Wind Powered Lego Gear Machine

Different unconventional gear types that Lego does not make, all integrated into a Lego display machine that rotates the gears and itself. The machine is wind-powered, utilising a vertical wind turbine. The shifter turns the machine 1/12 of a revolution at a time, while only displaying one gear at a time to reduce friction.
All the gears have been 3D printed using an FDM printer and Silk PLA. I designed some gears myself and also redesigned others to fit perfectly within Lego dimensions."

Looks like someone had lots of fun with his 3D printer. Cool stuff.

[AwesomeDomi]

Those paradoxical gears are actually so awesome, I’d love to see a closer look at how they work

[Ze_Techno]

Gotta love the advanced air ventilation system

[aashes]

Would love to see more of these custom 3D printed lego parts. They seem very mechanically versatile

[alexela_]

I love the usage of 3D printed parts! It's another level of creativity!

Edit: If only Lego made a website where you can suggest parts to be produced.

[Pumble]

I know that lego constructions are super expensive, take this little help to put an smile in my face with your videos

[Ignonym]

Thank you for including the proper names. I've been trying to figure out what hypoid gears are called for ages now--I'd only ever heard that mechanism referred to as the "low-center drive".

[RNdin]

Harmonic drive gears are interesting because they are incredibly compact while also having an incredibly high reduction ratio and none of the sliding contact or axis change that you get with a worm gear drive.
Because of this, they have a lot of applications in robotics, like driving the elbow or knee joints on a bipedal or quadrupedal robot like Boston Dynamics makes. The alternative in those cases would be hydraulics, which comes with plenty of its own problems (mostly about how to keep the fluid IN the system, and not "dripping on the floor").

"advanced air ventilation system" has no business being as funny as it is

[Jack-O_hedgehog]

0:06 I at first thought that said "Congratulations"

[elanjacobs]

Just a technical note...your helical gears are a special case called screw gears or crossed helicals and are more closely related to worm gears in their operation than traditional helical gears.

[YablokoG]

1:25 these are actually the gears that Citroen's founder initially invested in, and made a lot of money with them, cause they're much quiter when used in industrial machinery. And the logo of the car company represents these gears

[Kekatronic]

some of these gears have me going "what the hell that's not allowed" those damn paradoxical gears

[MawDaws]

how long will it be before you build an entire wind farm out of lego?

[liliowen]

I'd say the Cycloidal Gear is my favourite one, because of the grey wavy bit at the top. So satisfying. Also the Hypoid Gear looks like my bath/sink plugs (just not the kitchen one, that looks different)

[OneAdamAdam]

I have no words for how beautiful this is.

[brazz_yt]

i want this guy to build a BIG Lego engine it would be awesome

[smilerbob]

There is something hypnotic about watching pardoxical gears rotating from the side angle…In could relax to that all day everyday

Edit: I have just seen the cycloidal gear 👍

[Zaque-TV]

This channel teaches me engineering above all else, which is really cool.

[KenjiLaurvick]

I need to see a video where you chain as many nautilus gears as possible
