Casting Wind Turbine Main Shaft QT500-7 EN-GJS-500-7 Heavy Casting Fountry

Casting Main Shaft For Wind Turbine QT500-7 EN-GJS-500-7 Heavy Casting Fountry From China

A wind turbine generates electricity by harnessing the power of wind. A wind turbine shaft is the most central part of a wind turbine, subjected to highly dynamic loads and operating conditions. The energy from wind is converted into mechanical energy with the help of blades and rotors, which is then transferred to a generator through the gear box and shaft.

The wind turbine generally consists of two types of shafts i.e. main shaft and generator shaft. The main shaft is a low speed shaft with the turbine rotor bolted through a strong disc. The generator shaft is a high speed shaft coupled with the output shaft of the gearbox.

Advantages for the casting main shaft compared with the forging main shaft

• Casting molding, reduce the amount of processing, lower than forging cost.
• The outer ring metal shape ensures the densification of the spindle surface.
• The internal quality of the spindle is ensured by optimizing the process through simulation.
• Ensure the safety of production process through reasonable design of tooling.
