I 3D Printed a Transmission: How Strong is it?
Вставка
- Опубліковано 10 лют 2023
- Today, I 3d printed a 3 speed manual transmission. The transmission was made for my 3d printed air engines and other purposes. This specific type of transmission is what's known as a 'dogbox' since it does not use any synchro meshes but rather dog gears instead. The intention of the design is to allow one to shift the transmission while under load, unlike a typical transmission. Race cars are often equipped with this type of transmission as they can handle much more power.

My new favorite comment
I cant unsee it now
@@layZlad OH GOD ME TOO
Nah.
HELP ME GORDON
I have a feeling that Camden is building a completely 3D printed Gas powered car 😂
Would love to see that ngl
Car? This dude will build a whole truck with a I6 😂
As Johnny Cash once said, I'd get it one piece at a time
Cant wait to see the cvjoints and limited slip diff for it too
@@theoverlord3839 CV joints sound like a cool idea
Shifting without a clutch really grinds my gears

@@DH-xw6jp lmaooo
This is a low speed, low power transmission. An electric drill, although torquey, isn't unloading a couple hundred horsepower and foot-pounds into each gear.
I know this may sound a bit cheesy but i think its fair to say you have become my favourite youtube channel at this point.
Love your projects, keep it up!
Thank you so much! I'm glad I can deliver good content for you to enjoy!
Keep it up bro. I swear 3D printing makes every mechanism 10x easier to understand. I hope you’ll get the gas engine to work, maybe you could put it in a RC Car or something 😂
Thank you! Glad I could help make sense of it!
I forgot about the bearing and had a long moment of confusion but know understand it I think lol
I went back and realized I skipped a large part and missed his explanation
I might be a bit late, but one substitute for the plastic bushing could be a yo-yo bearing. They're about half the size to a quarter of the size of a skateboard bearing. Not entirely sure if they can withstand a good compression as all they do is hold the string of a yo-yo. But could be worth giving a try to reduce wear and having to replace the plastic bushing as often. Awesome video though!
Never thought of that....
This is fantastic stuff! Loving this continued project of literally building a drivetrain
Great video as always! I love how your designs are not only well built but allow for a better understanding of the principles behind the mechanism. Keep up the awesome work!
Thanks alot! I'm glad I can help give a better understanding of how they work through my designs!
dude i love your videos every time i come up with a idea you have all ready done it . i hope you luck :)
respect on that seiko brother, that color dial is very nice!
Still waiting on that 3d printed Lamborghini I commissioned
That would take a long time let em do what he wants planned for the channel first lol
Your work is amazing!
Too amazing... 🤨📸
I’ve been waiting for this video. Keep it up bro.
Thank you! It means alot
Love the watch! The gearbox is pretty cool too.
Thanks! It's a seiko spirit sbtq045 if you're wondering
It is impressive. I was expecting your makeshift plastic on plastic bearings to melt together.
Love this dude. You are a genius and good explaining. Normally it doesn't happen tougher. I would like to see more the part of design sketch and 3d modeling this parts. I know you skipped that to male it friendly for everyone but can be a separate video and we all can learn a lot from that too. Keep up the good work 🥰😍
Thank you!
cool shifter and cool watch
thanks for files , i printend one for me
Cool channel! Great engineering skills.
Thank you!
such a cool idea bro but would love to see a more in depth explanation of what's going on particularly with the gear selection system and gear ratios. otherwise brilliant video my guy!
Thanks! Next time I will focus more on explaining the design and theory (without rambling on too much)
Saw the thumbnail and was like: what is edward snowden up too with a gear box!? Oh. Wrong guy. You just look like a young snowden 😁😁
I am not sure what filament material you are using, but i would suggest PETG as an alternative to PLA as it has a lower coefficient of friction to PLA and would help with keeping the tolerances tighter while keeping an easier slip fit for the clutches.
Genial ! je modélise des boites de vitesse pour des crawler RC et j'ai un projet de vélo cargo , pour lesquels ton design semble être très pertinent ! j'ai très envie d'essayer de travailler dessus pour l'adapter à mes projets ! un grand merci pour ton partage !!!! :)
3d printed money shift is something we all want to see
you beat me to thee torque convertor, I would love to see how it works bc I want to make one for my rc car
Wonderful!!! Now make one with a clutch 😃
This would be perfect for custom rc cars
Incredible videos man. Any word on finishing the gas engine?
