Introduction to Couplings
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 industrial machinery and automotive engines to aerospace and marine systems. They play a crucial role in ensuring the efficient and reliable transfer of torque while accommodating various misalignments between the shafts, reducing vibration, and protecting the connected equipment from damage. There are different types of couplings, including rigid couplings, flexible couplings, and fluid couplings, each designed to meet specific requirements in different operating conditions.
