Description
Yaw bearings are core components installed at the bottom of the wind turbine nacelle, playing a crucial role in supporting the entire nacelle and enabling it to rotate horizontally to align with the wind direction. They are mainly designed as four - point contact ball slewing bearings or crossed roller slewing bearings. These structures are specially tailored to withstand the combined loads of huge overturning moments, axial loads, and radial loads from the nacelle and the wind. Many high - end models adopt the non - soft zone quenching technology, which eliminates the soft zone that is prone to appear in traditional induction quenching. This soft zone used to be a weak point with insufficient hardness and an early failure source. In addition, most yaw bearings are equipped with a double - sided sealing structure and optimized lubrication channels. These designs effectively prevent the intrusion of sand, dust, and moisture, thus ensuring stable operation under complex working conditions.
