Wind Turbine Bearings

     Green, clean energy needs of advanced product support. UBC followed the trend of development of wind power wind turbine bearings is committed to R & D and manufacturing, have been formed from 600kW ~ 2.0MW units with the yaw bearings, blade (pitch) bearing, spindle bearing, gearbox bearing the R & D manufacturing capacity, can provide customers with a series of wind turbine bearings. Key supporting wind turbine bearings, including: Yaw Bearing System Bearing pitch system Spindle bearings Bearing other systems (generator bearings and gears bearings) Yaw Bearing System: wind power installed base assembly cabin yaw agencies for accurate and timely adjustment of the fan angle of the wind, and lightning conduction to the ground, carrying the full weight of main drive fan (axial radial load load and overturning moment). Requires good sealing performance, high reliability, stable operation and good flexibility and surface corrosion life of more than 20 years and so on. This kind of bearings generally use large four point contact or cross cylindrical roller wheel bearings. Bearing pitch system: changes in the slurry system blade assembly, the leaf used to adjust the wind direction, mainly bear radial load, axial load and overturning moment. Require the bearing has good sealing performance, high reliability, surface corrosion, and operation of flexible, life is more than 20 years and so on. Class bearings generally used four large webbed contact or double wheel bearings volleyball. Spindle bearings: Located fan spindle, high workload, and requires the ability to compensate for the deformation of the spindle. Therefore, the bearings should be aligning with a good performance, high load capacity and longer service life. Commonly used by optimizing the design of spherical roller bearings.
