It would be cool to have this in a museum and every visitor can turn it and see how long it takes for it to turn, I'm sure if you contacted a museum that they would take it.
+Lyrik Tech it will actually never complete a full revelation because the plastic used to 3d print it on the first gear would wear our and break FAR before you got anywhere close to a billion revelations.
Concerned Person Reduction gears are simply a set of gears which require an input of significantly more turns than they output. Think about a bicycle on its fastest gear. you roate the pedals once, but the rear wheel rotates 3 or 4 times. This is the same concept but in reverce. many museums have extream reduction gears set up where a motor is constantly spinning turning the gears, but the output seems to not move at all, because of the extreme reduction.
This is a three and a half year old video, so I don’t know if you’ll see this comment, but I just wanted to say how impressed I was with your making use of the already eccentric motion of the blue gear to drive the second stage of each section. Beautiful design.
Technically no, time can be "a" fourth dimension after our three dimensions but it's not "the". However if we use time as the fourth dimension then, then in fact we would be using a 4D 3D-printing material and change its 3D form at one part of the 4D object.
Some back of the napkin math suggests that 1,000,000,000 is a reasonable estimate for the number of revolutions a car engine would make in its lifetime, so putting one of these in a dashboard hooked up before the transmission would put 1,000,000,000 in human scale.
Wow. Thank you Oscar. I have just begun learning about gears and gear trains in pursuit of my building some wooden geared grandfather clocks. I know my understanding is limited but wow, you seem to be so far in advance of any and all others, not just theorising phenomenal gear reductions with a few very small parts but you have proven your theories by building working prototypes. I can just imagine these built out of the finest titanium alloys etc. wow, I take my hat off to you Sir, you have truly achieved magnificence. So simply ingenious, I hope that you go far for you truly deserve the greatest accolades for your most clever solutions to such vexing problems. So clever, thank you for sharing your genius with us, you made my day, thank you
you have a lot of reduction gear videos. and they are all really cool feats of engineering. But the neanderthal inside of me wants to see a multiplication gear. something where you spin one side once, and the other side spins 100 times, 1000 times or more.
friction is that direction and the strength of the material would be the limiting factor sadly...if it was infinitely strong and frictionless lol well you'd only have to touch the ouput end for the input to spin up to lightspeed!!
Thanks for sharing this one Oskar! If you had a whole year, I wondered how fast you would have to turn this to make a full revolution on the slowest part! I did the math, but decided to share if anybody else was curious like I was: 1 Billion turns / 365.25 days in a year (included leap year because... Earth moves around the Sun that way) = 2,737,851 turns per day. / 24 = 114,155 turns per hour. / 60 = 1,903 turns per minute or RPM "revolutions per minute". / 60 = 32 turns per second. In order to make this awesome toy survive nearly 2 thousand RPMs for a solid year, you would have to manufacture a version of it made out of very strong and durable materials that are low friction.
Avant-Tom if somehow friction was greatly reduced and made into some strong metal and put on a machine running at many rpm this could push 1000s of tons of pounds from place to place
+Kabitu1 it never measures at :3 its always :1 thats the original scale.. if u do :3 thats a 3/1 scale of the power which will be 10bilions and smth to 1 based on ur saying
Hi, I have an idea for a puzzle but I don't have the necessary skills to design it. I figured that asking here might lead down the correct rabbit hole to getting it made in some regard. It's a puzzle bracelet. Similar to a puzzle ring, but ideally the final step(s) would shrink down its diameter to fit snugly around a wrist and lock it on. I have more potential constraints, but I do understand the more limits on a design the less inspired the result can turn out. Thank you for your attention, good luck making up more puzzles.
U deserve a Nobel Oskar. If someone could power your contraption backwards then you have beaten Einstein's relativity theory . The last gear would move faster than light. I hope you already patended this
This device can be used on instruments that require high-precision adjustment, and does not require a computer or even electricity. In theory, it can be adjusted manually to achieve an accuracy of one billionth of a centimeter, which is really amazing!
+Kabitu1 but would the gears survive so many cycles? That's just 3D printed plastic. it would crumble in a few thousand turns i guess. I think putting a drill to spin it until it breaks is a good idea.
+Peter LeRoy “Apl 527097” Barnes physics - in gear reduction mechanisms, the reduced side (the red ring) requires exponentially more energy to turn. It would take a fuckload of energy & the gears probably wouldnt survive the process.
I have seen some people in the comments suggest that you have a museum put one of these in and see how long it would take them to do 1 revolution of the red gear. Assuming that 250 visitors could put in an average 50 cranks per person every day, it would take a little under 235 and half years to complete 1 revolution of the outer gear.
the first gear gives 32 teeth and if all the gear teeth stage are same ( it has 3 stage ) first stage 1024 reduction second stage 1048576 reduction third and final stage 1073741824 reduction
This would be great if you can put a cranck in each of the stages, so a person could start with small reductions and fine tune to a bigger and bigger reduction. If you have access to each stage this could be used for, say, microscopic manipulators or micro surgery operations.
Take off the other stages, and hook up the last output stage and see how much mass it can move before it destroys itself. That's your number, no amount of other input stages are going to make it move more than it can move at self destruction.. Find a heavy 10 pound ball, and a stick that can just barely move the ball without breaking. Moving the stick twice as accurately or with twice the advantage on your end won't make it move a 20 pound ball, it'll still break just over 10..
