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.
Claims19
A flexible coupling, comprising:
- a flexible diaphragm body having a first end and a second end;
- a member fixed to the first end of the flexible diaphragm body;
- and
- a splined member fixed to the second end of the flexible diaphragm body, wherein the splined member is configured to axially shift relative to a first rotatable member rotatably fixed to the splined member in response to axial displacement of the first rotatable member relative to a second rotatable member interconnected to the first rotatable member by the flexible coupling while transmitting torque between the first rotatable member and the second rotatable member.
A method of transmitting torque through a flexible coupling, comprising:
- applying an axial force component to a flexible coupling by changing axial offset between rotatable members interconnected by the flexible coupling;
- and
- reducing one or more of the axial force component and cyclic equivalent stress born by a diaphragm disk body of the flexible coupling by axially shifting an end of the flexible coupling relative to one of the interconnected rotatable members.
