I would recommend using bearings on each wheel and decrease significantly the gaps between the different gears (Use teflon rings)
Exactly what I was thinking, I was really thinking it would significantly decrease friction.
Journal bearings would be best
I'm guessing that adding a lubricant like oil would also decrease friction? Maybe transmission fluid idk?
Also add a chanfer on the bed side of the print. You can se the first gold gear to have a big elephant foot (Layers squished at the bottom) and maybe add grease
Teflon or brass washers would be good to pack them more thingly and reduce vibration
Also this type of gears are really dangerous at high speed. Never be over the axis of rotation. If you reach really high speed inside your house you can get your ceiling damaged, electrodomestics and pets
Agreed
Some suggestions:
1. use spacers on the axle, so the gears are fixed on there to prevent wobbling and gears grinding against each other
2. use a normal M8 steel bolt instead of the aluminum rod and screw it far enough in, so you dont get vibrations in the gears. That way, the gears wont come loose as well
3. use ball bearings on the housing AND the gears
4. reduce the contact area of the higher gears. So 1st gear has the most contact area and so on
5. lube the gears and bearings
6. print the grip sideways. so it doeant brake (obvsly)
7 maybe try different gear geometries. there a some that are better for high torque or high speed. the latter have much less drag.
8. you can safe an enourmous amount of weight on the last gears. make them much thinner then they are now
Nice suggestions 👍
Can’t put ball bearings on the gears that’s not how gears work. (At least the input gear thinking about it now ig all the other ones could)
Bro have write his school essay
@@gumby5068 he’s saying put the ball bearings where the gears are connecting to the axel. That way, the gears have less friction trying to spin. Like how skateboard wheels are connected to the trucks, they have ball bearings to decrease friction
@@gumby5068 note that most of the gears are freely rotating on their shafts. Only the first gear is keyed to the shaft.
Ever heard of...spacers ? They, when lubricated, can make a more stable machine and make it easier to turn.
Yes, I was waiting for someone to say that.
YEAH
Bro, why do you sound like your trying to be rude? You just are saying it in a rude manner.
@@Parking_cars_is_coolbecause he kinda is! It’s obvious to use them so it’s surprising he didnt
6:34 That sounded more like a giant diesel engine just starting and revving to warm up.
Ikr lmao
Agreed
Ya
Yup
Gearbox in a trans
2:39 Love the physics-ignoring transition
He did a quantum tunnel
Lol
Not to mention the fact that the final gear spins faster than this guy is spinning the lever.
This guy somehow made energy out of nowhere; this violates the first law of thermodynamics.
Tbh, lets exploit this glitch to create free energy
@@Zextranet Akschully, he's expending as much energy turning the crank as you could collect with a perfectly efficient thermal generator
Yes
Sounds like straight cut gears ⚙️ they were spinning FAST!
Yea they realy do
thats because they are straight cut gears
I was not ready for, but appreciated, the ASMR @ 5:11
I like it when it spins fast
That's the best part
5:12 Now That is ASMR
I'm surprised that the last gear held together at that speed. Most of my prints seem to break as soon as hit with even moderate violence.
Skill issu- you know what? Sleep tight don't let the bed bugs bite, gn bro
How many hours you need until you finished your project
I've just watched for the first time. The first thing that came to mind was, "Wow, he could make a wonderful siren!" I sure would love to have you take me up on my suggestion. Not sure how your neighbors will feel about it though 🤯
I'd love to have a fan blade connected at the end. Would make an excellent hand cranked fan
What about razor blades to cut cucumbers
@@theegod9649 sounds like something from a saw film
@@Edwardify exactly
@@theegod9649 wouldn't work, the gear spins fast but it should stop with incredibly little force
I've had a curiosity for a long time: how to extract energy from something that's very heavy, but moving very slowly. I present the challenge to you: how much energy can you extract from a falling weight? Or, how long can you keep a system moving, while only dropping a weight a short distance? Ultimately, the scenario that fascinates me most is glaciers. It would seem there's a very large amount of potential energy there.
Wait until the glaciers melt and build a hydroelectric generator/dam
@@SjaakWWortel haha
While you are there, wait for the tundra to melt, now you increased the arable land 4000% near the artic.
You also get more wind power as a side effect, perhaps even too much of it, as more energy is freed into the system, a couple of tornadoes here and there, not big of a deal.
And your coastal lines might change by a couple of meters. That's a minor deal thou, who would build anything on beaches anyway. Lots of erosion already.
To your first inquiry, I present to you, the mechanical battery….
4:00 Definitely one of those "measures twice" moments
Have you done a cycloidal drive gearbox? I've seen them do over 20:1 in a single stage.
