Abstract: A flexible coupling includes a flexible diaphragm body having a first end and a second end. A member is fixed to the first end of the flexible diaphragm body. A splined member is fixed to the second end of the flexible diaphragm body. The splined member is configured to shift relative to a rotatable member rotatably fixed thereto in response to axial displacement of rotatable members interconnected by the flexible coupling. The ratio of inner diameter to the outer diameter is selected to allow for packaging the flexible coupling in a confined space.

Abstract: A flexible coupling includes an input body, an output body offset from the input body, and a flexible lattice body. The flexible lattice body includes a flex beam member coupling the input body to the output body. The flex beam member has a rounded cross-sectional area with a centrally disposed minimum cross-sectional area to reduce peak stress in the flex beam member while transferring torque and accommodating misalignment between the input body and the output body. The flexible coupling is jointless, simplifying fabrication, and has a free-form geometry, reducing weight.
