Descrizione
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.

Very easy to use and gave me exactly what i needed
Great gear generator.
Can this also be used to generate the gear for the inside of a ring and not just the outside?
Yes and no. It's not directly supported but if you make a gear then pull the tooth tip and root out 0.25 module and subtract that modified gear from a cylinder it will make a valid internal gear. The good news is that I'm working on a version 2 of this add-in and it will directly support generating internal gears and provide a host of other awesome features. Send me an email and I'd be happy to send you an early, alpha, of v2. Just be aware that it is not ready for release, it is fully functional but there is a lot of work remaining to polish it and make it performant but it can be installed alongside v1.
Great add-in!
Thank-you, very nice and appreciated.
This plugin is perfect for creating herringbone gears
Thank you! Very comfortably!
Parameters are well documented and the resulting gears mesh nicely.
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.
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
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 for the addon
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!!
