The cooler body 3 is detachably mounted on the top of the first mounting bracket 1. A filter box 5 is provided on the second mounting bracket 2. One end of the first hot oil outlet pipe 6 of the reducer is connected to the filter box 5. One side of the filter box 5 is connected to the forced lubrication pump 4 through a connecting pipe 7. A second hot oil outlet pipe 8 is provided at the output end of the forced lubrication pump 4. A cooler oil inlet 9, a cooler oil outlet 10 and a cooling water pipe interface 11 are provided at the top of the cooler body 3. One end of the second hot oil outlet pipe 8 is connected to the cooler oil inlet 9. A cooling return oil pipe 12 is provided at the cooler oil outlet 10. A cooling water pipe body 13 is provided at the cooling water pipe interface 11. The cooling return oil pipe 12 of the present utility model is connected to the reduction gearbox of the reducer.
[0020] When the cooler added to the reducer of the present utility model is in operation, the high-temperature oil in the reduction gearbox of the reducer comes out through the first hot oil outlet pipe 6 and then enters the filter box 5 to be filtered. The filtered high-temperature oil enters the forced lubrication pump 4 along the connecting pipe 7. Then the forced lubrication pump 4 pumps the high-temperature oil into the second hot oil outlet pipe 8, and then enters the cooler oil inlet 9 along the second hot oil outlet pipe 8 and finally enters the cooler body 3 to be cooled. The cooled oil enters the reduction gearbox of the reducer again through the cooling return oil pipe 12.
[0021] A reinforcing bracket 14 is provided on the front side of the cooler body 3, and the reinforcing bracket 14 is detachably installed on the back plate of the cooler body 3 through reinforcing bolts. The installation stability of the main part of the cooler body 3 can be improved through the reinforcing bracket 14.
[0022] The filter box 5 includes a box body 501, a first filter rack 502, a second filter rack 503 and a switching control mechanism. The first filter rack 502 and the second filter rack 503 are movably arranged inside the box body 501. A switching control mechanism is arranged inside the filter box 5, and both the first filter rack 502 and the second filter rack 503 are connected to the switching control mechanism. A first slide bar 504 and a second slide bar 505 are arranged inside the box body 501, and there are four groups of both the first slide bar 504 and the second slide bar 505. The first filter rack 502 is slidably connected to the four groups of the first slide bars 504, and the second filter rack 503 is slidably connected to the four groups of the second slide bars 505. The first filter rack 502 and the second filter rack 503 have the same structure, and both include a rack body 15, a first filter plate 16 and a second filter plate 17. The first filter plate 16 and the second filter plate 17 are arranged inside the rack body 15, and a pull rod 18 is arranged at the top of the rack body 15. The switching control mechanism includes a driving gear 19, a first rack 20, a second rack 21, a driving shaft 22, a worm gear 23 and a worm 24. A first rack 20 is arranged on the outer wall of the rack body 15 of the first filter rack 502, and a second rack 21 is arranged on the outer wall of the rack body 15 of the second filter rack 503. A driving shaft 22 is rotatably arranged inside the box body 501, and a driving gear 19 and a worm gear 23 are arranged on the driving shaft 22. The driving gear 19 meshes with the first rack 20 and the second rack 21. A worm 24 is rotatably arranged on the box body 501, and the worm 24 meshes with the worm gear 23. When the filter box 5 of the present utility model operates for filtration, the high-temperature oil entering is filtered through the first filter rack 502 or the second filter rack 503. The first filter rack 502 and the second filter rack 503 can alternately perform filtration operations, and the process is switched and controlled through the switching control mechanism. When the first filter rack 502 is used for filtration, the first filter rack 502 is located below one side inside the box body 501, and the second filter rack 503 is located above the other side inside the box body 501. The high-temperature oil passes through the first filter plate 16 and the second filter plate 17 of the first filter rack 502 for filtration and then enters the connecting pipe 7. When the filtration capacity of the first filter plate 16 and the second filter plate 17 of the first filter rack 502 decreases, the second filter rack 503 can be switched to perform the filtration operation. Specifically, by rotating the worm 24 to drive the driving shaft 22 to rotate, the driving gear 19 installed on the driving shaft 22 drives the rack bodies 15 (both on the first filter rack 502 and the second filter rack 503) installed with the first rack 20 and the second rack 21 to move upward, realizing the switching and use of the first filter rack 502 and the second filter rack 503.

The utility model realizes filtering of the high-temperature oil coming out of the reduction gearbox of the reducer by connecting a filter box 5 to one end of the first hot oil outlet pipe 6 of the reducer. After filtering, the oil enters the cooler body 3 for cooling. This process can not only avoid damage to the cooler body 3 caused by high-temperature oil containing impurities, but also reduce the damage to the reduction gears in the reduction gearbox of the reducer by the purified oil.
