92 Gears - Animation - Final by TaffGoch 92 Gears - Animation - Final by TaffGoch
I took some "artistic license" with the gears. Can you spot it?

Red gears: 20 teeth, 12 count

Yellow gears: 13 teeth, 60 count

Red gears aligned with icosahedron vertices Blue gears aligned with dodecahedron vertices

Polyhedral basis for red & blue gears: buckyball

Regarding all 92 gears, the central rotation axes are aligned with the vertices of a frequency 3v, class-I geodesic tessellation of an icosahedron

So... is there a Kickstarter coming to print some of these as kinetic sculptures?

Unfortunately, despite gaining popularity and availability, 3D-printing remains too expensive.
For example, I submitted the model to Shapeways, and a 3-inch ball would cost ~$200.

I have been working on developing a casting pattern for each of the 3 gear configurations, which could then serve to produce molds for resin casting. With my schedule, this may require the snowbound winter months, to provide enough free time in my workshop.

(I'm aiming for a ball that is, at least, 9-inches in diameter.)

Your stuff is absolutely amazing! Let me know if its OK for me to save this video I made. [link]

Paul,

Your posting of a YouTube video is quite alright, as I see that you have included a proper attribution.

Amazing. Considder using MNG. Lossless and no 256 color limit like GIF. :meow:

I have software that will generate MNG animations. (They do, indeed, look great.)

Trouble is, there is very poor browser support for MNGs. There is better support for APNGs, but, even then, all browsers do not support APNGs.

Reducing to 256-color GIFs is okay-by-me, as it reduces file size to something manageable for online display, by all browsers.

You are of course, and sadly enough, correct. While APNG is technically better and works fully in Opera and Firefox there is very few software to make them oddly enough so even less known as a animation format. However, either serve well for storing the source animation locally and you mentioned JASC Animation Shop which supports MNG out of the box. Perhaps a middle road solution could be to just provide a link to either in addition to the GIF. :meow:

My solution: 92 Gears - Flash Animation

(Rather large file, though....)

Taking another shot at the "artistic license", I'll say that the face of the gear teeth appear to be of a spur gear type, yet it is clear that they are all helical gears.

Yep, it's the gear-tooth configuration.

These are hypoid gears, which only work when the axis shafts are skewed. In this model the axes are not skewed, but instead, all intersect at the center of the sphere. In a real-world example of this animation, the hypoid teeth would bind.

Hypoid gears have "curved" teeth, as apparent above. Spiral and conical gear teeth would work (not bind.) My previously-posted "study" deviations depict spiral teeth. If I were building this "device," as a sculpture, it would require the use of spiral or conical gear teeth.

Why take such license? Hypoid gears look wicked cool!

you really have kicked it up a gear with this one (Sorry!)

artistic license? not a clue, but its great work, have you posted this over at sketchucation and kerkythea forum? If not you should.

Also how did you animate this?

I animated by rotating each gear, in increments of 1/6th of the gear pitch (tooth-to-tooth angle.) The animation GIF contains just 6 frames.

I only have to rotate one instance of each gear component; red, yellow & blue. I use a component-in-component nesting "trick" to cause all other instances of a gear-component to rotate by the same angle and direction.

The camera position & angle are preserved by a "scene."

pure efficiency in work flow, just brilliant :jawdrop:

I think of the faces of a poly well fusion device as each having a spin. For that reason, your recent animations make me think of poly well fusion

Re: artistic license; is it that none of the gear faces actually touch each other?

More esoteric than that.

(I hardly expect a correct answer, unless a mechanical engineer sees it.)

I'll give it 24 hours, then I'll answer.

I -am- a mechanical engineer! I'll have to look at it again!
