ZCCCT Tools Application in Wind Power Industry ——Main Shaft

Windpower, as a new energy resource stored huge amount of energy, wind powerreserves is around 2.74×109MW in the world. Amount them, 2×107MW are availableto be harnessed. It is 10 times larger than total amount of applicable waterenergy on the earth. Wind power has caused more and more attention across theworld.

Mainshaft is a key component that connecting hub and gearbox, made of 34CrNiMo6、42CrMo4, etc. It is usedto transfer revolving torque of rotor blade to gearbox. Heave tight coupling ismost used device for connecting main shaft and gearbox, it guaranteesconcentric between main shaft and gearbox, also is able to avoid maintenance inoperation.
