Abstract

The friction and wear volume loss is the main cause for a failure & energy losses in heavy-duty gearboxes and it can be controlled by using a modified lubricant mixed with nano additives. This study investigates the wear and friction behaviour of gear EP oil blended with composite nano additives (Al2O3/SiO2/ZrO2) in combination with Zinc dialkyl dithiophosphate. All trials were conducted under various concentrations of composite nanoparticles, at loads of 60-100 N and sliding velocities of 0.65-1.5 m/s. The experimental study on antiwear and anti-friction properties for the oil was conducted on a pin-on-disc apparatus. The design of experiment was developed using response surface approach to investigate optimum friction coefficient and wear volume loss in lubricant. It is found that blending of nano composite add-ons blended with Zinc dialkyl dithiophosphate in gear EP lubricant significantly diminishes a wear volume loss, friction coefficient by 15.62 % and 20.6 % respectively as compared to a base lubricant. The findings of this investigation and the obtained correlations were converted in to customized visual basis based soft tool as a predictor for future aspects.

混合了 Al2O3/SiO2/ZrO2 复合添加剂的齿轮极压润滑油的实验研究--设计一种预测系统

摩擦和磨损体积损失是造成重型齿轮箱故障和能量损失的主要原因，可通过使用混合了纳米添加剂的改性润滑油来控制。本研究调查了混合了复合纳米添加剂（Al2O3/SiO2/ZrO2）和二烷基二硫代磷酸锌的齿轮极压油的磨损和摩擦性能。所有试验都是在不同浓度的复合纳米颗粒、60-100 牛顿的载荷和 0.65-1.5 米/秒的滑动速度下进行的。对油的抗磨损和抗摩擦特性的实验研究是在针盘装置上进行的。实验设计采用响应面法来研究润滑油的最佳摩擦系数和磨损体积损失。结果发现，与基础润滑油相比，在齿轮极压润滑油中掺入纳米复合添加剂和二烷基二硫代磷酸锌可显著降低磨损体积损失和摩擦系数，分别降低 15.62% 和 20.6%。这项调查的结果和获得的相关性被转化为基于视觉的定制软工具，作为未来方面的预测工具。
