| (54) | Rolling mill roll assembly |
| (57) A rolling mill roll assembly comprises a support shaft having a tapered section leading
from an abutment to an end section. A ring-shaped roll with inboard and outboard flanks
and a cylindrical bore is axially mounted on the shaft with its inboard flank seated
against the shaft abutment and with its cylindrical bore surrounding the tapered shaft
section. A tapered sleeve is inserted between the tapered section of the shaft and
the cylindrical bore of the roll, and a load ring is rotatably fixed with respect
to and axially shiftable on the end section of the shaft. A resilient spacer is interposed
between the load ring and the sleeve to yieldably maintain a gap between the load
ring and the outboard flank of the roll. A roll retainer mounted on the end section
of the shaft acts in an abutting relationship with the load ring and via the resilient
spacer to close the gap and axially wedge the tapered portion of the sleeve between
the tapered section of the shaft and the cylindrical bore of the roll. Bolt members
threaded in through bores in the roll retainer are torqued to urge the load ring against
the outboard flank of the roll, which in turn urges the outboard flank of the roll
against the shaft abutment. |
