Description

Lubricating oil for ore clamping hub reduction gear Technical Field The invention relates to the technical field of lubricating oil, in particular to lubricating oil for a mineral card hub reduction gear. Background The mining hub reduction gear is used as a core transmission component of mine heavy equipment, and the stable and reliable operation of the mining hub reduction gear directly relates to the production efficiency and the service life of the whole equipment. In actual working conditions, the speed reducer is in extremely severe comprehensive environments such as high load, strong impact, multiple dust, moisture and the like for a long time, and extremely severe performance requirements are set on the adopted lubricating oil. Although the traditional lubricating oil product is widely applied to general industrial gear lubrication, when the special working conditions of mines are met, the performance short plates are increasingly prominent, and the traditional lubricating oil product is mainly characterized by insufficient micro pitting corrosion resistance, limited extreme pressure wear resistance and unsatisfactory chemical stability and oil film strength retention at high temperature. The surface of the gear of the wheel-side speed reducer is easy to generate micro-pitting corrosion and macroscopic abrasion in early stage, and an oil film is easy to crack under high impact load, so that fatigue failure of the gear and damage of a transmission system are accelerated, and the attendance rate and full life cycle operation cost of equipment are seriously affected. With the expansion of mining scale and the iteration of equipment technology, mining equipment is developing towards ultra-high power, ultra-high reliability and ultra-long maintenance period. The extreme heavy load, severe impact, dust, moisture and other environmental factors in actual operation are superimposed, so that the lubrication conditions faced by the transmission parts are more severe. Conventional gear oils have been increasingly inadequate in coping with tooth surface micropitting fatigue damage and wear protection under extreme pressures. Therefore, the industry provides an unprecedented high standard requirement for the comprehensive performance of the lubricating oil of the mining wheel-side speed reducer, especially in the aspects of anti-micro pitting and extreme pressure wear-resistant collaborative protection. The background urgent needs the lubrication technology to break through, and a high-performance special lubricating oil product which can adapt to the extreme working condition of modern mines and has multiple protection functions is developed so as to ensure the long-acting, stable and reliable operation of a mining equipment transmission system in a severe environment.
