Helical Gear Generator

Helical Gear Generator

Hobbyist: Ross Korsky

Sistema operativo:


ATTENTION MAC USERS: If you experiance issues with the installer please e-mail me (ross.korsky@gmail.com) and I will provide a workaround. Autodesk makes the installers and they are aware of the issued. That said, the Mac installer has been broken for quite some time and I have little confidance that it will be fixed any time soon! 

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.

Informazioni sulla versione

Versione 1.0.3, 05/11/2018
1.0.3 All tooth profiles are now created on their own sketches. This is a workaround for a fusion bug where sketch profiles are not always properly recognized when sketched off of z=0. 1.0.2 Fixing various bugs broken by, or exposed by, recent changes to Fusion. * Textboxes no longer appear to support list formatting - this was causing ERROR messages to be suppressed. * Expanding the Gear Parameters group was causing an infinite preview loop leading to very poor performance and likely causing crashes. ** Having the Gear Parameters expanded and having preview enabled still carries a performance penalty of causing the preview to be generated multiple times instead of just once. ** It can take a few clicks to get the Gear Parameters group to expand ** all-in-all Fusion does not yet support the concept of providing messaging to the user in a way which does not trigger the preview to be regenerated Other changes: * Number of teeth can now be set from a user parameter (gear is not updated if the parameter is changed after gear generation) * Increased the number of decimal places to nine for 'length per revolution' in Gear Parameters

  • Exactly what I was looking for

    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!
    Erick Espinoza | maggio 01, 2019 Download verificato (Guida rapida)

    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.

  • It's not parametric
    Radek J | agosto 12, 2018 Download verificato (Guida rapida)

    It is not parametric :(

  • 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!!
