Research Status and Development Trends in the Hybrid Lubrication Performance of Wind Turbine Sliding Bearings in Wind Turbines

With the policy drive for the development of clean energy in China, wind turbine (WT) has experienced rapid growth due to its unique advantages. Bearings play a significant role in transmission and supporting, with high failure frequency. Compared with rolling bearings, Sliding bearings have advantages such as high reliability and high tolerance to impurities. Accordingly, sliding bearings are increasingly popular in WT. While wear is the fundamental type of damage leading to failure in sliding bearings. Therefore, studying mixed lubrication is of great significance for the development of the entire wind energy industry. This paper summarizes the research status of mixed lubrication in sliding bearings, and analyzes the main challenges and future development of sliding bearings in wind turbines.
