[@jamessturgeon7025]

That is a REALLY good and very thorough explanation of very useful technique! It’s a little difficult to understand some of the audio...maybe get rid of the music background, but this is worth multiple viewings to get all of the little technique details which are in there. Thanks!

[@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 (or you might not, but the surface contact will be off anyway). I suppose the correct way to model a worm gear would be here (it's a helical spur gear): kzbin.info/www/bejne/p4OlfaN4rdCfmsU

[@popzct]

You did not explain how you translated the "ISO Metric Trapezoidal Threads" linear spacing to the rotary spacing of the circumference of the rotatory gear you present in order to achieve a pure rotary thread spacing. Although your presentation is helpful, it is not applicable to universal worm gear design since there's more math involved than provided in your presentation.

[@Fusion360NewbiesPlus]

If I understand your question correctly, then it's very easy. In order to match the movement, you need to know the ratio between them. You can use this website as well: geargenerator.com/#200,200,100,6,1,0,0,4,1,8,2,4,27,-90,0,0,16,4,4,27,-60,1,1,12,1,12,20,-60,2,0,60,5,12,20,0,0,0,2,-563

[@bmotik]

The way you just eyeballed how much you have to move the worm gear is just not precise way to do it. There must be a way to make this snap exactly where it needs to be.

[@leifbeaton8286]

I'm pretty quick on the uptake, and I did enjoy the video, but allow me a moment of constructive criticism...The IMPORTANT parts, the actual construction, menu options, et cetera, you went through as a Duracell bunny on hard methamphetamine. The utterly insignificant elements, bevels and chamfers, you slowed down to a geriatric who had glue for breakfast. May I humbly suggest reversing the tempo choices?

[@leifbeaton8286]

(secondary note - the second gear will have an incorrect tooth profile in relation to the worm, which will increase wear and backlash, but it is more than good enough for my current purpose. So thanks!)

[@Fusion360NewbiesPlus]

Thanks for the tips!

[@Fusion360NewbiesPlus]

If you watch a few more of my videos, you will quickly understand that my videos are about techniques and how to work with F360. I leave the engineering to the engineers! 😉

[@leifbeaton8286]

Perfectly onboard with that, although the technique for creating the meshing gear for the worm could arguably be within the definition of how to work with Fusion 360. That being said, and as I said, this method is "close enough" for me. I am constructing gears for a 3D printed assembly, and my FDM 3D printer has nowhere hear the tolerances that the "cheating" on the mesh gear will matter. Nor will the introduced backlash matter one bit. In fairness, I suspect that most people seeking out this video will either be looking to create parts for 3D printing, or simply for animation, and for those people too this method will be more than adequate. Throwing in a disclaimer in the video or in the description about the accuracy of the resulting gears might save you the hassle of comments like mine, and a few others down the thread... In summary, this video saved me having to seek out a finished component made by someone else, likely meaning I would have to design around an already decided upon gear ratio and awkward dimensions. So, thanks for the guidance - but slow down a bit, Chief. :)

[@allyourcode]

I really do not understand why this results in gears that mesh correctly. Yes, at the one position where you cut, the two gears do not intersect, but I do not see why that would be true at other phases of rotation. Seems to me, you need a whole bunch of cuts, one for each point as the worm travels "around" the other gear. The only way this would work is if the intersection of the blank disk with the worm at other phases is always contained within the intersection at the "top dead center" phase. Is that true?? Also, I do not understand where the number of teeth came from :/

[@Fusion360NewbiesPlus]

In regards to the number of teeth, please watch this video: kzbin.info/www/bejne/fqich5-MbMqhodU In regards to why the gears are mesh correctly, is simply because the profile of the worm tooth and copy it (subtract it from the gear) to the gear. This way both sides are identical!

[@johnfurr8779]

Thanks. Just one comment and one question. The volume was very low, despite having my fully turned up fully I could barely hear you. Secondly, is there a formula for adjusting the angle to get the two gears to sync in rotation based on the number of teeth in the helical gear and the teeth per inch on the worm drive? I can't seem to get it to work well in the animation. Perhaps because I was using 60 teeth in a relatively small diameter?

