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 variety of applications, including industrial machinery, automotive, aerospace, and marine industries. They can compensate for misalignment between shafts, absorb shock and vibration, and protect the connected equipment from damage. There are different types of couplings, such as rigid couplings, flexible couplings, and fluid couplings, each with its own unique characteristics and applications.
