It would be interesting having a clutch mechanism to separate the power output and isolated from the engine.
I was about to say the exact same thing, I got my friends son a build your own model of a 4 stroke engine a few years ago and helped him build it, I had a fair idea of how everything mesh's together but seeing it up close relly brings it home.
He could've also made it a 5th gear transmission 😭
That would only really be more helpful with a flywheel and running this at a higher speed
He can simply turn off the power being that this is run by an electric motor, the clutch simply disconnects the motor from the transmission.
@@x2e4 my car says thank you
That's pretty cool. This would be representative of a very compact transmission like might be found in a motorcycle or early FWD car. A typical rear drive manual transmission has the input and output shafts on the same axis, with the power being sent down to a countershaft to select the ratios. The lowest reduction is usually at the rear of the case, as it puts a huge load on the shafts trying to push apart rather than rotate. You'll have first, second, third, and sometimes fourth as reduction gears, with the next gear being a direct connection between the input and output shafts. After this, you have overdrive gears, where the output spins faster than the input. This is usually in a second section of the transmission, behind an intermediate bearing plate as now pushing forces are getting higher again.
You seem knowledgeable about this, mind making a video explaining this?
That actually sound like a typical FWD gearbox, except for the 3 shaft design) - 4th gear is closest to the differential, moving away towards 1st, then behind a bearing plate is 5th and 6th (sometimes with additional bearing plate at the end of the shafts)
And reverse doesn't use a collar lol
My favorite printed gearbox is the sequential 7 speed w reverse. Don't remember the designer but he did an excellent job. Its a good design as you can scale it with realitive ease depending on your application. When printed with nylon it is strong enough to stick into an rc car. All I have tried so far is an electric motor however I think it can handle nitro as long as it isnt too small.
That would be the F1 gearbox?
got a link for that ? would love to print one as educational tool

There are a few hours worth of content on this channel
I would love to see it as well
Even in weaker plastics, gearboxes like these can be surprisingly durable. Someone tested printed worm drive gears with and without grease and as long as they had grease, they could 8,000 rpm for a while with no visible wear. The actual numbers might have been higher but I haven't seen it in a while
Amazing! If I had to suggest an improvement, the color coding could be improved. Everything perpetually connected to the driveshaft should stay blue, but everything connected to the output shaft should be red, so we can see better what's connected to what. The rings could be their own color like purple or something
This is so beautifully explained and demonstrated. What a great video!
Thank you so much for the dedication to your videos and the quality of your videos. I enjoy them every time and i think you have some of the best quality descriptions in this sort of content area
I love how this video showed how simple a concept this is! So many other videos make it way more complicated
RUclips is recommending this to me when i started working on my own 3D model of a manual transmision in cad which is scary and useful and btw you’re videos are awsome its a shame you dont get the support that you deserve
Microsoft is selling your date. All these tech giants are one and the same at this point.
One of the best basic explanations I've ever seen. Simple and direct with great visuals. I agree with some of the other comments about the clutch mechanism but I understand that would be best done in a follow up video. Keep up the good work!
Such a great video with a fantastic explanation, well done.
Do you have this transmission available for download ?
I think that it will be a great project for kids to learn how a transmission works in conjunction with your video and explanation.
Keep up the great work
That explains this really well. Would be interesting if you expanded and added a clutch disconnect too. Just to see the extra level that adds.
The clutch is not needed to shift but it’s cool too see.
Something I don’t know now is how the synchronizer works.
The red parts that slide are called a sleeves (there are 2) and the blue parts they engage with are called dog teeth (each gear has its own set of dog teeth). A synchro ring is attached to the front of the dog teeth, it can spin but if pushed towards the dog teeth it will grip. So when the sleeve is pushed, it initially hits the synchro ring and engages with it, at the same time the synchro ring grips and in turn spins the output shaft faster or slower to match the required speed. Once the speeds are matched (synchronised) then the sleeve can slide fully onto the dog teeth.
