Definitions

  • the invention relates generally to rolling mills, and is concerned in particular with an improved roll assembly of the so called "overhung" type, in which ring-shaped roll discs with cylindrical bores are centered on tapered shaft sections by means of tapered sleeves tightly wedged therebetween.
  • the tapered sleeve may not be fully wedged into its operative position prior to tightening of the retainer screws against the outboard roll flank. Thus, the roll will not be properly centered on the roll shaft. Secondly, the outboard roll flank can be damaged by the torque transmitting retainer screws.
  • the objective of the present invention is to provide an improved roll assembly which overcomes these drawbacks.
  • said load ring is splined to the end section of said shaft.
  • said resilient means comprises a disc spring interposed between an end of said sleeve and an adjacent surface of said load ring.
  • said roll retainer is threaded onto the end section of said shaft.
  • the roll assembly may comprise thrust buttons interposed between said bolt members and said load ring.
  • a roll assembly in accordance with the present invention includes a support shaft with a tapered section leading from an abutment to an end section, and a ring shaped roll with inboard and outboard flanks and a cylindrical bore.
  • the roll is axially mounted on the shaft with its inboard flank seated against the shaft abutment and with its cylindrical bore surrounding the tapered shaft sections.
  • a tapered sleeve is inserted between the tapered shaft section and the cylindrical roll bore.
  • a load ring is rotatably fixed with respect to and axially shiftable on the shaft end section on the outboard side of the roll.
  • a resilient element is interposed between the sleeve and the load ring to yieldably maintain an initial gap between the load ring and the outboard flank of the roll, and a roll retainer is mounted on the shaft end section outboard of the load ring.
  • the roll retainer acts in an abutting relationship with the load ring and via the resilient element to gradually and at least partially close the gap between the roll and load ring while gradually and precisely urging the sleeve into its wedged position. Screw members threaded through the roll retainer are then torqued to urge the load ring against the outboard flank of the roll, which in turn urges the inboard flank of the roll against the shaft abutment.
  • a roll assembly in accordance with the present invention is generally depicted at 10 .
  • the roll assembly comprises a support shaft 12 having a tapered section 14 leading from an abutment 16 provided by a pair of flingers 18a, 18b to an end section 20.
  • the shaft end section 20 is externally splined as at 22 and threaded as at 24.
  • a ring shaped roll 26 has inboard and outboard flanks 28, 30, external grooves 32, and a cylindrical bore 34.
  • the roll 26 is axially mounted on the shaft 12, with its inboard flank 28 seated against the abutment 16, and with its cylindrical bore 34 surrounding the tapered shaft section 14.
  • a tapered sleeve 36 is inserted between the tapered shaft section 14 and the cylindrical bore 34 of the roll 26.
  • the outboard end of the sleeve is internally splined as at 38 for mechanical interengagement with the external splines 22 of the shaft end section 20.
  • a load ring 40 is received on and is axially shiftable with respect to the shaft end section 20.
  • the load ring is rotatably fixed to the shaft by means of internal splines 42 coacting in mechanical interengagement with the external shaft splines 22.
  • a disc spring 44 is captured in an internal recess of the load ring by means of a spring retainer 46 held in place by a snap ring 48.
  • a roll retainer 50 is threaded onto the end section 20 of the roll shaft.
  • Jack bolts 52 are threaded in through bores containing thrust buttons 54.
  • the roll assembly is installed in stages as depicted by the following drawings:
  • the roll 26 is mounted on the shaft end section 20 with its inboard flank 28 in contact with the abutment 16, and with its cylindrical bore 34 surrounding the tapered shaft section 14.
  • the tapered sleeve 36 is inserted without a radial interference fit between the roll bore 34 and the shaft section 14.
  • the load ring 40 is mounted on the shaft end section 20, with its internal splines 44 interengaged with the external splines 22.
  • the disc spring 44 coacts via the spring retainer 46 with the outboard end of the sleeve 36 to yieldably maintain a gap 56 between the load ring and the outboard flank 30 of the roll.
  • the roll retainer 50 is threaded onto the shaft end section 20 and torqued to compress the disc spring 44 to an extent sufficient to partially close the gap 56, with the resulting resilient force being sufficient to create an interference fit between the tapered sleeve 36 and the roll bore 34 and tapered shaft section 14. At this juncture, therefore, the roll is precisely centered on the shaft.
  • the jack bolts 52 are torqued to urge the load ring 40 against the outboard flank 30 of the roll 26, which in turn results in the inboard roll flank 28 being urged against the abutment 16.
