 How to Design a Spur Gear in Fusion 360 – Step-by-Step Tutorial

Learn how to design a spur gear in Fusion 360 with this step-by-step guide! Perfect for beginners & pros

Master gear parameters, 3D modeling, and CAD design. Watch the video tutorial!

Introduction

Spur gears are one of the most common types of gears used in mechanical systems, from simple machines to advanced robotics. If you're looking to design a spur gear in Fusion 360, this step-by-step guide will walk you through the entire process, whether you're a beginner or an experienced CAD user.

By the end of this tutorial, you'll be able to:
✔ Understand spur gear parameters (module, teeth count, pressure angle)
✔ Sketch and model a gear in Fusion 360
✔ Create a 3D-printable or machinable gear
✔ Use parametric design for easy modifications

This guide is perfect for mechanical engineers, hobbyists, 3D printing enthusiasts, and CAD designers.

Step 1: Understanding Spur Gear Basics

Before jumping into Fusion 360, let’s cover the essential gear terminology:

  • Module (M): Determines gear size (pitch diameter = module × teeth count)

  • Number of Teeth (Z): Affects gear ratio and engagement

  • Pressure Angle (Commonly 20°): Influences gear strength and smoothness

  • Pitch Diameter: The diameter at which gears mesh properly

Knowing these will help you design accurate and functional gears.

Step 1: Setting Up Fusion 360

  1. Open Fusion 360 and create a new design.

  2. Select the "Design" workspace (if not already active).

Step 2: Sketching the Gear Profile

  1. Create a new sketch on the XY plane.

  2. Use the "Circle" tool to draw the pitch diameter (PD = Module × Teeth Count).

  3. Add the base circle (for involute gear teeth) using the formula:

    • Base Diameter (BD) = PD × cos(pressure angle)

  4. Use the "Involute Gear" add-in (or manually sketch teeth using equations).

💡 Pro Tip: Fusion 360 has a Spur Gear Generator in the "Tools > Add-ins" section—use it for faster results!

Step 3: Extruding the Gear

  1. Finish the sketch and select the gear profile.

  2. Use the "Extrude" tool (shortcut: E) to give the gear thickness.

  3. For realistic gears, add fillet edges to reduce stress concentrations.
