Description

一种传动系统齿轮油组合物及其应用
技术领域
本发明属于润滑剂领域,具体涉及一种传动系统齿轮油组合物及其应用,尤其涉及一种减摩效果好的传动系统齿轮油组合物及其应用。
背景技术
近年来严格的燃烧效率和排放的标准促进了节能、高效车辆的快速发展。纯电动汽车和油电混合动力汽车作为新能源汽车的代表是实现节能与环保的重要突破口。从节能和排放的要求看,纯电动车应为最终发展的方向,油电混合动力车是应对目前纯电动汽车发展瓶颈(电池技术没有大的突破,续航里程较短,充电时间长等)的一种过渡方式。
纯电动汽车传动系统多采用电机+单级/两级减速器的方式,仍然需要润滑油进行润滑。电机+单级/两级减速器传动形式结构较为简单,没有离合器,没有同步器,只有固定速比的齿轮。由于减速器和电机耦合在一起,对油品的散热性能、绝缘性能、抗铜腐蚀、剪切安定性等提出了较高的要求,普通的手动变速箱油和自动变速器油不能完全满足其润滑要求。
此外,随着高速铁路动车组运行速度越来越快,下一代时速400公里及以上的高铁要求满足低温升(≤90℃)、长检修周期(≥330万公里)和高传递效率(>97%)等关键指标。目前时速350公里使用的动车组齿轮箱油存在温升大的问题,随着速度的提升,温升问题将更加明显。为了降低摩擦温升需要在保证油膜承载能力的前提下尽量降低润滑油粘度。
CN109321340A公开了一种抗氧化性强的汽车齿轮润滑油,配方中的原料按重量百分比组成分别是:纯矿物油5-15%、聚醚合成油1-5%、烷基苯油1-10%、可生物降解脂类油5-15%、生物基基础油3-9%、合成润滑油2-3%、油酰胺1-5%、极压抗磨剂11-19%、抗氧防腐剂5-7%、金属钝化剂3-5%、防锈剂3-5%、抗泡沫剂1-5%、油性剂5-10%、粘度指数改进剂1-1.5%,此时汽车齿轮油具有较强的极压抗磨性,且拥有较强的抗氧化性能。
CN104371811A公开了一种抗氧化性能好的齿轮专用润滑油,包括如下质量份数的组份:650SN基础油50-70份,250BS基础油5-15份,150BS基础油15-25份,聚乙烯醚3-6份,烷基苯磺酸钙4-8份,乙丙共聚物3-7份,亚硫酸钠1-4份,十二烷基苯磺酸钠4-6份,苯甲酸甲酯2-6份,复合抗氧剂0.7-2.5份,三乙醇胺2-4份,极压抗磨剂0.2-1.5份,金属减活剂1.0-3.5份,清净剂1.0-3.0份,分散剂1.5-3份。该润滑油具有很好的抗磨性,能够承受齿轮高速转动,啮合产生的高温,具有很好的冷却性,且抗极压能力很强,适合于发动机,大型机械。
由于目前对于齿轮润滑油的温升和摩擦的降低存在迫切的需求,因此,如何提供一种减摩效果好,温升低的齿轮润滑油,成为了亟待解决的问题。
