[Abstract]:With the rapid development of automobile industry, the global resource crisis is becoming more and more obvious. Whether automobile, locomotive, all machinery, lubricating effectiveness determines the number of years of service and dynamic efficiency of the machinery, lubricating oil or grease quality, selection has become the most important subject. In this study, MS-800 four-ball tester was used in the study of p-thio-borate, nitroborate and calcium hexadecyl borate in a new pentyl polyol ester (NPE-3). Tribological study on five boron additives of octadecyl calcium octadecyl thioboric acid calcium octadecoxy azoboric acid, in the presence of neopentyl polyol ester (NPE-3) and isooctyl adipate (1: 1) for the treatment of poly (pentafisulfide), dialkyldithiocarbamate, dialkyl dithiocarbamate, Tribological study of lard cd-1 dithiophosphate was carried out. Five series of boron additives, such as sulfide-containing borate, nitroborate, calcium hexadecyl borate, octadecoxy nanometer calcium thioborate and octadecoxy azoboric acid calcium, were prepared by uniform design method. Phosphorus star, isobutene sulphide and triazole aliphatic salt were designed at the levels of 3 factors 7 and 5 factors 9 in the new pentyl polyol ester NPE-3, and the experimental results were optimized by artificial neural network method. The experimental verification and error analysis are also carried out to verify the accuracy of the preliminary test and to select a more optimized additive content ratio. The friction surface state and mechanism are analyzed by means of electron microscopy and energy dispersive spectroscopy. The tribological rules of boron series additives in neopentyl polyol ester (NPE-3) and the synergistic effect of boron series additives with traditional sulfur and phosphorus series additives in neopentyl polyol ester (NPE-3) were studied, and the lubrication mechanism was analyzed. The effect of pressure on the diameter of wear spot under different loads was studied. The effect of borate additive containing nitrogen on the composition and chemical state of friction surface film of steel ball was analyzed by scanning electron microscope (SEM) in order to reveal the mechanism of interaction between additives. The neural network model of tribological properties of various additives in neopentyl polyol ester (NPE-3) was established by using BP neural network theory. In the face of the requirement of environmental protection and the development trend of automobile gear lubrication, it is imperative to develop and develop environment-friendly automobile gear lubricating oil. It is of great significance to carry out the lubricating performance of environment-friendly automobile gear lubricating oil.
