Introduction to Coupling
A coupling is a mechanical device that connects two shafts together at their ends for the purpose of transmitting power. Couplings are used in a wide range of applications, including industrial machinery, automotive, aerospace, and marine industries. They play a crucial role in ensuring the efficient and reliable operation of equipment by allowing for the transfer of torque while accommodating misalignment, vibration, and shock between the shafts. There are various types of couplings, such as rigid couplings, flexible couplings, fluid couplings, and magnetic couplings, each with its own unique features and advantages. Coupling
