Detailed Implementation

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 2 , Figure 3 , Figure 4 as well as Figure 5 This embodiment proposes a high-precision gearbox, including a housing 1. An oil cooling box 2 for oil cooling is fixedly installed on the inner wall of the housing 1. An oil cooling pipe 21 for circulation is connected to the outer side of the oil cooling box 2. The inner wall of the bottom end of the oil cooling pipe 21 is fixedly connected to the inner wall of the housing 1. An oil cooling assembly 3 for driving oil circulation is provided on the inner wall of the oil cooling pipe 21. An inner liner 22 for lubrication drive is fixedly installed on the inner wall of the oil cooling pipe 21. A drive rod 4 and two driven rods 5 for driving are rotatably connected to the inner wall of the inner liner 22. One end of the drive rod 4 and the driven rods 5 are respectively fixedly installed with a drive rod 4 for driving and two driven rods 5 for driving. The drive mechanism consists of a main bevel gear 41 and a secondary bevel gear 51, which mesh with each other. The top of the oil cooling box 2 is connected to a lubrication tank 6 for storing lubricating oil. The outer side of the drive rod 4 is rotatably connected to the inner walls of the lubrication tank 6 and the oil cooling box 2, respectively. The outer side of the driven rod 5 is rotatably connected to the inner walls of the oil cooling box 2 and the box body 1, respectively. Two water-cooled boxes 7 are fixedly installed on the outer side of the oil cooling box 2. Two connecting pipes 71 and 72 are fixedly installed at both ends of each water-cooled box 7 for communication. The outer side of the water-cooled box 7 is fixedly connected to the inner wall of the box body 1. The inner wall of the water-cooled box 7 is equipped with a water-cooling component 8 for water circulation, and the inner wall of the box body 1 is equipped with an air-cooling component 9 for air-cooling circulation. When the drive rod 4 drives the main bevel gear 41 to rotate inside the inner liner 22, it can drive the driven rod 5 to rotate inside the inner liner 22 through the action of the secondary bevel gear 51. At the same time, the lubrication box 6 is connected to the inner liner 22, allowing lubricating oil to flow into the inner liner 22 and play a lubricating role during the meshing and driving process of the main bevel gear 41 and the secondary bevel gear 51. The oil-cooling box 2 outside the inner liner 22 can be used to cool the inner liner 22 and the main bevel gear 41 and the secondary bevel gear 51 inside it. The secondary bevel gear 51 performs oil cooling, and at the same time, the oil in the oil cooling box 2 and the oil cooling pipe 21 can be circulated through the oil cooling component 3. Meanwhile, the water cooling component 8 circulates the water in the water cooling box 7, the first connecting pipe 71 and the second connecting pipe 72, thereby performing water cooling treatment on the oil cooling box 2. Furthermore, through the action of the air cooling component 9 inside the box 1, the oil cooling box 2 and the water cooling box 7 inside the box 1 are further continuously cooled, thereby effectively preventing the wear of gears caused by heat accumulation during gear meshing drive, which leads to the problem of reduced accuracy caused by gear wear inside the gearbox.

[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5This embodiment proposes a high-precision gearbox. The oil cooling assembly 3 includes a connecting rod 31, a transition rod 32, and a first circulation rod 33 rotatably connected to the inner wall of the oil cooling box 2. The top end of the connecting rod 31 is fixedly connected to the bottom end of the drive rod 4. The oil cooling assembly 3 also includes a transition bevel gear 34 fixedly installed at the bottom end of the connecting rod 31 and the other end of the transition rod 32. The oil cooling assembly 3 also includes a first gear 35 and a second gear 36 fixedly installed at one end of the transition rod 32 and the first circulation rod 33, respectively. The first gear 35 meshes with the second gear 36. When it is necessary to circulate the cooling oil inside the oil cooling box 2 and the oil cooling pipe 21, the drive rod 4 can drive the connecting rod 31 to rotate, and the transition bevel gear can circulate the oil. The wheel 34 drives the transition rod 32 to rotate, and simultaneously, through the action of the first gear 35 and the second gear 36, drives the first circulation rod 33 to rotate rapidly inside the oil cooling pipe 21. This accelerates the circulation of cooling oil inside the oil cooling pipe 21 and the oil cooling box 2, achieving a preliminary cooling effect. The water cooling assembly 8 includes a second circulation rod 81 rotatably connected to the inner wall of the water cooling box 7. Two first pulleys 82 are fixedly installed on the outer sides of both ends of the second circulation rod 81 and the first circulation rod 33. A first transmission belt 83 is sleeved on the outer side of the two first pulleys 82. The water circulation inside the water cooling box 7, the first connecting pipe 71, and the second connecting pipe 72 can be achieved through the action of the first pulleys 82 and the first transmission belt 83, thus enabling the first... The circulation rod 33 can drive the second circulation rod 81 to circulate water inside the water-cooled box 7, thereby further cooling the water. The air-cooled assembly 9 includes two guide rods 91 rotatably connected between the second connecting pipe 72. A second pulley 92 is fixedly installed at both ends of the two guide rods 91 and the first circulation rod 33. A second transmission belt 93 is sleeved on the outer side of the second pulley 92. The air-cooled assembly 9 also includes a first filter screen 94 and a second filter screen 95 fixedly installed on the inner walls of both ends of the box 1. A rotating rod 96 is rotatably connected to the inner wall of the first filter screen 94. A scraper 97 is fixedly installed at one end of the rotating rod 96, and the other end of the rotating rod 96 is rotatably connected to the outer side of the top end of the oil cooling pipe 21. The air-cooled assembly 9 also includes a transition rod. A third pulley 98 is fixedly installed at one end of the first circulation rod 32 and the other end of the rotating rod 96. A third transmission belt 99 is sleeved on the outer side of the third pulley 98. When the first circulation rod 33 rotates, the guide rod 91 can rotate inside the housing 1 through the action of the second pulley 92 and the second transmission belt 93, so as to continuously guide the air inside the housing 1. The air entering the housing 1 can be filtered through the first filter screen 94 and the second filter screen 95. The dust accumulated on the first filter screen 94 can be cleaned by the scraper rod 97 through the action of the third pulley 98 and the third transmission belt 99, so that the transition rod 32 can drive the rotating rod 96 and the scraper rod 97 to rotate.

[0026] In this embodiment, during use, the oil inside the oil cooling box 2 and the first circulation rod 33 rotates inside the oil cooling pipe 21, which circulates the oil and provides initial cooling for the main bevel gear 41 and the secondary bevel gear 51. Next, the water inside the water cooling box 7 rotates through the second circulation rod 81, which circulates the water and provides water cooling for the oil cooling box 2. Furthermore, the rotation of the guide rod 91 inside the box 1 allows the air inside the box 1 to be filtered and flow through the first filter screen 94 and the second filter screen 95, further and continuously cooling the oil cooling box 2 and the water cooling box 7 inside the box 1. This effectively prevents gear wear caused by heat accumulation during gear meshing, thus avoiding the problem of decreased precision due to gear wear inside the gearbox.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
