Abstract
A coupling assembly having an integral flange hub configured to bear against a flexible coupling element, and an external flange element configured to engage the hub to exert compressive force on the flexible coupling element. The assembly further includes a nut having inner threads configured to mate with a threaded extension of the hub to urge the hub and the external flange element into engagement with the flexible coupling element. The assembly may also include a tapered sleeve and a sleeve nut having inner threads configured to mate with the threaded extension of the tapered sleeve to secure the hub with a shaft.
Claims43
A coupling assembly comprising:
- a hub having a flange configured to bear against a flexible coupling element;
- an external flange element configured to engage the hub to exert compressive force on the flexible coupling element;
- and
- a nut having inner threads and configured to mate with a threaded extension of the hub to urge the hub and the external flange element into engagement with the flexible coupling element.
A system for securing two generally axially-aligned shafts, the system comprising:
- a flexible coupling element configured to be received by both a first hub assembly and a second hub assembly, to secure a first shaft with a second shaft;
- the first hub assembly comprising:
- a first hub having a flange and mountable on the first shaft, the flange of the first hub bearable against the flexible coupling element, the first hub having a threaded extension;
- a first outer flange configured to engage the first hub to exert compressive force on the flexible coupling element;
- and
- a first nut having inner threads and configured to mate with the threaded extension of the first hub to force the first hub flange and the first outer flange into engagement with the flexible coupling element;
- and
- the second hub assembly comprising:
- a second hub having a flange and mountable on the second shaft, the flange of the second hub bearable against the flexible coupling element, the second hub having a threaded extension;
- a second outer flange configured to engage the second hub to exert compressive force on the flexible coupling element;
- and
- a second nut having inner threads and configured to mate with the threaded extension of the second hub to force the second hub flange and the second outer flange into engagement with the flexible coupling element.
A method for installing a coupling hub assembly onto a shaft, comprising:
- placing a nut, an external flange element, and an inner flange hub onto a shaft;
- sliding the external flange element into engagement with the inner flange hub;
- installing a flexible coupling element in between the external flange element and the inner flange hub;
- and
- threading the nut having an inner threaded surface onto a threaded surface of the inner flange hub to tighten the nut against the external flange element to compress the flexible coupling element between the external flange element and the inner flange hub.
A method for disassembling a coupling hub assembly from a shaft, comprising:
- counterrotating a nut having inner threads to loosen the nut from a threaded surface of an inner flange hub to disengage the inner flange hub from an external flange element;
- removing a flexible coupling element from between the inner flange hub and the external flange element;
- and
- loosening or removing the nut, the external flange element, and the inner flange hub from the shaft.
A method for coupling two generally axially-aligned shafts, the method comprising:
- placing a first nut, a first outer flange, and a first hub having a flange onto a first shaft, and sliding the first outer flange into engagement with the first hub;
- placing a second nut, a second outer flange, and a second hub having a flange onto a second shaft, and sliding the second outer flange into engagement with the second hub;
- installing a flexible coupling element in between the first outer flange and the first hub flange, and in between the second outer flange and the second hub flange;
- threading the first nut having an inner threaded surface onto a threaded surface of the first hub to tighten the first nut against the first outer flange to compress the flexible coupling element between the first outer flange and the first hub;
- and
- threading the second nut having an inner threaded surface onto a threaded surface of the first hub to tighten the first nut against the first outer flange to compress the flexible coupling element between the first outer flange and the first hub.
A system for installing a coupling hub assembly onto a shaft, comprising:
- means for placing a nut, an external flange element, and an inner flange hub onto a shaft;
- means for sliding the external flange element into engagement with the inner flange hub;
- means for installing a flexible coupling element in between the external flange element and the inner flange hub;
- and
- means for threading the nut having an inner threaded surface onto a threaded surface of the inner flange hub to tighten the nut against the external flange element to compress the flexible coupling element between the external flange element and the inner flange hub.
A coupling assembly comprising:
- a hub having a flange configured to bear against a flexible coupling element, wherein the hub has a tapered inner surface configured to interface with an outer tapered surface of a sleeve, the sleeve mountable on a shaft and having a threaded extension;
