gear box study

[mbouwer]

The configuration that I have in mind.
This gives space for the active pitch control box.

[mbouwer]

Now first I want to modify stage no.1 for reduced weight and smaller dimensions.
Outside diam. of the new shaft is 50 mm.

[dbcollen]

Nice work, but aren't you putting the cart before the horse. You are building this transmission with no alternator that you are trying to match.

[mbouwer]

You're right,

But I think building small windmills is more fun, and there are more possibilities, being part of a team.
By showing my capabilities in this kind of studies I hope to once become part of a team.
 
In my region or elsewhere.

[mbouwer]

Next step is mounting the two gearboxes.
As a base the yaw bearing from Active Pitchcontrol Reply #830

The frame between the yaw bearing and gear box no. 1

[mbouwer]

Now adding stage 2

[mbouwer]

Mounting bracket for stage 2 on the yaw bearing.

[mbouwer]

Stage 2 + drive shaft.

[mbouwer]

Modified main axis flange to mount the blade suspension on.

[mbouwer]

Blade suspension. It is shaped such a way
that my previous made blade bearings fit.

[mbouwer]

For now I would like to end this gear box study.

[electrondady1]

congratulations on the completion of your machine mbouwer. i think it may be the most complex ever posted.

Nice...so how did it perform..?

[mbouwer]

Driven by the blades it produces the typical humming noise.
Later on I want to shape a three stage gearbox to get a greater ratio to drive a asynchronous 220/380 volt motor as a generator

[hiker]

Cool...next full size.?

Mbouwer,
It look great!
Well done!
I have enjoyed watching your progress every step of the way.
