The clock uses an idler wheel to move the hour ring so it doesn’t need a separate hour hand. After he built his first design, [wyojustin] realized he could add a planetary gear that could move ...

The Harmonic Drive is a key part of countless robotic applications. Incredibly simple yet quite odd to watch, this gear system is extremely precise with an impressive torque-to-weight ratio, even if ...

A single planetary gear set consists of a central sun gear surrounded by a ring gear and smaller planet gears rotating between them on a planet gear carrier. Compound planetary gear sets multiply the ...

The motor is geared to the planetary ring gear. At launch, the sun is locked to the case so that power flows through the planetary carrier for an overall ratio of 17.0:1. Then around 30 mph ...

he still uses planetary terminology to explain how it works. The inner sun gear is a rotor with four pairs of bar magnets on its outer circumference. An outer ring gear has ten pairs of magnets ...

Planetary rings are among the most intriguing structures of our solar system and have fascinated generations of astronomers. Collating emerging knowledge in the field, this volume reviews our current ...

Each of the planet gears simultaneously applies a torque to the rotating planet member that then applies a torque to the output shaft (back side). Planetary cone reducers operate on a similar ...

Whether as a sponsor or donor, a member or volunteer, or an employee or fellow, you can make a difference. The ultimate goal of planetary protection for outbound missions is to prevent harmful ...

Planetary science is the study of the celestial bodies that orbit stars, with a particular focus on our own solar system. This includes studying the formation and evolution of planets, the moons ...
