What happens if the gear ratio 30,517,578,125 : 1 is turned with a drill?
30,517,578,125:1 Gear Reduction! 3D printed gears
In this project I made a little Googol reduction with 3d printed gears.
•The modules of the gears I use in the project are 1 mm. Pinion gear 12 teeth, corresponding large gear 61 teeth. The gear ratio in each stage is 5 and there are 15 stages in total. Total gear ratio is 5^15 so 30, 517,578,125:1. That's really a huge ratio. The drill I used in the video is 550 rpm and this drill works 106 years for the last gear to start rotating.
•The bearings have 608zz and 8mm inner diameter.
•I used PLA + as a material and set the nozzle temperature 205 degrees and the plate temperature 40 degrees. I used Simplify3d software as slicer.

"The gear will turn 106 years later." Damn, that won't be in my lifetime.
The plastic would wear down loooong before then so even if you did live that long it would never happen
@@ArnoldSchwarz_enigger Exactly!
when I hear this song all I can think about is "SCP-673 is a Keter Class SCP"
I was wondering why that sounded so familiar
Always fun to see other peoples designs! Nice bearing holders!
I learn something new every time I watch one of your videos. Cool gears.
00:55 A wheel with 61 tooth and pinion with 12 tooth has a ratio of 5.0833333... instead of just 5, this trivial difference of 1,66667% in a single gear reach a difference of 28.1382% in 15 gears. So the total ratio with 15 gear is 39.104.688.834 and not just 30.517.578.125 (1.281382 = 1.0166666^15 where 1.016666 = 5.083333/5 = 61/60).
It would be more interesting to turn the counter side ;-)
It would break
@Bentley Johnson there is by far enough
thats not how it works.
@Jose Mejia Perez something more reasonable in a ratio.
@Jose Mejia Perez depends on how strong yo make it
I warched a lot of these video’s and you are the first to show how many tooth the wheels have. Very nice
lol @ the inquisitive music when the machine starts running!
Man I can't wait to get my printer. Gonna make a new lighter mouse shell. Nick nacks like this and tons of figurines
Just wait till you have to do maintence on it or start having problems thats when youll start regreting it
That's awesome, dude!
Thanks dude!
If you dont understand just Googol it!
Agree 👍
I once saw a setup like this in an art gallery where the final gear was set in concrete.
Cool project! Cool soundtrack!)
:) Thanks my friend
imagine the torque that last gear would be capable of. you could use this to move mountains
Input torque = output torque You'll need mountain on first side to move mountain from ther side
@@rrrr3666 I know this was 9 months ago, but that's utter BS. A quick Google search will tell you that a gear system can either increase the torque or the speed of the input. That's literally the purpose of gearboxes. They act like levers do, and, as we all know, increased leverage = increased force / reduced effort.
Can you block the end to act as a soft and long torsion bar?
Can you explain the math behind how this works? I’ve read that such a machine cannot be operated from the other side because there’s not enough energy or something like that. I mean, if you COULD force the last gear to spin, would the first gear go out of control? I’m trying to understand how this works!
Great vid 👍🏻
cool vid. please shoot more slow mo and some time lapse of the reduction running for a some hours. or days.
Hey man this was a great design and a really fun print to get my Christmas Prusa up and running correctly. I uploaded mine to the makes page on thingiverse. Thanks for sharing!
Looks wonderful dude! You're welcome, glad to see this!
There's a similar set up in the MIT museum, but the end of the gear is bolted onto a concrete wall while the motor keeps turning non stop, all day
How many gears or gear ratios could spin from the other end before it blew up?
Wish I had a 3D printer. Those turned out great
Thank you my friend, your music also great👍
You can pick them up pretty inexpensive! Check out the Ender 3 under $200 and really reliable, I've been running 2 of them for almost 2 years with very little trouble.
3D printers are great, just don't buy a Velleman. A velleman printer is a great printer to have in your electronics class so that you can teach your students how to fix 3D printers. I bought a Prusa Mini. It has a better print quality than the Vertex Nano from Velleman and a much bigger print volume.
wow 😮👍❤👏🤩thank you
Nice upload. Have a nice day.
Hello my friend ❤️ Beautiful. Very very good 👍. Big like you 👍❣️🤝
What program did you use at the beginning of the video when you set the gears in motion?
I can't wait to see it turn. 😁
😁😁
Can we get a progress update?
now thats a good pulling tractor transmission...
I'll be back in 106 years, see ya guys
You could live stream it running for years !
It wolud be great👍thanks for stopping by👋
god imagine, you could watch until the collapse of the earth
Disappointed that this video is only 2 minutes long. Should be 106 years long, minimum.
Why the car battery drill setup? Why not just a rechargeable or wired drill?
Cool!
Does it make much difference if the gears interact in a longitudinal way? Means instead of stuffing them together they can be placed in a single line for the same work
I think yes. Because each gear turns different speed and the gears touching them together. you can easily get it from that video: kzhead.info/sun/oL6hc8qIm2WFdZE/bejne.html The friction eats power
am i the only one who hates it when i see a huge gear ratio but then they spin it from the wrong side?
Why not turn from the other side? I wanna see other side turn at least once
Hello my fried. very nice. thank you so much. be happy. bravo. see you..
Hi my friend, thank you for dropping by. See you👋👍
@@retsetman9698 👋👍
This is actually a 39,104,688,834:1 gear reduction, not 30,517,578,125:1, assuming the tooth count you gave in the video is correct! (61/12)^15 = 39,104,688,834
Smort
100 years later, I guess I my grandpa was wrong.
why do i keep watching these
I know that to turn this from the other side is not possible. So what is the largest gear reduction that we can turn from the other side?
