This is a masterpiece of paper engineering. The artist's site is here, but I cannot translate:

Try not to overload it. There's some other really impressive designs up too, but no documentation that I can find.

Easy, use a thin rod that goes up through the bottom cog, attaching to the center piece, and around the rod put a tight fitting pipe that attaches to the bottom cog. Piping is free to turn while the rod holds the center in place.

Well I guess this is /po/ so you could always just make the equivalent out of paper. Two tightly rolled up pieces of paper, one tighter than the other. Dunno how strong it would be, but would be a cheap alternative. Could also be made stronger by using wire or something similar for the middle rod part instead of the paper.

with what material this would be done?
with paper is not a good idea because the gears traction would probably destroy itself after a while
also, the shape of it and how firm it looks makes me think it's made out of another material
and how would be possible to assemble those strange kind of gears, such as the one on the top of the heart?

A long time ago in the early days of /po/, there was a similar papercraft like this, only it was a "paper gear cube" it also rotated and stuff.

Then /po/ discovered you could buy it, and included where tiny metal gears and rods, because the mechanism was not made out of paper.

Kinda took away the magic, and hard to share over download. ;)

So it means that long time ago it was on sale?
Because know the paper gear cube is not available for sale anymore
And even though it uses metal gears and rods, it still had paper parts
aren't those paper parts available?

It's not the paper pieces causing the spinning. They are just shaped like that to create the illusion that they do. In the center of the artwork there is a "hub" of small metal gears, with one pole going from top to bottom, and others sticking out at various angles. At one end of those poles is the gear in the central gear "hub", and on the other end is the paper part, that's not actually doing anything except sitting there and be pretty.
The amazing part is the time taken to work out where all the notches on the paper parts need to be so they don't interfere or block each other.

If you look closely, the center top spins, but every other parts remains in the same position to each other, and they rotate on one axle (the pole sticking out from the center). because they're a symmetrical, the effect is even more dramatic.

I think the guy is a clock maker.

It looks amazing, but the secret is in the small metal gears, after that you can put any shape you like on the end of the poles, and they can indeed be made out of paper, that doesn't really matter because there's no real wear and tear (they hardly touch if you do it right)

The engineering is a little difficult to work out, but once the conical gears are calculated the 3D is already half done.
Just extrude the conical gears beyond the envelope of the final size and boolean intersect with the heart solid. I also know how the inner frame of this can be done for an all cardstock construction, but it looks like the initial gear to redirect from the crank needs to be solid laminated cardstock due to the stress differential that came on my initial calculation run. Of course this is probably useless to all of you who don't use real CAD, I don't know how the lower level "3D" software operates.

Different types of gears also work differently. Like worm gears can turn a regular gear, but regular gears can't turn a worm gear. And bevel gears (that's how "conical gears" are called lol) especially a-symmetrical ones, don't just drive eachother the way you would expect, especially not just when put at the end of a stick.

>>199056
There are numerous paper automata that convert a vertical rotating motion into a horizontal one, without the need of solid laminated gears. That's the part that's NOT difficult lol... Google some paper automata sites and you'll see how simple that part is, If you just use normal cardstock like you would for regular papercrafts, the mechanism is sturdy enough already.
Getting the middle piece to spin is simple, the mechanism to get the other pieces to rotate turns out so small at the center gear hub (because of the conical shape, and they are at the small end...) that the bevel gears (that's how "conical gears" are called lol) turn out too small to make in paper with the kind of precision you'd need I think...
Low level software can do much of the stuff CAD programs can (more than enough for papercraft) only they make the interface easier for noobs to operate. ;)

It would be win to make this out of paper. It would be win to recreate this even with the metal parts. I hope someone has the time to do it, because I'd build it!

Like I said, converting a vertical rotating motion into a horizontal rotating motion has been done to death already, here's an example: http://guru2.karakasa.com/bevel_gear/bevel_e.html

But if you need "proof" because you can't possibly believe that it can be done, maybe you shouldn't "try and help" on this complex project but rather go do something a bit easier?
Let the rest of us not focus on the simple parts that are already solved, but focus on the difficult pieces for which it is not immediately apparant how (or even if) it can be done in just paper.