Thank you! I am not working on the engine now as I am far too busy to, I've decided to move towards bigger and better projects instead
Never seen a 3d printed torque converter before! Looking forward to that 😁
It's a very intrepidous project (for 3d printing, at least). I'm glad you're as excited as I am!
oh shit you got it all printed
Maybe redesign the dog gears to have a 45° incline before a positive 90° lockup between gears. Maybe the friction between the gear and dog gear will allow for a smoother transition instead of a higher torque shock when shifting between gears.
Provided, such friction in motor vehicle transmissions would wear down the components much faster, but for a 3D printed model, it might make it smoother without requiring synchros.
How'd you make the shift forks and how do they mesh with the shifter?
Make a 2 cylider gas engine would be great to see If you like the idea
Hey I stumbled upon your page and I would like to follow your footsteps and print some similar themed mechanical parts, I was wondering what filament you youse for your projects and if you have any tips or tricks?
I mainly use PETG for all my filaments, when you print parts that interact with another 3d printed part you generally want a tolerance of 0.5mm. If the part interacts with a machined part like a rod, you want 0.25mm of tolerance
@@CamdenBowen Thankyou so much!!!
There is an very old video on you tube from like the 50s explaining how manual transmissions work.
CVTs are also use in tractors, but they do not use belts they rely on hydralic systems and they can handle 700hp easily, in tractors cvts are slowly becoming the standard
May I suggest duplicating the Constantinescu Torque Convertor?
You are loading the transmission with centrifugal force from the flywheel. Would of been nice to see how much torque it could output before it started to break apart. The being that the break was at the drill the test only showed that the immediate torque from the drill which can be extreme broke your input shaft.
Now you should make an automatic to match your fluid coupler. However I don’t know how you could do that remotely easily
IT BLEW THE SHAFT
You should def make a transaxle
you should make a clutch too and hook it up to a 3D printed engine!
Any way you could test that transmission and torque converter on a three or six horsepower moter? Im sure the go kart community would be pleased.
Have you thought about making a sequential gearbox? Instead of a standard H, you would just have to bump the shifter forward to upshift or bump it backwards to downshift.
I'm thinking of combing the fluid coupler with a design like that to make a sort of semi automatic transmission, similar to the experience of using a tiptronic system in some cars
The way it's supposed to go is engine flywheel clutch then transmission
Next video 3D printed differential
straight cut gears without straight cut gear noises! it'd be really funny to see you try to make a 3d printed straight cut dog box as annoyingly loud as possible
I love the gearbox whine that rally cars with straight cut gears produce, maybe I'll make a bigger one of these lol
I've been looking into finding an affordable self lubricating filament to print bearings and piston rings with. I hear nylon is decent do you know of any?
I am actually not too sure, I know that hard filaments like PLA when sanded very smooth actually have very low friction in those cases without the need for lubrication as long as they are not under high stress
I wouldn't mind seeing this in a 3d printed car with the air power engine.
I am going tomake your gearbox,what size shaft and bearings did you use?
and what are the gear ratios?
The rods are 8mm in diameter and the bearings are 608 skateboard bearings. For the gears, gear 1 is 2:1, gear 2 is 1.5:1 and gear 3 is 1:1. Hope this helps!
@@CamdenBowen Thank you!
I have finished 3d printing every thing, I just neet to get some 8mm bar(i got bearings and i am going to try some printed ones )
I plan on using your gearbox in a 3d printed rc car :)
cool!
although, i would like to see an even beter version with a few more gears
cmon' a 4th gear aint that hard to cram into the housing.
Make a small, reliable air engine (one cylinder),small shifter gearbox and differential, put it all together and make a RC car around it.
Not a bad idea, it's one I've considered a few times
Let's go
Bros been avoiding annual car inspections since 2000
Oh cool! you made a dogbox!
great vid but you need to show more of how you modeld and printed the gearbox and gears to make the video seem more complete
Thank you! I will include more theory/design principals next time
@@CamdenBowen no problem! never expected you to see my comment. have a nice day
I think you should make a whole model T or model A. You already have the engine and gearbox.
