3D printed worm gears designed in Fusion 360

Worm Gears has few advantages compared to spur gears, but so far, there is no automatic tool in Fusion 360 to add worm drive to our design. For spur gears we can use ADD-IN SCRIPT and those gears can be part of our design with only few clicks. In this video I show step-by-step tutorial how to design a worm gears (worm screw and wheel) in Autodesk Fusion 360. At the end of video, I 3D printed and tested it.
This method is not perfect, probably printed worm screw or wheel cannot be used with standard gears, but if we 3D print both parts, they can work together without problems. I noticed that these 3D printed gears are much noisier compared to spur gears.

Best video about worm gears on youtube. Thanks for sharing.

[@makers_lab]

Thanks for this. As a design refinement, worm wheels also tend to have an indent around the middle of the teeth so the worm can sit lower, but nice to see it's not essential. Another vid on 3d printed worms also shows that applying grease reduces wear substantially (they seemed to have none vs destroyed gears without) so a good idea to use that for high speed / extended use.

[@InfinityMW2]

Straight to the point, simple to understand, Hope to see more in the future!

[@shaunstewart4064]

Absolutely brilliant. I have been looking for a solution to this issue for ages. Thank you.

[@santiagoblandon3022]

I've been looking for months how to do this. Thank you!

[@SuperKingslaw]

Wonderful tutorial! Thank You!. This seems a natural for mounting and use with small stepper motors. Thanks again!

[@JimK0QJC]

Excellent. I am using Fusion in Middle School. Many good techniques in this video.

[@michaelwhisman2479]

Nice. For some reason, I felt I could not 3D print a worm gear. Looks great, can't wait to make one myself now and possibly not need an outside manufacturer.

[@danielbilodeau4701]

beautiful video, thank you

[@Patyx42]

Fantastic video, subscribed!

[@JeffBradway]

You might want to try creating an intersection body between your worm and wheel to start. Then indexing that body in a circular patter 1 tooth at a time and performing a cut operation. I think this will give you a closer appoximation of the involute surface on your wheel and might help with noise.

[@paweprzybysz7505]

Thanks for great tutorial. I found today an util named GF Gear Generator that should speed up the design process. I don't understand all the parameters of the plugin yet but I hope to make a worm gear with this method. I hope my comment will be helpful in the topic.

[@CoolStuff1]

Thank you just what I needed.

[@rahulajayan5546]

[@didiercarne1935]

Merci, super boulot, cette vidéo m'a été d'une très grande aide, Thanks, this video helped me a lot

[@petleh82]

I just found your channel, looks very interesting so of course i subscribed. I used to do worm gears manually like you but i found much better way. I bought a plugin called "worm mesh maker", in the fusion 360 plugin store.. it was $20 but i think it was well worth it, now it is as easy to make wormgears as it is to make regular spur gears..

[@MyTechFun]

Thanks, good to know, $20 is not much if you use it often. So far I need worm gears two times since I have 3D printer.

[@WistrelChianti]

Good info!

[@stormq8]

[@MyTechFun]

Yeah, maybe, YT has strange algorithms nowadays. But thx for motivational comment!

[@logitech4873]

Thanks for the guide!

[@MrVein5.0]

good tutorial. even tho, first time i followed, the big gear would do as in your video when resizing the circle, the next time i could not get the outer diameter to be the fix point but i just used 2 point circle instead and made the diameter the right one from the start.

[@ismailyuncu8672]

Thank you my thick haired friend, good job :)))

[@rampak1]

Superb video. To reduce noise I like to use a short belt drive for a first-stage reduction between the motor and the worm.

[@MyTechFun]

That's good idea too, I planned to use a spur gears.

[@filmogosc]

@@MyTechFun on belt maximum ratio will be about 1:5, but definitely worth it, spur gears will be loud as hell too :D

[@womacko]

Very nice show down on this topic! Can you explain how to to it the other way around? In my case, I have a gear and want to design a worm for it.

