You need some way to apply torque on both the drive and driven gears for testing. One simple way is to print a drum that is attached to the gear and wrape a string around the drum and hang a milk jug filled with water. Torque is obviously the weight times the drum radius. Increase the weight until the gear fails. Eventually you figure out how to make a gear that is as stong as you need using minimum materials. It is actually fun to break stuff especially if it costs only 2 cents per gram. > > > > > -----Original Message----- > > From: Martin Dobbins [mailto:[email protected]] > > Sent: May-30-20 1:06 PM > > To: Enhanced Machine Controller (EMC) > > Subject: [Emc-users] Helical Gears > > > > The Fusion 360, Onshape, Alibre, Openscad, Freecad (surely not?) > discussion, challenge. > > > > Got me thinking so I searched: > > > > <https://hackaday.io/project/163953-crossed-helical-gears-in-openscad> > https://hackaday.io/project/163953-crossed-helical-gears-in-openscad > > > > <https://github.com/chrisspen/gears> > https://github.com/chrisspen/gears > > > > Libraries for a CAD program?
