Extremely Powerful 3D Printed Gearbox & Water Pump - Eight Electric Motors

Gearbox and water pump are not new things in this channel, but I was thinking to make the best, most powerful, and insane soo far what I have ever done. Well, here it is. Gearbox with eight engines what is driving water pump what is attached at the front.

I like that it has some system redundancy, great for remote operation, and uses cheap motors, coupled together to get reasonable, and scalable, Power...

For water-tight shaft housing, check out a "stuffing box". Basically, you make a cavity for the rod to pass through, and you stuff the area around the shaft with valve stem packing material that's a cord with graphite lubrication on it. The packing allows the shaft to turn but creates a water tight seal around it. This is how some faucets and ships have a rotating shaft that prevents water from seeping in.

So putting 8 motors in parallel gives you a lot of power which is great if you have a huge mass of water to displace, but it does not increase the pump speed. Perhaps though you could find a configuration to increase the speed of the motors dependent on the load exerted?

[@milesprower6641]

For durability upgrade on metal contact in end of the rod. Make sure both surfaces are cut straight, center punch mark on the both and drill very shallow hole using say 10mm drill bit. Get one ball bearing ball, apply little bit grease, hold it on place and tighten the bolt. This way you have smaller contact surface creating less friction and hardened ball bearing ball wont wear out that fast. If you are worried bearing falling out, there are those long nuts that you can tread over the bolt that prevent bearing ball from falling out. Of course this is based on what ever those gears can last more than day continuous use, but mentioned friction could start melting plastic, so its worth to do such minor modification. For water leaking, you can use silicone on axle and bearing inner race and make flexible disk that connects to shaft, put generous amount of grease between the disk and frame, this way if pumps pressure increases it will push disk against frame and works sort of one way valve. If pressure wont increase disk will just cause small amount of drag moving the grease around keeping healthy amount near the axle and bearing preventing water getting to bearing. Optimally you want to get water sealed bearing for that combined with silicone on both inner and outer bearing races, but that DIY sealing should work ok and for those who have difficulties to find sealed version of said bearing.

@@ryanrinn4041 Depending on how you wire them the same ESC could control all 8 of them. It might actually be preferable as you wouldn't want any one motor to be out of sync with another. Just make sure to calculate the voltage so the ESC can handle what you attach, and scale the motors down so they don't overwork it.

[@Green__Man]

@@Scott_C I wouldn't put more than 1 brushless on an ESC, it might work on the bench top but under load the ESC will freak out. I'd use a single bigger motor or maybe a couple slightly bigger motors and give them an ESC each, they're cheap and literally plug and play, easy

Suggestions, first, look into sealed thrust bearings, they would work really well in this situation. Second, leave a gap between the impeller section and the gearbox to give leaking water a place to go other than the gearbox. Third, more thoroughly seal the impeller housing and seal the gearbox, with covers for the motors. Fourth, use grease(preferably marine grease to reduce pollution issues). It should reduce noise, protect the surfaces from friction damage and help waterproof the system. Fifth, grind flats on the shaft where the set screws on the large gears will be. Set screws do better at grabbing a flat surface than a curved one. And last, look up a better impeller geometry. You can make any shape you want with a 3D printer, you might as well make an effective one

There are already pumps on the market that have the axel exposed so we can attach them to my screwdriver and just start pumping. The last one i tested with my Festool seemed to have more powerful flow then your 8-engine-model, but i dont know cos i dont see any numbers on water flow or power consumption on yours..? And if you exchange the 8 small engines for 1 big one that is equal to the 8 you got, would that be better or worse? The gear-ratio seems to be ~1:3, why did you chose that and not 1:5 or 1:2..? Have you done any testing to chose this specific gear ratio? Have you tried to just put the pump-part (without the gearbox) with an exposed axel on a good battery powered screwdriver? Or maybe to print a better small 2-wheel (or more) gearbox for a screwdriver? I mean you write that its sposed to be "the best, most powerful, and insane..." but if you dont compare it to what already exists on the market, or other gear ratios, or even other pump wheels, how will u know? With the gear ratio you chose it looks like you could attach a bigger pump/wheel to it, wouldnt that make it "better, more powerful, and insane"..?!? Im honestly just wondering. So can you give us some stats for it so we know just HOW "powerful, and insane" it is? "Best" is after all to a large part personal opinion...

