HI, I used INVENTOR in 2019 to 2021 at Uni. I tried to make the gears for an internal ring gear to mesh with a spur gear. What a nighmare. I even tried to get the experts at Inventor to help with this and no one could help me. This was an awesome video. Thanks.
Gear Diameter: Modules = Desired Diameter / Teeth Mesh Properly: Modules must be the same Position Equation: (M*(T1+T2))/2 (Modules*(Teeth1+Teeth2))/2 Angle Teeth: 360/Teeth/2
im running into an issue. i have to make a gear that is smoth on one side while the other has 9 teeth with an outside diameter of 32mm. i made a gear using 32/18 module, than made a half tube 16mm radius to cut the unwanted teeth off... the gear does not have a radius of 32... its larger than my half circle, what's wrong?
Short and simple, thank you. I was apparently blind that i did not see the making up a gear button and now a little bit ashamed to say that i wasted my time with a cylinder and cubes.. until i just thought there must be a much simpler way in a cad program.... pff.. :)
0:45 for anybody out there trying to get their outer diameter to be exact, the given formula in the video isn't correct. the formula for outer diameter is: OD = module * num_teeth + 2 * module solving for module this gives: m = OD / (num_teeth + 2) hope this helps anyone wondering why their OD isn't as expected using the formula in the video.
Yes, you are correct. Maybe I should've been more clear in my video, the diameter I was talking about was the gear pitch diameter. This equation is good to know when wanting a specific gear ratio and a have set distance between two shafts.
@@TabletopRobotics The rest of the video was super helpful, I'm just new to this and my gear wasn't the right size so I had to do some digging and left a comment in case anybody else had the same issue.
This is also an interesting question... I was kinda thinking to extract from a rectangular shape and just copy it next to each other, but if there's a simpler way to do it, i would like to hear... :)
Maybe I'm doing something wrong, but I don't get true involutes on a gear designed in FreeCad, but just straight lines - so the gears would not mesh correctly. Is it possible that this Gear-Design is just a rough approximation or am I missing a parameter ?
Thanks , good video. A little fast for me at times but I just paused , went back and rewatched til I understood what you did. I'm older and hearing isn't as great anymore. I had some trouble with the part where you divided th gear diameter by the number of teeth. It didn't work for me. I have a gear with a 36mm diameter with 13 teeth.
One small problem for some. There are MANY people with poor eye site. We can not follow small and very fast pointers. At times they just disapear. Could you help us and make the pointer bigger. White pointers with a black edge works very well when they are bigger. Thank You,
I need to 3D print a gear that is out of production for a lathe. I’m new to CAD in all senses so I’m trying to follow along but when I select [Cut of Two Parts] it stops working. I just installed V. 0.20 how can I get past this point? I also need to use US standard units for this gear: involute instead of Modulus, how can I change this?
seems to me the number of teeth is dependent. We must get paper and pencil and multiply by pi divide the pitch!!?? Im not that smart. Then it does not come out even!! ...oh i got it go backwards.
One of the best freecad tutorials I have ever watched. Thank you.
...and now I've found my first FreeCAD tutorial video, and this CAD parametric design thing is starting to make sense. Thanks!
yeap, this is my startig tutorial too
HI,

What a nighmare.
I even tried to get the experts at Inventor to help with this and no one could help me.
This was an awesome video.
Thanks.
Thank you. It was easy to do it with your explanation. I learned gears in FreeCAD but also understood how to calculate gears.
Very nice video. Thank you for taking your time to explain in a clear and comprehensible manner.
WOW. thanks. I have tried doing gears manually but it is really easy when you do it the right way! Thanks!!!
Appreciate the excellent step-by-step build of the involuteGear
Thanks a lot for making this quick and simple tutorial. It helped a lot!
Thanks for this.
I had lots of fun, following along - on my very first ever use of this cool CAD software.
Gear Diameter:
Modules = Desired Diameter / Teeth
Mesh Properly:
Modules must be the same
Position Equation: (M*(T1+T2))/2
(Modules*(Teeth1+Teeth2))/2
Angle Teeth:
360/Teeth/2
Thanks a lot man!

Another great video. Short and to the point - thanks!
I greatly appreciate this tutorial. Thank you!

Clear and concise, very easy to follow. Thanks ;)
Finally, a video that matches my laptop screen, thanks
0:45 for anybody out there trying to get their outer diameter to be exact, the given formula in the video isn't correct.
the formula for outer diameter is:
OD = module * num_teeth + 2 * module
solving for module this gives:
m = OD / (num_teeth + 2)
hope this helps anyone wondering why their OD isn't as expected using the formula in the video.

This really helped thank you. One doubt how do you animate it
thanks a lot that's what I was looking for, great job!
Awesome job. Now how do you make the rail with teeth for the gear?
This is also an interesting question...

White pointers with a black edge works very well when they are bigger.
Thank You,
Thank you for your feedback and yes, I will make my pointer more visible in future videos.
@@TabletopRobotics Thanks a LOT. 👍
Nicely done! It helped a lot
well you got my thumbs up coz i didn't know how to make gears on freecad.
super smart dude :)
Thanks for the tutorial mate!
Excellent tutorial! Thanks brother.
Of course we like it !Thank you !
Very nice
Thank you thank you thank you! The gear on a discontinued product I want to keep using broke and I think I may be able to get a replacement now!
thank you for the video very helpful
Thanks. Any idea on how to make a rack?
THANK YOU VERYYYYYYYYYYYYYYYYYYYYYYYY MUCH I was stuck here
Thank you!!! Make more of this kind of video. What about cam drawing in freecad!

Wanted to create an small chamfer around the sharp edges (tooth flanks) .
Doesn't work with chamfer tool and I don't know why.
Can you help me?
Thank u so much
I’ve been trying to make gears manually for over a month now but I guess that was all wasted time 😂
Exactly... where the f was that button?!...
Well explained, thank's.
💯
Wish I watched this video before. I was constructing gears from scratch in tinkercad. They work fine but the teeth are not as great as on these ones.
Do you know if it is possible to design a worm gear in Part Design>
How so you lay out key ways?
Thank you for video.
Thanks for this video!
Great
Nice boy
this was very usefull, thanks (;
Thanks♥️♥️♥️♥️
Is there no way to change the teeth size?
If you want to change the teeth size change the module number. To change teeth shape change the pressure angle. Hope this helps : )
Is this how you make a gear on a gear?
Yeah all you need to do is move one of the gears up on the z axis and then join them together
In those early version, one must draw each teeth in the sketch to made a gear.
seems to me the number of teeth is dependent. We must get paper and pencil and multiply by pi divide the pitch!!?? Im not that smart. Then it does not come out even!! ...oh i got it go backwards.
mfw when the gear is done in less than 20 mins
This is very lacking and not parametric.
If you need to change gear size later the gears will be missaligned :(
Thanks!
