Coupling systems are mechanisms that connect two or more components in a machine or structure, allowing them to work together effectively. They are commonly used in various applications, such as in automobiles, industrial machinery, and electrical systems, to transmit power or motion between parts. These systems can be classified into different types, including rigid couplings, flexible couplings, and magnetic couplings. Each type serves a specific purpose, such as accommodating misalignment, reducing vibration, or providing a non-contact connection. Proper selection of a coupling system is essential for optimal performance and longevity of the equipment.
