APPLICATION IN WIND ENERGY SYSTEM
The yaw bearing is an important component of the yaw system, located at the bottom of the nacelle. It supports the entire mass of the main drive system of the wind turbine and transmits the aerodynamic thrust to the tower, enabling accurate and timely adjustment of the wind turbine's windward angle. The yaw bearing ensures that the wind turbine can track wind changes in a timely manner. The yaw and pitch bearings of wind turbine units generally adopt single-row or double-row four-point contact ball slewing bearings, which are subjected to the combined action of large axial force, radial force and overturning moment.
Wind turbine blade bearing is an important part of its transmission system, the bearing is installed between the blade and the hub, so that the blade can be rotated relative to its axis at different wind speeds, thus ensuring the normal operation of the wind turbine, which can withstand axial force, radial force and tilting moment at the same time, and this type of bearings has the ability to withstand higher tilting moment.
Through high-precision processing and assembly, these bearings are commonly used in wind turbine blade system.
