Product Description

The Slewing bearing is the core component of the wind turbine, Slewing bearing of the wind turbine is used as an extra large bearing, which is mainly used for the pitch and yaw system: the pitch bearing is used to connect the wheel and the blade, and the yaw bearing is used for Connect the tower and the unit. Wind power slewing bearing is very difficult to repair due to its large size and difficult installation location; in addition, under the variable working environment of the wind farm, the component is complicated to load, and it is very difficult to disassemble and maintain, resulting in maintenance costs higher. Moreover, once the slewing bearing fails, it will directly affect the working performance of the wind turbine, and even cause a shutdown.
Wind turbines currently mostly adopt a double-row ball four-point contact ball bearing structure to meet the varying demands of different wind speeds on the blade angle. In recent years, the reliability problems caused by simple and rude increase in blade length even cannot be avoided by mainstream equipment manufacturers in the industry. The failure of batch pitch bearings has appeared, which has become a pain point for the entire domestic and foreign industries, and the industry needs to reflect.
