V22 Integrated bed frame
Integrated bed frame
The trend is that turbines and thus turbine components are larger. Thus, efforts have been made to reduce mass for the largest nacelle components, in this case bed frame and main bearing housing.
The known solution is having a separate bearing housing with 4 feet attached to the separate bed frame. This solution is widely used for decades, but more problematic when the turbines get larger. Especially the bolted connections are problematic, but also the deflection during loading disturbs the main bearing interfaces, which may decrease the bearing lifetime.
By playing with stress flow and integrating main bearing housing and bed frame it has been achieved to reduce the total mass of main bearing housing and bed frame by 25%
The main bearing interfaces have been optimized using the optimized structure. By that an improvement of the same front bearing lifetime is improved by 30%
