Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 6 As shown, the utility model discloses a reducer case with good cooling performance, including a case 1, an oil pump 2 and a plate cooler 3 are fixedly arranged on the outer side of the case 1, an oil pipeline 41 is arranged between the oil pump 2 and the plate cooler 3, the oil pump 2 is also provided with an oil inlet pipeline 42, and the plate cooler 3 is provided with an oil outlet pipeline 43, and the oil outlet pipeline 43 is connected to a distribution pipeline mechanism that leads to multiple positions inside the case 1. The specific position of the distribution pipeline mechanism leading to the inside of the case 1 is set according to the position of the rotating shaft gear in the case 1, so as to cover as much of the rotating shaft and gear as possible for lubrication. In addition, in the utility model, an input shaft mounting seat 7 is detachably connected to the case 1 through a flange structure, and a water circulation internal cooling mechanism is provided on the input shaft mounting seat 7.

[0027] The utility model inputs lubricating oil through the oil pump 2, the lubricating oil is cooled through the plate cooler 3, and then enters the housing 1 through the distribution pipeline mechanism. In addition, the utility model is also provided with a water circulation internal cooling mechanism on the input shaft mounting seat 7. The utility model combines the two cooling methods of oil cooling and water cooling, effectively reduces the temperature of the entire reducer housing 1, and improves the operating stability and reliability of the reducer.

[0028] Specifically, the water circulation internal cooling mechanism includes a water cooling cavity 71 opened in the input shaft mounting seat 7, and a water inlet joint 72 and a water outlet joint 73 leading to the water cooling cavity 71 are provided on the input shaft mounting seat 7. The water inlet joint 72 and the water outlet joint 73 are connected with an external water source to form a water circulation. The cooling water enters the water cooling cavity 71 to dissipate the heat of the input shaft mounting seat 7. Because the input shaft mounting seat 7 is for the input shaft to be installed, the input shaft speed of the reducer is generally faster, so the heat generated is also relatively large. Specially water cooling the input shaft mounting seat 7 is beneficial to improving the service life of the internal structure of the input shaft mounting seat 7.

[0029] Furthermore, the input shaft mounting seat 7 is provided with heat dissipation ribs 74 in a spiral shape in the water cooling cavity 71, and the water inlet joint 72 and the water outlet joint 73 are respectively located on both sides of the water cooling cavity 71, and the outer end of the heat dissipation rib 74 also penetrates through the input shaft mounting seat 7. Further, the input shaft mounting seat 7 has an input shaft mounting hole 75, and the input shaft mounting seat 7 has a heat dissipation groove 76 at the middle position of the inner side wall of the input shaft mounting hole 75, and the two sides of the input shaft mounting hole 75 are used to install the input shaft bearing 81, and the input shaft bearing 81 is used for the input shaft to be installed in the input shaft mounting hole 75, wherein the inner end of the heat dissipation rib 74 located at the heat dissipation groove 76 penetrates into the heat dissipation groove 76, and the provision of the heat dissipation rib 74 is conducive to better taking away the heat of the input shaft mounting seat 7 during the circulation of cooling water, and cooling it efficiently.

[0030] In the present invention, the distribution pipeline mechanism includes a multi-pass water seat 51, the oil outlet pipeline 43 is connected to the multi-pass water seat 51, and at least two oil inlet pipes 52 are connected to the multi-pass water seat 51. Each oil inlet pipe 52 is connected to a different position in the housing 1. The position where the oil inlet pipe 52 is connected to the housing 1 is preferably the rotation position of the bearing and the rotating shaft in the reduction housing or the meshing position of the gears. In addition, a secondary oil inlet pipe 53 is connected to the multi-pass water seat 51, and an oil inlet 77 connected to the input shaft mounting hole 75 is opened on the input shaft mounting seat 7. The auxiliary oil inlet pipe 53 is connected to the oil inlet port 77, which is used to lubricate the input shaft and the input shaft bearing inside the input shaft mounting seat 7. A flow channel is provided inside the multi-way water seat 51 to connect the oil outlet pipeline 43 with each oil inlet pipe 52 and the auxiliary oil inlet pipe 53, so that the lubricating oil can flow into the housing 1 and the input shaft mounting seat 7, and the lubricating oil flowing into the input shaft mounting seat 7 will eventually flow into the housing 1. The input shaft mounting seat 7 is provided with an oil seal 85 at the end of the input shaft mounting hole 75 away from the housing 1 to prevent the lubricating oil from flowing out.

[0031] An oil drain valve 82 is provided on one side of the housing 1, which is opened when the lubricating oil in the housing needs to be discharged. In addition, an oil cup 83 is provided on the top of the housing 1, and an air filter 84 is provided on the oil cup 83.
