[0002] Wet ball mill is a commonly used industrial equipment. The cylinder is driven by a reduction motor to rotate. The cylinder drives the ore inside to fall and collide with the steel balls for grinding and crushing. The ore powder after processing to a suitable size can be discharged from the other end of the ball mill. It is often used for grinding ores and other grindable materials.

[0003] The existing wet ball mill is provided with a transmission gear on the outside, and the wet ball mill is driven to rotate by the meshing of the reduction device gear and the outer gear of the wet ball mill. The gear needs to be oiled to reduce the wear during transmission and optimize the meshing transmission of the two gears. The gear oiling method is generally handled by manual operation, the oiling operation is cumbersome, and the oil is unevenly applied on the gear surface, which is very inconvenient.

[0014] The utility model uses a cavity arranged in the gear and an overflow hole for limiting the oil output, in cooperation with a sponge layer. In the process of the gear driving the gear ring to rotate through meshing, the lubricating oil stored in the cavity can slowly seep out of the gear through the overflow hole, continuously soaking a sponge layer of the same shape arranged outside the gear, so that the sponge layer can automatically apply oil to the surface that fits the gear ring during the process of meshing with the gear ring. The process is fully automated, and all tooth blocks of the gear ring can be oiled, with uniform smearing and wide coverage. In addition, the lubricating oil in the gear cavity can be easily added later, with less labor consumption, and is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

During the rotation of the gear 6, the small amount of lubricating oil in the chamber 61 moves with it, and when it moves to the overflow holes 65 at different positions, the sponge layer 7 is gradually soaked. During the subsequent rotation process, the sponge layer 7 is also kept humidified and lubricated in the order of the overflow holes 65, which can avoid waste caused by the overflow holes 65 discharging liquid at the same time, or leakage caused by excessive oil discharge that the sponge layer 7 cannot absorb. The sponge layer 7 is installed in the annular groove 64. The sponge layer 7 has the same shape as the gear 6 and meshes with the gear ring 11. After being soaked with the lubricating oil, the sponge layer 7 can adhere to the surface of the gear ring 11 by fitting with the surface of the gear ring 11 to complete the oiling process.

[0031] When the gear ring 11 needs to be oiled, first assemble the output shaft of the driving device with the coupling 9, then start the driving device to drive the gear 6 to rotate. The gear 6 drives the wet ball mill 1 to rotate by meshing with the gear ring 11. During the rotation of the gear 6, the lubricating oil in the chamber 61 moves with it, and when it moves to the overflow holes 65 at different positions, it flows out through the overflow holes 65 to soak the sponge layer 7. The soaked sponge layer 7 can attach the lubricating oil to the surface of the gear ring 11 while meshing with the gear ring 11, thereby completing the oiling process.
