You can just use pinions twice as long as the ring gears. I
How about a totally different tack. I was thinking about this some and might
possibly have an idea (probably not an original one and I'm sure there is good
reason it isn't done this way) that could eliminate the need for flexing parts
completely. What if you used two outer ring gears of the
Of course I hit send before I thought it through as the dog is bugging me non
stop for a doggy walk. Those darn pivots interfere with each other. Disks
can't be larger than the distance from the peak of the ellipse to the pivot
point of the other disk.
And we're back to a small contact
Half size won't quite work if you want a stub lining up with the cup.
But actually that is an interesting idea.
I'm sure the exact numbers could be determine mathematically but it was easier
to play with dimensions using the drawing tools. If the disks that slip over
the bearings were stacked
Did you mention the part number anywhere? How expensive are they?
I found this L44643 L44610 one inch ID tapered roller bearing and these are
super cheap replacement utility trailer bearings that come in kits including an
oil seal and even a cotter pin for a crown nut.
My kit was bought
Yes, 16 mm bearing can't help. I think what would be best is to use two
bearing and make them half the diameter of the inside of the cup. That
would be the largest possible size that would still fit.
That said, why not make a large size bearing from a small one by slipping a
plastic disk over

That bearing was picked because it is a common wheel bearing you can get
pretty cheap. (Double ball bearing). Plus you can pop it apart and grind
the race to create higher preload.

Nice to see that on Thingiverse.
A couple of things that come to mind. That is one huge bearing. For the
output shaft how much end play does it allow?

An output shaft like that with a couple of cheap tapered trailer bearings
instead of an unobtanium bearing. Provide stl/stp models of
