900W Crazy Powerful Gearbox With SIX 775 DC Motors - 3D Printed
Вставка
- Опубліковано 1 жов 2024
- 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 😂🤘👍
i need asnow blower why dont you aim for a snow blower :)
Your background music is improving :)
and the really cringy music around 3:20 made me skip until the shower test when it stopped
3:02
Could you do this via the "last gear" being duel sided, and having another set of bevel gears to "lock that side in" ?
Was looking for this comment. This change would eliminate the need for an extra thrust bearing and reduce friction losses and wear. However, instead of a dual sided last gear, that would need support material, I would simply flip one of the big bevel gears 180 degree
Idea: Make a "Centrifugal Fan" with the whole high flow/pressure thing.
Would be for a fully diy version of this:

(ie not needing those 150+ USD motors, but maybe someting more reasonable)
I'm looking forward to your water jet drive project. I've been messing around with 3d printed water jets for a while and I will tell you some findings I made: With fdm printed parts, clearance is your friend. I recommend to make the OD 2-4 mm bigger then the impeller diameter (yes, this is inefficient but inevitable) And either use 2 bushings for the impeller shaft (one on each end) or make the support free distance to the impeller as short as possible, to avoid oscillation of the shaft end and impeller (can destroy the whole jet otherwise). When using the method of 2 shaft bushings, I recommend using a stator impeller with counter directed blades. This will take the vortex out of the flow ( more efficient and looks better) otherwise, a diffusor behind the impeller works fine too, but makes the system larger and heavier. If possible, try to make an impeller with overlapping blades (alternativley multiple stages) to decrease impeller slip and thus increase the thrust (but keep in mind you will also draw more power then). I also recommend a high pitch impeller. Furthermore, keep in mind that in an ideal pump, if you double the rpm, the power draw will be 8 times as big (2^3), that means when you double the voltage on the motors, that is directly proportional to the rpm, your current will quadruple. So always keep an eye on the current draw to avoid motor burnouts ;)
Wow, I lucked out here! I've been trying to build a 3d printed jet for a while. That's a lot of nice tips, thank you!
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?
How about this community though? I scroll through these comments and I see nothing but helpful suggestions and congratulations, hell yeah
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?
Can't wait for that boat!!!
The end bolt should be spaced with a thrust bearing.
I can see your editing skills improving (Y)
Use that at snowblower
Nice job, but the end results as a snow thrower is wrong . Application should be better
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.
But you need to supply sufficient current at rated voltage to achieve maximum torque and power
746W is a Horse power ... It is more than A Horse power
Would love to see the waterjet engine !
Once the motor get heavily-loaded, no 3D filament can stay mechanically strong with the heat from the motor. PLA is especially not heat resistant, with only 60℃ it will become soft.
Reports of getting up to 180°C if you use high-temp PLA and anneal it (but you’ll need to adjust your part for shrinkage/expansion and could try with your slicer’s horizontal expansion setting): ua-cam.com/video/vLrISrkg46g/v-deo.html

idk if you noticed this, but it was in snow
Try using a belt drive instead of a drive shaft. Less chance for a snapped coupler :)
Chain drive, belts snap too at this speed and torque especially when it's freezing cold. Also make a chain cover.
@@Scott_C That's an interesting point. I was thinking of the belt on my 2 stroke Toro. I wonder what the potential output is on 6 x 775's with high discharge DC current
@@partytempo Not sure, would love to see him calculate/test to find out. The torque I was specifically thinking of is what you can hear each time he threw chunks of snow into the "impeller" you could hear the sudden drop in speed and then the sudden ramp up as it cleared. If he's got a belt that can keep up with that type of inconsistent torque pull and not get blitzed at those temperatures, then by all means go for it. If not a chain drive most likely is a better option. This also makes me think that he'll need to make some sort of transmission or torque control for this snow blower project.
@@partytempo how do you like your Toro BTW? Thinking I might need to get one (a snow blower that is).
Edit: to clarify what I'm thinking of getting.
@@Scott_C - Overall I love it - cheap, effective, reliable. With all 2strokes, it's loud and gassy. I just upgraded to a Toro 824 which I look forward to testing in the next snowfall
Mare levu se gearbox
What if you put one in a car?
Hay man try to use 2200kv bldc motor...
posted this as a reply to a comment but I wanted to get more input from a wider audience. This was a reply to a comment about using a belt drive instead of a drive shaft/coupler:
I'm not sure of the torque, would love to see him calculate/test to find out. The torque problem I was specifically thinking of is what you can hear each time he threw chunks of snow into the "impeller" you could hear the sudden drop in speed and then the sudden ramp up as it cleared. If he's got a belt that can keep up with that type of inconsistent torque pull and not get blitzed at those temperatures, then by all means go for it. If not a chain drive most likely is a better option, also more easily found on an old bike.
This also makes me think that he'll need to make some sort of transmission or torque control for this snow blower project, and a chain drive cover.
You definitely need a flywheel with some weight for the snow blower application
I can sense the burning smell of coils by watching this.
This is so cool. I'd love to combine a couple of CNC spindles.
why you moved from spiral to straight bevel gears ?
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.
Oh mah gawd, USING PLASTIC GEARS??? Those will age faster than my grandmother... Hate to break down to ya, But you gotta use cnc'd metal gears...
I'm thinking of upgrading my electric boat ...
Excellent
amazing
Why will only 2 of the 14 files open? I would really like to build this.. Thanks.
How about using it to power a flywheel which is then attached to an air raid siren or similar?