+gredangeo That would be fairly easy. This one has three stages of 1000:1. I can easily add another one or more 1000:1 stages and the contraption would remain about equally compact.
Would it be at all possible to perhaps have a sped up recording of this thing turning? Obviously not by hand, but maybe you could bolt this down, hook an electric motor to it and film the result. It would be entertaining to see a turn of it, for some reason, lol.
For me it looks more like the first 2 "stages" don't really affect the last stage, because the yellow rings slide within the blue rings of the next stage, but this sliding is not eccentric by itself, but driven by the same eccentric motion of the first stage. therefore only one stage is "active" for the movement of the red ring
This is really awesome. What would the maximum load be for the design, I wonder? I imagine so much torque would be generated that most materials might eventually shear. It would still be really cool to see it try to move something like a freight train, as you suggested before.
Lemme put it to you this way. If you put 3 of these in a row and added a rack and pinion system to the input so that when you push on it it turns the initial knob with a rack that is IMMENSELY LONG, you could take a pencil and place it on top and literally shove the ENTIRE PLANET!!!!!!
That's not what I was actually asking. I was referring to the practical limits of the material strength. You can't push the entire planet with a set of plastic gears.
+Joshua Smith Cycloidal gears can't be back driven unfortunately. If they could, the torque needed to turn it would be so ridiculously high that you'd break it before you got a fraction of a degree of rotation
+Chris Licata Hmm...In order to get something up to high speed we have to increase speed slowly withing the bounds of the materials given. We would need to know the shear on the gear teeth and resisting friction. I suppose we would also need to know at what speed the material itself would disintegrate.
+Joshua Smith if you could rotate the output at 1 revolution per minute, the input with the crank would rotate 1 billion times per minute. With a crank 2 inches long, you achieve a linear velocity of about 2.1^8 meters/second. Darn close to the speed of light
So you could add as many "reductions" as you wanted by factors of 3 figures per gear. You could have a trillion and a quadrillion! Does it get harder to turn the more gears you add because of internal friction and resistance?
Can you demonstrate the ratio other way around by add a handle to the outer gear and turning it by hand, and observing the inside gear turning really fast?
Is motion reliably transmitted to the second stage? The yellow output ring of the first stage must drive the blue gear of the second stage, but I can't envision how that happens.
Since several people have already answered your question, I'm just going to point out that if you were turning this every day for a full work day, it would take a lifetime to go around once. Just pointing out the magnitude of a billion.
1073741824 I get how the grinder gear works but for the life of me I can't wrap my brain around how you're driving one stage of the reduction with the previous one. Can you explain please?
Does a gear system like this work in reverse? Like can this be used to achieve massive RPMs with a VERY small amount of torque? Not sure if that would work with the grinder gears, but I'd like to see.
This is fantastic! You could make a remote control electronic submarine 1/1,000,000,000 the size of a regular remote-control electronic submarine! You should be in big business, dude!
What would be interesting would be to hook it up to an RC Turbine engine Direct or 2 Stage and watch it work. A lot of them spin at > 100,000 RPM. You would be able to see it work rather quick.
Not really a problem of torque, its that this type of gearing can only be used for reduction, its not like a normal gear set that if you input power on the output side and he input turns with an inverse of the gear ratio.
Question? If in a gear reduction aparatus the slow turning end gear is turned very slowly, will this spin the initial gear super fast? Please demonstrate!!
If the reduction per ring gear set is 1:32, why do think the ratio is squared? Three compounding rings of 1:32 should produce about 1:32,768. This should be easy enough to physically check.
can you change the design so it would work in reverse like you turn one side 1 and other side turns 1 billion times. and if so how difficult would it be to turn with no load
So, if TrackpadProductions (another commenter) is right, this has a gearing ratio of 1 to 1074741824. That means that if you spun that first gear once per second constantly, then it would take approximately 34.5 years for the red gear to rotate once. Holy shit.
whoever keeps asking him to turn it from the last gear must realize that he would need incredible hulk strength to do so and would break it in the process. not to mention that even if it were made of a space age frictionless material strong enough to withstand that power, if he could spin the hard side at 1 rpm, the first gear with the handle would be moving faster than the speed of light.
Is it possible to turn the "reduced" side and get a lot of revolutions on the other side? i know its probably impossible, or very hard in practice, but could you explain how a situation like this might work?
There exists an equation in gearing theory that calculates whether a gear is backward turnable or not, see www.amazon.com/Kinematic-Geometry-Gearing-David-Dooner/dp/1119950945. This design definitely is not backward turnable.
It would be cool to have this in a museum and every visitor can turn it and see how long it takes for it to turn, I'm sure if you contacted a museum that they would take it.
+Lyrik Tech Wow, even if it was spun 10,000 times per day, it would take almost 300 years to complete a turn!
+Lyrik Tech it will actually never complete a full revelation because the plastic used to 3d print it on the first gear would wear our and break FAR before you got anywhere close to a billion revelations.
Sam Jaffe Well then they could always just print a new gear and put it as close as they can to where the previous wore out.
+anothermoth there is one in the Ontario Science center as well. probably allot of museums have something like this.
Concerned Person Reduction gears are simply a set of gears which require an input of significantly more turns than they output.

