A coupling is a mechanical device that connects two shafts, enabling the tramission of power while accommodating misalignment and vibratio. It plays a crucial role in maintaining the efficiency and reliability of machinery by securely linking rotating components. Couplings come in various types such as flexible, rigid, fluid, and gear couplings, each suited for specific torque requirements and operational conditio. This veatility allows them to eure smooth operation and longevity across a wide range of industrial applicatio.
