A flexible coupling is a mechanical device used to connect two shafts while allowing for some degree of misalignment between them. This flexibility helps to reduce stress on the shafts and other components, which can prolong their lifespan. Flexible couplings are commonly used in various applications, including motors, pumps, and other machinery. These couplings can accommodate angular, parallel, and axial misalignments, making them versatile in different settings. They come in various designs, such as rubber, gear, and disc couplings, each suited for specific operational needs. By absorbing vibrations and shocks, flexible couplings enhance the overall performance of mechanical systems.