Thank you!
The focus of your videos is the mathematics and logic behind these devices, but the craftsmanship should get some attention too. Very cool devices.
Thank you for the compliment. As for craftsmanship, most of my stuff is 3D printed.
What software do you use to design these? Very cool.
Exact would be 32^6, so 1,073,741,824.
3D-printing is quite straight forward: you print a 4D object first, and then just cut the 4th dimension.
Lol
John Smith The 4th dimension is time.
Technically no, time can be "a" fourth dimension after our three dimensions but it's not "the". However if we use time as the fourth dimension then, then in fact we would be using a 4D 3D-printing material and change its 3D form at one part of the 4D object.

I am impressed that the little device fits so many gears.

You would need an incredible amount of torque on the input gear for that. I would probably break the device.

@@chrisblythe1006 the output would also need to be mass less for it to accelerate to light speed
Based off what you said in the video, the exact gearing ratio is 1,073,741,824:1, or (32²)³ to 1.
precisely 1.0 GB of reduction (2^30)
Thanks for sharing this one Oskar! If you had a whole year, I wondered how fast you would have to turn this to make a full revolution on the slowest part! I did the math, but decided to share if anybody else was curious like I was:

this guy is like Archimedes. He could move the earth with this kind of stuff "give me a lever and place to stand and I will move the earth.
I doubt this mechanism can transfer much torque, but it's cool little mechanism.
I can jump and move the world, just not very far and it moves right back.

+TrackpadProductions That seems right
+TackStash779 yup

all i have to say is a big thumbs up for you Oskar!
This device can be used on instruments that require high-precision adjustment, and does not require a computer or even electricity. In theory, it can be adjusted manually to achieve an accuracy of one billionth of a centimeter, which is really amazing!
I just like imagining how much force it would require to turn the final gear once and have the crank rotate one billion times.
Firstly, I'm glad you didn't actually shart, I was a little worried for a second.Second, the exact gearing ratio would be 1:1,073,741,824 (i.e., 2^30)
i wonder if it will survive one full turn...
+lichtsuchender You could turn it 10 rounds a second for 3.4 years, that should do it.
+Kabitu1 but would the gears survive so many cycles? That's just 3D printed plastic. it would crumble in a few thousand turns i guess. I think putting a drill to spin it until it breaks is a good idea.
+lichtsuchender How about turning it by the red part...
+Danilo Mello hook it up to a tesla turbine running on compressed air
+Peter LeRoy “Apl 527097” Barnes physics - in gear reduction mechanisms, the reduced side (the red ring) requires exponentially more energy to turn. It would take a fuckload of energy & the gears probably wouldnt survive the process.
A more detailed video on this mechanism and many others invented and developed would be fascinating.
I agree. However, I am not a professional TH-camr, and such videos take a lot of time and effort to create.
I have seen some people in the comments suggest that you have a museum put one of these in and see how long it would take them to do 1 revolution of the red gear. Assuming that 250 visitors could put in an average 50 cranks per person every day, it would take a little under 235 and half years to complete 1 revolution of the outer gear.
¡Happy birthday Oskar! ¡Keep on doing awesome things! ^^
Each stage is 32^2, or 1,024, to one. Cube it, because of three modules, and you get the final ratio of 1,073,741,824:1.
the first gear gives 32 teeth and if all the gear teeth stage are same ( it has 3 stage )
first stage 1024 reduction
second stage 1048576 reduction
third and final stage 1073741824 reduction
This would be great if you can put a cranck in each of the stages, so a person could start with small reductions and fine tune to a bigger and bigger reduction. If you have access to each stage this could be used for, say, microscopic manipulators or micro surgery operations.
Surgery?*
Oskar + Gears = Pure Love #True