Quoted By: >>199255 >>199320

so where exactly are we up to then? it sounds like we can deal with the horizontal/vertical torque conversion, but even if we couldnt it wouldnt be a trajedy, cos the method used to get the whole thing to rotate is a pretty minor detail. ive been thinking about ways to make the whole bevel-gear-hearts thing work, i spent a while thinking about the inner workings as a centre piece with axles coming out from it, free to rotate, but upon further pondering i reckon that the axles from the centre need not rotate at all, but the gears themselves can just move freely on them. Maybe the rest of you already assumed this, and im far behind you, but to me it made it alot simpler to figure out once i realised this.
I dont really see what hard parts are left now. here's what im thinking:
- a "star" made out of lots of axles (11 if we follow the original design) coming together to a centre piece.
- the "heart pieces" to sit on the end of the "star arms", free to rotate but not free to slide off (thinking about the ones angled down)
- the bottom "star arm" going down into the box device where it connects to whatever torque drive we end up designing.
- a hollow pipe piece connected to the top of the box, going up around the aforementioned vertical "star arm", firmly connected to the bottom "heart piece" (this is what stops the heart from just rotating on the spot)

does this sound workable to everyone?

Test your idea and you'll see it again. ;)
Non-symmetrical / non-concentrical bevel gears are like God: they work in mysterious ways. ;)
If the axle is in the middle, most people can follow, but when the axle is off-center, the gears start blocking eachother and it's a real pain to sort it out, and of course the more you have, the more difficult it becomes.

But the hard part of getting the shapes of the paper "gears" at the end of the sticks right hasn't really changed. No matter what, the big problem was to get THOSE shapes right. The center gear hub is just a bunch of gears at different angles, but THEY COULD be symmetrical/concentric (and I think they are in the example) the hard part was and still is the shape of the a-symmetrical parts, and painstakingly make sure they don't block eachother while turning.

If you have the time, could you make a test example with just two simple a-symmetrical bevel gears? To get a start instead of theoretical discussion which is very hard to follow in your mind to see how the gears would rotate and so.

I understand what you're saying about asymmetrical gears being a bitch to work out, but these are symmetrical arent they? they're just cones, with teeth alone the sides, and cut off in a funny which forms a heart when they're all put together. The axle should still be right in the center of the gear.

I accidentally this board, but I just happened to notice something in the penguin bomb video.

Btw, the penguin is just a basic shape for the body and head with the sides opened. Put a rubber band in it connecting one side to the other, and it'll pull them together making it 3D unless you put pressure on it.

Locking mechanism is a bent piece of paper with a hole in the side. Another layer has a pin fitting in there. When you drop the penguin, the paper gets bent back and the pin comes free.

well i found a heart model and ive made the gear pieces. now i need to add axle holes (im sure theres a better word for "axle holes" but i dont know it), and im pretty much ready to start building.

here's what im planning to do with the gears. im thinking about the gears that lie on a horizontal axle, and the force of gravity (and others) that will be applied to those gears, and how well the stress will handled by the model.
Clearly in model A, the only thing keeping the axle-hole is the circular join of the cylinder to the bottom of the gear piece. Considering this will all be made of cardstock, thats pretty hopeless.
So im planning on making each gear in 2 parts; the first part with an axle-hole straight through it, as shown in model B, and the rest (including the trippy heart surface part) with a little more axle-hole-thing going into that. this means that when a lateral force is applied to the gearpiece, the stress is taken by both the bottom of the gearpiece, and the top of the first section of the gearpiece. having 2 separated points to recieve the stress greatly increases the strength of the overall object.
Does this sound right? If anyone has any more insight into the whole situation let me know.

Also: am i the only one still interested in building this thing? /po/ has been quiet on this topic the last few days.

I'd give it a go. I so-so looked at this thread after being impressed by the video but it had only got as far as the people not understanding how gears and right angles work etc. so thought it wouldn't get anywhere.

prompted me to look at what was so awesome, and he was right, you are doing an excellent job. infact i genuinely thought 'fuck, thats good'. I showed my girlfriend the video and she wow-ed so yeah i would give it a go, for a christmas present.

Also i really don't understand what you are getting at with the seperate gears etc, why not just do it like in your 3d model>>201039if each one extends in enough to meet then it will be fine surely? and then an axel to the middle hub? we will all just have to use really thick card anyway..

i dont know if this makes any difference. the green in the pics here show where the force is dissipated, and in the lower model its spread alot better.

i know if all of the gears are touching all the way to the middle, then there wont be heaps of room for things to move around laterally, so this problem shouldn't arise too often, but i think its worth it, because in the above model, that joint is just sooo weak that it'll buckle if you apply any pressure at all. and if the axle-hole isnt aligned properly then the gear won't move symmetrically and the whole system will fall apart, especially since we are using the actual paper gears to drive this model, unlike in the original design.

nah im having the gears move freely on the axles. i figure its easier to make a gearheartpiece that sits on the end of an axle, free to spin, than axles that join in the middle and rotate somehow on a central hub. so they need to be cylindrical.

going back to your two seperate ends to suport the gear, after the seperation have a wider bit on the end of the axle, a stopper if you will that won't fit back through the hole. This would then require more support in the gear i presume.

got a test in 30 mins so need to revise and go to it.. will draw a diagram later

something along these lines. It may throw the forces onto the stopper but should still be fairly well disipated.

