@@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.
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!
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
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.
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.
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
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.
Для модели это очень красивый дизайн! Мягко говоря я поражён сегодня такие вещи делает один человек... Автор очень хороший инженер! Спасибо большое за видео.
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 ...
Can't believe how compact this thing is! Earned a subscriber! What printer settings did you use for such a high resolution on the gears? Did you use a tighter nozzle?
next episode: making 4x4 wheels with my mini 3dprinted motor build next episode: making my mini 3dprinted electrical system next episode: making my mini 3dprinted car body with electrical doors next episode: tuning my 3dprinted car with spoilers and airflow adapted bodykit lol, i liked it.
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!!!!
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.
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!
MAN this is SOO COOL!! I am designing also busy designing a 3-speed mini Transmission, thought yours is WAYYY better haha May I please have the files for it?🙏
Very slick can we buy the plans from you or do you have any other documentation available? My dad is a retired mech engineer and would get a kick out of building this.
its such a shame storing any meaningful amount of compressed air at the micro scale is basically impossible, because an air engine like this on an rc car or airplane would be an absolute _riot_ for a fraction of the price of nitro engines
Тут есть существенный недостаток. Без смазки этот механизм долго не проработает, а как только ее добавить перестанет работать механизм остановки коронной шестени
202 / 5,000 Каждый компонент коробки передач смазан, и да, смазка попадает на тормозные ленты, они изготовлены из нейлона, армированного углеродным волокном, и обеспечивают более чем достаточное трение во время смазки.