Would it be at all possible to perhaps have a sped up recording of this thing turning? Obviously not by hand, but maybe you could bolt this down, hook an electric motor to it and film the result. It would be entertaining to see a turn of it, for some reason, lol.
What are some practical uses for such extreme reduction? Would this provide a more accurate clock?
put one in a museum and have people turn it till it hits 1 billion

I can see a gearing mechanism like this being used in a heavy industry business like an oil field or something.
The exact gearing ratio is 1,073,741,824 to 1. Dat torque! Pretty much cracking a planet with a gear system that can be held!
torque amount? is it like the other one and almost nothing, or is it real and powerful?
Great design.
The exact gearing ratio is 1073741824, or 32^6.
can you turn a second motor with it? like a really small motor? please give me your advise thank you
I'm curious if it would retain its power delivery. such a large reduction would be very strong. does this type of gear system keep its strength?
I would like to see a gear that has like a 1:1000 ratio. So turn it 1 rotation, and the final one turns 1000 times. That would be cool.
I'd like to see you build one and measure how much torque you can generate before it fails
This is really awesome. What would the maximum load be for the design, I wonder? I imagine so much torque would be generated that most materials might eventually shear. It would still be really cool to see it try to move something like a freight train, as you suggested before.
Lemme put it to you this way. If you put 3 of these in a row and added a rack and pinion system to the input so that when you push on it it turns the initial knob with a rack that is IMMENSELY LONG, you could take a pencil and place it on top and literally shove the ENTIRE PLANET!!!!!!
how could this lift something i don't understand where you would play the object you are trying to lift
That's not what I was actually asking. I was referring to the practical limits of the material strength. You can't push the entire planet with a set of plastic gears.
Can you go backwards with this gear ratio and get super high speeds?
+Jonathan Nypan I would think the F=ma would also get in the way perhaps more so as the acceleration would be enormous.
+Joshua Smith If anyone were to make an enormous version of this..
+Joshua Smith Cycloidal gears can't be back driven unfortunately. If they could, the torque needed to turn it would be so ridiculously high that you'd break it before you got a fraction of a degree of rotation
+Chris Licata Hmm...In order to get something up to high speed we have to increase speed slowly withing the bounds of the materials given. We would need to know the shear on the gear teeth and resisting friction. I suppose we would also need to know at what speed the material itself would disintegrate.
+Joshua Smith if you could rotate the output at 1 revolution per minute, the input with the crank would rotate 1 billion times per minute. With a crank 2 inches long, you achieve a linear velocity of about 2.1^8 meters/second. Darn close to the speed of light
So you could add as many "reductions" as you wanted by factors of 3 figures per gear. You could have a trillion and a quadrillion! Does it get harder to turn the more gears you add because of internal friction and resistance?
Can you demonstrate the ratio other way around by add a handle to the outer gear and turning it by hand, and observing the inside gear turning really fast?
Hi, I think this is fantastic.Could you describe where the eccentricity is generated ?Thank you.
Is it what's inside those compact torque multipliers used to remove trucks nuts by hand ?
A billion to one ratio would be great for super-precise microscopes, like electron microscopes.
I love how they look like nineties kids toys!
Is motion reliably transmitted to the second stage? The yellow output ring of the first stage must drive the blue gear of the second stage, but I can't envision how that happens.
If you could turn the big gear once and the other on would turn a billion times? Is turning the big gear once an impossible thing to do?
Since several people have already answered your question, I'm just going to point out that if you were turning this every day for a full work day, it would take a lifetime to go around once. Just pointing out the magnitude of a billion.
+TinBryn well if you turned it once per second 24/7, it would only take a bit over 31 years to go around once.
Maybe this device is useful for slowly opening mustard jars ;) Grats!
1073741824 I get how the grinder gear works but for the life of me I can't wrap my brain around how you're driving one stage of the reduction with the previous one. Can you explain please?
Does a gear system like this work in reverse? Like can this be used to achieve massive RPMs with a VERY small amount of torque? Not sure if that would work with the grinder gears, but I'd like to see.
