Abstract

Firstly, this paper analyzes the limitations of rolling bearings application in wind turbine transmission systems, and the feasibility of journal bearings "replace rolling with sliding" is explored. Then, from the four key links of wind turbine journal bearing structure design, bearing material, performance analysis and optimization, experimental testing and application, the existing technical means and difficulties faced by journal bearing application in wind turbine are reviewed. Finally, the development trend of material modification, integrated design, and life extension technology of wind turbine journal bearings are prospected.
