Drawing gears in Sketchup.
Posted on January 22, 2011 by Richard

The following is a guide for designing gears in sketchup for 3D printing, CNC milling or similar. For a good introduction in general gear design see here. For an introduction to sketchup see the sketchup related links this page.

A collection of the gears seen in this page can be downloaded from the 3d warehouse.

To begin with, download the involute gear plugin and copy it to your sketchup plugin directory. This plug-in was not produced by me and all credit goes to Cadalog Inc for writing this very useful tool. Then open sketchup and choose ‘Involute Gear’ from the draw menu. From the dialogue box you are presented with three options.

A partir do Google Sketchup, e podem-se fazer toda uma data de rodas dentadas, direitas, a 45º, torcidas, dentes para dentro...

É bom!
