Abstract

Nanostructured boehmite additives in lubricating oils for a D-243 diesel engine and drilling rig gearbox during the breaking-in period are studied. It is demonstrated that the addition of boehmite powder and a surface acting agent to the M-10G₂k engine oil accelerates and improves the quality of running of the diesel engine by up to two times, contributing to rapid achievement of the rated power and fuel consumption. The compound, which contains kaolin, talc, and boehmite powders and a surfactant, reduces the breaking-in period of the drilling rig gearbox by 2.5 times. An analysis of the processes that occur during breaking-in of the engine and gearbox using the developed additives is carried out. The efficiency of breaking-in is supposed to depend not only on the physical and chemical properties of the additive components but also on the ratio of the particle size of the compounding material to the surface roughness of the parts that are subjected to grinding.

使用纳米结构勃姆石粉在拖拉机柴油机和钻机齿轮箱中破碎的经验

摘要

研究了磨合期间 D-243 柴油发动机和钻机变速箱润滑油中的纳米结构勃姆石添加剂。结果表明，在 M-10G ₂中加入勃姆石粉和表面活性剂k 发动机油加速并提高柴油发动机的运行质量高达两倍，有助于快速达到额定功率和油耗。该化合物含有高岭土、滑石、勃姆石粉和表面活性剂，可将钻机齿轮箱的磨合期缩短 2.5 倍。使用开发的添加剂对发动机和变速箱磨合期间发生的过程进行了分析。磨合效率不仅取决于添加剂组分的物理和化学性质，还取决于复合材料的粒径与被研磨部件的表面粗糙度的比率。
