Rotatable cable reel
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.
1 . A system comprising:
an axle;
a drum comprising a first flange and a second flange, the drum rotatably installed on the axle;
a first rotational element comprising a first bearing, wherein the first bearing comprises at least one ball or at least one roller for facilitating rotation of the first rotational element; and
a second rotational element comprising a second bearing, wherein the second bearing comprises at least one ball or at least one roller for facilitating rotation of the second rotational element, and wherein the first rotational element rotates independent of the second rotational element.
2 . The system of claim 1 , wherein the first rotational element is rotatably mounted on the axle by the first bearing and the second rotational element is rotatably mounted on the axle by the second bearing.
3 . The system of claim 1 , wherein a normalized average amount of force required to cause an unassisted rotation of the first rotational element and the second rotational element from a stationary position through an angle of 90° is less than 0.00458, when the drum is loaded with a full amount of a cable and when a linear speed of the axle of the system 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 first rotational element and the second rotational element 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 first rotational element and the second rotational element from the stationary position through the angle of 90° by a weight of the drum loaded with the full amount of the cable.
4 . A system comprising:
an axle;
a drum comprising a first flange and a second flange, the drum rotatably installed on the axle;
a first rotational element; and
a second rotational element, wherein a normalized average amount of force required to cause an unassisted rotation of the first rotational element and the second rotational element from a stationary position through an angle of 90° is less than 0.00458, when the drum is loaded with a full amount of a cable and when a linear speed of the axle of the system 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 first rotational element and the second rotational element 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 first rotational element and the second rotational element from the stationary position through the angle of 90° by a weight of the drum loaded with the full amount of the cable.
5 . The system of claim 4 , wherein the first rotational element is rotatably mounted on the axle by a first bearing and the second rotational element is rotatably mounted on the axle by a second bearing.
6 . A system comprising:
an axle;
a drum comprising a first flange and a second flange, the drum affixed on the axle such that the drum and the axle rotate together;
a first rotational element comprising a first bearing, wherein the first bearing comprises at least one ball or at least one roller for facilitating rotation of the first rotational element; and
a second rotational element comprising a second bearing, wherein the second bearing comprises at least one ball or at least one roller for facilitating rotation of the second rotational element, and wherein the first rotational element rotates independent of the second rotational element.
7 . The system of claim 6 , wherein the first rotational element is rotatably mounted on the axle by the first bearing and the second rotational element is rotatably mounted on the axle by the second bearing.
8 . The system of claim 6 , wherein a normalized average amount of force required to cause an unassisted rotation of the first rotational element and the second rotational element from a stationary position through an angle of 90° is less than 0.00458, when the drum is loaded with a full amount of a cable and when a linear speed of the axle of the system 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 first rotational element and the second rotational element 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 first rotational element and the second rotational element from the stationary position through the angle of 90° by a weight of the drum loaded with the full amount of the cable.
9 . A system comprising:
an axle;
a drum comprising a first flange and a second flange, the drum affixed on the axle such that the drum and the axle rotate together;
a first rotational element; and
a second rotational element, wherein a normalized average amount of force required to cause an unassisted rotation of the first rotational element and the second rotational element from a stationary position through an angle of 90° is less than 0.00458, when the drum is loaded with a full amount of a cable and when a linear speed of the axle of the system 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 first rotational element and the second rotational element 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 first rotational element and the second rotational element from the stationary position through the angle of 90° by a weight of the drum loaded with the full amount of the cable.
