Optimised bearings improve reliability of wind turbines: Liu Su examines the general failure modes of wind turbine gearbox bearings, and looks at the solutions to the problem

摘要

As the transmission part that connects the rotor and generator, the wind turbine gearbox transforms the low-speed input of the rotor into an output that the medium- or high-speed generator needs. It is one of the major components of the wind turbine. Because of the complexity of working conditions and the high reliability required by the wind turbine gearbox, its design, application (particularly the bearing selection), installation and operation become even more important.
