3D-printed double helical gear pump/water pump/hydraulic pump *watertight*
Ғылым және технология
Recently saw a video of Boston Dynamics it's Atlas robot doing all kind of awesome stuff and learned that the robots were fully hydraulic. I was wondering if it would be possible to build a fully 3D-printable hydraulic system that's watertight and can be used for robotics. This double helical gear pump is the first component of the fully 3D-printable hydraulic system.
Note: The pump is watertight when using the 3D-printed lid with seal and seal tensioner. at some point in the video you can see me using a laser cut plexi lid, this one is only used for demo reasons, doesn't have a seal and so obviously leaks.

Great work, really clever design!
Very interesting project. Thanks for sharing 🙏
Very nice and thoughtful design.
Beautiful!
Great video,thank you fore sharing
Really professional design.
This is very similar to a Roots supercharger used on race cars! Great stuff!!
awesome, pleasant tunes
Great work
If you add an 'o' ring groove just in from the teeth on the top and bottom of the pump gears you can seal the pressure from escaping over the top and bottom of the gears. Should wear fine on the clear acrylic.
very clean. great work!

Thanks man 👍
Very cool design! Sealing off the shaft with a compression-gasket was a great idea. This seems to work very well in keeping the water in and the air out.
Very cool, looks almost identical to some I had played with designing back in school (I was using 608 skateboard bearings for the gears, which works well except for water they will eventually corrode, but would be excellent for oil in a hydraulic system). Best part is you incorporated the cheap $5 2212 brushless motors every hobbyist has instead of the Bosch motor I had used, and I'm pretty sure yours is working better than mine did!

I can't quite imagine how you were using 608 bearings for the gears. Did you cut teeth into the outside of the outer race or did it work with the bearings being unmodified? How was it assembled? Im curious, thanks :D

@@jansvasta2146 you could do it a couple of ways. Originally mine started off as a roots pump and had 4 external bearings plus herringbone synchronizing gears. You can put the gears recessed into the pump body (lid and base to support the shaft glued** to the gear), or for more compact the idle gear can have a 22mm shaft size hole and press fit the 608 bearing directly into that gear. **Instead of glue my shaft had an indexing T to transfer torque to the gear (easier disassembly compared to glue and no wait time), used printed shaft so the motor driven side I could have a recess for Lego shaft so it could flex in case of vibrations and motor side I made shaft to Lego shaft adaptor.

@@driftsdragsdrives4938 For most of mine I got them years ago on Ebay (just search "2212 brushless motor," or if you want a specific speed you can also search up 2212 930kv or 1000kv or 1400kv or 2200kv are the common speeds for that motor). You can also get similar motors on Banggood (they sell a lot of motors for airplanes and quadcopters as well as any other part you might need). You might be finding them bundled with an ESC at that price, which you will also need unless you already have an ESC. Then I also recommend a "servo tester" to send it the input speed (these are about $2), unless you are using an Arduino or similar to control its speed another way. It will end up being about $10 to $12 for the motor and needed electronics plus battery or other power source (like an old computer power supply, or car battery).

There is just one other thing ,overlooked - the inlet and outlet should be doubled up to attain a bigger flow rate.
Really nice! I printed a similar design ages ago but lost interest and never assembled it, looks like I really should give it a try! In the last little video it seems it has developed a little leak, is this just because of the transparent lid or what?

Yes in the last part of the video i used a plexiglass lid for demo purposes and this lid doesn’t have a seal so the fluid comes out through the driveshaft.

@@BrianBrocken Love the design. Nice work! I am guessing the plexiglass lid wasn't intended for actual use - but if so you could probably 3d-print a seal similar to the first cover that glues onto the plexiglass below the gear, where you can't see thru the plexiglass anyways.
How small do you think this could scale down? how big? and do you think maybe printing the gears in say nylon would reduce noise/wear?
Nice last end 🤔👍🏻
What water pressure pulls? Do you have another video of the output end?
Cool whaterpump.
Cool stuff buddy. How's your unit's noise level compared to when you use cylindrical/spur gears instead ?
3d printing is 👏👍

I been trying to design something similar, but I was using simpler gears, i think, that I'm gonna try double helicall gears now
I would add a support for the top end of the motor shaft. You can see it’s vibrating, which is wear and tear.

Love the Video, and I have a question. Is there a specific reason you didn't use the double helical gears above as well? With the 3D printer, they shouldn't be more difficult to build, especially since you already have to print two for the pump, but they sholud run much smoother and quieter than the normal gears. I´d love to learn more about it.

Only reason I used regular spur gears on top is for ease of assembly. Spur gears can be slid on the shafts into each other, this is a bit harder with double helical gears.

I've seen similar build from other channel but the quality of the build is just stupid!, leaks everywhere, bad suction power. The design in yours are by far the best I've seen!! also involved many attention to detail like the gasket seal, shaft inserts and stuffs. bravo!!

Imagine you used this for those Water Pipeline all across the world. And run those water factories by solar and wind.
Not a lot of ppl know oil or fluid flows on the outside wall of gear pumps.
Nice 🇮🇹🇮🇹

flow per minute?
Nice design and presentation! Wouldn't the motor be powerful enough to be connected directly to the shaft of the helical gear? It would reduce noise a lot and friction a little.

Thanks, yes it might be possible, this just seemed the easiest way to integrate the motor with the design at the time as it already had a coupling to secure propellers.

@@BrianBrocken Oh, I see, it's an RC plane motor :-) Admittedly putting the motor on top wouldn't look as nice. The best idea I can think of to make it both quieter and smaller would be to insert alternating magnets at the bottom of the helical gears and some flat coils underneath, effectively making your own mini axial motors, and the compression seal wouldn't be needed anymore as the gears could be completely sealed in. Could be a fun project to experiment with.

Very nice...much better than others I've seen who rely on glue instead of gaskets... That being said...claiming it's water tight when I can see the water fling onto your motor...a bit strong of an ask. Very nice work though.

Thanks man, when using the plexiglass lid there is no gasket used and the water escapes through the gap between shaft and hole, this is only used for demo purposes (also mentioned in the video). The 3D-printed lid has 2 gaskets, 1 surrounding the lid and a compression gasket to seal of the shaft. The pump with the 3D-printed lid and gaskets is 100% watertight.
