Abstract: A method of transmitting torque through a flexible coupling includes driving a first rotatable member with a second rotatable member, applying an axial force component to the a flexible coupling connecting the first rotatable member and the second rotatable member by changing an axial offset between the first rotatable member and the second rotatable member interconnected by the flexible coupling, reducing one or more of the axial force component and cyclic equivalent stress born by a flexible diaphragm body of the flexible coupling by axially shifting the first end of the flexible diaphragm body relative to one of the interconnected rotatable members, and affixing a splined member to a second end of the flexible coupling, wherein the flexible diaphragm body has an inner diameter that is greater than an inner diameter of the splined member.

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 a flexure, a first drive member defining an axis and connected to the flexure, and a second drive member. The second drive member defines an axis and is connected to the flexure on a side of the flexure opposite the first drive member. An angular stop is fixed within the first drive member, extends through a portion of the second drive member, and is arranged to limit angular misalignment of the first drive member axis relative to the second drive member axis while transmitting torque between the first and second drive members.

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.
