Great video. The pace in the tutorial is good. I like it that you hardly, or even do not, use keyboard shortcuts, which a lot of tutorials on YT do and is often hard to follow. This is really important for a newby like me. Also the explanation of how worm gears work with the ratio is very much appreciated.
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.
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..
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.
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.
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.
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.
that thing that the worm gear can turn the spur gear but the spur gear cant turn the worm gear can help if you want to make a one way sort of mechanism so not a disadventage in my opinion
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.
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.
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).
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?
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): th-cam.com/video/qRBLpBxkldc/w-d-xo.html
Great Video. Isn't there a mistake how he's creating the lines for the pitch-diameter? According to that video (th-cam.com/video/12Kszw5y2Mc/w-d-xo.html) the lines shouldn't be placed in the middle of the flanks..
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).
Good video the worm wheel geometry is weird and has a more open shape because of the spinning of the worm and wheel. This means the method of modeling you are doing is not the exact form of worm wheel. This is just a FYI for the viewers. I am still trying to figure out how to model a closer form of the worm wheel.
Best video about worm gears on youtube. Thanks for sharing.
Straight to the point, simple to understand, Hope to see more in the future!
by far the best tutorial I found on YT about thins. Thanks you very much

Fantastic explanation of how to model the gears in fusion
Absolutely brilliant. I have been looking for a solution to this issue for ages. Thank you.
I've been looking for months how to do this. Thank you!
Excellent. I am using Fusion in Middle School. Many good techniques in this video.
Wonderful tutorial! Thank You!. This seems a natural for mounting and use with small stepper motors. Thanks again!

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.
Good info!

What I was looking for! Thank you sir.
Great job dude. Absolutely GREAT!
Thanks for the video. This will be very helpful for when I need to create a worm drive.
Superb video.
To reduce noise I like to use a short belt drive for a first-stage reduction between the motor and the worm.
That's good idea too, I planned to use a spur gears.
@@MyTechFun on belt maximum ratio will be about 1:5, but definitely worth it, spur gears will be loud as hell too :D
Great video! The design part was really clear and helpful.

Thank you just what I needed.
Great update/design 👍
Thanks for sharing 👍😀
thank you for your work , your detailed and very clear explanations
its me again! thank you! this is so interesting

Thank you very much for this one! It will come really useful in one of my next projects.
Great video! Thanks a lot for sharing this video. Great explanation as always.
Wow very professional video!!!! Very informative!
My needle nose pliers also tighten hex nuts on a regular basis ;)
The video is so helpful. Thank you
Really excellent tutorial, and very practical, like all your videos. Many thanks for all the information you put up!

Wow, many thanks
great video thanks!
thank you very much its very helpfull
Thanks, interesting technique!
Brilliant!! Thanks alot
make a video on cycloid drives
Heisenberg, is that you? Now making mechanisms, but still blue)))
Very nice!
I have a question, can you make turn the wheel by hand so the motor-shaft turn around too?
Yes, it is possible, but you need much bigger pitch angle.
@@MyTechFun ohh nice, the pitch angle, that is the secrect, than you very much...
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.
Super, j'ai beaucoup appris. Merci à vous
Thank you very much ! ^-^
oh thank you

@@MyTechFun Thank you so much for your reply. I really appreciate it.
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!
I needed 1:60 ratio. Depend of your project, what ratio do you need..
@@MyTechFun Got it! Thank you.
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.
[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.
@@MyTechFun thanks for testing! Great to know.
Super

i want 3d printing machine where could i buy the machine what is the payment conditions i am from india please suggest me how to get the machine
One of the most popular budget printer is Creality Ender 3. I own Prusa MK3, but it is 3x expensive.
OK sir I want to buy the machine how can I buy tell me
