what is gear train ?

A gear train is a mechanism that consists of two or more gears working together to transmit rotational motion and torque from one shaft to another. It is used to change the speed, direction, or amount of torque in a mechanical system.

Gears are toothed wheels that interlock with each other, and when they rotate, they transfer rotational motion. The gear that provides the initial input or receives the final output is called the driver gear, while the gear that is driven by the driver gear is called the driven gear.

The gear ratio of a gear train determines the relationship between the rotational speeds and torques of the driver and driven gears. The gear ratio is determined by the number of teeth on each gear. When a larger gear drives a smaller gear, the rotational speed decreases, but the torque increases. Conversely, when a smaller gear drives a larger gear, the rotational speed increases, but the torque decreases.

Gear trains are widely used in various mechanical devices and systems. They can be found in automobiles, bicycles, clocks, watches, and many other machines. They provide a way to transmit and control power efficiently and effectively in a wide range of applications.
