Involute Teeth Profile Spur Gear Design

The involute profile is most common used in Gear designed and is generated from base circle. There are many ways to create gear and many times we ignore the standard construction method to save time. This should be avoided. So I have created this model which is equation driven.

That means we only need 4 parameters to define the whole spur gear design.
1. Number of Teeths
2. Module
3. Pressure Angle (usually 20ยบ)
4. Face Width

Design Calculations for Spur Gear

For Calculations I have used SMath Studio. It is a free Mathematical Notebook MathCAD software. You can download it for free from their official website https://en.smath.com/view/SMathStudio/summary.

In this video tutorial we will learn to model equation driven Spur gear using base circle as basis of construction. I will explain how to model the gear.

Many parameters are used and driven by only Teeth, Pressure Angle and Module.

  1. Hi there, I have used formula from my Machine Design book. If you need, I can add a photo of that. :)
