Abstract

A spool or reel for carrying spoolable or coilable material comprises first and second sides, a drum disposed there between at least one flange secured to a side and associated with the axis of rotation of the spool. The flange comprises a socket preferably centered about the axis of rotation and configured to receive a replaceable wear hub. The flange and replaceable wear hub are configured to transmit torque there between so that relative rotation between the components is minimized or eliminated.

Claims

1. A spool comprising:

a pair of sides;

a drum extending between the sides and centered substantially about an axis of spool rotation;

a flange associated with at least one side and comprising an outer face and a hub socket centered substantially about an axis of spool rotation and having a predetermined shape;

a replaceable hub configured to support rotation of the spool about the axis of rotation, configured to mate with the hub socket and configured so that when the hub resides in the hub socket an outer hub face and the flange outer face are substantially flush; and

an anti-rotation structure operable between the replaceable hub and the flange and configured to prevent rotation between the flange and the replaceable hub.

2. The spool of claim 1, wherein the anti-rotation structure structure is the shape of the hub socket.

3. The spool of claim 1, wherein the anti-rotation structure structure is one or more pins between the replaceable hub and drive flange.

4. The spool of claim 3, wherein the one or more pins are threaded fasteners securing the replaceable hub to the drive flange.

5. The spool of claim 2, wherein replaceable hub is secured to the drive flange with threaded fasteners.

6. The spool of claim 5, wherein the threaded fasteners react axial loading and little to no shear loading.

7. The spool of claim 1 wherein the replaceable hub is secured to the drive flange with an interference fit.

8. The spool of claim 7, wherein the predetermined shape is a circle.

9. The spool of claim 8, wherein the anti-rotation structure comprises one or more welds between the outer face of the hub and the drive flange.

10. The spool of claim 2, wherein the anti-rotation structure is splines.

11. The spool of claim 2 wherein the anti-rotation structure is a polygon.

12. The spool of claim 1 wherein the removable hub is removably secured to the drive flange with one or more welds.

13. The spool of claim 1, wherein the replaceable hub also comprises at least one drive component configured to operably engage a drive system for providing rotation to the spool.

14. The spool of claim 13, wherein the at least one drive component is a drive pin hole.

15. The spool of claim 1, wherein the flange further comprises one or more drive sockets displaced from the axis of rotation and a replaceable drive component configured to reside in the drive socket.

16. A method of rehabilitating the spool of claim 1 comprising:

removing any structure securing the replaceable hub to the flange;

withdrawing the replaceable wear hub from the socket; and

inserting a replacement hub into the socket.

17. A spool comprising:

a first side component comprising a central portion

a second side component comprising a central portion;

a drum disposed between the central portions of the first and second side components and centered substantially about an axis of spool rotation;

each central portion comprising an outer face and a hub socket centered substantially about the axis of spool rotation, the socket having a predetermined shape;

a replaceable hub associated with each central portion and configured to support rotation of the spool about the axis of rotation, each hub configured to mate with its associated hub socket and each hub configured so that when the hub resides in the hub socket an outer hub face and the central portion outer face are substantially flush;

a torque transfer structure operable between the replaceable hub and the central portion configured to transfer torque between the central portion and the replaceable hub; and

at least one securing device for each hub configured to removably secure the hub in the socket.

18. The spool of claim 17, wherein the torque transfer structure and the at least one securing devices are the same.

19. The spool of claim 17, wherein the torque transfer structure is the predetermined shape of the socket and hub.

20. The spool of claim 17, wherein at least one of the replaceable hubs also comprises at least one drive portion.

21. The spool of claim 17, wherein at least one of the central portions also comprises at least one replaceable drive portion.
