  • Fatigue life analysis of slewing bearings in wind

    2018-6-1 · Slewing bearings are important components of wind turbines and composed of a yaw bearing and a pitch bearing. They have driving teeth in the inner or outer ring that drive the pinion gear and transmit torque to achieve the wind turbine yaw and pitch movement, as shown in Fig. 1.The common yaw bearing is a four-point contact ball slewing bearing with a zero cross-section gap or microsection …
