Gear Design

Gears_2  These exercises will assist students to apply algebra, geometry and trigonometry to create a spur gear, tapered gear and a gear assembly.  There are three lessons that introduce the concept of a design that is controlled by geometry and equations, has students continually re-work a design, evolving it from a simple model to an advanced one, capable of producing a wide range of parts, allow students to solve certain design problems on their own.  To complete the lesson the students must use these skills that they have learned.  Many high-school students can do the math, but have never seen much use for it.  Several of the steps cannot be completed unless the student thinks in geometric terms.  The idea is to encourage the students to think.  Contributed by Dale Gibson.

    Thank you for this nice tut. Just needed this for school.

    next semester i most draw a spring…..maybe…


  • walsie


    Very nice tutorial, thanks to you’re site i learn everyday more and more off solidworks.

  • Richard Williams

    Excellently done. Lots of great tutorials that you have given to all of us. Very well done and I cannot wait until I get some other things done to use your method of making these gears. I wished I would have had this tutorial when I made my Pendulum Clock Gears. Great job and Thanks.

    Thank you for sharing this stuff. This stuff will be very useful in my next semester. Pls tell me more about this gear design because i want to make a project on this topics

    While the lessons on parametrics are good, The “gear design” is a bit misleading: I was hoping to find involute gear teeth, but only simple straight sided teeth are shown. In general – most gear teeth need to have an involute shape for reasonable efficiency and minimized wear. I will continue to search for involute examples elsewhere.

    Try Search Boston Gear for a more precise model.

    Hey,friend if you get perfact design of involute gear profile then please send me that link.ok.

  • Priyank Patel P.

    given link shows only images of that.But have you any design with calculations link?
