Bearing and gearbox failures: Challenge to wind turbines

A wind turbine creates electricity when wind flows across the turbine blade and spins the rotor. The rotor is connected to a generator directly in a direct drive turbine or through a shaft and a series of gears (i.e., a gearbox) that speed up the rotation and allow for a physically smaller generator (see Figure 1). 15 This translation of aerodynamic force to rotation of a generator is …
