mbouwer:
Chris Olson's writings always had my very great interest.
This is new inspiration.
SparWeb:
Well, Chris never made them that big!
How big is your turbine? Just trying to estimate the power, torque and speed are the first steps before knowing what you need in a gearbox - or whether one is necessary... and that depends on the choice of generator you make.
mbouwer:
In the first place it's only a study how I can weld a suitable gear box for a small windmill using scrapped gear wheels.
Now the gear ratio is 12.56 ( 4 and 3.14 )
