Single or double- row four-point contact ball bearings with cages are used, with internal orBearing and gearbox failures Challenge to wind turbinesA 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 what Forged steel rotor wind turbine main shaft pass certified by ABSCONNECTION METHODS IN WIND TURBINE ROTOR o Certification. In the past two decades, a continuous trend for upscaling wind turbines is seen, which has for a part been enabled by more material-efficient rotor blade designs.
