How does a flexible coupling transmit power?

A flexible coupling transmits power through a design that includes a flexible element, often referred to as a "spider." This flexible element allows for misalignment between the two shafts it connects, enabling them to maintain operational integrity even if they are not perfectly aligned. The spider absorbs shock loads and vibrations, contributing to smoother power transmission. This capability is crucial in applications where precision alignment is difficult to maintain or where there are variations in load.

The spider transmits torque and compensates for angular, parallel, and axial misalignments. This mechanism is essential in many industrial applications where machinery operates under varying loads and conditions. The flexibility offered by this design not only aids in managing misalignment but also helps to extend the life of the connected machinery by reducing wear and tear.
