Introduction to Coupling
A coupling is a mechanical device used to connect two shafts together at their ends for the purpose of transmitting power. It allows for some degree of misalignment between the shafts, absorbs shock and vibration, and can protect the connected machinery from damage. Couplings are widely used in various industries, including automotive, aerospace, manufacturing, and power generation, ensuring the efficient and reliable operation of mechanical systems. Coupling
