Hammasratasverkosto, or gear train, is a mechanical system consisting of two or more meshing gears. The primary function of a gear train is to transmit rotational motion and torque from one shaft to another. The meshing teeth of the gears ensure that the rotation of one gear, known as the driver, causes the rotation of the other gear, called the driven. The relative sizes of the gears determine the speed and torque transfer. When a smaller gear drives a larger gear, the speed of the driven gear is reduced, while its torque is increased. Conversely, a larger gear driving a smaller gear results in an increased speed and reduced torque. This ability to change speed and torque makes gear trains essential components in a vast array of machinery.

Gear trains are widely utilized in applications such as automotive transmissions, where they allow for varying engine speeds to be matched to road speeds. They are also found in clocks and watches to precisely control the movement of hands, in industrial machinery for power transmission and speed reduction, and in simple hand tools like wrenches and drills. The specific arrangement of gears, including the number of gears and their sizes, dictates the overall gear ratio, which quantifies the change in speed and torque. Different types of gear trains exist, including simple, compound, and planetary gear trains, each offering unique advantages in terms of complexity, space-saving, and torque multiplication capabilities. The design and manufacturing of gear teeth are critical for efficient and smooth operation, minimizing wear and noise.
