It's a shame the Fusion 360 gear tools are not what they could be as far as user friendly goes. Thank you for taking the time to explain how to make what they have work. You're videos don't put me to sleep either!
hah, I try my best to get to the point - it usually takes a bunch of takes to pare it down. :) I think the gear tools will catch up. In the meantime, I've also been using the gear tool from woodgears.ca - the software is well worth the low price tag, but it only works in Windows (although I'm about to try installing it in a windows virtualbox on MacOS where I'm sure it will work fine).
I hope so. I was rather surprised to learn that the gear tools in 360 were so basic. SketchUp has more gear options! I thought that being a "real" solid modeler it would have all sorts of options but nope, it's rather primitive. Fingers crossed for the next update though!
As long as I got your attention how would you go about making an elliptical gear that can mesh with a circular gear? I'm probably one of the few people who would want to know but it might make a good topic for a video.
Thank you thank you thank you... I'm jumping in to Fusion from MODO to draw some planet gears for water jet cutter (wood) and I knew nothing of gears and have spent 1 1/5 days learning Fusion and reading WIKI about involute gears and pressure angles and backlash etc. this is a life saver...
Great tips. I clicked the video hoping to see how to use motion link with gears, but the workflow you suggest by sketching the gear contacts is far more important and helpful!
Just a bit of info on reading the McMaster-Carr catalog, if you look at 1.32 in the video it shows the pitch of the gears is 32. Both of your equation use this number, 16/0.5 and 24/0.75, so you could have just entered 32/2.54 in both cases. 16/(0.5*2.54) is the same as 16/0.5/2.54 or 32/2.54. Nice video by the way, thanks for taking the time.
Haha of course - thanks for pointing this out. I'm actually just using the add-in for the project I'm working on right now and added the McMaster info to the video for completeness' sake. I should have looked over a bit and noticed that there's, of course, a pitch column provided in the catalog. Thanks for the comment.
A bit more info for anyone working in metric, if you need your gears using module here's how to use the Fusion script. Divide 25.4 by the module then divide by 2.54. So for a 0.8 module gear (25.4/0.8)/2.54 =12.5 for the Diametral pitch the script needs.
Rob, I am following your video and I get to the point where the driven gear is moved in the X-direction as specified. The tooth of the drive and driven gears don't line up correctly, there is an interference. I took a screen capture to show you, but I am not sure how to get it to you.
Thanks for this video - I know I'm a little late to the party, but I think it would be interesting to see torque relationships. I'm currently trying to create movement in a small space. I have a very weak brush-less motor (ie a cellphone vibration motor) and I challenged my self to gear it to move a 2 lbs object in a linear direction by pulling on a thread/string. Would you be interested in doing a video on such a thing?
Im working on a 3d model of welding a cylinder to a square plate but the cylinder has to lay flat on a 45 degree angle of the plate. how can i do this?
Very helpful video but the align command doesn't seem to be working for me. I select the center of a gear and then the center of the corresponding circle (as shown in the video) and the gear aligns it self correctly at first but when I press Ok or select another gear it just snaps to a seemingly random position and this happens every time with every gear I try. Any help on what I might be doing incorrect or what I could fix would be appreciated.
The align command dialog looks a little different now than it did when I made this video, but it looks like it still asks whether you want to align Components or Bodies. Are you choosing Bodies? I just tried to reproduce what I did in the video and it works if I'm aligning the gear Body but doesn't if I'm trying to align the gear Component (which contains the body).
Anupum Pant That's not a realistic solution because contact sets are very cpu intensive. Even the simplest contact sets can slow your computer to a crawl - gears meshing is more than you can ask of that feature. It's also not as predictable or smooth as you might expect. With or without contact sets, you still need to model the gears correctly - it's just the motion link that it would replace and that's the easy bit.
I'm only new to Fusion 360 myself, and I'm not really certain what he might have been trying to say, but I can guess. I do know that if you first created the gears as an appropriately constrained sketch based on parameters and extruded them from the sketch, then any changes to the sketch would be carried forward into the 3d gears. If you started with 3d gears, maybe you could project them onto a sketch plane, thus establishing a profile, then build them up properly from that profile. Basically rebuilding the wheel-pun intended... Anyone who know better than I, please advise.
Thanks I think I got your point..Creating a 3d model with the req. dia and teeth and projecting them and adding constraints to the projection sketch and extruding those sketch which would have in built constraints....Nice Idea..Thank you
I have followed your video... including motion link equation... the bevel gears i have from McMaster carr will not engage in rotation together.. I am at a loss what to do

Thanks, Rob.!This helped me figure out how to create some gears to repair a broken electric skateboard.

great explanation, It answers all my questions. Thank you for sharing your knowledge.

...or, since 25.4/2.54 = 10, just divide 10 by the required module. In your example case: 10/0.8 = 12.5
I haven't really looked into it yet but I need those formulas. Perfect. and even an example to go with them. Thanks.
Amazing video! Thanks!
Really great tutorial, well done sir!
Very helpful formulas. Thank you!
Hey! Have you done something with helical gears? i dont know how to do witchout gears genertor :/
Excellent tutorial! Thanks.
Thanks, I picked up the wood gears.ca program. It is very useful.
Rob,

Very informative, thanks

I have a very weak brush-less motor (ie a cellphone vibration motor) and I challenged my self to gear it to move a 2 lbs object in a linear direction by pulling on a thread/string. Would you be interested in doing a video on such a thing?
can you make some gear rack to use on the gears??
I need to make a ring gear with internal teeth and driven by a small pinion gear. Any advice on how to do this?
Thank you! This help a lot!

Yes, I selected "Bodies" and it didn't work. But I just now tried it with "Components" selected and it worked.
Which seems rather strange to me.
Same.
you just add a disclaimer in the beginning of these types of videos, something along the lines of , "DANGER MATH AHEAD"
Is it not easier to do Assemble > Enable all contact. Then you do not need to write a formula. they automatically mesh together

Ooh! True. I thought it was just my poor laptop running it slowly. It really is not very efficient.
A joint from component to sketch would update automatically,
Can you explain?

Wow!
Thanks :)
too quiet. You need more volume. Can't hear you without headphones full blast. Even then you're too quiet.

nice one..
