1984年3月调研了有关煤矿输送机、采煤机等设备的润滑情况,发现齿轮副的润滑油,仍有使用机械油,汽缸油和普通工业齿轮油等的现象。这些油品的抗磨性等都较差,已不能满足煤矿机械齿轮精度和速度发展的要求。近年来,煤矿进口的设备增多,但由于对国内外齿轮润滑剂性能了解不够;以及当地石油公司油品种类不全,有什么就用什么的不合理状况等,往往造成代用不当,影 March 1984 investigated the coal mine conveyor, shearer and other equipment lubrication, found that the gear oil, there is still the use of mechanical oil, cylinder oil and general industrial gear oil phenomenon. The wear resistance of these oils are poor, can not meet the requirements of coal mine machinery gear accuracy and speed development. In recent years, the number of imported coal mines has increased, but because of insufficient understanding of the performance of gear lubricants both at home and abroad, as well as the incompleteness of the oil products of local oil companies, what are the unreasonable conditions on their use, they often result in improper substitution
