Wind turbine main shaft bearings are key components in wind turbine generator sets, and their main function is to support the wind turbine to rotate and generate electricity. This type of bearing usually adopts a two-point or multi-point support design, and the inner ring is installed on the main shaft to support the rotation of the main shaft. Wind turbine main shaft bearings are widely used in direct-drive wind power generation devices without main shafts and gearboxes, especially in large-scale megawatt-level wind power generation equipment and offshore wind turbines.

Main functions and features:

Support wind turbine rotation and power generation: In wind turbines with main shafts and gearboxes, main shaft bearings play a key role as the main support.

Bear complex loads: It is necessary to bear the complex loads of wind turbine hubs, blades and wind loads, and cope with harsh natural conditions such as rain, wind, sand, and salt spray.

Design and manufacturing requirements: Use materials with high strength, high toughness and good wear resistance, such as high-strength steel, special alloys, etc., and perform precision machining, heat treatment and surface treatment to improve performance and reliability