This short video does a really good job illustrating synchronizers ruclips.net/video/0Bqs-oHBBQk/видео.html
At that point it would be easier to do a cutaway on a motorcycle transmission. Clutch basket is on the input shaft a single bearing width away from the box
Constant mesh, straight cut dog box.
Granted it has a shift drum to move the forks but it's all right there.
Genuinely one of the best demonstrations of how a manual transmission works I have seen yet. Better than those fancy 3D animations for sure.
Only thing missing is a clutch.
I love them for how simple and straightforward they are, you couldn't be more basic and direct if you tried.
Soo cool man been here since 90k but love your videos, learning more about 3d printing and physics then I thought.
Is there a link to the stl? Would love to print this myself
Agreed.
Agreed!
you can buy it from here www.enginediy.com/products/3d-printed-manual-transmission-model-physics-experiment-teaching-model-educational-toy
Awesome video! Helps a lot for a visual learner like myself, thank you for making this!!
Short, simple, amazing. Keep it up!
What a great explanation of this process. Thank you!
Thank you, amazing video
Very good info. Concise narrative and good camera work. Bravo!! Well done!
Thank you for demystifying such an ingenious mechanism
Honestly this is very helpful for learning how a manual transmission works
I’m basically building a go-kart from scratch and this is exactly what I needed to see
man, you explained it so good.
Great video. Really helps me to understand. Thank you.
Good job explaining manual transmission. Thanks for sharing your design ❤
Beautiful work bro
This is friggen godly keep it up!
Nice and clear!
Great video!
Great video. Thanks from Texas.
This is neat! Thanks for sharing
I wish I could bring this into my classroom! What an awesome visual!
ive seen a bunch of these, but this one was the best
Really cool. Thank-you!! I've always wanted to know
Linear boxes, like in motorcycle, are just as much fun. I love how the two systems both work great.
Great video and explanation
Thank you the video.
Awesome. Thanks!
I was so intrested thankyou for explaining
Great explanation! Thank youi
Excellent explanation!
wow always wondered how they work nice vid
Really well done.
this video's on par with the old black and white demonstration video's from the 30's and 40's, nicely done.
Excellent model, waiting for stl :)
Best explanation I've ever seen.
i love the 3d printed model of it that's awesome well done ♥
Man you are a real 3d printer I mean look at bro... That looks really awesome bro well made 👍
Super videos ! 👍
I love how you simplified a very complex engineering problem into something dummies like me can understand. very good and educational video!
This is such a complicated way of explaining manual trasmission!
Wow this is very very very good
Hello,
I love the video but it would have been even better if you explained how the red circle transmits the mechanics power from the driveline to the ouptut.
Have a great day :)
If you closely at the output gear, it is connected to the middle gear, I suppose that by moving the red bit, he is making it so that the gears get linked, by making the red bit touch two gears.
So Cool. I Iove this.
Super interesting 👍
I've been to a lot of these "How manual gearbox works" videos, and I understand how they work, but what I never understood is how the parts are assembled and how that relates to how it works
It is Simply amazing
Curious how many people watching this have ever actually driven a car with a *true* manual transmission, one with no computer involvement whatsoever. I learned on a '74 Toyota Corolla, with manual *everything*. Its clutch was incredibly unforgiving. If you were off in your timing by just a little tiny bit, the whole jalopy would start to seize, jerking the car forward and backward violently until the engine died. I have to say that learning on that beast made every other car, stick or not, I drove after that an utterly trivial undertaking!
Almost all cars (and every single van/truck) outside of North America have manual transmission. EVs are gearless. I think that the reason that the American drivers prefer automatic transmissions is ultimately due to cheaper energy costs in the US.
All the best.
Amazing video and super simple to follow allong! Is there a way to get the files for it? Id love to print one out myself
Man, that's some skill, shifting without the clutch 🥶
Excellent video! I would love to see how an automatic transmission works if you haven't already done that.
Very cool.
That's a cool model
"We have to shift gears to keep the RPM at a reasonable level."
*laughs in rotary*
Teaching me more than my engineering professors
This is awesome
very cool
Thanks for such a cool demonstration. It has always been a huge curiosity of mine, how gears are being shifted in a moving car...
