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.

About This Version

Version 1.0.2, 7/7/2017
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!
    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.

    Could you please provide more information? For example are you using Mac or Window? Please try version 1.0.2 - I've put a band-aid on an infinite preview loop (introduced by a change in Fusion in the past couple of months) which occurred when the "gear parameters" section was expanded while the preview checkbox was checked.


  • 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


    Ross Korsky (Publisher) | July 06, 2017

    This has been addressed in version 1.0.2 - you should now be able to use parameters for the number of teeth. Gears will not be updated with changes to parameter values.


  • Thanks!!

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

    Easy to use and the results are fantastic!!
