Sprocket is a circular component with teeth or cogs that is used in machinery to transmit motion and force. It typically engages with a chain or belt, allowing for the transfer of energy between different parts of a machine. Sprockets are commonly found in bicycles, motorcycles, and various industrial machines. In addition to their mechanical applications, sprockets can also be used in robotics and automation systems. They come in various sizes and materials, depending on their intended use. Understanding how sprockets work is essential for anyone involved in engineering or mechanical design, including those working with gears and pulleys.