Igor, I kinda want to show you a project that I've been working on. This is the second video I've seen of yours with very special overlap. You would definitely like it.

[@MyTechFun]

You can find my contact email if you need to on "About" page of the channel. kzbin.info/door/6QckhILSqdl3K0TWPWrDdgabout

[@WoLpH]

Why do you need to remove the other cut-outs from the worm gear? The proper cut would go beyond those partial cut-outs so they should automatically disappear, right?

[@donaldlang9157]

Thank you Igor for sharing your expertise. Do you have a patreon?

[@MyTechFun]

I am happy that you like my work, there will be more.. Yes, few weeks ago I created patreon: www.patreon.com/mytechfun

[@hathzorz]

Hey Igor, it looks like there's a Fusion 360 add-in called GF Gear Generator that includes worm gears. I haven't tested it out myself yet, though.

[@MyTechFun]

[Edited comment] I tested it with worm gears, worm wheel is not generated correctly. It looks like a spur or a helical gear, not worm wheel.

[@hathzorz]

@@MyTechFun thanks for testing! Great to know.

[@wiltherdelacuesta8175]

Very nice! I have a question, can you make turn the wheel by hand so the motor-shaft turn around too?

[@MyTechFun]

Yes, it is possible, but you need much bigger pitch angle.

[@wiltherdelacuesta8175]

@@MyTechFun ohh nice, the pitch angle, that is the secrect, than you very much...

[@rahmanmahmud2566]

Thank you for your video. Does your gear have backlash? I need some worm gears of zero backlash. Can you suggest where to find it?

[@MyTechFun]

They have backlash. For spur gears there are a lot of solution for zero backlash (like double gear with spring load etc), but I don't have experience with worm gears (in this topic).

[@rahmanmahmud2566]

@@MyTechFun Thank you so much for your reply. I really appreciate it.

[@neilfpv]

I will try it tonight! Question, what made you pick 60 for the number of teeth? Was there any formula that you used? Thank you!

[@MyTechFun]

I needed 1:60 ratio. Depend of your project, what ratio do you need..

[@neilfpv]

@@MyTechFun Got it! Thank you.

[@HuFlungDung2]

Your attempt is a good beginning, but it's not all the steps required. A worm wheel tooth also needs an involute relief to the tooth face. You can generate this by rotating the worm around the model and recutting the tooth. You have to keep the worm timed in rotation around the wheel. So if you rotate the worm model 5 degrees around the wheel model, you have to rotate the worm around its own axis by the same amount. Do this about 4 or 5 times, and you will generate a decent tooth space. Each repeated cutter operation creates a new facet on the face of the tooth. So the final model will exhibit 4 or 5 tiny slivers of surfaces, each contributing to an involute curve combined with a helical path. I would focus on getting one tooth formed correctly, as this process is quite tedious. Then copy/ rotate as many as you need to make the entire wheel. You section analysis fails to detect interference off the center plane. I'm a real life machinist and have cut worm wheels with a ball nose endmill using a model generated as i described. Even then, my model is only a reasonable facimile of a worm wheel. But it will actually go together at the correct center distance, whereas, yours will not mesh without interfering.

[@emrage]

Is there a better video out there for designing of worm gears?

[@ToddChevrier]

Herringbone

[@osmanpasha_diy]

Subtracting a worm from a worm gear is incorrect. When the gear rotates, it encounters the worm at different axial offsets that subtraction did not account for. You might notice interference if you rotate the worm and gear a bit. I suppose the correct way to model a worm gear would be here (it's a helical spur gear): kzbin.info/www/bejne/p4OlfaN4rdCfmsU

[@hans6458]

Great Video. Isn't there a mistake how he's creating the lines for the pitch-diameter? According to that video (kzbin.info/www/bejne/Z2OupK2tat5lg8U) the lines shouldn't be placed in the middle of the flanks..

[@MyTechFun]

That's right, good perception (but it's close), and as I mentioned, this is not standard worm, it can not be combined with commercial worms, it will work only if you design and 3D print both parts (screw and wheel).
