The Analysis of Insoluble Substance of in-Service Wind Turbine Gear Oil

Abstract

Due to the influence of environment, temperature and rapid changes in load, wind turbine gear oil is usually prone to product insoluble substances, which affects the lubrication performance of the lubricant and shortens the service life of the equipment. In this paper, the components of insoluble substance in gear oils were not only studied by means of infrared spectroscopy, inductively coupled plasma emission spectroscopy (ICP) and other physical and chemical analysis, but also the reasons for the presence of insoluble substance were analyzed. Methods for preventing the formation of insoluble substance and removing them were proposed to help lubricants maintain the lubrication performance, and thus provide technical support for the efficient and stable operation of lubrication system.
