Gear External Workbench icon

Introduction edit

The Gear Workbench is an external workbench for manufacturing different types of gears and worm gears in FreeCAD. The parametric modelling allows the required geometries to be changed at any time. For example, by changing a few parameters, the involute gear becomes either a spur gear, helical gear or double helical gear.

In order for the results from Gear to be usable, a certain amount of basic knowledge about the different types of gearing is required. Module, pitch diameter or root diameter are common terms and should therefore be known.

In conjunction with 3D printing, home users now have the opportunity to design and produce gears and worm gears according to their own personal ideas and, if necessary, to adapt them to the constructional conditions.

Installation edit

The Gear Workbench can be installed via the   Addon Manager. For manual installation see Installing more workbenches.

After installation, the tools are available in the Gear toolbar and in the Gear menu.
