1.The structural characteristics of wind power bearings
1.1 The structural characteristics of yaw bearings and blade bearings
The structure of the yaw bearing and blade bearings are single-row or double-row four-point contact ball slewing bearings.
The blade bearings endure the axial force, radial force and turning moment produced by both the blade and wind swept blade,and though the adjustment of the blade structure, it can ensure the inclination angle of the blade relative to the different wind speed.
The yaw bearings are in the top of the tower, which support the entire cabin of the wind turbine and bear the axial force, radial force and overturning moment produced by wind swept blade, and though the yaw adjustment of the yaw driving structure, it can ensure the directionality of the pod on the positive wind power.
1.2 The structural characteristics of main bearings
Due to different design of the turbine transmission system, the main bearings have a lot of structure style.
Due to the wind power bearings need to ensure the high reliability and long life, ZWZ calculate every wind turbine for the bearing type selection, which includes strength calculation,life calculation, bolt strength calculations, and tooth strength calculation.
ZWZ can execute synchronous design to the bearing selection with customer's turbine design.
Before customers select the bearings, they need to provide bearing working load(static load,fatigue load spectrum), load coordinate system and driveline structure layout and other information to ZWZ,
ZWZ calculates the bearing type selection based on the bearing application condition.
2.The assembly and maintenance of the wind power bearings
Due to the individual design of the wind power bearings, ZWZ will provide customers with detailed bearing assembly maintenance instructions to the customers when customers select ZWZ bearings
