摘　　要：为满足现代直升机传动系统的使用要求,参照美军DOD-PRF-85734A规范,以多元醇酯作为基础油,合成低聚抗氧剂和极压抗磨剂,优化配方,研制了传动系统润滑油。研制油黏度、酸值、橡胶相容性、热氧化安定性等性能与国外参考油相当,在极压抗磨性能方面优于国外参考油。研制油通过台架试验和实机试飞试用试验,可用于先进型号的直升机。To meet the requirements of the advanced helicopter transmission system,a type of helicopter transmission lubricating oil was developed with reference to specification issued by the U.S.Department of Defense DOD-PRF-85734A,using polyol ester as a base oil,the self-synthesized oligomer antioxidant and extreme pressure antiwear agent.The properties of the synthesized lubricating oil are similar with a foreign reference sample in viscosity,acid number,rubber compatibility and thermal oxidative stability,but better in extreme pressure antiwear property.The bench test and flight test proved that the developed lubricating oil can be used in advanced types of helicopters.
