I've been staring at this for 10 mins. May I present to you, a skew axis enveloping gear. (i.imgur.com)

Double skew axis enveloping gears!

[–]mp33 1 point2 points ago

Thank you. This is sooo awesome!!

[–]MrWhite2020 1 point2 points ago

What uses these types of gears?

[–]asdfghjkl124 1 point2 points ago

The window motor in your car door uses a simpler worm gear. This however, just looks like an overly complex worm gear. The only difference would be increased surface area and therefore the teeth are less likely to break. To me this looks like a prime example of over-engineering.

[–]Bassinator 2 points3 points ago

Would a kind soul care to explain why one wouldn't just use a normal gear?

[–]SpaceNerd 6 points7 points ago

"Nonenveloping gears have low power-to-weight ratio and are used mainly for motion transmission between skew axes. An increase in power-to-weight ratio is achieved by arbitrarily fabricating a cylindrical worm and using an identically shaped cutter to manufacture the mating worm wheel using a generation-type process."

From "Kinematic Geometry of Gearing" (page 31-32) By David B. Dooner

Essentially it is a fancy way of increasing the amount of torque without adding more weight to the current system.

[–]greaseburner 11 points12 points ago

Hmm, yes. I know some of those words.

[–]djkeysr4 0 points1 point ago

no idea really, but it might be that it's beneficial to have the things be in contact over more area

[–]imgonnacallyouretard 1 point2 points ago

The red gear can really spin the shit out of the green one(torque), and it makes the spin happen at a different angle.

i hate how it skips.

[–]edeo2011[S] 1 point2 points ago

If you click on it, to enlarge it, it doesn't skip anymore. enjoy :)

Even engineering porn should be marked NSFW.

[–]dravinicus 1 point2 points ago

Yeah your imagine can run wild, then forget what you were doing.

[–]the32ndpie 1 point2 points ago

Holy crap for the math involved in designing that, and making this gif. And if special programming tools were used to make that simple, holy crap for the math to make those tools... holy crap

[–]portalsoflight 0 points1 point ago

That was so cool that I had to catch my breathe after I first saw it.

[–]Hoveringmouse 0 points1 point ago

What has my poor brain ever done to you?!?

[–]Hyperdrunk 0 points1 point ago

It works because of reasons.

[–]RobotRX 0 points1 point ago

Beautiful
