Helical Gear Generator

Helical Gear Generator

Hobbyist: Ross Korsky

Sistema operativo:


ATTENTION MAC USERS: If you experience issues with the installer please see this article first. Then if you still have trouble installing the plugin e-mail me (ross.korsky@gmail.com) and I will provide a workaround.

Helical gears resemble spur gears with the teeth at an angle. They can be meshed in parallel or crossed orientations at 90 degrees or arbitrary angles and can be generated with as little as a single tooth forming a screw gear. 

Gears may be specified in either the 'Normal' or the 'Radial' system or the fixed profile Sunderland standard, any of which can be generated as either Left or Right handed. Handedness in helical gears refers to the direction the teeth lean when the gear is placed flat on a table. 

Using this add-in, proper Herringbone gears (such as the gears used for this add-in's thumbnail) can be created by using a Sunderland profile then mirroring the gear about one of its faces. In the case of Herringbone or other double-helix gears the handedness of the base gear is not as significant as it is for single helix gears - to effectively change the handedness of a Herringbone / double helix gear all you need to do is flip it over - whereas for a single helix gear it must be mirrored to change its handedness. 

Finally, by setting a helix angle of 0 degrees, Spur gears can be created and defined in the metric system (as opposed to the sample Spur Gear script which defines gears in the American system) with this add-in.

  • Great tool
    Zach Wyatt | marzo 31, 2021 Download verificato (Guida rapida)

    Very consistent and does the job very well. Much faster and more consistent than by hand. Great job!

  • Wrong dimension
    Olivier Lanneau | marzo 25, 2021 Download verificato (Guida rapida)

    Works great for spur gear, but dimension are wrong with an helix angle.

    Make a gear module 1mm with 31 teeth and draw on it a circle of 31mm diameter. The primitif diameter of the gear is much bigger than the 31mm circle.

    my parameters : Normal system, right, 30deg, 20deg, 1mm, 31, 0mm, 10mm

    Hope you could fix it, thanks

  • Excellent!
    Albert Questiaux | marzo 13, 2021

    Easy to use and also great for worm gears too. Just what I needed thanks. Just cant edit the gear once created in fusion.

    Now what about bevel and spiral bevel gears ... your next challenge.

    I want Win64

  • Outstanding
    Jorge Bula | ottobre 09, 2020 Download verificato (Guida rapida)

    Thanks, excelent app

  • Lovely!
    Shane Galvin | agosto 18, 2020 Download verificato (Guida rapida)

    Works for what I need. Wish it were parametric but oh well.

    And another thing: the bodies created are named "Healical Gear"... just a quick fix to line 877. ;)

  • herringbone gear is wrong
    Muhammet Ali Bulat | giugno 29, 2020 Download verificato (Guida rapida)

    I created two herringbone gear in surrender mode. first 18 tooth and second 72 tooth. they are not compatible. neither in the program nor in the 3D output.

    Ross Korsky (Autore) | luglio 02, 2020

    Did you remember to make one left handed and the other right handed? Helical gears must be of opposite hands to mesh in classical gearing applications.

  • Great generator
    Alex Axenti | giugno 27, 2020 Download verificato (Guida rapida)

    I really like it, quick and easy to use 

  • fantastic
    Adrian Sippitt | maggio 22, 2020 Download verificato (Guida rapida)

    Brilliant, thanks so much

  • Exactly what I was looking for
    Mustafa Naser | marzo 25, 2020 Download verificato (Guida rapida)

    Thanks a lot

  • This is so good!
    Michael Hwang | marzo 21, 2020 Download verificato (Guida rapida)

    This is really good, and can generate regular spur gears as well if you set the helix to 0 degrees.

  • Very Helpful
    Eric Soderberg | gennaio 03, 2020 Download verificato (Guida rapida)

    Great sucess using this generator to make function 3d printed gears.  A requested new feature would be the option to create a tapered helical gear.

  • Works good
    max ist | ottobre 03, 2019 Download verificato (Guida rapida)

    Easy to install, easy to use, perfect result - excelent! Thanks.

  • Thanks

    Thank you very much 

  • Nice!

    Works pretty good!

  • useful tool
    Pablo Costas | aprile 15, 2019 Download verificato (Guida rapida)

    Installer worked for MacOS without a problem.

  • Just what I needed
    Matt Whipple | aprile 06, 2019 Download verificato (Guida rapida)

    Simple to use. Works great.

  • Thanks!
    Yuriy Skvortsov | febbraio 08, 2019 Download verificato (Guida rapida)

    The installer still does not work for MacOS, but Ross was kind to provide a usable package by e-mail. The addon works great! Really easy to use and results are perfect.

  • Addendum with Radial sustem.
    Radek J | agosto 12, 2018 Download verificato (Guida rapida)

    Addendum and dadendum doesn't seem to do anything in Radial system. 

  • Thanks !!!
    Sergey Bob | luglio 22, 2018

    Very many thanks !


  • Works great
    Thomas Fort | maggio 20, 2018 Download verificato (Guida rapida)

    Very easy to use and gave me exactly what i needed

  • Inside gear?
    Colin Bradburne | aprile 05, 2018 Download verificato (Guida rapida)

    Great gear generator.

    Can this also be used to generate the gear for the inside of a ring and not just the outside?

  • Awesome
    Rusty Nielsen | febbraio 16, 2018 Download verificato (Guida rapida)

    Great add-in!

  • Excellent for herringbone gears
    Nick Biederman | novembre 27, 2017 Download verificato (Guida rapida)

    This plugin is perfect for creating herringbone gears

  • Thanks!
    Igor Andreev | luglio 17, 2017 Download verificato (Guida rapida)

    Thank you! Very comfortably!

  • Works Great!
    Michael Thiesen | giugno 05, 2017 Download verificato (Guida rapida)

    Parameters are well documented and the resulting gears mesh nicely.

  • Keeps crashing Fusion
    Bjørn Borud | maggio 27, 2017 Download verificato (Guida rapida)

    Haven't been able to use it since it consistently crashes Fusion 360.

  • Excellent!
    Darrell Nevers | maggio 20, 2017 Download verificato (Guida rapida)

    This definitely makes life quite a bit easier for designing gear boxes! Only downside is that the tooth count input won't accept parameters; it just throws an error – "Teeth – must be greater than 0." – when I try to use a pre-defined parameter

  • Thanks!!
    Sai Kishore | febbraio 03, 2017

    Thanks for the addon

  • Change active units
    Brian Stewart | gennaio 18, 2017 Download verificato (Guida rapida)

    Be nice to select either metric or inch for the units. Or have it use the default units for each design. Not everyone uses metric.

  • Exactly what I was looking for!
    Box Jockey | dicembre 06, 2016 Download verificato (Guida rapida)

    Easy to use and the results are fantastic!!
