Abstract

The objective of this paper is to study the parameters that affect the remaining useful life of lubricant (RULL). Fourier-transform infrared spectroscopy (FTIR) of gear oil is used to observe the contamination in the oil. Coefficient of friction (COF) has been found out using pin on disc tribometer using gear oil, and simultaneously, wear debris has been collected. Particles distribution and elemental analysis of wear debris were observed by emission scanning electron microscopy (FESEM) Field with energy dispersive x-ray (EDX) respectively. Oxidation, sulfation, soot and water content in lubricant increase with time and decrease the RULL. ANOVA is applied to find out the most influential parameter for wear debris and found a load on gears is the dominating factor for wear. This method is the potential to monitor the root causes of contamination and change in lubricant properties and may help to detect the other early signs of failure.

齿轮材料磨损试验与统计分析

本文的目的是研究影响润滑油剩余使用寿命(RULL)的参数。采用傅立叶变换红外光谱(FTIR)对齿轮油中的污染进行了观察。使用齿轮油，用针盘式摩擦计测定了摩擦系数，并收集了磨损碎片。利用发射扫描电子显微镜(FESEM)和能量色散x射线(EDX)分别观察了磨损屑的颗粒分布和元素分析。润滑油中的氧化、硫化、烟灰和水分含量随时间的增加而增加，RULL降低。运用方差分析方法找出影响磨损碎片的最主要参数，发现齿轮上的载荷是影响磨损的主要因素。这种方法有可能监测污染的根本原因和润滑油性能的变化，并可能有助于检测故障的其他早期迹象。

期刊介绍： Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development. Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on: Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives. State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces. Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles. Gas lubrication. Extreme-conditions lubrication. Green-lubrication technology and lubricants. Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions. Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural. Modelling hydrodynamic and thin film lubrication. All lubrication related aspects of nanotribology. Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption. Bio-lubrication, bio-lubricants and lubricated biological systems. Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
