Wind turbine slewing bearing is one of the important parts of the wind turbine. Wind turbine converts wind energy into mechanical energy by absorbing wind energy and then converts it into electric energy to realize wind power generation. Wind power system mainly includes main rotating system, pitch system, and yaw system. The components of each system basically contain slewing bearings, such as pitch slewing bearing, yaw slewing bearing, and the quality of wind power slewing bearings directly determines whether the wind power system can operate normally.

1, wind turbine slewing bearing composition
Wind power slewing bearing is a large slewing bearing, which consists of four parts: inner ring, outer ring, rolling element and isolation block. Different from ordinary slewing bearing, wind turbine slewing bearing needs to withstand greater torque, so each component should also be reinforced and processed so that they can meet the needs of the wind power system. After all, the cost of wind power generation is inherently high, and once replaced or repaired, it will cause great losses.

 

2, the characteristics of wind turbine slewing bearing
Usually, the use environment of wind turbine slewing bearing is bad, so the better structures and components are needed. therefore, the structure and component quality of wind power slewing bearings are good. But there will be damage inevitably. Once the slewing bearing is damaged, the replacement is not only costly but also delays power generation. Wind power generation is a continuous process, that is why wind power generation requires a high-life slewing bearing. Another major feature of wind turbine slewing bearings is high life.

 

3, the selection of wind turbine slewing bearing
There are many types of slewing bearings, such as double row ball slewing bearings, single row cross roller slewing bearings, three rows roller slewing bearings and ball and roller combined slewing bearings, etc. The selection of wind power slewing bearings is mainly three-row roller slewing bearing and cross roller slewing bearing, these two types slewing bearings have the high bearing capacity and can better meet the needs of wind power fermentation.

 

4, wind power slewing bearing manufacturers
Since wind power slewing bearings are so important, we must pay more attention to the selection of wind power slewing bearing manufacturers. We must pay attention not only to the price but also to the manufacturer’s production qualifications. Is there any qualification and experience in producing wind turbine slewing bearings? How about the slewing bearing quality, etc. in order to ensure that the wind turbine slewing bearing can run for a long time.

 

In general, wind turbine slewing bearing is important components of wind power equipment, such as pitch bearings and yaw bearings. Wind turbine slewing bearing is generally used in harsh environments, so wind turbine slewing bearings are required to have better performance and longer life. The life expectancy is more important to choose a suitable manufacturer to make the wind turbine slewing bearing run for a long time.
