Definitions

  • This invention relates to an arrangement in a roll assembly.
  • a conical centering sleeve is forced in between a roll ring and a roll shaft whereby the torsional moment is transmitted to the roll ring by this clamping-joint.
  • the advantage of this joint is that the roll ring and roll shaft can be manufactured with great margins and that the roll ring can easily be exchanged.
  • a troublesome drawback is that, when the conical sleeve is forced in between the roll ring and roll shaft, so great tensile stresses are introduced into the roll ring, which in most cases is made of cemented carbide, that it bursts.
  • a third type of joint the roll ring is prevented to rotate relatively the roll shaft by axial clamping, whereby the axial force is kept within fixed limits by applying a spring element in connection to the roll ring.
  • the drawbacks of this joint is that it requires narrow tolerances on roll ring and roll shaft which makes the production of roll ring and roll shaft expensive and which makes it difficult to mount the roll ring onto and to dismount it from the shaft.
  • the present invention relates to a joint that eliminates the drawbacks mentioned above and which allows large torsional moments to be transmitted, and wide tolerances to be used.
  • the production costs for the roll ring and roll shaft will be relatively low.
  • the joint allows a quick exchange of roll rings, since partly the roll ring is easy to dismount, partly easy to mount.
  • FIG. 1 shows in longitudinal section one embodiment of the invention
  • FIG. 2 shows another embodiment of the invention in longitudinal section.
  • FIG. 1 there are shown two roll rings 1,2 (three or more roll rings can of course be mounted on the roll shaft) mounted on a roll shaft 3, whereby the clearances are so great that both mounting and dismounting of the roll rings can be made quickly and simply by hand.
  • the roll joint must be provided with centering elements which are in the form of two pairs of wedge-type centering sleeves 4,5 or 7 bearing against each other and mounted between the roll ring and roll shaft. Thanks to the fact that two or several wedge-type centering sleeves are used the roll shaft or the inner surface of the roll ring does not have to be conical but can be straight. Bearing against one of the centering sleeves 5 or 7 4,6 of each pair is a resilient element 8, or 9 having a small spring force.
  • a distance ring 10 Radially outside the element 8 and bearing against the roll ring 1 there is positioned a distance ring 10. Another distance ring 11 is positioned between the two roll rings 1 and 2 and has one part bearing against the upper part of the resilient element 9. Another resilient element 12 having very great spring force is positioned axially outside the resilient element 8 and the distance ring 10. The resilient element 12 has an upper part bearing against the distance ring 10 and another part bearing against an upper part of the resilient element 8. Axially outside the resilient element 12 and bearing against the same there is positioned a press ring 13 which partially surrounds a mechanical lock nut 14 acting on the press ring 13. In order to effect the axial press force on the roll joint a suitable hydraulic press element is applied against the press ring.
  • FIG. 2 there is shown another embodiment of the roll joint.
  • a roll ring 22 is mounted on a roll shaft 21 whereby a centering element in the form of a conical sleeve 23 is mounted between the ring and shaft.
  • a centering element in the form of a conical sleeve 23 is mounted between the ring and shaft.
  • part of the shaft that is in contact with the sleeve 23 is tapered in order to provide a good contact surface for the conical sleeve 23.
  • a resilient element for instance a belleville washer 24 having very great spring force.
  • another resilient element for instance a cup spring 25 having a small spring force.
  • the resilient element 25 has not the same radial extension as the resilient element 24 and is positioned axially outside the same.
  • a press ring 26 which wholly or partially surrounds a mechanical lock nut 27.
  • a hydraulic nut or a similar device is used.
  • the centering sleeve (or sleeves) can be forced in between the shaft and the ring with a fixed force which is small in relation to the axial clamping force on the roll ring and, which is transmitted from the press ring by the first resilient element at the same time as the axial clamping force from the press ring is applied on the roll ring by the second resilient element, the spring force of which is many times greater than that of the first element.
  • the mounting is made in one operation, whereby axial clamping of the roll ring for transmission of the torsional moment is obtained at the same time as the roll ring is centered and gets support at its inner diameter by the centering sleeve without undesirable and injurous tensile stresses being introduced into the roll ring.
