Helical Gear Generator

Helical Gear Generator

Hobbyist: Ross Korsky



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.

  • herringbone gear is wrong
    Muhammet Ali Bulat | 六月 29, 2020 验证的下载 (这是什么?)

    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.

    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

    I really like it, quick and easy to use 

  • fantastic

    Thanks a lot

  • This is so good!
    Michael Hwang | 三月 21, 2020 验证的下载 (这是什么?)

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

  • Very Helpful
    Eric Soderberg | 一月 03, 2020 验证的下载 (这是什么?)

    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 | 十月 03, 2019 验证的下载 (这是什么?)

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

  • Thanks

    Thank you very much 

  • Nice!
    Erick Espinoza | 五月 01, 2019 验证的下载 (这是什么?)

    Works pretty good!

  • useful tool
    Pablo Costas | 四月 15, 2019 验证的下载 (这是什么?)

    Installer worked for MacOS without a problem.

  • Just what I needed
    Matt Whipple | 四月 06, 2019 验证的下载 (这是什么?)

    Simple to use. Works great.

  • Thanks!
    Yuriy Skvortsov | 二月 08, 2019 验证的下载 (这是什么?)

    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.

  • It's not parametric
    Radek J | 八月 12, 2018 验证的下载 (这是什么?)

    It is not parametric :(

  • Thanks !!!
    Sergey Bob | 七月 22, 2018

    Very many thanks !


  • Works great
    Thomas Fort | 五月 20, 2018 验证的下载 (这是什么?)

    Very easy to use and gave me exactly what i needed

  • Inside gear?
    Colin Bradburne | 四月 05, 2018 验证的下载 (这是什么?)

    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 | 二月 16, 2018 验证的下载 (这是什么?)

    Great add-in!

  • Excellent for herringbone gears
    Nick Biederman | 十一月 27, 2017 验证的下载 (这是什么?)

    This plugin is perfect for creating herringbone gears

  • Thanks!
    Igor Andreev | 七月 17, 2017 验证的下载 (这是什么?)

    Thank you! Very comfortably!

  • Works Great!
    Michael Thiesen | 六月 05, 2017 验证的下载 (这是什么?)

    Parameters are well documented and the resulting gears mesh nicely.

  • Keeps crashing Fusion
    Bjørn Borud | 五月 27, 2017 验证的下载 (这是什么?)

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

  • Excellent!
    Darrell Nevers | 五月 20, 2017 验证的下载 (这是什么?)

    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 | 二月 03, 2017

    Thanks for the addon

  • Change active units
    Brian Stewart | 一月 18, 2017 验证的下载 (这是什么?)

    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 | 十二月 06, 2016 验证的下载 (这是什么?)

    Easy to use and the results are fantastic!!
