  2. Epicyclic gearing - Wikipedia

    en.wikipedia.org/wiki/Epicyclic_gearing

    This planetary gear train consists of a sun gear (yellow), planet gears (blue) and carrier (green) inside a ring gear (red) 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").

  3. Transmission (mechanical device) - Wikipedia

    en.wikipedia.org/wiki/Transmission_(mechanical...

    A transmission (also called a gearbox) is a mechanical device which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. [1] [2] Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable ...

  4. Torque multiplier - Wikipedia

    en.wikipedia.org/wiki/Torque_multiplier

    A number of planet gears are arranged around and engaged with this sun gear, and therefore rotate. The outside casing of the multiplier is also engaged with the planet gear teeth, but is prevented from rotating by means of a reaction arm, causing the planet gears to orbit around the sun gear. The planet gears are held in a ‘planet carrier ...

  5. Reduction drive - Wikipedia

    en.wikipedia.org/wiki/Reduction_drive

    A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears. Reduction drives are used in engines of all kinds to increase the amount of torque per revolution of a shaft: the gearbox of any car is a ubiquitous example of a reduction drive. Common household uses are washing ...

    The Ravigneaux gearset is a double planetary gear set, invented by Pol Ravigneaux, who filed a patent application on July 28, 1949, in Neuilly-sur-Seine France. [1] This planetary gear set, commonly used in automatic transmissions, is constructed from two gear pairs, ring–planet and planetplanet. The gearset provides four forward gear ...

  8. Sun and planet gear - Wikipedia

    en.wikipedia.org/wiki/Sun_and_planet_gear

    Notice that the sun and flywheel rotate twice for every circuit of the planet when they have a 1:1 ratio of teeth. The sun and planet gear converted the vertical motion of a beam, driven by a steam engine, into circular motion using a 'planet', a cogwheel fixed at the end of the connecting rod (connected to the beam) of the engine. With the ...
