What They Do

In turbomachinery applications, flexible diaphragm couplings are used to transmit torque from one shaft to another. The design consists of at least one metallic membrane that is attached to the outside diameter of a drive flange and transfers torque through the diaphragm to the inside diameter attachment point. Couplings are used to accommodate the potential misalignment between joining shafts.
