    Formula If a simple gear ... The final gear ratio of the compound system is 1.62 × 2 ≈ 3.23. For every 3.23 revolutions of the smallest gear A, ...

  3. 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").

  4. Gear - Wikipedia

    en.wikipedia.org/wiki/Gear

    Worm-and-gear sets are a simple and compact way to achieve a high torque, low speed gear ratio. For example, helical gears are normally limited to gear ratios of less than 10:1 while worm-and-gear sets vary from 10:1 to 500:1. [45] A disadvantage is the potential for considerable sliding action, leading to low efficiency. [46]

    Total face width is the actual dimension of a gear blank including the portion that exceeds the effective face width, or as in double helical gears where the total face width includes any distance or gap separating right hand and left hand helices. For a cylindrical gear, effective face width is the portion that contacts the mating teeth.

  6. Ravigneaux planetary gearset - Wikipedia

    en.wikipedia.org/wiki/Ravigneaux_planetary_gearset

    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 planet–planet. The gearset provides four forward gear ...

  7. Simpson planetary gearset - Wikipedia

    en.wikipedia.org/wiki/Simpson_planetary_gearset

    The Simpson planetary gearset is a compound planetary gear train consisting of two planetary gearsets sharing a common sun gear. A Simpson gearset delivers three forward gears and one reverse, plus neutral, and is commonly employed in three and four ratio automatic transmissions . [ 1 ]

  8. Manual transmission - Wikipedia

    en.wikipedia.org/wiki/Manual_transmission

    The design of most manual transmissions for cars is that gear ratios are selected by locking selected gear pairs to the output shaft inside the transmission. This is a fundamental difference compared with a typical hydraulic automatic transmission, which uses an epicyclic (planetary) design, and a hydraulic torque converter.

    This advantageous geometric construction sets us free from Robert Willis' famous and tedious formula, [18] because all calculations are exclusively determined by lengths ratios, respectively teeth numbers on the abscissa for the 4 epicyclic ratios, and of rotational speeds on the 3rd ordinate for the 10 gear ratios.
