The best thing I can say about that web site is; it is recalcitrant :)

"The IFB consists of a double-cantilever pin supporting the bearing and gear.
The cantilevered pin attaches to the carrier wall, and a cantilevered sleeve
mounts to the free end of the pin. Gears and bearings mount on the sleeve."

"Simply stated, external forces on the gear make "the pin bend in one
direction, the sleeve bend in the opposite direction, and misalignment
angle at the gear face remains virtually zero," says Fox."


Interesting design but certain mechanical things don't scale up well.
Most well designed planetarys have a certain amount of flexibility built
in to handle this problem. They also have straddle mounted pinion shafts.
I was rather surprised when Ford changed the low modulus aluminum for
steel in the planet carrier for the six pinion version.
