Mini 3Dprinted Transmission build

I Built a 3-speed gearbox for my 3D printed Engine.

[@unusualfabrication9937]

that design is incredibly clever

[@PolyProject3D]

Thank you, I'm glad you like it!

[@akkudakkupl]

It's exactly how automatic transmissions work. Ford Model T had one like this but 2 speed and manual.

[@roughedge-machineworks]

@@akkudakkupl "worked" is the word you were looking for.. they dont work like this anymore. :)

[@PolyProject3D]

​@@akkudakkupl Hello, I've just had a look at Fords model T transmission, I can see the similarities but also a lot of differences. I didn't base this design off of any specific transmission. If you have seen a transmission mechanically identical please let me know. Just to clarify, I came up with this design but I can't guarantee that someone else hasn't also come to the same design.

[@akkudakkupl]

@@PolyProject3D Not an attack at all, just wanted to give the guy something to refer to ;-) This is a nice piece of engineering.

[@prismgames]

I was laughing in disbelief at how incredibly clever this piece of design is. Well done, you are clearly very talented!

[@PolyProject3D]

Thanks you, I'm glad you like it!!

[@adrianperez3375]

Every step of this design shows a distincf mental clarity of the goals and requirements. Fantastic work.

[@PolyProject3D]

Thank you! I'm glad you like it!!

[@lilhotdog7011]

The best designs for a 3d printed gearbox I’ve seen so far. Excellent!

[@PolyProject3D]

Thanks!!

[@skylarfandrich9583]

That top bell housing bolt is the one the mechanic will "forget" to replace

[@mp6756]

I was a bit confused by the choice of materials only until I saw the lathe. At that point of the video, I saw the genius of the engine creator. The machine that built the machine has driven human progress forward until now, and the practice is on full display here. Congratulations on your designs, the elegance is no small thing. I look forward to your future 5 axis cnc project. You haven't announced the building of such a thing, but it is inevitable. Lol, great stuff, truly great!

[@Vdrumtips1]

This is amazing....until now I never understood planetary gear boxes.

[@nvcnc]

this is so ingenious! This channel needs more subs. I would love to see a heavy flywheel on the output of he gearbox so that you can do a "dyno" run through the gears. it would sound awesome

[@PolyProject3D]

Thanks!

[@thoughtbombdesign]

That's freaking awesome man. Nothing more satisfying than a press fit part right?!?!

[@PolyProject3D]

Thank you Agreed!

[@jasonAzullo]

Absolutely incredible! Super design, printing, assembly, everything!

[@JohnDoe-ej3wp]

Pretty intense number of screws on that flywheel

[@scrout]

So many satisfying clicks and snaps as it goes together perfectly..

[@PolyProject3D]

Thanks!

[@billyjoe3309]

This guy is very smart. That's all I need to say.

[@PolyProject3D]

thanks!

[@mariuspetcu2087]

Congratulations ... Stunning Work mate ... How in The World You managed to tune a 3D printer to have such Accuracy of the parts ? ... Thank You for Share with us ...

[@MaxWesterlund-yd3zt]

You should add a flywheel for some drag / acceleration sounds

[@rickfazzini22]

Amazing work! Your fit and finish is excellent as is the final result. Thanks for sharing!

[@dok.Sanger]

Для модели это очень красивый дизайн! Мягко говоря я поражён сегодня такие вещи делает один человек... Автор очень хороший инженер! Спасибо большое за видео.

[@PolyProject3D]

Thanks!

[@AiOinc1]

What you've built here is rather similar to a three speed hydraulically controller automatic transmission common in the 1970s If you ever decide to sell these as a kit that can be assembled, I would love to have one someday. I don't own a 3D printer and have no real use for one, but I would love to assemble and play with something like this.

[@PolyProject3D]

Hi, Thank you for letting me know!

[@bertdong1023]

3d printing + machining ! What a incredible duo

[@FletaNagine]

thank you for your dedication to excellence in every video!

[@user-qv1ex6lt2j]

this design is so professional

[@PolyProject3D]

Thanks!

[@Medvedevskihju]

this is so genuisly, to make clutches like this

[@felixyasnopolski8571]

This is actually how the clutches are working in the automatic gearbox :) especially old ones, 3-speed with OD. The only difference this gearbox have with real(!) automatic one - is a torque converter and control circuitry, which was done by oil pressure

[@TymekSondel]

Incredible gearbox and engine! :o , you should do a collab with Tom Stanton one day

[@mspeir]

And JohnnyQ90!

[@rick35149]

Man... incredible work!

[@jessebarker3602]

I really like this design. Very well thought through and unique. Love it.

Excellent work! I I follow several 3d printing engine folks, and this came into my feed. Your project is coming along awesome~

[@PolyProject3D]

Thanks!

[@djmips]

9:57 in auto transmission lingo these things you call clutches are simply called 'bands'. In that application the bands engage and disengage various clutch packs.

[@DrewLSsix]

They are clutch bands.

[@MichielvanderMeulen]

cleanly executed, attention to detail, with regards to production limitations, minimum amount of parts

[@willmarsden462]

Cool but I think the thumbnail needs a big red arrow and a 😱.

