Helical Gear Generator

Helical Gear Generator

Hobbyist: Ross Korsky



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. 

Be sure to check out the Gear Down For What YouTube channel and on thingiverse - he is doing some amazing things with Helical Gears!



版本 1.0.3, 2018/11/5
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

    Thanks a lot

  • This is so good!

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

  • Very Helpful

    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.

    Installer worked for MacOS without a problem.

  • Just what I needed

    Simple to use. Works great.

  • Thanks!

    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 驗證下載 (這是什麼?)

    It is not parametric :(

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

    Very many thanks !


  • Works great

    Very easy to use and gave me exactly what i needed

  • Inside gear?
    Colin Bradburne | 四月 05, 2018 驗證下載 (這是什麼?)

    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 驗證下載 (這是什麼?)

    Great add-in!

  • Excellent for herringbone gears
    Nick Biederman | 十一月 27, 2017 驗證下載 (這是什麼?)

    This plugin is perfect for creating herringbone gears

  • Thanks!
    Igor Andreev | 七月 17, 2017 驗證下載 (這是什麼?)

    Thank you! Very comfortably!

  • Works Great!

    Parameters are well documented and the resulting gears mesh nicely.

  • Keeps crashing Fusion
    Bjørn Borud | 五月 27, 2017 驗證下載 (這是什麼?)

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

  • Excellent!
    Darrell Nevers | 五月 20, 2017 驗證下載 (這是什麼?)

    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 驗證下載 (這是什麼?)

    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.

    Easy to use and the results are fantastic!!