Can't wait to see the next iteration, I want this baby to be clocking at near light speed when you are done with this
This is awesome, i love gears and their mechanics so much that i even thought of making a GOOGOL spin with some fictional/indestructible materials and a huge engine, with a big fan on the fastest gear
Well you should check out videos of Lego's, with lots and lots of gears.
you can add a worm gear for rotating the slowest or the main driver gear as it needs more force to rotate other gears
i've heard that 3d printer worm gears are terribad. but again, i have no clue about what i'm talking about so..
@@JoachimVampire he can add small metal worm gear , actually my perspective is , as worm gears have to much load capacity ans speeed reduction we have to give less force with hand so there will be less chance of breaking of gears
Handy little trick I’ve learned working with Gears and Gear cases. Take the end of your sandpaper and tape it to a drill bit. Wrap the sandpaper around the drillbit and now you have a rotary sanding tool.
that 3D printing ASMR tho when taking the handle off the bed
I really enjoy it and laugh at the same especially during the breakage, oh boy you don’t have any idea how envy I am for such skill you have, keep doing more video, I’m your subscriber now.
I recommend using a impact drill or 3d print an adapter to hook the gear box to your lugs on your car for max power
Did you seriously just suggest to make plastic battery cable clamps?
#6:30 bus engine sound (also please add a bearing or maybe lubricant oil or a transmission fluid for better results).
Wow. This guy's patience knows no bounds. My patience knows almost no existence.
Sounded like the school bus, brought back some good memories
Young man, there are people who frequent the salt flats trying to break the land speed record who would greatly benefit and appreciate a team member like yourself.
Why?
@@mike3667 why??
Why is the sky blue? Why does the 3:92 posi-track on a 68 Hemi Cuda work?
*It just does*
😁
Why not try helical or herringbone gears, they would have a more consistent transfer of power. Also what did you use to lubricate them? With the high speeds of the last few gears the lubricant may just get flung off.
You'd need 2, one in the opposite direction because of the angle is also trying to move it sideways
@@prich0382 That's what a herringbone gear is.
As you gain momentum shift into the next one like a manual transmission.
6:33 straight-piped G36 at 4am:
Besides the actual gearbox being made, I'm interested in knowing how much all the machinery and tools used cost as well as the cost of materials and electricity, for just this one gearbox.
Also, does that 3d printer allow for different levels of hardness or flexibility with the shapes it prints?
God, I love watching things go fast.
Watch your sex tape then
Great video. One tip, get some cutting oil and use it when drilling metal. You'll spin the drill slower but it will cut faster and cooler. When it's cooler it'll wear your bits less and cut the metal smoother.
If you get it and don't agree I will pay you the $10 for the oil. No joke.
0:18
That is a very pleasing sound
look into the gearboxes used for hand-cranked sirens
Certain components imo are just simply made easier and faster out of different materials, for example: the handle and base can be made from wood with handtools. Also after initial prototyping, gears can be made from by the aid of fixtures and woodworking jigs. See Mattias Wandel's channel.
making the handle and base from hand tools would take hours for someone who most likely doesn't know how + gears can be made out of other materials in 3d printing and it is most likely quicker to 3d print
Omg, the sword at the end was a welcome surprise 😂
7:58: That's no sword... It's a space station.
@@Pseudothink It's too big to be a space station
You are just like me, whenever i do any work after doing all the work i remember i missed a small thing or made a small mistake because of which i have to do all the work again.
5:51 sounds like a primary school school bus engine noise from hong kong
Have you tried attaching a load to one side, and a generator to the other, for example, so that the load drops in 24 hours providing electricity? make a semblance of a gravitational power plant?
This man took overdrive to a whole other level
I think u should use ball bearings and herringbone gears.
When the gear box spins so fast that it sounds like a PS4 cooling down
Well done bro you should be really proud of yourself
you need bearings and solid gears, your spoked gears are causing significant air resistance
So.
Enough gear ratio that a dropped weight of a few tonnes, pulling a chain, will cause a serious amount of power generated (think power plant), and when at the bottom - disconnect gears while pulling the weight back up, re-clutch the gears, and let gravity power the power plant once more.
Do this with enough gears and you literally have perpetual motion.
In the early 1980's a New Zealander was watching a coin spinning on its edge but face down until it eventually fell flat and stopped. He consulted a mathematician and an engineer who together designed a reduction gearbox that had enough torque to dislodge a house from its foundation. Are you familiar with it? because as like "Epilogics" infinitely variable transmission that supposedly could handle large torque loadings both seem to have disappeared.
Use cutting oil and low RPMs with a lot of pressure while drilling metal.
1:45 smaller holes are easier to fix, because I can precisesly drill them out :skullemoji::skullemoji::skullemoji:
💀
It might use more PLA/ABS but if you print the parts at a 45° angle against the bed they become much stronger!
Emagine this being a gear box in a car lol that would go SOOO FAST XD
Yea lol , but you would need a VERY big engine .
you should make a wimhurst with your 3d prints and see how fast you make the energy spark ? i think if you use the gears it will make the energy higher .
