Good gear simulator?

Good gear simulator?
March 28, 2014 05:46AM
Hey,

Looking back over my last designs I see myself needing a good gear simulator. There are some paid versions like the one from woodgears.ca and gearsimulator v4 but they are either expensive or dont have stl export.

Any usable gear simulator you use?

Yes that goes for 120$ if you want stl export grinning smiley

Can it export dxf's that are usable with OpenSCAD? If so, just export them, import into OpenSCAD, extrude, and export to stl.

after i saw that i downloaded it, i don't think it will save anything but a video unless you purchase it.

i would have thought that there would be a opensource tool like that buy now.

but software is not my strong suit.

Famous, wonderful, free involute gear generating tools in OpenSCAD that everyone should know about:

Parametric Involute Bevel and Spur Gears by Greg Frost
Public Domain Involute Parameterized Gears by Leemon Baird

(I guess they are not as famous as they should be. winking smiley )

Good info from MattMoses in post, Gear dimensions

(saved that link in my Knoledge Base/Gears folder)

This is one of my favorite programs for generating gears, there's an online version and also a Windows binary

... whoops - sorry I didn't see you already knew about this.

Thanks for the compliment, ddseeker! smiling smiley

Folks also might be interested in this tutorial on generating spur gear profiles: Guerrilla guide to CNC machining, mold making, and resin casting, Chapter 6. There is interesting information about undercutting.

Hi!

You could use the free web app at www.me-bac.com. It's possible to create standard and corrected spur gears and download the dxf profile of the gear to use with your CAD software.

There's also a plug-in for sketchup for creating gears.

Thanks, I never realized that there were so many factors. I can't even begin to comprehend yet. This will take some time to learn smiling smiley

No gear simulator, but FreeCAD has an involute gear profile generator.

Switch to the Part Design workbench then go to the Part Design menu --> Involute gear...

Then set your parameters and click OK.


This creates an "InvoluteGear" 2D profile in the Model tree that you can then pad (extrude) with the Part Design Pad tool.


You can then cut a hole through it by a few means (boolean cut with cylinder, or map a sketch of a circle and add a pocket feature). At any time you can go back to that InvoluteGear profile and change its parameters, the solid will then update.

Once your design is finished you can export it to STL.
