Description

This tool allows you to create a 2D profile of an involute gear. This 2D profile is fully parametric, and can be padded with the PartDesign Pad feature.
For more detailed information see Wikipedia's entries for: Gear and Involute Gear

Usage

1. Go to the menu Part Design → Involute gear....
2. Set the Involute parameters.
3. Click OK
4. The involute gear is created outside of the active body. Drag and drop it into a body for the application of further features like padding.

Parameters

• Number of teeth: Sets the number of teeth.

• Modules: Pitch diameter divided by the number of teeth.

• Pressure angle: Acute angle between the line of action and a normal to the line connecting the gear centers. Default is 20 degrees. (More info)

• High precision: True or false

• External gear: True or false