[@Fusion360NewbiesPlus]

Hi John, Thanks for your feedback. Regarding the volume, my apologies! This video is from my early time and I guess I was a little shy ;-) Second, regarding the sync between gears - It is a very simple formula. I'll tell you how to do that, but first, I'm gonna need your help. It doesn't take a long time and if you will help me, I'll even make a special video for you :) What say you?

[@Fusion360NewbiesPlus]

Don't forget to watch this video as well! kzbin.info/www/bejne/jIacpHVsp76lqtE

[@Oggies100]

Thanks for a great videoIs it possible to drive the gear via contact/set if you didn't know the ratio? I.e. The 15 degrees

[@Fusion360NewbiesPlus]

It is possible, but it's not recommended! since Contact Set takes A LOT of CPU resource.

[@w02190219]

Very nice

[@hidgik]

Wonderful! Thank you! Is it necessary to check for collision detection or it is not?

[@Fusion360NewbiesPlus]

Hi There, The friction element is very important, but it depends a lot on how you expect the application (your model) to work and behave. Which is why for example, if you look at Bolts & Nuts dimension tables, you will see Pitch diameter Min. & Max. - the question is, How tight you want/need the Worm gear to be!? Now, to answer this question you'll need to things, 1. Experience and/or 2. Trial and error. I hope I answered you question :)

[@ekremtok1192]

Thank's for the sample.

[@akshayd211]

[@isaiasramirez2909]

how do you determine the number of teeth?

This is a really good question.

[@DigiteoPL]

@@Fusion360NewbiesPlus hmm but in this table in "to find" row there is no "number of teeths"... Thread that you use is TR30x10, i found PDF and max pitch dia is 24.850, and i still dont know what is rule to calculate number of teeths if i know diameter of wheel :D

[@goddamnmaddog2024]

@@DigiteoPL I think for dimensioning the outside diameter gets calculated by the number of teeth, not the other way around. You know the force that gets transmitted, this gives you the module. You should know the ratio that you need. That gives you the number of teeth. You know the wheel will move for one tooth if the worm gear makes one whole turn. From here you can use Formula for Outside diameter. But notice more important is the pitch diameter for positioning the profile of the tooth. If you want to make gears, try to understand module, it's a bit tricky but once you get it, it's so easy.

[@Crazymakers]

HI friend. How did you find 24 teeth without any formula please ?

[@Fusion360NewbiesPlus]

Here you go, this should help: kzbin.info/www/bejne/fqich5-MbMqhodU

[@fardouk]

Nice but how did you determine the diameter of your gear ?

[@Fusion360NewbiesPlus]

That's a good question! As I remember, I manually added more teeth until I got the right amount. But, there are websites that can do the calculation for you like this one: www.otvinta.com/calculators.html

[@trickygaming773]

how did you know the gear needed 24 teeth? or what diameter to use

[@brooksrussell5695]

Determine the distance between 2 adjacent teeth on the worm (helical) using points at the middle of the tooth at the high point. Multiply that value by the amount of teeth you desire to find the circumference of the larger gear or divide the circumferance of the of the larger gear blank to determine number of teeth. If the number of teeth is not a whole number you then must adjust the circumference until it is or the teeth will not match. C=2(3.14)R

[@neilfpv]

I'm back for a question. My trapezoidal thread looks a little different from what I saw in your youtube. It's a little fat. It's also ISO Metric Trapezoidal Threads. The number of teeth I used was 32 when I was creating the circular pattern. When I tried the value of 24, it was far and not aligned. So I tried driving the joints and after few degrees, the thread and gear weren't aligned anymore. Here is a screenshot - i.imgur.com/jgPfSPs.png Any ideas where I did wrong?

Most of these "How to create [spur; helical; worm; inner; so on...] gears" lessons are not parametrized, and are quite unusable. You guys crate something looks like the selected gear, but with totally random parameters. The gears has standardized parameters, for example module, pressure angle, helix angle, addendum, dedendum, pitch circle ... so on. And this is the most important part, not drawing a spiral or cut-combining components. And the purpose of CAD programs is creating something that is working and manufacturable, 3D-printable, millable, turnable, castable. What can anyone do with the above design? Honestly ?