[@williamstock3007]

Hell no

[@captcade2913]

It would definitely grab more attention

Wonderful assembly and very professionally packaged. My sincere congrats.

[@PolyProject3D]

Thank you very much!

[@TheFordrt]

Absolutely fantastic, that you can get all the tolerance required with modelling and printing. That must have taken quite some time to get all the pieces working together.

[@hexagonal7708]

This design is super ingenious, great job man Also nice to see a constant air supply you should make a video of running all of your engines

[@PolyProject3D]

Thanks! that would be interesting!

[@jacquesb5248]

brilliant bit engineering! could sell that as a kit!

[@errrixon7309]

I want to see N and R in this gearbox ! Its so cool

[@razorblade7108]

I had a similar idea for some time now, but wasn't sure how I'd make the different planetary gears engage or disengage. My thought was that using clutch packs similar to an actual automatic transmission would be a good idea to have lots of friction with low wear, however that would require a rod system to pull the clutches together and possibly the use of synchronizer gears slowing down a planetary gear set before engaging. The idea with the clutches and the camshaft is much simpler, but I'm curious if the friction is sufficient to transmit high amounts of torque without slipping. Also the wear might be a problem over time, so I think a solution with clutch packs would still be better for practical use if somehow possible. I suppose it would also require two servos as one could only switch between two gears.

[@PolyProject3D]

Hello, (as a prefece the main goal of this gearbox is to be compact) the clutch rings provide adequate friction (they are made from carbon fiber re-enforced nylon) With regards to wear, the ring gears would most likely wear first and are easy to replace. However, Id like to build something into the gearbox to allow me to adjust the tension of the clutch rings. When I integrate this gearbox into a system like a vehicle, i will get a better idea of how it performes in that system and may look into implementing somthing to account for wear. hope this answeres your question. Thanks for the comment!

[@J2ko]

Marvelous!!

[@Wm200]

wow that is so damn cool!

[@Speedgaming802]

Awesome video

[@PolyProject3D]

Thanks!

[@SlinkySlonkyWaffle]

im really impressed by this, it also just looks quite sleek. even tho some ribs in cavities type of flair could definitely make it look much cooler~

[@PolyProject3D]

Thanks, I agree that would look cool!

[@Dazdigo]

Now you need to make a torque converter for this.

[@Dan-ry7ql]

Could use a slipper pad setup like Arrma 😅 if it works like I think they do

[@LDWorkshop]

Brillant !!

[@ahmetab06]

a great project, it can be used much more efficiently in robotic arm designs

Aldo the idea is nothing new, it's incredible if you have been designing this. Amazing, nice work !

[@PAKLANDTV]

Amazing. Would you please upload the engine video in similar detail?

[@PolyProject3D]

Thanks! I will make an engine build video including plenty of 3d printed lathe content!

[@PAKLANDTV]

@@PolyProject3D please explain too these engines are battery operated. or other sources?

[@lipoz-n-nitroz4012]

Incredible! Now all that's needed is an TCM (arduino?) to automatically control shifts/downshifts.

[@Exel_YTB]

that is very cool, i would like to see this but in lego form

[@haydenc2742]

If you could upscale that...and make it the size of those gocart engines...you just may have solved the gear changes for gocarts! So very awesome!!! Keep em coming!!!!

[@PolyProject3D]

It would be interesting to try that! Thank you!

[@sirmontag]

This is fantastic! Did you go to school for mechanical engineering or something similar?

[@technicbuilder6410]

Did you test how much torque your gearbox takes before ring gears start to slip?

[@Giggity-yt9nc]

How does the planetary gear touched/engaged ,it doesn’t get jammed?

[@devidtheyfar686]

Excelente y facil diseño

[@Daniel_Blake]

For the transmission. Is there be a neutral selection on that cam shaft selector. Considering you don't need to take away power to select gear. Would make it perfect for an RC application.

[@PolyProject3D]

Hello, mechanically the gearbox has neutral positions. but, It worked best for me to use the three position switch on my transmitter to easily select the gears. in other words, I electronically limited it to always be in gear. in future I might look into using another switch to select neutral.

[@dillpickle7633]

Lubricate the inner gearbox!

[@PolyProject3D]

Hi, I did lubricate the gears with oil but didn't show it in the video. inevitably, the clutch rings get lubricated as well. But they still provide enough clamping force (they are made from carbon fibber re-enforced nylon to increase friction)

[@erhardpostinger1326]

6:06 Der Aufseher erscheint kurz im Bild - hat der Oberaufseher nicht aufgepasst ;-)? 11:54 Die Muse findet den Fortschritt der Arbeit einer näheren Betrachtung für würdig und lenkt ihre Schritte entsprechend.

[@Giggity-yt9nc]

Can anyone explain me how it work? It’s quite unique,well thought out and fascinating.

[@PolyProject3D]

Hello, you can think of Planetary gear sets as having 3 primary rotating parts. there is the sun gear in the centre, the planet carrier in the middle and the ring gear. when one of these parts is fixed, the other two are constrained to rotate.
