The key technology of wind power bearing

Wind power bearing manufacturing, to meet the technical requirements on the basis of the above, with special focus on the following key technology research and application -
Steel quality control techniques and control measures;
Turntable bearing ring surface hardening hardness, effective case depth control, quenching cracks to prevent;
Tapered roller Taper bearing, cylindrical roller bearings ball base surface in contact with the wall position and shape optimization;
Spherical Roller Bearings, roller and outer face hardness and roughness matching optimization;
Rings and rolling elements NDT;
The best control of residual austenite content, etc.