Friction drive would of course add friction but reduce the need for tolerance . Maybe be worth a try.
I would love to see a tuktuk peddle powered with 3d printed gears, that also transfers the energy to a battery! 🤔
Would not result in anything extraordinary or unpresidented. The laws of physics will not be broken or mocked.
you should try with the 3d printing material that has metal powder in it and you put it in a furnace and it turns solid metal to make some crazy fast ones that dont break
Youve basically achieved the same engineering capacity as spinlaunch without spending millions
It’s so satisfying
Using a hand drill on a drill press, classic
This whole thing sounds almost exactly like a diesel truck
if this dude built a house and it failed he would instantly start making it stronger and building it again
6:30 more like a V6 engine revving to the Red Line!
Some bearings and some spacers could make a significant difference in friction
did you know?
if you added 999 grear, you can get speed faster than light just for one rotation on other side
The main reason you can't get it any faster is friction between the gears and the shafts. This is exacerbated by oscillations caused by the very low tolerances you're maintaining to keep everything moving. The frictional torque especially in the faster moving gears is amplified by the gear ratio, which makes it very hard to rotate the slower moving gears at a decent speed. If you use cheap steal bearings, you won't have nearly as much friction and you you'll be able to keep tolerances high, leading to less parasitic oscillations. Keep making :)
Fuck it, needle rollers.
This looks really cool,. what was the material used to print this?

His Neighbours be like: OI SHUT UP MATE OUR EARS BURN
Probably save some frustration by getting a screwdriver bit extension.
Crimony time is going by fast as I grow older , I saw the dat e Aug 10 on the video and thought it was from last year and took me a few seconds to realize that it is not only not July anymore it is not even August .
My small brain couldn’t handle what happened at 2:39 i had to keep re-checking it
bro i swear ur channel will blow up soon!!
ma man is studying gears 💀
you should really consider using spacers between your gears so they're not so wobbly and all over the place!
Imagine adding a little generator at the end
Easily one of the most interesting and satisfying videos I've seen.
Now I'm really interested in gears, and mechanical interactions.
Where would I go to gain a greater understanding of the principals at work
here? Please don't bother suggesting any college courses, I have neither the time
nor money for that. I'm only interested in the knowledge, not the degree.
Oh, and thank you for this. Awesome work!
Buy a Machinery's Handbook and read the gear section, no better learning than on there
Use a berring on the handle so it has less friction on the hand
6:52 Geographer: Sky Skating
Was also used in one of @Drawinghands videos
At least let her know you used it as well bud!
Basically Truck/Bus sound generator.
Idk why but the the gearbox is so amazing
Needs bearings and the gears need to be properly shimmed so they can’t wobble around
Have you tried printing on PEI sheets yet? It's a genuine life changer. No need to use glue, spatulas, or brims on your prints anymore.
Dude, you had plenty of rod length-I would think a 10mm spacer would have been easier than remounting the whole device. Great work, though!
Very odd to watch this. I'm amazed it even sort of works. Just for reference, your final gear speed is roughly the speed a chain saw chain runs over the nose of the bar. No gears at all, drives directly from the crank shaft. You really seem in need of a copy of Machinery's Handbook (Industrial Press).
Imagine if this was on a bicycle!😮
AND ALSO FOR 3D PRINTER PRECISION, YOU CAN USE MAGNETIC LEVITATING RAIL AND MAGNETIC GEARBOX, THIS WILL MAKE SMOOTHEST + FASTEST 3D PLASTIC PRINT ON THIS WORLD.
I noticed you had a tub with EXPLOSIVES on it. what is that for?
I'm guessing explosives.
Mayeb for the handle use a breaker bar and try to connect that
2:39 magicccc😱😱😱😱😱😱
Why are they always limited to a crank to generate energy? what happened to the spring-loaded toys?
Honestly, I'm just waiting for someone to go super sonic with gear ratios.
Sounds like a state transport bus
Like my Evil Knievel motorcycle. We took off the handle and put an electric drill in its place. Burned off the back tire .
if you made the last gear 'full' instead of 'hollow' the moment would be smaller and you might be able to spin it faster
What?
More mass = more inertia = more moment = harder to spin.
How about making input a gearbox like in a car, so you don't need to apply a lot of force to start that thing and change ratio gradually.
What are you using to help adhesion to the plate??
What settings did you use to get such a high quality print??
Yes I agree, I have to use a raft every time!
could use this to make a fan
3D printers are like the gateway for people with absolutely no mechanical knowledge to build something.
I'm not even a minute in and I predict it will fly apart, something will fly apart. SOMETHING!!!
Bro it's been 2years your are doing this and you don't leanr from errors, like seriously...
Great video
I keep finding greater and greater nerds on RUclips. I think the algorithm has me pegged... 😂
