Introduction to Coupling
A coupling is a mechanical device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings are used in a wide range of applications, from small household appliances to large industrial machinery. They can compensate for misalignment between shafts, absorb shock and vibration, and provide overload protection. Different types of couplings include rigid couplings, flexible couplings, fluid couplings, and magnetic couplings, each designed to meet specific requirements in various industries. Coupling
