Amazing! Fully Parametric Fusion 360 Involute Gear

Let me know if you have seen anything like this before. I was unable to find a true parametric involute gear for Fusion, so I made one. It required a work-around for generating the involute curve, and a number of other modeling hacks to get it to not blow up when you change the number of teeth dramatically.

such a practical project idea. thanks

Sir, I'm highly interested in this, but do not understand most of what was said here. If it is possible to get a breakdown of these steps it would be much appreciated.

Is the model available for download? I could try to copy your work, but downloading it would save me the time.

would this work when designing sprockets?

[@mechanismguy5059]

I think sprockets might be easier. What makes spur gears hard is the mathematically defined involute profile curve. Doing a parametric sprocket is a good suggestion.

I would love to see how to implement two of these gears :D

I built that then had some trouble documenting a foolproof process. I'll try to get back to it and film another video. As I recall, the steps I took were:
1 Make a new empty file
2 Insert the gear as a new component, then unlink it
3 Insert the gear again, then unlink it (now there are two gears)
4 Make a sketched line representing the center distance
5 Join each gear to each end of the sketched line with a rotation joint
6 Make an equation to calculate the center distance = ((N1 + N2 +.5)/2)*Module
7 Do a move feature to rotate one gear to mesh properly with the other and not interfere
8 Add a gear joint between them
The result was a pair of gears which could be parametrically modified and always mesh properly. You just have to go and redefine the move command to tweak the rotation of one gear to make it look pretty every time you modify it.