+Alex Hauser Small amount of torque being on the output, obviously
Nice vid... But Am looking for extreme speed increase but can't find it... were should I look?
Does this also increase the torque 1 billion to 1?
And what can it be used for?
What would you get if you had 4 stages or maybe 5 or 6..
This is fantastic!
You could make a remote control electronic submarine 1/1,000,000,000 the size of a regular remote-control electronic submarine! You should be in big business, dude!
So is it possible to manually spin the final piece or would it just break?
The exact gearing ratio is (32^2)^3 = 1,073,741,824.
could you run it backwards?
eg. apply sufficient force to the red ring and cause the handle to turn?
What would be interesting would be to hook it up to an RC Turbine engine Direct or 2 Stage and watch it work. A lot of them spin at > 100,000 RPM. You would be able to see it work rather quick.
what would happen if you spun it from the red gear? would the handle go apeshit?
well maybe if physics wasn't a thing.
Pretty sure, due to the design using the ‘grinder gears’ that sort of move rather than rotate, nothing would happen short of getting caught on itsself
What would happen if you turn the red knob on the front? Would the crank spin unimaginably fast, or would it be impossible to turn?
Impossible to turn it, too high torque.
Not really a problem of torque, its that this type of gearing can only be used for reduction, its not like a normal gear set that if you input power on the output side and he input turns with an inverse of the gear ratio.
Question? If in a gear reduction aparatus the slow turning end gear is turned very slowly, will this spin the initial gear super fast? Please demonstrate!!
What will happen if we driwe it backward?
willl it rotate?
1.073.741.824 easy one, just 32^6.
Math
I followed (32^2)^3. Funny how powers add, isn't it? :-p
technically powers to a power multiply but shmeh
The exact gearing ratio should be approximately 1,073,741,824 if I'm not mistaken
(32^2)^3
+Derrick Jolicoeur An approximation of an exact number is a contradiction in terms.
where i can buy one of those things? 1bil:1 reduction? again can it be used backwards? instead of reduction to amplify?
I feel like I should get one of these and make a video of me turning it all the way around once LOL.
The gear ratio is exactly 1073741824 to one.
Is there a limit to the gear ratio that passes the point of no return for it to be a two way system?
With 5 revolutions/second, it would take *6 years* of continuous turning to turn the outer wheel 1 full rotation.
so 1 rev per second is 30 years?
@OskarPuzzle can you make a box to go the other way? 1 to 1 billion gearing...
Happy birthday from USA!
the gearing ratio is 1073741824 to 1
If the reduction per ring gear set is 1:32, why do think the ratio is squared? Three compounding rings of 1:32 should produce about 1:32,768. This should be easy enough to physically check.
how can i get ahold of the 3d print files to this?
can you change the design so it would work in reverse like you turn one side 1 and other side turns 1 billion times. and if so how difficult would it be to turn with no load
Is there a limit to how large this ratio can become? Is it feasible to add another mechanism that makes it roughly one trillion to one?
Very cool! What 3D printer do you use? it's a stock one? That looks extremely precise
this could be ususful for some astronomical devices since you could easily make a version that takes one year to complete one rotation
the approximation of 1000 was 32^2 so I can assume if you did "1000:1" 3 times the ratio should be 1073741824:1
Can you make a video of the opposite effect. Like extreme addition
1073741824:1 there you go oskar
So, if TrackpadProductions (another commenter) is right, this has a gearing ratio of 1 to 1074741824. That means that if you spun that first gear once per second constantly, then it would take approximately 34.5 years for the red gear to rotate once. Holy shit.
whoever keeps asking him to turn it from the last gear must realize that he would need incredible hulk strength to do so and would break it in the process. not to mention that even if it were made of a space age frictionless material strong enough to withstand that power, if he could spin the hard side at 1 rpm, the first gear with the handle would be moving faster than the speed of light.
is the exact gearing ratio 1,073,741,824:1?
I don't get what gearing reduction is and why the ratio is so interesting? Can someone please explain.
What would this be applied to? This is like mind boggling how compact this is
Is it possible to turn the "reduced" side and get a lot of revolutions on the other side? i know its probably impossible, or very hard in practice, but could you explain how a situation like this might work?
There exists an equation in gearing theory that calculates whether a gear is backward turnable or not, see www.amazon.com/Kinematic-Geometry-Gearing-David-Dooner/dp/1119950945. This design definitely is not backward turnable.
