The large gear of the ball mill plays a role in lifting the ball mill during the work of the ball mill. In use, in order to prolong the service life of the ball mill and reduce the use cost, the gear of the ball mill needs to be lubricated and maintained so as to reduce the abrasion between the gear part of the ball mill and other parts and prolong the service life of the gear; the friction between the gears is relieved, and the efficiency is improved; heat is dispersed, so that the damage of a machine caused by overhigh heat is avoided; the large gear is effectively prevented from rusting and corroding, the service life of the large gear is prolonged, and the use cost of the product is further reduced; the noise generated in the work is effectively reduced, the impact effect caused by the vibration between the gears is reduced, and the large gear is protected; dirt between the large gear parts is effectively cleaned, the tooth surfaces of the large gears are kept clean, and abrasion is reduced.
The big gear of the ball mill is an open gear due to the huge size. The early lubricating mode is a mode of manually coating lubricating oil for lubricating, and dry grinding is easily formed due to the factors of uneven coating, unfixed coating time and the like in manual coating, so that a large gear of the ball mill is damaged prematurely. Later, oil injection devices were invented, which use a high-pressure injection mode to atomize lubricating oil through a nozzle and then inject the atomized lubricating oil on the surface of a gear in a timed and quantitative mode. This type of lubrication is becoming the mainstream of ball mill gear lubrication. However, since the spray nozzles for spray lubrication of ball mills usually spray lubricating oil against the pinion, and since the pinion rotates at a high speed, a high-speed air flow layer is present at the edge of the pinion, when the spray nozzles spray the lubricating oil, the lubricating oil needs to pass through the high-speed air flow layer to reach the pinion surface, so that only the tooth root and non-pressure-bearing surface of the pinion are sprayed with a large amount of lubricating oil, and the pressure-bearing surface is sprayed with a small amount of oil. In order to solve the problem, the oil injection quantity and the oil injection pressure need to be increased, and the lubricating oil for the ball mill is non-recycled. Therefore, a large amount of lubricating oil is wasted, the environment is polluted, and the power and the volume of an oil injection system are increased.
