What is a Flexible Diaphragm Coupling?
A Flexible Diaphragm Coupling is a mechanical device designed to connect two shafts while allowing for misalignment and vibration damping between them. This type of coupling is essential in various applications where flexibility, high torsional stiffness, and responsiveness to movement are critical.

How does a Flexible Diaphragm Coupling work?
The working principle of a Flexible Diaphragm Coupling involves a series of thin, flexible metal discs (diaphragms) that are mounted between two hubs. When the two shafts rotate, these diaphragms deform slightly, allowing the shafts to remain in alignment even when there is some degree of misalignment. This ensures efficient transfer of torque while minimizing wear and tear on the components.
