True Involute Spur Gear Generator

True Involute Spur Gear Generator

(OP)
We often use a gear driving a series of pins to move our equipment. I searched high and low for an affordable software package to help use generate involute profiles for this and stumbled across this fantastic gear generator and wanted to share:

http://woodgears.ca/gear/index.html

It has a fun demo to try, definitely worth a download if just to fiddle with it.

It's mostly 'geared' towards wood craftsmen who would print out and trace the gears but it will spit out a DXF which can be CNC cut. It does output the dxf as a series of short lines, so I like to clean it up in CAD by stitching them together with a spline.

I'm not advertising this, I just thought it might be useful for anyone looking for an inexpensive lower precision involute gear generator!

RE: True Involute Spur Gear Generator

I've had great success with http://www.camnetics.com/geartrax/index.htm in the past when I had to work on power transmissions.  It has the same segmented tooth profile as you mention above, but was accurate enough for use to CNC/laser them for prototypes.
