GF Gear Generator: apps.autodesk.com/FUSION/en/D...
In this video I show you how to design gears in fusion 360 easily. Most of the time people will start from scratch but the truth is that you really don't have to. The Fusion 360 App store features a lot of fantastic scripts/add-ins that can tremendously speed up your workflow. In this particular example, I demonstrate how GF gear generator can be used to create a dual helical gear in a matter of seconds. I hope you find this useful for your own projects.

if you'd like to calculate the correct distance to move your 2nd gear, you can use this formula:
(M*(T1+T2)) / 2)
(Module * (Number of Teeth in 1st Gear + Number of Teeth in 2nd gear)) / 2
Do be aware that 3D printing has wider tolerances than typical machining, so you might have to try a few prints at +/-0.25mm
How would you suggest integrating those +/- 0.25mm toleranzes? Is that configuratable when creating the gears or do you manage that later in slicer? Changing the values in the slicer would probably change the values of all the other dimensions tho...
@@benloschnigg9275 I would add a small gap in fusion 360 with a user parameter to adjust and try printing with different tolerances
@@wizardOfRobots I’ll try that :) thx
@@wizardOfRobots what do you mean? a settting in cura?
You can reduce wear on the teeth when you choose odd ratio. 50 to 10 same teeth will meet every 5 rotations. 49 to 10 or 50 to 11 it takes many more rotations before same teeth meet and make wear more even.
Is that actually researched and proved to be a good thing? Now instead of one tooth having to mate with 5 teeth, it has to mate with 50 teeth so any imperfections of one tooth wear every tooth of the other gear down.
@@snarkygnome619 Yes it's proven. Every continuous turning gearbox for every thinkable use, except maybe mechanical clocks, have odd ratio's, allways. Since the invention of gears. You can Google for gearratio's of gearboxes of cars for example.
Which gearbox will fail sooner, the one where two teeth wear each other out, or the one where the wear is spread over several teeth.
@@erwinritter4067 Thanks! Learned something new!
This is really nice. Trying to do bevel gears and worm drives without the addon you mentioned becomes very difficult. Fantastic video as always. Keep the CAD coming.
Very helpful, thank you!
Putting holes in the gear doesn’t actually reduce the weight, if you don’t Print at high infill, it just adds more surface area and the print will take longer and use more material
Just downloaded the the Fusion 360 GF Gear generator ! Awsome ! Thank you .
This is very helpful, thank you!
Thanks for that tip with the add-in GF Gear Generator ;)
Thank you for this awesome video, it really blessed my current 3D print project.
Awesome Video, making gears is now so easy👍
came here via YT recomendation , glad that I did because this is what i was looking for. Thank you for this great video !
Glad I could be of help. Thanks for watching!
awesome vid and just the F360 info I was looking for 😁
SUBSCRIBED! THANK YOU!
the disocrd at 3:21 really got me XD I was looking around in all my servers like "WHOMST HAS AWOKEN THE ANCIENT ONE"
Lmao same
Great Video!
One question, is it possible when you make a drawing from a gear for manufacture, can the gear data be outputed? Like, Number of teeth, pressure angle, helix angle, Quality, toothwidth over x teeth, and all the other stuff for manufacturing?
Thank you very much. You helped me a lot!!!!!!!!!!!
don't you have to add some margin for 3D printing as these will be too tight for the meshing? If so, what margin do you take?
Nice vid, thanks!
superb thanx big brother
this is great! how do you judge shaft distance for good meshing?
Thank You
Very nice!
Excellent! :D
Pressure angle is 20 deg according to ISO standard. For the smaller gear typically number of teeth is not less than 16.
great vid
First of all thanks for this tutorial!
Can I use the GEAR GENERATOR add-in with the browser version of Fusion360?
How do you go back and edit the gear. When you try and edit, it doesn't open the original window where you selected the Module/Teeth/Height. It brakes it down. How do you get those settings to pop back up so you can edit it. For example let's say I selected 15 teeth and I want 20 instead. Is where an easy way. To me the easiest way would be the original Spur gear window to open where you can change those settings.??? Thanks for your help.
Sorry if this question sounds dumb...but how would one find the tooth module size (in mm of course) of a gear/belt in real life? For example, I have some GT2 belt lying around from my 3D printers. I know it is 6mm wide, and the internet says it has a 2mm pitch. Does the pitch = tooth size here?
I'm not sure if those holes always add weight reduction, depending on the infill. The walls of the holes might be heavier than what the infill would have been.
Very true. Weight reduction depends on multiple factors
Thanks for sharing 👍🏻 Based on your experience, what would be the minimum layer height for these gears to work well? Your car looks cool by the way!
Hi Mickael, I printed my gears at 0.2mm to save time and performance was still good! A lower height will probably add strength but I can't say how much, that'd be a good test!
@@thehardwareguy Thanks for the quick reply 👍🏻
why did you skipped this part tho? pretty important point 6:59 how do you position the gear right? one is easy but how is it if you want to build a gear box with multiple gears?
You usually have one part file (like the one he is showing) for every gear. Then you start a new assembly file and import all the gears into the assembly. It is much easier to position different objects to one another in an assembly file.
Nice :-)
Do uou know if you can make inner gears with this too? Like for example when used on planetary gear boxes where for some gears the teeth are on the inside
same q. did you find out or anyone else?
Its better to use teeth counts without common dividers. Or you can just use simple numbers.
For you example it should be 13 and 61 teeth, give us 4.6923 ratio
Thank you for making these video's they are very much appreciated by someone my age. I download the GF gear generator on my Mac. But I have tried unsuccessfully to find out where it goes, when I open up Fusion 360 it doesn't appear to be there either. Any help would be great help.