A number of issues: That kind of motor rusts really fast; electrical steel rusts fast anyway, but discount motors tend to rust the fastest. You only need one of the larger gear; make it dual faced and arrange the motors around its perimeter, alternating faces; this also obviates the need for the axis pinning screw. The orientation of the print allowed the motor mounting holes to split (3:45); design the motor mounts to be separate from the central hub enclosure so that all pieces can be printing in orientations that are a lot more durable. That impeller design has terrible efficiency for that task; google better impeller designs.

IIRC he used 260-sized motor, while rated for about ~18000 RPM, they do not have the torgue by themselves (hence he needs 9 of them?) and likely overvolting as these are rated for 6V (you could hear them scream) so won't last long with copper brushes. I am not going on a witch hunt to look for the video where he tests this, but I believe the choice was based on cost.

Твой инглиш такой же как и мой, не валяй Ваньку, переходи на русский 😂

Не, он под индуса косит. Индус с клеем-момент.

[@anzu8967]

Чел с Эстонии похоже. Далеко не факт что он говорит по руссише.

[@МаксимРунге]

да ладн, пусть хоть на хинди балакает... нах восемь моторов, когда хватит и одного, чуть помощнее, судя по оси и толщине импеллера...

[@bearb1asting]

Sad that you glossed over the solder. As for the other parts, maybe some wrenches. Nice audio. Excellent camera shots. This would be great for making emergency pumps in disaster areas.

[@calinbaciu]

Use power supply, not battery. From motors to the power supply you must have thicker wires. Very nice!

[@mrmexicano64]

You should work on the propeller profile to make it more efficient. I'm sure you will get much better efficiency out of the pump if you improve that

[@KieranShort]

Lift heavy things with it. Can it lift a car?

[@LetsPrintYT]

Idk yet, will see on future video XD

[@KieranShort]

Haha, it will be a big views video if it can i think. But you'll probably need to connect with a big channel to help promote it. Think 3D Printing Nerd, or Makers Muse perhaps.

Как то дивно смотрится наш клей на канале с англ языком. 1:11

[@ГеоргийКачалов-р8ы]

Акцент выдаёт его)

[@РоманБыковский-р8у]

Надо чтоб по русски комментировал

[@MrNeytrino]

@@РоманБыковский-р8у ИМХО, лучше уж сабы тогда... так хоть забугорные будут смотреть что русские тоже не пальцем деланы. Кстати, ждал или индуса или нашего (по акценту)))

[@ЕгорВиттман]

номера на машине не русские и язык на ютубе тоже, моменту удивился, видать идет на экспорт без перевода

[@magnuswf]

This is the first video I've seen from your channel. I liked it, and clicked your channel and I see you have 19 other videos of the same category. I Insta-subbed right away :)

[@johnv341]

me too! johnsmachines.com

[@LetsPrintYT]

Thank u a lot, this positive feedback means a lot of me! ;)

[@Scott_C]

I instant subbed the second I read the channel name. 😄

[@HoztileMANIkyn]

fantastic work! but mabey a clear acrylic box to cover the pump? don't want to short the battery

[@blade913]

I would've put some grease in the gears, it would've helped them move more smoothly. Not sure if it would contaminate the water, just a thought. Silicone oil isn't bad, but you'd want something that's thicker, that likes to cling.

Опять эти русские, которые критикуют всех за произношение.

Parandus, mitte Eesti keelne vaid eestlase tehtud kanal

[@ekkekrosing8454]

Jah

[@henmich]

My thoughts exactly...

[@aidanmanuel7254]

7:31 : According to captions this is music and an applause at the same time. Tf is wrong with you KZbin

[@Crimsomreaf5555]

How fast the battery drain? Would actually make a great outdoor water pump to a camp. Or is this not as powerful as a gas water pump?.

[@FutureChaosTV]

Am I seeing it wrong or are the retrofit sleeves covering up the cut out cooling vents for the electric motors? Do the motors heat up much?

[@pflernak]

Kirjelda, mis tunne on vaadata statistikat stuudiost? :D

Natukene harjumatu, kõik näidikud mis enne olid kõrgel vms, neid pole enam nähagi. XD
