Abstract

A cable reel of the present disclosure can include two flanges and a central drum being independently rotatable from one another. The drum, which can be configured to receive a cable, can be mounted on an axle. The two flanges can be rotationally mounted on the axle at opposing distal ends of the axle. Bearings in the flanges can allow for a full rotation of the flanges about the axle.

Claims

1. A cable reel comprising:

an axle comprising a first end and a second end;

a drum rotatably installed on the axle;

a first flange rotatably affixed proximate to the first end of the axle; and

a second flange rotatably affixed proximate to the second end of the axle;

wherein, when the drum, the first flange, and the second flange are installed on the axle, the drum, the first flange, and the second flange are independently rotatable with respect to one another and with respect to the axle during rotation of the first flange and the second flange.

2. The cable reel of claim 1, where the drum is rotatable at least 360 degrees about the axle.

3. The cable reel of claim 1, wherein the first flange is repositionable from a first position on the axle to a second position on the axle to increase a width between the first flange and the second flange.

4. The cable reel of claim 3, wherein the second flange is repositionable from a third position on the axle to a fourth position on the axle.

5. The cable reel of claim 1, further comprising a first barrier between the first flange and the drum and a second barrier between the second flange and the drum.

6. The cable reel of claim 5, wherein a coefficient of friction between a cable loaded on the drum and the first and second barriers is lower than the coefficient of friction between the cable loaded on the drum and the first and second flanges.

7. The cable reel of claim 5, wherein the first barrier or the second barrier comprises a lubricant.

8. The cable reel of claim 1, wherein the axle is rotatable at least 360 degrees.

9. A cable reel comprising:

an axle comprising a first end and a second end;

a drum comprising a first flange and a second flange, the drum affixed to the axle such that the drum and the axle rotate in unison;

a third flange rotatably affixed proximate the first end of the axle; and

a fourth flange rotatably affixed proximate the second end of the axle,

wherein the third flange and the fourth flange rotate independently of the axle and the drum, and wherein the third flange rotates independently of the fourth flange,

wherein a normalized average amount of force required to cause an unassisted rotation of the third flange and the fourth flange from a stationary position through an angle of 90°

is between 0.00013 and 0.00353, when the cable reel is loaded with a full amount of a cable and when a linear speed of the axle of the cable reel during the unassisted rotation is about 10.5 feet per minute, and wherein the normalized average amount of force required to cause the unassisted rotation of the third flange and the fourth flange from the stationary position through the angle of 90°

is calculated by dividing an average amount of force required to cause the unassisted rotation of the third flange and the fourth flange from the stationary position through the angle of 90°

by a weight of the cable reel loaded with the full amount of the cable.

10. The cable reel of claim 9, wherein the third flange is rotatably affixed proximate the first end of the axle by a first bearing comprising a mechanism for facilitating rotation of the third flange independent of the axle and the drum, and wherein the fourth flange is rotatably affixed proximate the second end of the axle by a second bearing comprising a mechanism for facilitating rotation of the fourth flange independent of the axle and the drum.

11. The cable reel of claim 9, wherein a normalized average amount of force required to cause an unassisted rotation of the third flange and the fourth flange from a stationary position through a payoff of about 240 inches of the cable from the cable reel is around 0.0059, when the cable reel is loaded with the full amount of the cable and when a linear speed of the axle of the cable reel during the unassisted rotation is about 10.5 feet per minute, and wherein the normalized average amount of force required to cause the unassisted rotation of the third flange and the fourth flange from the stationary position through the payoff of about 240 inches of the cable from the cable reel is calculated by dividing an average amount of force required to cause the unassisted rotation of the third flange and the fourth flange from the stationary position through the payoff of about 240 inches of the cable from the cable reel by the weight of the cable reel loaded with the full amount of the cable.

12. The cable reel of claim 9,

wherein the third flange is rotatably affixed proximate the first end of the axle by a first tapered bearing, and

wherein the fourth flange is rotatably affixed proximate the second end of the axle by a second tapered bearing.

13. The cable reel of claim 9, further comprising a wire guide assembly comprising a wire guide, the wire guide assembly attached to at least one of the third flange or the fourth flange.

14. The cable reel of claim 13, wherein the wire guide assembly further comprises a cross-bar and wherein the wire guide is slideably mounted to the cross-bar.

15. The cable reel of claim 9,

wherein the third flange comprises a first lip, the first lip protruding from the third flange and extending past a first edge of the first flange, the first lip creating a first space between the first lip and the first flange, and

wherein the fourth flange comprises a second lip, the second lip protruding from the fourth flange and extending past a second edge of the second flange, the second lip creating a second space between the second lip and the second flange.

16. The cable reel of claim 15, wherein each of the first space and the second space comprises a distance of one-quarter of an inch.

17. The cable reel of claim 15, wherein each of the first space and the second space comprises a size to prohibit binding of the first flange with the third flange and the second flange with the fourth flange.

18. The cable reel of claim 9, further comprising a scotch slideably attached to the axle.

19. A cable reel comprising:

an axle comprising a first end and a second end;

a drum comprising a first flange and a second flange, the drum affixed to the axle such that the drum and the axle rotate in unison;

a third flange rotatably affixed proximate the first end of the axle;

a fourth flange rotatably affixed proximate the second end of the axle,

wherein the third flange and the fourth flange rotate independently of the axle and the drum, and wherein the third flange rotates independently of the fourth flange,

wherein a normalized average amount of force required to cause an unassisted rotation of the third flange and the fourth flange from a stationary position through an angle of 90°

is about 0.007, when the cable reel is empty and when a linear speed of the axle of the cable reel during the unassisted rotation is about 10.5 feet per minute, and wherein the normalized average amount of force required to cause the unassisted rotation of the third flange and the fourth flange from the stationary position through the angle of 90°

is calculated by dividing an average amount of force required to cause the unassisted rotation of the third flange and the fourth flange from the stationary position through the angle of 90°

by a weight of the cable reel when the cable reel is empty,

wherein the third flange comprises a first lip, the first lip protruding from the third flange and extending past a first edge of the first flange, the first lip creating a first space between the first lip and the first flange, and

wherein the fourth flange comprises a second lip, the second lip protruding from the fourth flange and extending past a second edge of the second flange, the second lip creating a second space between the second lip and the second flange.
