Abstract
A coupling for connecting a rotary power source to a driven device and accommodating misalignment between the source and device. The coupling has at least two identical modular center members having a plurality of alternative circumferential positions relative to each other and which also may be positioned with either axial end toward each other. The coupling includes hub members which may also be identical to the center members.

A flexible coupling connected between a rotary power source and a rotatable driven device along an axis between said power source and said driven device for accommodating misalignment between the power source and the driven device, the flexible coupling comprising:
- an input hub mounted on and connected to rotate with the power source and an output hum mounted on sand connected to rotate with said driven device;
- first and second identical center connectors connected together and positioned between said input and output hubs, each of said center connectors having a base and at least two circumferentially spaced-apart bosses integral with said base and projecting away from the other connector toward one of said hubs, a hole in each boss and at least two circumferentially spaced apart holes in each connector base;
- a first fastening member extending through a hole in a boss of one of the connectors and extending through one of the holes in the other connector and connecting said connectors,
- a second fastening member extending through a hole in a boss of the other of the connectors and extending through one of the holes in the one connector and connecting the connectors;
- a first flexible disc connected to said input hub and connected to said one of the connectors by said first fastening member extending through a hole in a boss of the one of the connectors and said one hole in the other connector;
- and
- a second flexible disc connected to said output hub and connected to said other of said connectors by said second fastening member extending through a hole in a boss of the other of the connectors and said one hole in the one connector;
- whereby rotary driving force provided by the rotary power source is transmitted through said input hub, through said flexible discs and connectors, and through said output hub to said driven device.
A flexible coupling, connected to a rotary power source and a device driven by the power source along an axis between the power source and driven device, for accommodating misalignment between the power source and the driven device, the flexible coupling comprising:
- identical input and output hubs respectively mounted on and connected to the power source and the driven device, each hum comprising an annular base and at least two spaced-apart bosses extending from said base toward the other hub;
- first and second connectors positioned between the two hubs for transmitting rotary force from one hub to the other, each connector being identical to the other and to each of the hubs, said first connector having its two spaced-apart bosses extending from its base toward the input hub and the second connector having its two spaced-apart bosses extending from its base toward the output hub;
- and
- fastening means connecting said first and second connectors, and
- a first flexible disc connected to the bosses of the first connector and also to the bosses of said input hub at a location spaced from the connection with the bosses of said first connector, and a second flexible disc connected to the bosses of the second connector and also to the bosses of said output hub at a location spaced from the connection with the bosses of the second connector whereby rotary driving force is transmitted through the hubs, the flexible disc and the connectors.
A flexible coupling, connected to a rotary power source and a device driven by the power source along an axis between the power source and the driven device, for accommodating misalignment between the power source and the driven device, the flexible coupling comprising:
- input and output hubs respectively mounted on and connected to the power source and the driven device, each hub comprising an annular base and at least two spaced-apart bosses extending from said base toward the other hub;
- first and second connectors positioned between the two hubs for transmitting rotary force from one hub to the other, each connector including an annular base and at least two spaced-apart bosses extending from said base, the two spaced-apart bosses of the first connector extending from the base of the first connector toward the input hub and the two spaced-apart bosses of the second connector extending from the base of the second connector toward the output hub;
- fastening means connecting said first and second connector;
- a first flexible disc connected to the bosses of the first connector and also connected to the bosses of said input hub at locations spaced from the connection with the bosses of said first connector, and a second flexible disc connected to the bosses of the second connector and also connected to the bosses of said output hub at a location spaced from the connections with the bosses of the second connector whereby rotary driving force is transmitted through the hubs, the flexible disc and the connectors,
- the fastening means including a fastening member extending through the first and second connectors and extending through one of the first flexible disc and the second flexible disc to fasten the first and second connectors and said one of the first flexible disc and the second flexible disc together.
