900W Crazy Powerful Gearbox With SIX 775 DC Motors - 3D Printed

This video is viewer suggested. When two months ago I build this same thing using 8 micro motors then this time it's upgraded to 775 DC motors. In design, I made a lot of improvements. For testing, I attached this new gearbox to a water pump and snow blower. This 900w gearbox has a lot of power...

Breaks a metal coupler not the 3d printed part 😂🤘👍

[@kingmasterlord]

How about this community though? I scroll through these comments and I see nothing but helpful suggestions and congratulations, hell yeah

I work at a chemical plant and we have cooling towers that circulate water with direct drive centrifugal pumps. Usually between 1700-3500 rpm. They usually have an inlet of 4”pipe and outlet of the same or smaller depends on pressure needed. They deliver about 60psi on average on outlet side. It would be cool if you encased this pump in a similar system that could build pressure and added a gauge to see how it measures up. Maybe next time include rpm tests as well on the impeller. I know it’s a lot of work but I think it would be worth it. Keep up the great work man your videos are some of my favorite. It’s awesome to see someone apply their knowledge, and conduct cool experiments.

[@etherealswordsman3214]

When it gets warm enough to do water-based projects again, i think it'd be really cool use this extremely powerful pump to build a giant version of those Vortex Fountains that were getting popular around youtube a while back.

[@mr.stealyomemes1393]

I could see a lot of practical applications in a small, portable, battery driven pump. If you’re out here in Australia 4wding and you need to fill water from a tank or stream, instead of manually filling jerry cans, you could pump it. I would love to see flow and head tests as well as wear tests. I wonder if anything would change if the gears were made of aluminium?

[@1963corvette327]

that would be cool in a model boat

[@thepvporg]

The end bolt should be spaced with a thrust bearing.

[@user-xg8it5sq6q]

I can sense the burning smell of coils by watching this.

[@user-pv5yh4de6f]

기계기술이 대단하십니다

[@Holy-Terrorist]

**=** Electrify the gas snow blower, the dream!

[@aidan5320]

You definitely need a flywheel with some weight for the snow blower application

[@coughfee1416]

How about a very fast blower with a hopper that lets in the snow that you shovel for more efficiency

[@barrydheil]

The snow thrower design reminded me of the ones they have on the front of trains, except the blades are a bit like a jet turbine. They are commonly known as rotary snowplows.

[@theorangebaron1595]

Love the videos! The combination of gears, 3d printing and rc makes one of the best channels on youtube! Also, what cameras do you use? Editing software?

[@cuf_]

Can you try making is using Brushless dc motors? This should give it more speeed

[@mark8664]

Put it vertical axil. Wonderful!!!

[@waynvideo21]

Очень классные проекты, браво 👏

[@oniontaster6449]

if you use a wood-burning pen with some fine wire mesh over it, you can plastic weld really well, i would recommend for durability purposes to plastic weld the joint on the gear box

[@pointbreak5906]

Do this with 8 dc 775 motors and slimmer please... New subscriber❤

[@waynefilkins8394]

pretty crazy when u 3d print most of it and the metal part breaks first lol

[@waynefilkins8394]

HOLY SHT THIS IS AWESOME. I just learned how to design those bevel gears in cad too. Gonna have some fun with this :)

[@Argosh]

Get a Turnigy Aquastar BLDC watercooled motor, drive an impeller directly from it. It takes up to 10S at ~100A so about 3kw. Just mind you, it's a weapon XD

[@crispychicken2743]

Nice job, but the end results as a snow thrower is wrong . Application should be better

[@rowmen6293]

The snow disintergrate into particles haha

[@ScorpionHH9]

I'm going to chat in the comments every day Cause you're my favorite youtuber

[@savneetsinghrairai6823]

Add double ball bearing at both ends that will increase speed last long

[@hellNo116]

that is one horsepower. nc!

[@luckygunner8089]

I would really want to make a RC Jet boat with this. But I dont have those skills.

