Wind-turbine yaw drive continues to exhibit a high rate of precipitate failure in spite of use of the best in current design practices. Since yaw bearing is one of the priciest components of a yaw drive in wind turbine, higher-than-expected failure rates increase cost of energy. Most of the problems in wind-turbine yaw drive appear to radiate from bearings. Yaw bearing is located between the Tower and Nacelle portion of the Wind Turbine and slews follow the wind direction. There is a gear located on the outer ring of the bearing and the Yaw Drive Motor is mated with this gear. The gear controls the angle control relative to the direction of the wind. This bearing assembly consists of an Outer ring, Inner ring, balls, and seal. Existing yaw bearing made up of Carbon and Low Alloyed steels, High Alloyed Steels and Super Alloys. In this yaw bearing constitutes fairly accurate 25 tones of weight. So we decided to reduce the weight of yaw bearings using composite materials. The modeling of yaw bearing is done using Pro-E and fatigue life and static loading capacity are analyzed by ANSYS. © 2015 Elsevier B.V., All rights reserved.