Thank You. PLEASE Stay safe
download and make sure to install it. Then look for it in the "Tools" section on the top
Hey, did you solve the problem? There is a Mac OS version to download, so make sure you click on that (it should be highlighted) before downloading. I don't have a Mac to give much help beyond that. Hopefully the rest of the setup is the same as this video. 👍
I have a similar issue, were you able to resolve it ? Other addins show up fine , I face a problem with this one only
Can you use this script with the free version?
When I try and create the second gear, it appears at the same location as the first one, how do you get yours to appear next to the original one. Mine all appear at the same origine. I noticed that your new parts/components appear further away next to the part. Mine are inside of each other. It's annoying, I did everything the same you did on the video. So it must be a settings or something you forgot to mention. Please help and thank you for your great videos.
New gears will always place themselves at the origin. Convert the gear body to a component like I showed in the video, and then you just move it using the move tool
Who else checked their Discord at 3:22
Ok.... so for people who are trying, like me, to re-create an EXISTING gear, take a caliper and measure the outer diameter of the teeth (pitch diameter) in MM, then divide that by the number of teeth, itll give you your gear module. Now you can recreate it with this.
how do you get the tooth height though?
How do you determine the radius of the gear?
Typically you don't because the radius/diameter is determined by the module and the number of teeth. Adjust those parameters until you get a radius close to what you want
Hello. Not sure if anyone will answer this...I have watched two videos and yes this is a nice feature. However, if I have specific plane and location that I want the gear to go, how do I accomplish this? I have tried multiple times and cannot seem to do this. It keeps locking into the origin. I have tried different move commands, I have tried selecting the plane, etc. Nothing works.
You should always design your parts at the origin and use joints to position them afterward!
@@thehardwareguy Hi there. Thanks for the reply. I am somewhat fairly new still. I thought I had, but for some reason it not. Is there absolutely no way to place the gear specifically where one wants it other than the origin? I have no idea how to do this. I have moved objects before successfully. I just need detailed advice on how to do this.
I looked into it more and I will try to educate myself on joints. If I need additional help I will ask, if you are willing to help :)
@@thehardwareguy Looks like I figured it out. It was not that hard once I knew what I was doing. Thank you! :)
🔥💕👍
I converted it to a component then created the new one and it appeared inside my first part. I don't see you converting anything, you just create a second gear and it appears next to the original. Mine keeps appearing inside the first one. Something is missing here??? yes, later in the video you convert to component, but I didn't see that earlier in the video when you first creat the 50 gear with 40%. It just appears next to the other one. You don't convert to component until you created the small gear and you move it next to the other one. Obviously I'm confused now.
Create a gear, move it, and then create the second gear. That should solve your issue👍🏻 you don’t have to convert to a component, but it’s good practice! You can move bodies in the exact same way
@@thehardwareguy Thank you, I will do that. The video just confused me, in the video you don't show converting to a component on the first gear, you just dragged it to the left and then created a new one next to it. I tried that and the other one just appeared in the middle of the first. That's why I was confused. You must of converted the first one to a componnent before moving it, it just didn't show that in the video. So I will do that. Now if I may ask, how did you mate the two together, the small gear and the big gear. If I just move mine over, it doesn't exactly mate properly (aligne). Is there a trick that you didn't show in the video? Thank you for your time, I really appreciate it. Your videos are awsome, Just not always friendly to new people like me. Thank you.
@@NarcosisJunky2 That part freaks me out right now :) I am desperately trying to mate the gears, in order to put some axis through it an turn them to something useful, but in this exact moment, where the gears are nearing the video skips the decisive second.
@@holgerheinrich2992 yesssssss i have the exact same problem!!! an other guy used another plugin where you can read the pitch diameter. then he does it like this: (gear 1 pitch dia./2) + (gear 2 ptich dia. /2). but i cant figure out what the ptich diameter is!
@@NarcosisJunky2 used another tool: th-cam.com/video/zamc_PCBvOA/w-d-xo.html&ab_channel=Let%27sPrint
How do i change diameter of gears?
You can change the diameter by adjusting the number of teeth and module
@@thehardwareguy soo there isn any way to make gear that will have exact diameter that i want?
They are not true involute gear forms i.e no dedendum form?
Beginner here, how do I make the gears bigger, say the gear diameter i want to make it 10 times bigger
Bigger gears can be achieved by Increasing the module
@@thehardwareguy thanks forgot what module was >
thumbed
Caution with this add in. If you know what you are doing you cannot use it, if you do not know what you are doing you might run into problems 🙂
This doesn't work in inches. It gives me a massive gear even when I have the pitch set to 25mills and 17 teeth.
In my opinion, the MOST important parameter is total diameter. The gear is completely useless if it can't fit into my gearbox. Trying to get an imprecise approximate diameter through trial and error by spending hours on a single fucking gear is the height of stupidity. I just want a single program that asks me what I want the total diameter to be, and then it designs the rest of the parameters I input around that critical value. It would literally take less than 5 minutes rather than taking over half a fucking day to make a gear the "normal" way. Humans are stupid sometimes.
I'm going to use this software to make me a girlfriend!
mate why did you cut the most important thing out. MOVING THE GEAR!!!!!. Im sorry its a great video but this simply freaks me out.
Thought it was pretty self explanatory to be honest! You move it the same way you move anything else in Fusion 360... The Move Tool
@@thehardwareguy and how the heck are you supposed to get the exact distance? This is so important! I used another tool where i get displayed the pitch diameter. With this value i can calculate how much i need to offset the gear.
You can use this formula: (M*(T1+T2)) / 2)
(Module * (Number of Teeth in 1st Gear + Number of Teeth in 2nd gear)) / 2
@@thehardwareguy finally thank you, but this would have been important in the tutorial
