Sun & Planetary Gear System

A sun and planetary gear system is a compact and efficient gear mechanism used in automobiles, robotics, and power transmission to provide high torque and speed reduction. In SolidWorks, it is designed using Extrude, Revolve, and Assembly features to model the sun gear, planet gears, ring gear, and carrier, with motion analysis to study torque distribution and efficiency. Typically made from hardened steel or alloy materials, it ensures smooth power transmission, load distribution, and space-saving design in various mechanical applications.