[@luckygunner8089]

Maybe watch the video before commenting. Glad ve gave sort of the same idea

[@molusco3671]

God project man! But I would make with brushless motor!

[@renzbenjaminrsawit2641]

6:49 the way it just popped off lmao 🤣🤣

[@HumanBeingSpawn]

6:50 I think the snow blower would work well if the blades are angled

[@cedricbrun4241]

Hi very cool andinspiring video, to help with layer shift you should greas up the 3D printer, verify if the grub screws on the steper motors are tight, and to prevent nozzle clogh verify if your extuder gears grab the filament properly you can also increas the température to 230°C for PLA (even 235°C), or use a bigger nozzle like a 0.6mmø but keeping layer hight to 0.1 or 0.15mm to achive good quality. Can't wait for more !!

[@tolerancija]

Ah Estonia. You should concentrate on the winter projects :) Greets from Croatia!

[@thedarkrs1]

you should definitely have more subscribers. You need to build this with brushless motors.

[@momue100]

Maybe print a disc with 2 or 4 razor blade holders for the gearbox and use it as leaf/ small twig shredder or for carrots

[@CLAUDIOSRC9529]

excellent edeia dear friend I liked it and subscribed

[@drsatan9617]

Could you make a small one of these to combine 4 drone motors to use as wind turbine

[@stargazer7644]

The 90W or so of heat you're going to be dissipating in those gears under load isn't going to be kind to PLA. You really need some grease in there.

[@MohiuddinAhmed007]

Like this new build. Why not try to build a electric car from this new powerful motor system!

[@sethkill466]

Ive designed somwthing similar a few months back using 4 380 sized motors for my rc truck im building

[@celik.gokhun]

You should add freewheel this type of system which have different load conditions.

[@genkidama7385]

you need to add silicone seals. you can create custom ones, if you design your parts with a special channel, you can pour liquid silicone directly in the part. there is a video about this, some guys building Submarine doors, i mean heavy duty steel ones, you can see clearly how he builds the insulation, as i described. when the door is closed it presses onto the silicone seal, thats how no water can pass through. normally people use premade seals for plumbing, but since you are 3d printing everything, you also need special seals.

[@vancedburner8052]

If you have the money, use brushless motors. Waterproof, lighter, and far more powerful.

[@r5LgxTbQ]

I think a flywheel could really help that snowblower keep its inertia

[@matheusa3160]

Please make a RC car with this!

[@MagicGumable]

How about using it to power a flywheel which is then attached to an air raid siren or similar?

[@MontagoDK]

Maybe use stainless steel and also protect the motors from water so it doesnt rust / corrode and get destroyed so fast ?

[@anjelomarickaviles923]

Make a even powerful one using a boeing 747 engine

[@GeweerBeer]

You should compare it to the performance of a single 900W motor.

[@nunamvseravno]

You need to include a small steel ball between the main shaft and the rear adjusting screw.

[@AsherLimaPapa]

Absolutely fantastic work!

[@pudgip2855]

Liked just for that intro

[@Tusai]

Use Brushless Motors, And gear it for torque, and run the motors at 10-20 thousand RPM.

[@MannyTheSpook]

Can you use this concept on an RC Car. Like a 1/10 scale

[@screem_mix]

make a boat with this motor

[@paulmaydaynight9925]

to replace the big bolt stop sticking out, just take a bit 0f springy thin copper coated steel, centre punch it or rather punch a tiny ball bearing to make a dome in it, cut to size so the dome is contacting the centre steel rod & the plate can simply slot in the sides to keep it pressed together... or plastic + hole + ball bearing + spring oc but that's fiddly & can drop out easier

[@TheBowersj]

this is more than epic... really ... I am speechless

[@khimroy3958]

All the motors must turn at same step to reduce the resistance

[@jonathanlunger2775]

Subbed to see where this gearbox goes! Only issue i see it having is cooling

[@jeremias5737]

Awesome, asombroso mi amigo 👋 from Mexico

[@brannorm3531]

Why not an Archimedes' screw pump... it is much better mechanism for pushing liquids evenly

[@rafaeladamovic330]

Make snow blower plese!

