    Can Gearotic be used to design chain sprockets? If not, what does??

    Maybe, does this look right:

      I think on my Schwinn I'd unwind those teeth on a good hill, but that would make a hell of a nice shoulder badge tattoo. Nice fusion of Celtic and steam punk.

        Yes but limited at the moment.
        As a heads up Art as many know brought out Gearotic Motion [ GM ] with a view to it being an expandable gear designer.
        Like many projects it has grown but grown to the point where if he's have known he would have started differently.

        So basically Gearotic motion has reached the end of it's life.

        At present Art is writing Gearotic Thought [ GT ] which is still a work in progress and probably will stay like that.
        Format is identical to how Mach 3 ran, a release version and a development version for the brave

        There is now far more in GT than GM but not everything has been ported over, it's a question of priorities. Fortunately when you download you get both and the license is valid for both and in typical ART fashion valid for life.

        Sprockets are in both GM and GT



        Quick screen shot showing half the dropbox for types. One improvement on GT over GM is that it shows the profile of a tooth space as well [ top right ] which is good for grinding form tools or getting one wire eroded. this tooth profile is also saved with the sprocket / gear when you do a 2D DXF file.

        However to get back to Dennis's original enquiry and if you only want sprockets then there is a free sprocket designed called Sprocketeer 2 over at

          That's pretty neat... Sure has come a ways. I find myself being curious even though I have expensive software already.

            Demo program is free, just won't output anything until licensed.

              While still teaching I made a bunch of sprockets using the formulas in Machinery's Handbook.

              http://neme-s.org/SPROCKET.xls This links to the spreadsheet I made to do the calculations. In my 24th MH edition the info is on page 2350 in the Transmission Roller Chain section. My practice was to draw one tooth and then to circular copy to make the full drawing.

              I used Mastercam or Design Cad (an inexpensive and very capable CAD drawing program).

              If you need more info don't hesitate to ask. If anyone finds errors in the spreadsheet and points them out I will, of course, update the spreadsheet.

              http://neme-s.org/Clock_Pictures/4.htm Here is a photo of one of our clocks. Of course this clock was made in the years before administration went completely insane regarding guns in school in NAY form, even on a clock!
