直升机主减速器润滑油研究进展

An Overview on the Development of Lubricating Oil for Helicopter’s Main Reducer

通过提高基础油黏度和使用新型添加剂来改进润滑油承载能力,从而提高主减速器的可靠性,是直升机主减速器润滑油的主要发展方向。在综述国内外直升机主减速器润滑油研究进展的基础上,指出我国应发展承载能力更强、符合MIL-PRF-32538规范要求的9厘斯主减速器合成润滑油,同时加强航空润滑油润滑理论研究和使用性能评定设备研究,进一步促进我国航空油料与航空装备的适配性。

The main development direction of helicopter main reducer lubricating oil is to improve it’s load capacity by increasing the viscosity of base oil and using new additives,and increase the reliability of main reducer.On the basis of summarizing the research progress of the helicopter main reducer lubricating oil at home and abroad,this paper points out that our country should develop 9⁃centistokes main reducer synthetic lubricating oil which meets the requirements of MIL⁃PRF⁃32538,and strengthen the research on the lubricating theory and using performance evaluation equipment of aviation lubricating oil so as to promote the adaptability of aviation oil and aviation equipment of our country.
