Wind Power Generation

With the development of economy and social improvement, people put forward higher and higher requirement for energy, to find new energy is our urgent subject in nowadays.

Wind driven generation bearings divided into three parts: Yaw bearing, pitch bearing, drive system(spindle and gearbox). Every wind driven generation use one set of yaw bearing and three set of pitch bearing. The installation cost is expensive since the wind driven generation lifetime required is 20 years, so the bearings need lifetime reach to 20 years too. 

Key Functions of Bearings in Wind Turbines

Support Rotating Components: Bearings support the main shaft, gearbox, and generator rotor, allowing them to rotate smoothly.

Reduce Friction: By minimizing friction between moving parts, bearings improve efficiency and reduce wear.

Handle Loads: Wind turbine bearings must withstand radial, axial, and moment loads caused by wind forces, rotor weight, and operational stresses.

Ensure Reliability: High-quality bearings contribute to the longevity and reliability of wind turbines, reducing maintenance costs and downtime.

LYNBC have optimize structure design with small clearance, the bearing rings hardness is HB229-269, which assure it will not have plastic deformation when receive big impact. Bearing raceway hardness with surface hardening , which reach to HRC55-62. It will increase the bearing lifetime. In order to against dust and corrosion ,we design the bearings with anti-rust cap, zinc plating and painting in the bearing surface.

The right bearings support for wind power generation:slewing bearing, cylindrical roller bearing, angular contact ball bearing, deep groove ball bearing, spherical roller bearing.

Innovations in Wind Turbine Bearings

Advanced Materials: Use of high-performance steels and coatings to enhance durability and reduce wear.

Sealing Solutions: Improved seals to protect bearings from contaminants and moisture.

Condition Monitoring: Integration of sensors to monitor bearing health and predict failures.

Lubrication Systems: Automated lubrication systems to ensure optimal performance and extend bearing life.

Bearings are indispensable in wind power generation, ensuring the smooth and efficient operation of wind turbines. Advances in bearing technology continue to improve the reliability and performance of wind turbines, contributing to the growth of renewable energy. Proper selection, installation, and maintenance of bearings are essential to maximize the lifespan and efficiency of wind power systems.
