Moreover, some existing speed reducers lack effective filtration and lubricating oil recycling mechanisms, failing to guarantee the cleanliness and continuous lubrication performance of the lubricating oil. Therefore, a lubricated speed reducer is proposed to address these issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figure 1-3 As shown, this utility model provides a lubricated speed reducer, including a speed reducer body 1 and a filter box 2. The filter box 2 is installed on the lower surface of the speed reducer body 1 and is detachable. A circulation device is provided on one side of the surface of the speed reducer body 1. An oil storage tank 6 is provided at the top inside the speed reducer body 1. A lubrication assembly is connected to the lower end of the oil storage tank 6. The lubrication assembly is located inside the speed reducer body 1. A filter assembly is provided inside the filter box 2.

[0020] Specifically, the circulation device enables the recycling of lubricating oil, avoiding the significant waste of lubricating oil in traditional methods and reducing operating costs. The coarse filter 8 and fine filter 9 effectively filter out impurities in the lubricating oil, ensuring its cleanliness during circulation, further improving lubrication, and extending the service life of the reducer body 1. The oil spray nozzle 12 precisely sprays lubricating oil to the parts that need lubrication, ensuring that all key components receive sufficient and effective lubrication, reducing friction and wear between components, and improving the operating stability and working efficiency of the reducer.

[0021] The circulation device includes an oil suction pipe 4 and a suction pump 5. The suction pump 5 is installed on the surface of one side of the reducer body 1. There are two sets of oil suction pipes 4. One end of each set of oil suction pipes 4 is connected to the inside of the oil storage tank 6 and the filter box 2, respectively. The other end is connected to both ends of the suction pump 5. By starting the suction pump 5, the lubricating oil filtered in the filter box 2 is sucked out through the oil suction pipe 4 and flows into the oil storage tank 6 for circulation.

[0022] The filter assembly includes a filter plate 7, a fine filter screen 8, and a coarse filter screen 9. The filter plate 7 is installed on the inner walls of both sides of the upper end of the filter box 2. The coarse filter screen 9 is located at the lower end of the filter plate 7, and the fine filter screen 8 is located at the lower end of the coarse filter screen 9. Both ends of the fine filter screen 8 and the coarse filter screen 9 are installed on the inner walls of both sides of the filter box 2. The filter plate 7 and the coarse filter screen 9 are used to filter out larger particles of impurities and prevent them from entering the oil storage tank. The fine filter screen 8 is used to perform secondary filtration of the lubricating oil to ensure that the lubricating oil entering the oil delivery pipe has a high degree of cleanliness.

[0023] The lubrication assembly includes a first oil supply pipe 10, a second oil supply pipe 11, and an oil injector 12. The upper end of the first oil supply pipe 10 is connected to the interior of the oil storage tank 6. Two sets of the second oil supply pipe 11 are provided, respectively connected to the two ends of the first oil supply pipe 10. Multiple sets of oil injectors 12 are provided and installed on the surface of the second oil supply pipe 11. When the reducer body 1 is operated, the gears, bearings and other components inside it rotate at high speed, which will cause changes in the air pressure in a local area. The oil injector 12 is located in these pressure change areas. When the internal pressure is lower than the pressure of the lubricating oil in the oil storage tank 6, the lubricating oil will be sprayed out from the oil injector 12 under the action of the pressure difference to lubricate the gear meshing.

[0024] Among them, the upper surface of the reducer body 1 is provided with an oil inlet 3, which is connected to the interior of the oil storage tank 6. Through the oil inlet 3, it is convenient to add lubricating oil to the interior of the oil storage tank 6.

[0025] Working principle: This utility model is a lubricated speed reducer. First, lubricating oil is added to the oil storage tank 6 through the oil inlet 3. When the speed reducer body 1 starts to work, the lubricating oil in the oil storage tank 6 is sprayed into various lubrication parts inside the speed reducer body 1 through the first oil supply pipe 10, the second oil supply pipe 11 and the oil spray nozzle 12 to lubricate the gears, bearings and other components. As the speed reducer body 1 runs, the lubricating oil gradually gathers into the filter box 2 at the bottom of the speed reducer body 1 under the action of gravity. By installing filter plates 7, coarse filter screen 8 and fine filter screen 9 inside the filter box 2, impurities in the lubricating oil can be filtered to prevent them from entering the oil storage tank 6. Then, the suction pump 5 is started to suck out the lubricating oil collected in the filter box 2 and transport it back to the oil storage tank 6 through the suction pipe 4 for recycling.
