[0003] Worm gear reducers primarily achieve speed reduction through the meshing of the worm and worm. However, during meshing, friction causes the worm and worm wheel to heat up. Excessive temperature of the worm and worm wheel can affect their service life. Existing worm gear reducers are not conducive to heat dissipation or have low heat dissipation efficiency. The problem addressed by this device is how to further improve the heat dissipation efficiency of worm gear reducers. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides the following technical solution: a worm gear reducer with heat dissipation, including a mounting frame 1, a housing 8 fixedly mounted in the middle of the top of the mounting frame 1, a storage box 3 fixedly mounted on the left side of the top of the mounting frame 1, a mounting box 5 fixedly mounted on the right side of the top of the mounting frame 1, a drive motor 20 fixedly mounted on the right side of the top of the housing 8, a movable rod 22 fixedly mounted on the drive motor 20 via a rotating shaft at its output end, a worm gear 21 fixedly mounted in the middle of the surface of the movable rod 22, a connecting rod 25 rotatably mounted inside the housing 8, a worm wheel 26 fixedly mounted in the middle of the surface of the connecting rod 25, and the worm gear... 21 is meshed with worm gear 26. A connecting pipe 4 is fixedly installed on the top of the storage box 3, and one end of the connecting pipe 4 is fixedly connected to the right side of the outer casing 8. An oil pump 15 is fixedly installed on the surface of the connecting pipe 4. An installation pipe 24 is fixedly installed on the right side of the storage box 3. A filter box 23 is fixedly installed at one end of the installation pipe 24, and the filter box 23 is fixedly connected to the left side of the outer casing 8. A servo motor 18 is fixedly installed inside the installation box 5. A rotating fan blade 19 is fixedly installed on the servo motor 18 through the rotating shaft at the output end. An air inlet slot 13 is opened on the right side of the installation box 5. An exhaust hole 7 is opened on both the front and back of the installation box 5.

[0022] When the device is in use, starting the drive motor 20 drives the movable rod 22 and worm 21 to rotate via the rotating shaft at the output end. Since the worm 21 is meshed with the worm wheel 26, the worm 21 can drive the worm wheel 26 and the connecting pipe 25 to rotate. Then, starting the oil pump 15 draws out the lubricating oil from inside the storage tank 3 through the connecting pipe 4, and then injects it into the outer casing 8 through the connecting pipe. The lubricating oil then re-enters the storage tank 3 through the filter box 23 and the mounting pipe 24, allowing the lubricating oil inside the storage tank 3 to circulate within the storage tank 3 and the outer casing 8. This lubricating oil reduces friction between the worm 21 and the worm wheel 26, and also... The heat generated by friction can be dissipated. Then, the servo motor 18, via its output shaft, drives the rotating fan blade 19 to rotate. The air generated by the rotating fan blade 19 blows towards the connecting pipe 4, cooling the lubricating oil inside and ensuring good heat dissipation. Compared to traditional air cooling, this device combines oil cooling and air cooling, further improving the heat dissipation efficiency of the worm gear reducer. The air inlet slot 13 facilitates air entry into the mounting box 5, while the exhaust port 7 facilitates air exhaust from the mounting box 5. The fixed handle 2 allows the user to easily grip the handle. Handle 2 is used to move the device to a suitable installation location for installation. The protective cover 6 makes the surface of the fixed handle 2 softer, making it more comfortable to grip. The upper oil seal screw 16 and lower oil seal screw 17 allow for easy replacement of the lubricating oil inside the storage box 3 by unscrewing them, improving the device's practicality. The hollow interior of the mounting bracket 1 facilitates the installation of the rubber block 9, which absorbs the impact force generated by device vibration, improving the device's shock absorption effect and enabling more stable operation. As for U... The design of the template 10 and mounting holes 12 facilitates the installation of the device in a suitable position. The multiple mounting holes 12 further ensure the device's secure installation. The design of the connecting block 11 and connecting holes 14, with the connecting block 11 having a square cross-section, facilitates the connection of the connecting rod 25 to the external movable shaft. The filter box 23 and filter screen facilitate the filtration of lubricating oil entering the storage box 3, preventing debris from wear on the worm gear 21 and worm wheel 26 from entering the storage box 3 and thus preventing damage to the oil pump 15. All electrical equipment in this device is powered by an external power source.

[0023] In one aspect of this embodiment, the interior of the mounting bracket 1 is hollow, which facilitates the installation of the rubber block 9. The rubber block 9 can absorb the impact force generated by the vibration of the device, which helps to improve the shock absorption effect of the device and make the device operate more stably. The U-shaped plate 10 and the mounting holes 12 make it easy to install the device in a suitable position. Since there are multiple mounting holes 12, the installation of the device can be further guaranteed to be firm.

[0024] In one aspect of this embodiment, the fixed handle 2 allows the user to easily move the device to a suitable installation position by holding the fixed handle 2. The protective cover 6 makes the surface of the fixed handle 2 softer, making the fixed handle 2 more comfortable to hold. The upper oil seal screw 16 and the lower oil seal screw 17 allow for easy replacement of the lubricating oil inside the storage box 3 by unscrewing the upper oil seal screw 16 and the lower oil seal screw 17, which helps to improve the practicality of the device.

[0025] In one aspect of this embodiment, the connection block 11 and the connection hole 14 are provided, and since the cross-section of the connection block 11 is square, it is convenient for the connection rod 25 to be connected to the external movable shaft. The filter box 23 and the filter screen are provided to facilitate the filtration of the lubricating oil entering the storage box 3, and to prevent the debris generated by the wear of the worm gear 21 and the worm wheel 26 from entering the storage box 3, thereby preventing damage to the oil pump 15.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
