Description

一种汽车润滑油 一种汽车润滑油
技术领域
本发明涉及汽车零件领域，特别涉及一种汽车润滑油。
背景技术
汽车齿轮油用于机械式变速器、驱动桥和转向器的齿轮、轴承等零件的润滑，起到润滑、冷却、防锈和缓冲的作用。由于汽车齿轮工作条件复杂，接触压力大，圆周速度快，滑动速度高，油温高，故对齿轮油的要求较高。双曲线齿轮传动的工作条件更苛刻，对汽车齿轮油使用性能要求更高，如果没有合适的齿轮油，就不能保证齿轮的正常润滑，容易导致齿轮的早期磨损和擦伤，甚至会造成大的车辆和人身事故。因此，要保持汽车发动机的动力正常的传递，汽车齿轮油的质量就非常重要。
发明内容
本发明要解决的技术问题是提供一种减小汽车齿轮的磨损量，达到润滑的最大无卡咬负荷、减少烧结负荷和综合磨损，延长发动机寿命的汽车润滑油。
为解决上述技术问题，本发明的技术方案为：一种汽车润滑油，其创新点在于：按重量分数配比由以下组分制成：
新戊基多元醇酯87-98份；
BHT抗氧剂1-2.2份；
极压剂 4-6份；
亚磷酸二正丁酯1-1.7份；
硫磷丁辛醇锌盐3-5份；
猪油4-6份；
石油磺酸钠2.1-2.8份；
氯化石蜡4-7份；
磷之星4-6份；
甲基硅油1-3份；
烷基萘1.4-3.2份。
进一步的，所述极压剂为聚五硫化物。
本发明的优点在于：本发明具有极好的极压抗磨性能，承载能力较高许多配方可达2832N以上，其中最高达5653.975N，可配置重负荷车辆齿轮油，也可用于重负荷和中负荷工业齿轮油。
本发明配方科学合理，使得齿轮钢球的润滑不发生卡咬最高负荷，在该负荷下摩擦表面间能保持完整的油膜；使得齿轮钢球发生烧结的最低负荷，达到润滑的极限工作能力；使得齿轮钢球综合磨损值的若干次校正负荷数学平均值，达到润滑从低负荷至烧结负荷整个过程的平均抗磨性能，本发明汽车齿轮油的工作温度范围也比较宽，最大限度满足汽车齿轮的润滑，并延长其使用寿命。
