  • Bearing arrangements for wind turbine main shafts

    Different turbine manufacturers have different design philosophies that influence which bearings they use. One set-up is 'locating and non-locating', which uses two separate bearings on the main shaft. A locating bearing is exposed to both radial and axial loads, while a non-locating bearing accommodates only radial loads.

  • 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 …
