Green, clean energy need advanced product support. UBC followed the development trend of wind power and committed to the development and manufacture of wind turbines with bearing, has been formed from 600 kw ~ 2. The yaw bearing 0 mw, leaf ( Variable propeller) Bearing, spindle bearing, the gearbox bearing r&d manufacturing capability, can provide customers with wind turbine with a series of bearings. Wind turbine key supporting bearings, including: the yaw system is analyzed. studying bearing bearing spindle bearing system bearing (other Generator bearing and gear bearing) Bearing: yaw system installed on the yaw mechanism of wind generator room base assembly for precise timely adjust the fan's Angle to the wind, and lightning to the ground, carrying the entire weight of the main drive system (fan Radial load axial load and overturning moment) 。 For good sealing performance, high reliability, flexible operation and good stability, surface anti-corrosion life for more than 20 years. The four-point contact or crossed cylindrical roller bearing generally USES oversize wheel bearings. Bearing is analyzed. studying systems: the blade of slurry system assembly, used to adjust the direction of the wind vane, mainly bear radial load, axial load and overturning moment. Requirements of the bearing has good sealing performance, high reliability, anti-corrosion, and flexible operation, such as more than 20 years of life. Typically USES four web contact or double bearing wheel bearing volleyball oversize. Spindle bearing: located in the wind leaf spindle, high work load, and compensation is required for the main shaft deformation. Therefore, it should has a good bearing performance, high load capacity, and long service life. Commonly used by optimizing the design of spherical roller bearing.