Also i find it hard enough making closed shapes with pepakura, i usualy make with halo helmets with the open base (and even the assault rifle i found tricky tricky) so this is going to be nuts with all of the closed parts, espessially where things have to meet up and be just right :S I will just have to be patient when building for once.

yep i was thinking about something like that, and ive been trying to think of a better solution but i havent found one. i was liking the idea of being able to take the gears on/off the model whenever needed, for testing's sake (because if the gear is connected to the axle like that then i have to get it right the first time), but i guess that cant really be done because some of them would then fall off. btw the first part of the gear is still a gearpiece, its not just a support. see in>>201058
anyway i have to go to work today so i wont be able to update this anymore til tomorrow night.

maybe the axle could be de-attachable somewhere?
like, at the stopper?
make the axle with one diameter and the axle of the stopper with a slighly smaller diameter and attach them

another solution could be a screw but doing one with paper is not easy so I think this can be discarded

yep. there are 9 10tooth gears and 3 15tooth gears. so 2 turns of a big gear = 3 turns of a small gear = back to normal. if i follow the original designer's pattern, the mechanism to convert horizontal to vertical torgue will be 5:3, so that 5 turns of the handle = 3 turns of the driving (10 toothed) gear = whole period of movement.

>>201231
haha my brother posed the screw idea, and its a clever idea, but waaaaay to complex to do with paper. and not reliable and weak etc. i also considered the other ideas, but i think i'll settle for a stopper piece on the axle, inside the gear, in the join of the 2 halves of the existing gear design. ill just design the stopper piece such that it can be added, and not built into the axle itself (this makes the system stronger too). this way i'll be able to test the system until its all good, then i just need to slide the stopper onto the axle and glue it in the right position, then glue the pieces of the gear around it. it should be relatively easy. ill post what i come up with in sketchup when i get to it. exams coming up though so work will slow down next week. still the design might be complete before the end of the weekend.

i'm starting to think friction might come into play here, we are going to have alot or paper resting on paper and holding other paper in place while needing to slide over each other.. hopefully it will all run smoothly though.

what sort of size are you looking at making it? is it going to be like in OP?

Perhaps we're backwards on how to attach to the hub. Perhaps we should have the shafts attaches to the outer gear and rotate within the hub. After all, the only driving gear on the whole thing is at the tip of the heart.

I dont think that will work. that's what i initially planned to do, but i cant see a way for that to happen reliably. im trying to think of a way to keep all the axles together in the centre so that they can maintain their strength, and im having trouble with that. adding rotatableness would make it much harder. either way, if you have any ideas test them and let me know how it goes.

What I meant in>>202501was to essentially have stoppers inside and outside of the hub, having them attached to the rotatable shaft which would then connect to the outer gear shapes.

Since only the bottom gear is a driving gear, it's the only one that gets complicated. We essentially need to put a stationary column from the base to the hub to keep the hub from moving at all, then place a hollow shaft over that which connects to the bottom gear and the winding mechanism to turn the base and thereby the rest of the gears.

how about this: the bottom cog is stationary, with a hollow rod connectiong it to the base. it also is directly attached to the center piece. a rotating rod inside the hollow one goes up and drives the topmost cog. all other cogs are lined up on passive rods connected to the centerpiece, but can rotate freely. this way, no cog would fall out and the mechanics would be fairly simple without any hidden metal cogs in the center.

also, in the video, the pieces look like being made of papier-machè instead of plain paper. that would of course make them much more durable.

First of all, from viewing the video, this is not the approach as one notices that the bottom cog moves independently from the base. Also, connecting any gear solidly to the center would prevent any gear from turning, and if we wanted a stationary gear heart, we already have the 3D model for that and could easily make it. in such a way that it wouldn't move.

I've already run multiple schematics through my head on the functionality of this thing, and there's only two ways to make it work. Either the bottom gear drives the whole thing, or the bottom gear is stationary and the 2nd to bottom gears drive the upper shape along the y axis. Since the prior was employed in this model, I thought it best to stick with it since it's been tested and works.
