3D Printed Gearbox (Herringbone Gears) - Speed Test

I want to see something like this but in a fully enclosed see thru case with gear oil so it's constantly lubricated and we can see it throwing the oil around... best choice may be automotive gear oil ( 80w-90 )

I swear Every comment has… Read more

Ha each gear will have 2 bearings press fit, begins hitting it with a hammer.

For gear lash a mm difference is too big, try increasing it from 75 to 76 by .1mm increments until the teeth mesh best, also enclose the box and allow the bottom teeth to sit in oil.

So, would this be strong enough to start an electric plane if there was a motor?

I can't be the only one that read Herobrine gear.

Use a torque wrench

bro just skip to the part where it breaks because its plastic spinning at the speed of light

Steel

That’s well

You know what you’re so mean to press the right

Is it copper

Se desconsiderar a resistência do ar, o atrito, a resistência mecânica dos materiais, a perda por calor e a física quântica, a última roda dentada pode chegar na velocidade da luz.

You should extend the whole thing to be a meter long

Can I put something like this in a bike and go crazy fast?

Now use 300 gears and race a supra

try using ceramic wet lube

"press fit bearings" as you are hitting it with a hammer... lol

What? Can't 3d print bearings?

So... how many rpm per minute on the last gear? You got the math somewhere? Or maybe try measuring it somehow?

Ohh nvm it already had it

tbh i just wanted to see you spin it so i skipped half the vid

Mathematics

what about a 0.5mm reduction in the axle spacing to interlock the teeth more so they are less likely to slip

rrrrr

Make with iron

I had a similar idia but I tried it on my bike and it didn't work

Watched this vid 3 times over, and speaking as a Technician i can say you got most of the major issues out of the way. Now you main issue with the gears gripping and skipping comes down to accuracy and alignment.
Since the gears are filament "printed" there WILL be some deflection and warping as they cool. So as with most parts I'd suggest giving the sides a very light grind so they are more parallel to each other and once they are, Bore out the hole for the bearings so it will be at a 90 degree angle to the sides, this should reduce your vibrations and make the gears run better as there will be less deflection while spinning on the axel.

I think its funny to use mtb dry chain lube for a project like this.

Not him putting the airport jungle juice on the gears

Cool

why did you put dry lube and continue to use it before it dried... WTF

use this gears and make free electricity

Connect it to a Generator

Try high spin low torque Tesla turbine at other end to run generator

put a Dc moter at the end

This thing is literally about to explode.

Invasive thoughts: What if you submerge it in oil? and then take it out asnd run it?

Why cant we just do that to generate electricity?

make the gears in the shape 90 degree and metal I would test in plastic first/3D print

wait a minute did those gears just coom?

make the handle more heavy then the thing and tada better spin

if those are 'smooth rods' like the ones on some 3d printer they are VERY hard, they are a bearing wear surface and typically are hardened after precision grinding and then plated with something even harder, normally chromium. im sure you smoked quite a few bits drilling that bit hats off to the persistence, if you need to drill very hard materials in the future look for carbide tooling.

I would add 2 special gears to facilitate a midpoint brace so you don't have that gear hop/skip on the center section

the meaning of this song is
to tell about the feelings of
       someone who first fell in love.
This feeling also made him  
   a different person and often
asked about the feelings of
                 the opposite sex through the lyrics.

See how much electricity it makes
