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.
Claims24
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 comprising a hub socket centered substantially about the axis of spool rotation and having a non-circular 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.
3 more elements
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 non-circular 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 and 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.
5 more elements
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 circumferential shape other than a circle;
- a replaceable hub configured to support rotation of the spool about the axis of spool 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
- wherein rotation of the spool is transferred through the abutting surfaces of the hub and the flange.

- 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 comprising a hub socket centered substantially about the axis of spool rotation and having a non-circular predetermined shape;
- a replaceable hub configured to support rotation of the spool about the axis of rotation, configured to mate with the hub socket, configured so that when the hub resides in the hub socket an outer hub face and the flange outer face are substantially flush, and secured to the flange with one or more threaded fasteners;
- 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.
