The 19 pages that link to Gear train, each with the reason it gives.

• Mechanical clockRelated: It carries power from the clock’s source to its escapement and display.

• EscapementRelated: The escapement meters the gear train’s otherwise continuous drive from the power source.

• Water wheelRelated: Gearing adapts slow wheel rotation to machinery requiring different speeds.

• Least common multipleRelated: Tooth counts determine when marked teeth on multiple gears return to a shared alignment.

• WinchRelated: Gearing lets the winch trade drum speed for greater pulling force.

• WindmillRelated: Gearing adapts the rotor’s motion to the speed and force required by mill machinery.

• Astronomical clockRelated: Different gear ratios reproduce the unequal cycles of the Sun, Moon, and planets.

• AxleRelated: Gear axles support rotating gears and may carry torque through the train.

• Difference engineRelated: Interconnected gear trains store and transfer the engine’s numerical values.

• OdometerRelated: Mechanical odometers use gears to translate wheel rotation into numbered display movement.

• WatchmakingRelated: Its ratios carry motion from the power source toward the hands.

• Medieval technologyRelated: Gearing adapted wheel rotation to the speeds and forces needed by different machines.

• Ismail al-JazariRelated: Gears translate motion between components in several mechanisms documented by al-Jazari.
