How to Design and Build a Wooden Planetary Gear Set

The hand-cranked wood model consists of two distinct planetary gear sets, each with its own unique configuration. The first Planetary Gear Set is driven by the sun gear and the ring gear is fixed in place. The Planet gears rotate around the sun gear.

The Second Planetary Gear Set is driven by the planet gear carrier with the Ring gear fixed in place. The planet gears rotate within the carrier.

The model is entirely constructed from wood, showcasing beautiful grain patterns and textures. The hand-cranked operation, allows viewers to appreciate the smooth motion and intricate interactions between gears. The model also includes three sets of wooden peg gears, precisely crafted to achieve the correct speed ratios for each planetary gear set.

Visual Appeal
As the hand crank is turned, viewers can observe:
• The mesmerizing rotation of multiple gears simultaneously
• The contrasting movements of the two planetary gear sets
• The intricate dance of the planet gears as they orbit within their respective systems

This wooden gear model is not only a functional demonstration of complex mechanical principles but also a stunning piece of kinetic art. It serves as an educational tool for understanding gear ratios and planetary gear systems while captivating audiences with its hypnotic motion and craftsmanship.
Whether you're a mechanical engineering enthusiast, a woodworking aficionado, or simply someone who appreciates intricate designs, this video of a hand-cranked wooden planetary gear model is sure to leave you in awe of the possibilities when art meets engineering.
