Bearings belong to the essential components in the wind turbine. Wind power bearings range from bearings used in blades, spindles and yaw, to high-speed bearings used in gearboxes and generators. In general, wind power bearings include yaw bearings, pitch bearings, spindle bearings, gearbox bearings and generator bearings. Among them, the yaw bearing generally use single-row four-point contact ball turntable bearings, double row four-point contact ball turntable bearings and cross cylindrical roller turntable bearings. Pitch bearings generally use double row four-point contact ball turntable bearings, single-row four-point contact ball turntable bearings, cross cylindrical roller turntable bearings, three-row roller turntable bearings. Spindle bearings are generally used spherical roller bearings, cylindrical roller bearings, double row tapered roller bearings, single row tapered roller bearings. Gearbox bearings are generally made of cylindrical roller bearings, single row tapered roller bearings, spherical roller bearings, single row deep groove ball bearings and double row tapered roller bearings. Generator bearings generally use cylindrical roller bearings, deep groove ball bearings and so on. Because of harsh conditions of wind power equipment and requirements of long life and high reliability, making the wind power bearings have a higher technical complexity, is recognized as one of the most difficult part (including bearing and control system).
