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.

    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!

    @@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).

    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.

    @@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.
