Helical Gear Generator

Description

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 | March 31, 2021 Verified Download (What's this?)

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


  • Wrong dimension
    Olivier Lanneau | March 25, 2021 Verified Download (What's this?)

    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

    See the hover text / image on the Gear Standard field. Use the radial system (not normal system) for the behavior you are looking for (where module and tooth number result in a fixed gear diameter independent of helical angle). In the normal system changing the helical angle will change the gear diameter.


  • Excellent!
    Albert Questiaux | March 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.

    Ross Korsky (Publisher) | April 20, 2021

    Correction - screw gears, not worm gears. Cross helical mesh (aka screw gears) as can be made with this plugin have a point contact while worm gears have a line of contact and can carry significantly more load. I've dabbled with generating bevel gears but they are surprisingly not very standardized with multiple common tooth profiles in use for various reasons, mostly to do with manufacturing methods. My exploration into spherical involute profiles (which I did many years ago now) never got beyond the proof of concept stage, but I did manage to generate a few bevel gear profiles but IIRC fusion started to really chug on more than moderate tooth counts (I'm sure it would do better these days - they have made a lot of performance improvements over the years). As for spiral gears... the math gets nuts and it's frankly beyond me to work out for myself and I never found a source for generating the gear profiles programmatically - nor had the need myself to really force me to figure it out :P

    I want Win64


  • Outstanding
    Jorge Bula | October 09, 2020 Verified Download (What's this?)

    Thanks, excelent app


  • Lovely!
    Shane Galvin | August 18, 2020 Verified Download (What's this?)

    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 | June 29, 2020 Verified Download (What's this?)

    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 (Publisher) | July 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 | June 27, 2020 Verified Download (What's this?)

    I really like it, quick and easy to use 


  • fantastic
    Adrian Sippitt | May 22, 2020 Verified Download (What's this?)

    Brilliant, thanks so much


  • Exactly what I was looking for

    Thanks a lot


  • This is so good!
    Michael Hwang | March 21, 2020 Verified Download (What's this?)

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


  • THANK YOU
    Ivan Korotchenko | March 01, 2020 Verified Download (What's this?)

    THANK YOU


  • Very Helpful
    Eric Soderberg | January 03, 2020 Verified Download (What's this?)

    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

    Pablo Costas | April 15, 2019 Verified Download (What's this?)

    Installer worked for MacOS without a problem.

  • Thanks!
    Yuriy Skvortsov | February 08, 2019 Verified Download (What's this?)

    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 | August 12, 2018 Verified Download (What's this?)

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


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

    Very many thanks !

    Very easy to use and gave me exactly what i needed


  • Inside gear?
    Colin Bradburne | April 05, 2018 Verified Download (What's this?)

    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 | February 16, 2018 Verified Download (What's this?)

    Great add-in!


  • Excellent for herringbone gears
    Nick Biederman | November 27, 2017 Verified Download (What's this?)

    This plugin is perfect for creating herringbone gears


  • Thanks!
    Igor Andreev | July 17, 2017 Verified Download (What's this?)

    Thank you! Very comfortably!


  • Works Great!
    Michael Thiesen | June 05, 2017 Verified Download (What's this?)

    Parameters are well documented and the resulting gears mesh nicely.


  • Keeps crashing Fusion
    Bjørn Borud | May 27, 2017 Verified Download (What's this?)

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


  • Excellent!
    Darrell Nevers | May 20, 2017 Verified Download (What's this?)

    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 | February 03, 2017

    Thanks for the addon


  • Change active units
    Brian Stewart | January 18, 2017 Verified Download (What's this?)

    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 | December 06, 2016 Verified Download (What's this?)

    Easy to use and the results are fantastic!!
