Development Status of Design and Performance Testing Technology forWind Turbine Sliding BearingsCHEN Qi1,ZHANG Kai1,ZHU Jie1,2,ZHANG Yabin1,2,FENG Kai1 (1.Key Laboratory of High-end Intelligent Equipment Key Components in Hunan Province,Hunan University,Changsha 410006,China;2.Hunan SUND Technological Corporation,Xiangtan 411101,China) Abstract: Wind power is an important development direction of clean energy in China,and the large-scale development of wind turbines is an important measure to reduce the cost of wind power generation.With the development of wind turbines towards large-scale direction,the fault rate and processing cost of traditional rolling bearings for wind turbines increase significantly with the increase of size of the bearings,becoming a problem of ' stuck neck ' that restricts the large-scale development of wind turbines.The sliding bearings have the characteristics of high stability,good tolerance to material defects and external impurities,low processing cost,which are expected to overcome the shortcomings of traditional rolling bearings for wind turbines,and has become the development trend of large-scale wind turbine bearings.Based on current development status of design and performance testing technology for wind turbine sliding bearings during the process of 'sliding instead of rolling',the technical difficulties faced by main shaft bearings and gearbox bearings for wind turbines are introduced,such as low speed,heavy load,complex external interference,frequent start and stop.A detailed analysis is conducted on common structural forms,lubrication performance analysis and structural optimization design methods of wind turbine sliding bearings,as well as research status of evaluating the performance and lubrication status of the bearings through methods such as detecting and monitoring the film thickness,temperature,oil wear particles,wear and vibration.Finally,the research directions on the bearings are prospected,providing reference for development of the bearings.
