In recent years, with the rapid economic development and population expansion, the demand for energy is also increasing. It directly leads to the aggravation of energy reduction and environmental pollution. The country is vigorously developing clean energy, and wind power is a mature, large-scale development and promising power generation method in new energy power generation technology. It has developed rapidly at home and abroad in recent years due to its safety and cleanliness. Wind turbine slewing bearing as an important part of mechanical equipment, the normal operation of wind turbine.

1. What is the wind turbine slewing bearing?

　Wind turbine slewing bearings can also be called wind power bearings. They are a special kind of bearings. They are used in harsh environments, have high maintenance costs and require long life. Slewing bearings for wind turbines mainly include: yaw bearings, pitch bearings, spindle bearings, variable speed bearings, box bearings, generator bearings.

The structural forms of slewing bearings for wind turbines mainly include four-point contact ball slewing bearings, crossed roller slewing bearings, cylindrical roller bearings, spherical roller bearings, and deep groove ball bearings. The yaw bearing is installed at the connection between the tower and the cockpit, and the pitch bearing is installed at the connection between the root of each blade and the hub.
　　

2. Structural form of wind power slewing bearing

The structural forms of bearings for wind turbines mainly include four-point contact ball slewing bearings, crossed roller slewing bearings, cylindrical roller bearings, spherical roller bearings, deep groove ball bearings, etc. The yaw bearing is installed at the connection between the tower and the cockpit, and the pitch bearing is installed at the connection between the root of each blade and the hub.

Judging from the current installation and usage, the pitch slewing bearings mostly use double-row four-point contact ball slewing bearings, the yaw slewing bearings mostly use single-row four-point contact ball slewing bearings, and a small amount of cross-roller slewing bearings or other forms are used.
