  • Epicyclic gearing - Wikipedia
    An epicyclic gear train (also known as a planetary gearset) is a gear reduction assembly consisting of two gears mounted so that the center of one gear (the "planet") revolves around the center of the other (the "sun") A carrier connects the centers of the two gears and rotates, to carry the planet gear (s) around the sun gear
  • Planetary Gear: Design, Parts, Function, Ratio Uses [PDF]
    Planetary gears are at the heart of modern engineering and are used in basic plant machinery to electric vehicles These are also known as epicyclic gears, consist of two gears so that the center of one gear rotates around the center of the other
  • Planetary Gear: Explained - Engineering Cheat Sheet
    Planetary gear trains (PGTs), known for their compact structure, wide transmission range, and high efficiency, are typically the core structure of AT mechanisms A planetary gearset allows automatic transmissions to seamlessly adjust to different speeds This results in a more comfortable and effortless driving experience
  • How does a planetary gear work? - tec-science
    In contrast to stationary gears, planetary gears (also called epicyclic gears) are characterized by moving axis of rotation! At this point, the necessity of a symmetrical arrangement of the planet gears becomes also apparent, as otherwise enormous unbalance forces would occur at high rotational speeds
