Gear vs. Sprocket — What's the Difference?
Edited by Tayyaba Rehman — By Urooj Arif — Updated on April 16, 2024
A gear is a rotating machine part with teeth that mesh with another toothed part to transmit torque, whereas a sprocket is specifically designed to engage with a chain in machinery.

Key Differences
Gears are fundamental components in mechanical systems that transmit power and motion between shafts by meshing their teeth with those of another gear or component. In contrast, sprockets are designed to mesh with the links of a chain or a track, as seen in bicycles and motorcycles.
While gears can change the direction of force and modify the output speed and torque in a system, sprockets primarily transmit rotary motion to linear motion, or vice versa, without altering the direction.
Gears often operate within enclosed systems, like gearboxes, which protect them from external elements and allow for lubrication. On the other hand, sprockets typically work in more exposed settings where they interact directly with chains or tracks.
The design of gears includes a variety of types such as spur, helical, bevel, and worm gears, each suited to different engineering needs and applications. Conversely, sprockets generally have a simpler design, focused primarily on the number and spacing of teeth to fit specific chains or tracks.
Gears are part of a larger system of power transmission that includes various mechanical components, whereas sprockets are typically part of a simpler system focused on chain or track drives.
