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. 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.

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.įinally, 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.īe sure to check out the Gear Down For What YouTube channel and on thingiverse - he is doing some amazing things with Helical Gears!ĪTTENTION MAC USERS: If you experience issues with the installer please see this article first. Then if you still have trouble installing the plugin e-mail me ( and I will provide a workaround.Ĭorrection - screw gears, not worm gears. 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. Handedness in helical gears refers to the direction the teeth lean when the gear is placed flat on a table.

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. 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. For panning move the mouse while pressing the left mouse button.Helical gears resemble spur gears with the teeth at an angle. Once the gears are rendered you can use the mouse scroll wheel or the slider underneath the window to zoom in and out. The tool also supports profile shift to reduce the amount of undercut in gears with low tooth counts. n1 The tooth count n1 of gear one defines various configurations: Specify desired values in the parameters box and then click on the 'Update' button. The implementation is inspired by the subtractive process that Michal Zalewski's describes in part six of his excellent Guerrilla guide to CNC machining, mold making, and resin casting. The generated SVG drawing can be downloaded and imported in CAD applications or opened in the open source SVG editor Inkscape to export as dxf or other formats. The page runs in modern browsers with SVG support (if in doubt, use Chrome).
