Belt systems are mechanical devices used to transfer power and motion between different components in machinery. They consist of a looped strip, often made of rubber or fabric, that connects pulleys or gears. These systems are commonly found in various applications, including conveyor belts in factories and automobile engines. Belt systems can be classified into different types, such as flat belts, V-belts, and timing belts, each designed for specific functions. They are essential for efficient operation in many industries, providing a reliable means of moving materials or driving machinery while minimizing wear and tear on components.
