Looks like it should be pretty straight forward as gears are a circular pattern of a feature pair (the tooth and the valley) but I missing something. Would someone point me to a layman's explanation of gear design or a freebie program that can at least provide the necessary parameters or preferably export a DXF profile?
Thanks
Take a look at Spur gears | ME-BAC
You can find a free web application to involute a spur gear and export the dxf profile.
Re: Simple spur gear design
It's hard to beat free but when you want more then the basic gear design free software offers, look into Gearotic Motion, seems it is $150usd now, it goes way beyond basic spur gears and once purchased any further updates or enhancements are no charge ever.
Art is continually expanding and updating the soft ware and is now barely recognizable from it's first generation, there is also a user forum where Art/Bob or others are quick to help.
They also have a demo version.
"Gearotic Motion Gear design Software"
Check out YouTube for Gearotic Motion as well for a lot of vids and demos
