Sistema operativo:


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.

    fail mesage: The selected file does not exist.

    Håvard Houen | aprile 29, 2024

    Could the problem be that your machine is not running Win64? I got the same error message on my home computer with WIN32, but it works fine on my office computer ( Running Win64)

    how to change Pitch Diameter?

    Antoine ROMAND | agosto 03, 2023

    You can't change the pitch diameter : he is a function of the module and the number of teeth. So, change one of these 2 parameters will modify the pitch diameter. Hope it will help you.

  • Is FM Gears working?

    Hello! When I am creating a gear using FM Gears, the application shows the inscription "The selected file does not exist."

    What is the problem could be there?

    Thank you

  • Looks Good - Function Questionable
    Norman Doty | maggio 26, 2021 Download verificato (Guida rapida)

    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.

    Scott Ferguson (Autore) | giugno 01, 2021

    You should email the author with *complete* details about the input parameters used, the results achieved and the results that were expected.

  • Perfect for my project
    Adrian Lai | ottobre 21, 2020 Download verificato (Guida rapida)

    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 | settembre 10, 2020 Download verificato (Guida rapida)

    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!

  • need clearance for 3d print
    christopher bessin | maggio 12, 2020 Download verificato (Guida rapida)

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

  • Excellent
    Geoff Arnold | aprile 23, 2020 Download verificato (Guida rapida)

    I use this for making 3d printed gears and I have always found it easy to use and obtain excellent results.

    Norman Doty | maggio 26, 2021

    That is what I intend to use it for too (mainly). Have you done anything with internal gears? The geometry it generates for them seems to be off when you exceed somewhere between 100 and 150 teeth. I'm trying to create planetary gear trains so large numbers there are common.

  • Very useful
    Henry Casson | febbraio 07, 2020

    The module entry has a minimum of 0.5 mm,  and the default minimum is entered if you put in anything smaller, so those of us who are designing watch mechanisms , which may use involute gears for some functions, have to make the gear and then subsequently scale the result. This is not stated anywhere, so look out for it. 

    Rodolfo Bertoni | maggio 06, 2020

    True, I also had trouble creating a 0.289473 module gear. After finishing, I had to resize with the scale so that it was in the exact size.

  • Nice
    Nikita Bryantsev | gennaio 23, 2020 Download verificato (Guida rapida)

    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.

    I was flailing around trying to figure out how to make a gear, and then I found this. Problem solved, and solved easily.

  • Fantastic!
    Erik | ottobre 02, 2019 Download verificato (Guida rapida)

    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?

  • One of the most useful tool
    Francesco Mistretta | settembre 28, 2019 Download verificato (Guida rapida)

    There's not much to say, it allows you to create perfect gears in seconds. It's so useful and well made that it should come standard with all products!

    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.

    Evgeny Ivakhnik | marzo 14, 2019 Download verificato (Guida rapida)

    how can i adjust a tolerance of calculations?

    Scott Ferguson (Autore) | marzo 15, 2019

    We're very sorry for the inconvenience, we just solved the problem of inserting images when the drawing was georeferenced by Civil3D in the latest CAD-Earth update v5.1.21. The problem was sometimes AutoCAD saved the point location coordinates as latitude/longitude instead of UTM XY coordinates. We've modified the source code to detect when the coordinates in latitude/longitude and do the conversion to XY. We are continuously improving CAD-Earth and fixing bugs reported by our users. If you wish we can give you a free CAD-Earth Plus1-year license for all the inconveniences caused. (Your requested refund was entirely processed last month)