[@tintinderet7370]

You found a nice way of cleaning your shower room :-) . Very interisting design and nice work

[@Lucas_sGarage]

i think that with some gearing this would have the torque to power a gokart or somethink similar

[@johncuddeback8399]

I’m gonna ask possibly a dumb question but do you think something like this would push a kids electric vehicle?

[@dodman.]

What if you put one in a car?

[@ziad_jkhan]

Considering the high wattage, it should be able to lift the weight a lot faster. The absence of slowing down as the weight leaves the ground shows how much power is still untapped into. Try reducing the gear ratio.

[@v.bapureddy7919]

What is the total cost and where it's available and what's the strength of battery needed

[@gaussgreen7921]

why you moved from spiral to straight bevel gears ?

[@leoyru.3361]

but why the gears have suport to print ? did you tried to print it upside down to not needing it ?

[@sanderluis3652]

make a RC boat with it

[@papycoima]

Imagine having this as your pc cooling fan

[@SciSenkra]

Have the double one but make it wrap around to 1 nozzle

[@pablo_7992]

you can use this for make electricity?

[@LBCAndrew]

My only criticism is your use of lock nuts. I would use threaded inserts. The kind made for 3d printing that you use a soldering iron to melt into the hole.

[@scratchbuilder101]

Why will only 2 of the 14 files open? I would really like to build this.. Thanks.

[@pinngg6907]

can you make it look like a V6 engine instead of boxer engine? It will look cool and save a lot of space!

[@hassankhurramtech]

okay, but what's the productive use of this project? someone enlighten me please.

[@Carpatin7202]

Whats the name of the sound effect used at the beggining of the video,sounds Badass

[@genalphalyrics8729]

Make a means of transport from it like a car or a bike

[@popman10001]

Try attaching it to the compressor side of a turbo from a car with a gearbox like the other video just in reverse

[@marktsarenko3943]

can you please make a video on how you design stuff like this? Like what program and stuff

[@klam77]

PETG material? for chemical resistance? strange no?

[@Mesugea]

Not using brushless motors it seams to be a good excuse to print a bunch of gearbox ;D

[@s.sradon9782]

Water cutter time?

[@sspence65]

I'm thinking of upgrading my electric boat ...

[@joejia1410]

Damn!

[@jimi7170]

Did you figure out the reason why your printer stopped extruding mid print. I have the same issue

[@jiteshsoreng4852]

Thats lovely. 💜 Edit: liked & subscribed keep it going. 👍

[@papycoima]

Can you do a tutorial on how to make this type of gear with cad software?

[@mashupvital2400]

can you make something that match a Honda snow machine ? And what comes on my mind, what is the wear on the gearbox after long time of normal use ? and can this break easely under too much load ?

[@GenaTrius]

Are you telling me that if I wanted to make good fast electric bike, I don't have to buy a huge high power motor? I could just buy a bunch of little ones and use a gearbox?

[@dannymcwilliams1656]

car you put it on a bike?

[@manuelpayam6895]

Hello do you sell your New Ratio 2.1 Gear box too?

[@enohaime1960]

How can you increase torque in such a project?

[@akshatjohri5241]

Can you make a rc car with this electric engine

[@jasonhaymanonthedrawingboard]

Could you run the gear box reverse as a generator?

[@GoldenPants64]

Looked like the water output was about 25mm which would assuming high peak flow maximum would be around 220 liters per minute. Just increasing 5mm more would nearly double output. By restricting the output it is killing the efficiency and hardly competing with a $100 pump. I have a 18,000lph pond pump that runs a 2” (50mm) output for reference. I’m positive your setup exceeds what 25mm can allow.

[@diy9990]

Hay man try to use 2200kv bldc motor...

[@rifkyramadhan6889]

What names type gearbox ??
