A single command is added to the Model Create menu from which Spur Gears, Internal Gears and Rack Gears can be created.

Diametrical Pitch (in English units) or Module (in Metric units), as well as Pressure Angle, Number of Teeth, Root Fillet Radius and Gear Thickness (for extrusion), are common properties for all gear types.

Bore Hole Diameter can be specified for Spur gears; Outer Diameter for Internal gears and Height for Rack gears.

*NEW* The new version 1.1 adds a 'Clearance' property to provide additional backlash clearance.

Numerical values are displayed for pitch circles and heights and sketches for pitch alignment are also provided.

  • Thank you Scott!
    Davide Matera | May 30, 2021 Verified Download (What's this?)

    Easy and efficient, useful

  • Looks Good - Function Questionable
    Norman Doty | May 26, 2021 Verified Download (What's this?)

    I have yet to get an internal gear to mesh properly with any spur gear having matching parameters. The geometry generaterd for the internals appears to be wrong.  The teeth of the internals are well inside the Pitch Diameter circle.

  • Perfect for my project
    Adrian Lai | October 21, 2020 Verified Download (What's this?)

    Had to make a simple geartrain demo piece and this fits the bill exactly. Just have to figure out the gear meshing points manually but that's quite easy

  • Works really well
    Julian Gamboa | September 10, 2020 Verified Download (What's this?)

    The interface isn't the best, but if you know your parameters it works really well. It was easy to install and ran on the first try.

    Thanks for making this!

    Just installed this app and tried to launch fusion again but got a warning that 'acge226.dll' is missing and i have to do a fresh reinstall of fuision.  Proceed with caution.

    Trying to add new figure with default parameters, but do nothing. Spyr gears is worked normally. Uninstall twice, restart but not effect. Win7x64.

    Здравствуйте,хотел бы спросить, нашли ли вы решение.Просто столкнулся с такой же проблемой и информации в сети нету от слова совсем.

  • Simple and Easy
    Jocelyn Sicotte | May 18, 2020 Verified Download (What's this?)

    No complex parameters to get lost. Simple to understand and does a superb job!

  • need clearance for 3d print
    christopher bessin | May 12, 2020 Verified Download (What's this?)

    backlash/tolerance option?  Or anyone have a suggestion for how to tolerance in a slicer?

  • Nice
    Никита Брянцев | January 23, 2020 Verified Download (What's this?)

    Nice tool, really. But I got some strange problem creating gears with module less than 0.5. Any gear with module less than 0.5 appears to be sized exactly as 0.5 gear. Pitch diameter circle is correct, but it is inside the gear.

  • Overall
    XTY | January 13, 2020 Verified Download (What's this?)

    love it

  • Fantastic!
    Erik | October 02, 2019 Verified Download (What's this?)

    wonderful add-in. love it. stock add-in for spur gear does not have internal gear or racks. only thing this is missing I think is backlash?

  • Thank the good open source lord that this exists!!!
    John Smith | September 15, 2019 Verified Download (What's this?)

    just downloaded and installed it (on the latest fusion version) and it works!!! save me so much time!!!! oh my thank you thank you thank you!!!

  • I love it, so useful
    Sebastian Brendler | August 18, 2019 Verified Download (What's this?)

    But since the latest update of Fusion 360, I can't install it anymore...
    I think this has something to do with the new UI of Fusion 360.

    The only thing I hope you add is providing backlash! Will help to 3D print these

  • BEST!!
