Project Overview
Designed a single-stage planetary gearbox assembly using Autodesk Inventor to demonstrate mechanical power transmission design, gear system kinematics, and parametric CAD modeling. The project focused on creating a functional gearbox layout capable of delivering high torque within a compact mechanical assembly.
Design Objectives
• Achieve a 5:1 gear reduction ratio
• Maintain compact gearbox geometry
• Ensure correct gear meshing and motion behavior
• Develop a fully constrained mechanical assembly