good idea, instead to drink a vodka :)
6x motor in car
Why not an Archimedes' screw pump... it is much better mechanism for pushing liquids evenly
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?
yeah its cool and all, but you dared to use a Phillip's screw in this build. Objectively the worst screw. sorry fam, ill have to deduct points.
Can you try making is using Brushless dc motors? This should give it more speeed
I’m gonna ask possibly a dumb question but do you think something like this would push a kids electric vehicle?
that is one horsepower. nc!
I'm going to chat in the comments every day Cause you're my favorite youtuber
okay, but what's the productive use of this project? someone enlighten me please.
Whats the name of the sound effect used at the beggining of the video,sounds Badass
Awesome.
Sul on PH2 kruvid aga kasutad PZ2 otsikut, see on põhjus miks kruvid üle keeravad. Ümara peaga on PZ2, lapikud on PH2.
Do this with 8 dc 775 motors and slimmer please...

I want to create an electric super charger or turbo charger for a go kart! Can I collaborate with you! I'd print it and test it out. I'd like to use this same gear box but with a turbo or super charger on the end
perde a força do motor devido ao tamanho da engrenagem do motor perca de torque
Ne gustaria obtener los archivos STL.
Делаешь прикольные вещи, но печать убогая
**=** Electrify the gas snow blower, the dream!
I would really want to make a RC Jet boat with this. But I dont have those skills.
Maybe watch the video before commenting.
Glad ve gave sort of the same idea
all nice. but it is not practical. think of something more practical and more useful
PETG material? for chemical resistance? strange no?
excellent edeia dear friend I liked it and subscribed
This intro is awesome!
How about a very fast blower with a hopper that lets in the snow that you shovel for more efficiency
Damn!
What is the total cost and where it's available and what's the strength of battery needed
Next level stuff!!!!!!
Waiting for a gearbox into a Kids car with this project hahahaha
Could you make a small one of these to combine 4 drone motors to use as wind turbine
but why the gears have suport to print ? did you tried to print it upside down to not needing it ?
Keep up the good work! Happy new year!
Thanks mate! Happy new year! ;)
Can you use this concept on an RC Car. Like a 1/10 scale
Use Brushless Motors, And gear it for torque, and run the motors at 10-20 thousand RPM.
HOLY SHT THIS IS AWESOME. I just learned how to design those bevel gears in cad too. Gonna have some fun with this :)
Make a even powerful one using a boeing 747 engine
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.
Hello do you sell your New Ratio 2.1 Gear box too?
you can use this for make electricity?
12x 775??? :)
What names type gearbox ??
Can you make a rc car with this electric engine
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
Your printing quality is not good
Put it vertical axil. Wonderful!!!
Make a means of transport from it like a car or a bike
Use some lubricant
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.
my grandpa need this for pee
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 !!
naa your using it wrong put in some potatoes
can you make it look like a V6 engine instead of boxer engine? It will look cool and save a lot of space!
Imagine having this as your pc cooling fan
Man, you are printing really slow, i suggest don't using exagon infill, it's insanely slow and 100% infill Is almost useless, a part with 5 layers and 35% infill Is 90% as strong
Thats lovely. 💜
Edit: liked & subscribed keep it going. 👍
If you have the money, use brushless motors. Waterproof, lighter, and far more powerful.
how can it be 900 watts if there are 6 150 watt motors? Each gearing connection has efficiency losses. You are going to lose about 10-20% just from that not counting any other inefficiencies in the system.
powerful seems to have other meanings all around the world hahahaha
i think that with some gearing this would have the torque to power a gokart or somethink similar
Hi, please price the 3D device
Ive designed somwthing similar a few months back using 4 380 sized motors for my rc truck im building
Can you do a tutorial on how to make this type of gear with cad software?
👍
