More Bearings
The main shaft bearing of a wind turbine is the main component that absorbs wind load and transmits load. Its performance not only affects the transmission efficiency, but also determines the maintenance cost of the main drive chain.
Due to the harsh working conditions and long-life and high-reliability requirements of wind turbines, main shaft bearings have high technical complexity, which is recognized as one of the most difficult technologies, and has become an important factor affecting the development of wind power manufacturing.
The main shaft bearing includes: double-row spherical roller bearings, tapered roller bearings, cylindrical roller bearings, double-row tapered roller bearings, etc.
Main shaft bearings also have high requirements for material, lubrication, sealing, coating, cage and other aspects.