I would love too see you push it to the limits. I think it would be pretty cool to see how much load and RPM such 3D printed gearbox can handle. (and yes I will subscribe with notifications too see if you actually do it) :).
A common trend in transmissions, these days, is a double-clutch multi-shaft transmission (sometimes known as a DSG). Would love to see a 3D-printed version of one of these.
smash
Ngl i really want that manual gearbox demonstration
This is nice Work there!
I Hope You Can Upload the 3d files so I can recreate your transmission!
wow perfect rev match.
This direct connection between the wheels (via the output shaft) and the engine is why you can start a car with a manual transmission by pushing it (or as it starts to roll down a hill) and then popping the clutch (esp. in 1st or Rev) and then quickly pushing the clutch back in before it stalls again. I used to do this just for the heck of it in my driveway because it wasn't completely flat - I'd pop the clutch in reverse... never wore out my clutch either.
This dramatically clarified how a transmission works to my chimp brain... thanks for the video!
The people that come up with with stuff are something else
Thats a cool little model. You should release the stl files so we can print one. I'd love to have this on my desk.
Super Cool!
Great job you are genius 👍🌷🌹🌹💐💐
Thats a fantastic little model! Is there a link to the stl files so people can make their own?
I think what he has in the video is really cool, if this gets a response that would be amazing, I’d love to build that.
I always try to teach new manual drivers by essentially describing a very simple version of this concept, so they can have better mechanical sympathy when learning to shift properly.
i felt like watching a commercial but actually learned something
Wow thank you so much! So all the gears are always meshed together! The shift only connects one of the pairs to the output.
It took this video for me to realize that the un connected gears were still spinning, just minding their own business at their own speed around the shaft. It’s an amazing design.
I’d love to have that toy at home. Is it selling anywhere?
The 3rd gear also represents an overdrive ratio. The output shaft turns faster than the input.
nice demonstration
now please do the same for automatic transmission
The text on the side of the model: "Do not put your fingers in the gears"
3D Printer Academy: *Puts fingers in the gears*
🤣
btw great content, thanks!
I would've loved to have this as a toy growing up.
Feels good driving manual
Whats blowing my mind is the speeds of the output shaft. When I rebuilt my transmission 1st was the fastest and 4th was the slowest. So it's odd seeing it differently, but this could be the correct way.
great video but i was laughing when i read "do not put fingers in gears" and then you said "look what happens when i put my fingers in the gears"
I clicked on this video interested in this 3D printed mechanism and just learned how to drive a manual
Not long ago, someone broke into my car and was in the process of hot-wiring it when they inexplicably abandoned the attempt. Some have suggested to me that it was because they suddenly realised I had a manual transmission and gave up because they didn't know how to drive manual.
Another reason to own a manual drove vehicle!
Not in Europe
The drive shaft connected to a small gear, the small gear connected to another small gear, another small gear connected to a large gear, the large gear connected to the output shaft. Doin the transmission dance.
Those like me who are still confused, check out Spinning Levers - How A Transmission Works (1936). Had to watch that video after this to understand lol
That IS how a manual transmission works. Some will just have more gears but the concept is the same, more gears and red connectors will mean a bigger range of control, like 5 or 7 speed. Add a clutch and you can switch gears faster. The clutch also allows you to have the engine running while the car is not moving.
Thank you for the interesting video, where can I find this model?
Awesome explanation, thanks, but I don't understand how does the red piece work - how is it connected to the shaft?
Same question here. I assume it locks the output gear to the shaft somehow, otherwise the output gear is freely rotating.
@@LKRaider It's the red piece that's connecting the gears. Initially, the red piece is connected to the shaft, then it touches the moving gear and the shaft gear.
I still don't understeand how that works but it is a cool video
That’s so cool! What was the print time?
There are a lot of cool things about them... Im in the small group of 15% of Americans that can drive one thats cool.. I can control my rpms and tell my wheels to either spin or get the best possible acceleration out of my vehicle without tirespin... Thats cool... If you blow a manual trans you can buy a $200 rebuild kit and have that thing good as new by the end of the weekend thats cool too
