 11 is then opened, allowing lubricating oil to be poured into it. The lubricating oil flows within the housing and is filtered by the filter screen 21 to remove impurities introduced during filling. The filtered lubricating oil falls onto the flap 31, which flips under the action of the lubricating oil, allowing it to continue flowing downwards through the oil filling hole into the worm gear transmission. The oil level in the worm gear transmission can be observed through the viewing window 41 during filling, making it easy to monitor the oil level and preventing underfilling or overfilling. This device significantly improves maintenance efficiency and extends the service life of the transmission.

[0024] like Figures 2-4 As shown, the oil filling shell 11 is designed in the shape of a funnel with a large opening at the top and a small opening at the bottom, which makes it easy to pour oil in and improves the efficiency of oil filling.

[0025] like Figures 2-4 As shown, the mounting assembly includes a mounting base 12, a sealing ring 13, and multiple fixing screws 14. The mounting base 12 is integrally formed on the bottom of the oil filling housing 11.

[0026] like Figures 2-4 As shown, the sealing ring 13 is disposed between the top wall plate of the worm gear transmission housing body 100 and the mounting base 12. Multiple fixing screws 14 are threadedly connected to the mounting base 12 and the top wall plate of the worm gear transmission housing body 100 at equal intervals. The mounting base 12 is fixed to the worm gear transmission housing body 100 by the multiple fixing screws 14, and the sealing ring 13 ensures a tight seal between the oil filling housing 11 and the worm gear transmission housing body 100 after installation.

[0027] like Figures 2-4As shown, the sealing assembly includes a sealing cap 15 threaded to the top of the oil filling housing 11, and a sealing gasket 16 installed inside the sealing cap 15. The threaded connection of the sealing cap 15 makes it easy to open the upper port of the oil filling housing 11 during oil filling, while the sealing gasket 16 ensures that the sealing cap 15 is tightly sealed on the oil filling housing 11.

[0028] Preferably, the filter screen 21 is made of stainless steel, and a magnetic mounting ring is provided at the bottom edge of the filter screen 21. This ensures that when the filter screen 21 filters lubricating oil, the lubricating oil will not cause corrosion to the filter screen 21, thus improving the service life of the filter screen 21.

[0029] like Figures 2-4 As shown, the filter mechanism 2 also includes a magnetic ring 22 and a handle 23. The magnetic ring 22 is fixed to the inner wall of the oil filling shell 11. The filter screen 21 is magnetically attracted to the magnetic ring 22 through the mounting ring at the bottom. The handle 23 is fixedly connected to the filter screen 21. The magnetic attraction of the magnetic ring 22 makes it easy to fix the filter screen 21 and disassemble it, so as to facilitate the cleaning of the filter screen 21.

[0030] like Figures 2-5 As shown, the anti-backflow mechanism 3 also includes a pair of rotating shafts 32, a pair of knobs 33, a limiting block 34, and a guide plate 35. The pair of rotating shafts 32 are symmetrically fixed to the side wall of the flap 31. The end of the pair of rotating shafts 32 away from the flap 31 is rotatably connected to the side wall of the oil filling shell 11 through the shafts. The pair of knobs 33 are respectively fixedly connected to the ends of the rotating shafts 32 located on the outside of the oil filling shell 11. When the center of the flap 31 is offset by the rotating shafts 32, it can flip over, so that the lubricating oil injected into the oil filling shell 11 can be transported to the transmission box by flipping. At the same time, when the lubricating oil in the transmission box comes out during oil filling, the flap 31 will block the lubricating oil to prevent backflow and leakage. The knobs 33 allow the operator to rotate the flap 31 from the outside of the oil filling shell 11, so that manual operation can be performed if the automatic rotation of the flap 31 fails.

[0031] like Figures 2-5 As shown, the limiting block 34 is fixed to the inner wall of the oil filling shell 11 and is located at the bottom of one side of the flap 31. The guide plate 35 is fixedly connected to the inner wall of the oil filling shell 11 on the same side where the limiting block 34 is fixed, in a downward inclined manner. Under the restriction of the limiting block 34, the flap 31 installed in the oil filling shell 11 can only flip to one side, realizing the directional delivery of lubricating oil. The lubricating oil filtered by the filter screen 21 is delivered to the flippable side of the flap 31 after being guided by the guide plate 35, so that the lubricating oil acts on the rotatable side of the flap 31, causing the flap 31 to flip.

[0032] Preferably, the sidewalls of the flap 31, guide plate 35 and viewing window 41 are all provided with an anti-oil nano-coating, so that when the lubricating oil comes into contact with the flap 31, guide plate 35 and viewing window 41, the lubricating oil will not adhere to it, ensuring that the inner surface of the viewing window 41 is clean, so as to facilitate the observation of the oil level.

[0033] In use, the mounting base 12 is first fixed to the worm gear transmission housing body 100 using multiple fixing screws 14. The oil filling shell 11 is then installed onto the oil filling hole on the top wall panel of the worm gear transmission housing body 100. The sealing cover 15 is removed from the oil filling shell 11, allowing lubricating oil to be poured in. The lubricating oil flows within the oil filling shell 11 and is filtered by the filter screen 21 to remove impurities introduced during oil filling. The filtered lubricating oil falls onto the guide plate 35, which guides it to the rotatable side of the flap 31. The flap 31 flips under the action of the lubricating oil, allowing it to continue flowing downwards through the oil filling hole into the worm gear transmission housing. The oil level in the worm gear transmission housing can be observed through the viewing window 41, facilitating easy monitoring and preventing under- or over-filling. This device significantly improves maintenance efficiency and extends the service life of the transmission housing.

[0034] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description.
