Definitions

  • Still another object of the invention is to decrease the give or yield in the mill and thereby to permit rolling to closer. tolerances.
  • a further object of the invention is to provide a mill wherein it is possible to use a smaller roll diameter with a consequent saving in the cost of the rolls. Smaller rolls also afiord lower roll pressure and less power requirement.

  • the necks 3 and 4 of which are carried in roller bearingsS. and .6, mounted in journal boxes 7 and 8 respectively.
  • each lower box 3 is bolted directly to the-bed, and the 7 corresponding upperbox 7 is-bolted to the boxfi by means of'a pair of strong bolts 9 engaging tapped holes 10 in the box i butnpassing freely through holes 11 in the box 7.'
  • the boxes are held together by nuts 12, so as to obviate the necessity for stands or the like.
  • Thedistance between the-rolls is adjusted approximately by spacers-33. .and shims 34 surrounding the bolts atent O 2 themselves.
  • the bearing 5 at each end of the roll 1 is mounted in a sleeve 13, the inner and outerv cylindrical surfaces of which are eccentric to each other.
  • the sleeve 13 can be turned in the boxes 7 and is retained in axial position by a split ring '14, which engages a groove 15 in the sleeve.
  • the sleeve is providedwith a projection 16.to which a socketed lever can be applied,,and by means of whichthe sleeve can be turned in the box.
  • the eccentricity of the sleeve is about .5 to 2 mm. and the position of the rollfcan, therefore, be adjusted about :35 to :1.5 mm. for a quarter turn of the sleeve 13. This is sutficient to, cover the intervals which may be conveniently obtainedby the use of shims together with the spacers. By these means it is possible to adjust the distance very accurately be tween the rolls 1 and 2.

  • the bearing 6 takes part in the axial movement and,
  • the roll 2 will be shifted in a direction depending upon thedirection in which the ring 21 is turned.