Actually, i have plan for that. I will use 775 motor and add the gears respectively
@@retsetman9698 Thanks
I need the gear ratio and shaft size and also teeth size 😢😢 please
I'm watching this and all I'm thinking is TheRubber
Petition to attach the drill to the other side.
So can you turn it from the other side
I wanna see someone bolt one of these to a rock solid bench, get a huge lever and try to spin the last gear. We could probably hit light speed that way.
nope, that would not work
Here I was thinking you’d’ve spun it the other way to watch the full force of the 30 billion scale up
For the next project I'm trying to rotate it on the other side for the maximum possible gear ratio
Now I just want a door of eternity being lifted by stone gears spun by a water wheel that only works during the wet season made by a ancient civilization using this gear ratio. Eons pass and the door is but a few inches off the ground.
Shouldnt it take something over 3 years for the last whell to spin? If it goes at 20,000 rpm it wilp take it 1,525,878 mins which is 25,431hrs which is 1059 days which is 2.9 years
What's the appeal in building this sort of thing?
What software did you use to model those parts?
I used fusion 360
I have never understood this i always thought that if a gear is connected it would automatically spin the next one and that one would spin the next and the next how does it faze through the next gear and require power to push the next when its already connected should it not just spin them all at once wouldn't it just require force
It's because if you look closely, each cog actually has two gears-the big one, and a smaller one next to it that drive's the next cog's big gear. If the ratio of the two sizes is 5:1, then the first gear has to turn five times to turn the second one once. And that has to turn 5 times to turn the 3rd one once, and so on.
Legendary🏆
Thank you Mr.Hasan 👍
Bạn rất khéo tay 👍😁🇻🇳 Video rất tuyệt vời 👍 Chúc bạn thành công 👍
This kinda reminds of how time works!
The video ends before the gears hang up ~ they were turning until the "slop" between them was gone.
Ya good point. There is 14 mesh pair sets (no .. is 15) and reduction is 5.08:1 per gear set. If angular backlash per mesh set is 1° (reasonable guess considering it's non machined nature and visible slop), it would take 4,125,524 revolutions of the input shaft to take up all of the drive train lash. Put another way ... it would take 412 minutes at an input of 10,000 rpm to take up all the lash Edit: Keep finding errors in my calcs .. the above is wrong. It should be cumulative. Final is 264,046,306 revolutions of the input shaft or 26,404 minutes (440 hours) at an input of 10,000 rpm to take up all drive train lash
Clock movement for measuring in centuries
What cad software was that at the beginning?
Fusion360
@@retsetman9698 thank you
Which software do you use for desinging
I used fusion360
which software did you use?? plz !!
Fusion 360
I will come back 106 years later.
Hopefully:)
Suppose the last gear turned at 100 RPM, how fast would gear #1 turn?
I tried that but looks impossible. This video can gives an idea: kzhead.info/sun/oL6hc8qIm2WFdZE/bejne.html
Other side pls
Wait what if we turn the other side
I want to put this in my scooter with reverse so that i can keep up with turbobusa
It´s 5 to the power of 15 or 5x5x5x5x5x5x5x5x5x5x5x5x5x5x5 (15 times) .
other side pls
lk9 fw awesome superb video adorable work big thumbs up from me thanks for sharing stay blessed with good health & great happiness/safety take care have a nice day ahead thanks
Thanks friend
Can you try this ratio 1 : 1.8×10^¹⁰ just opposite of this experiment.....
That's life, the slowest gear is life, we live once our life spins once.. The other gears are years, months, weeks, days, hours, minutes, seconds, etc...
put an generator at the input spin side and put a big weight at something in the other side and boom free energy for more than 5 years
Now put the power in from the other side. Making the other wheel turn 30billion times per second and create time machine.
By the time this shit turns i am going to be 130 🤣
Please, post a video with a drive this assembly from another gear side (1 to 30 millions)
If you were to spin it from the other side it would move faster then the speed of Light. Also it would be imposible to move it tho
@@felixmedparkour3259 A requency of visible light is between 4 and 8 * 10^14 but in this case we need only 3 * 10^6 Hz.
Very good kartezyen atolye
Thank you bro
@@retsetman9698 You're welcome Mehmet bro
Dis frame and da weak shafts can't just take the torque u'll get with a tiny dc motor
He starting to believe
It would take probably 3 years just to take up all the lash.
Which program is this? 0:10
Fusion 360
How much torque do you need? Yes.
😅
wait a... if in the real world its impossible to turn it from the other side because friction of and thermodynamics... what would happen on a CAD assembly?
I was very curious about that too. There is a problem in the first few stages. gradually the fan sounds increased and the program did not respond:D
Vbx or vxb bearings are like 9.99 for 100, guess who bought a shit load of bearings!
Now hook it up to the other end
But what happened if i would turn this, from another side??? Mystic....
Check out the channel
Videoları çok kısa yapıyorsun. Sahneleri hızlandırmadan yapsan daha iyi olur.👍
gravity generator !!
But why?
Does it have enough power to spin that last gear? I think things will break before that last one can turn, too much friction.
Maybe 1:3bilion?
man but I wanted to seeeeeeeeeee
Now turn the other side
Ok why this mathine what is their purpose?
Can you add stl files pls
Added in description
فيديو رائع
Thanks brother
Other sideee plssss
Seriously? Is that all you got? 30,517,578,125:1? Let me know if you get to a trillion.
why do u use the music of scp vids
Turn it from the other side
Nothing like this happened
