车辆齿轮油主要理化性能检测项目除同发动机油基本相同外，还有表观粘度、成沟点、机械杂喷、贮存安定性、热氧化稳定性等。车辆齿轮油的模拟试验主要是齿轮机试验。车辆齿轮油的台架试验主要是ASTM的L-42抗擦伤试验、L-37承载能力试验、L-33锈蚀试验、L-60高温氧化试验等。
车辆齿轮油作为高粘度油品在其配方中涉及较多的重质基础油或增粘剂。
Many heavy base oil and viscosity improvers had been used in automobile gear oil formulation.
本文就粘指剂在车辆齿轮油中的应用进行了考察，结果显示不同粘指剂在应用过程中对油品的低温性能、增粘效果、剪切安定性等形成不同的影响。
In this paper, properties of automobile gear oil used different viscosity improvers, such as viscosity, brookfield viscosity, low temperature fluidity, shear stability, etc. are studied.