Edit: I think a Ford thunderbird would be cool too, you could make a V8 with smaller cylinders
I like the idea of replicating an old car model, Not a bad idea to do a Ford Thunderbird or a Plymouth Valiant
Stronger than most dodge truck transmissions
6:47 that’s a torque converter isn’t it? Oh dear lord he’s gonna build a 4L60 lol.
Will you be uploading stl files anywhere ?
I forgot to upload them and attach a link, I will do that when I get a chance. I should have them attached by or before tomorrow in the description
@@CamdenBowen Thank you :3
can we get the files by any chance i wanna try this
What kind of metal rods are those? Or can they be 3d printed?
Just an 8mm steel rod. I suppose you could print them however it will work much smoother using a machined rod
Bro made a Dog Box
we all know a clutch is next
Not the neutral drop 😭😭😭
I would have uses herringbone gears
I could have, but for simplicities sake I avoided it
did i see a torqye converter at the end?
Something like that :)
can you make it for a small go kart tho 🤔
Possibly from a stronger material like Aluminum at least
@@CamdenBowen probably yeah.
you should put it on a pushbike
Lubrication? Grease!
Under greater loads defiantly, but for this test its okay :)
that way of engaging gears really sucks. a differential can be used to engage gears using breaks. so the gears dont grind but thats why the clutch is used. my idea would pretty much use a different break for each gear and no clutch needed. just got to find a way to organize all the differentials in some compact way to make the breaks on the outside so there easily replaceable.
What about reverse
Definitely not complaining, but I'm just curious if the pulling of focus when transitioning to a new bench shot hurts anyone else's eyes?
Could you point out the timestamp to me?
@@CamdenBowen I can't put my finger on exactly what it is. I'm not familiar with all the photography / video terms. Something just had a weird feeling where focus and blur didn't feel natural or "usual" I suppose. Scrubbing through quickly since I'm at work, but @6:22 has that feeling...but it was several times where it just had an "off" feeling.
Sorry I can't describe it better. It could just be me also. I feel weird watching some shows that are recorded in different framerates that others think look amazing.
Great content. I'm more just curious if others got that feeling, or I'm the oddity.
@@PowerScissor Thank you! I wonder if it could be your brain tricking your eyes into thinking the objects are out of focus as if they were right in front of you and not on video? So your eyes try to grab focus on an object that is out of focus?
@@CamdenBowen Now that I'm home, I rewatched that section.
I believe I naturally look at things from close to far...in that order. 1st thing, 2nd thing, 3rd, etc. and the focus pulls from back to front.
Even when I know it's going to do that on the 6th watch, it still makes me feel weird.
You're right in that my eyes will trying to focus on a part of the frame that is actually going farther out of focus.
You put the flywheel on the wrong side of the gearbox with the air engine.
Now try making a manual transmisdion instead of a combination between sequential and manual
what watch is that? on 5:02
It's a Seiko Spirit SBTQ045, I think they're only sold in japan but I got it from a seller on Ebay
@@CamdenBowen thanks!!!
make a cvt
Put it on the VTEC😂
Someone give this man a metal printer
The things I'd do to have one...
Soooo You wouldn't download a Car!??? Moment
Subaru be like:
Most reliable Subaru transmission
the sti trans is actually pretty bulletproof, theyve been seen to handle 700whp reliably. the wrx trans sucks ass tho itll grenade at anything over 400 cause its designed super poorly with little center support
Brass gears aren't that hard to cut with a triangle file!
this thing looks like an AI generated figurine.
Now add it yo your vtec engine
why are your videos always so silent
Money shift it
fourth
Man how you do to keep the talking like that all the time? It seems like you have eaten a man Vin Diesel to be exact
Having a deep voice is cool until you have to speak all day or try and project your voice, it actually hurts sometimes lol
This guy would get more views if he didn’t drag his show on. That’s the first thing I think about and decide not to watch
not strong enough to drive a car, so, who cares?
dogbox for clutchless upshift. straight cut gears for strength. dogbox is not stronger in of itself, as all transmissions rely on dogs and houses.
Money shift it
