Definitions

  • the rolls of these mutiple cold rolling step-back mills in constructions of the prior art are formed by annular roll elements which have external ring grooves and which are mounted precisely spaced spart from each other on a drive shaft. Spacer elements are provided which hold the roll elements apart; the roll elements are shrunk onto the shaft. The uniform development course of the rolling grooves is insured by a key-and-slot arrangement that passes through the entire group of roll elements and spacer elements.
  • FIG. 1a is a sectional view taken on the line 1a--1a of FIG. 1b, showing a construction in accordance with the prior art;
  • FIG. 1b is a fragmentary sectional view taken on the line 1b1b of FIG. 1a;
  • FIG. 10 is a fragmentary large scale sectional view, taken on the line 1c1c of FIG. 1b;
  • FIG. 2 is a sectional view, taken on the line 22 of FIG. 3, similar to FIG. la but showing an embodiment in accordance with the instant invention
  • FIG. 3 is a fragmentary sectional view, taken on the line 33 of FIG. 2;
  • FIG. 4 is a fragmentary large scale sectional view, similar to FIG. 3 but showing only a detail thereof.
  • FIGS. 1a1c there is shown a system in accordance with a construction of the prior art.
  • the key-and-slot arrangement extends throughout the entire group of roll and spacer elements.
  • the previously mentioned cracks, that develop in the roll elements, are shown in FIG. 10.
  • FIGS. 2-4 there are provided a series of, for instance three, roll elements 1 which are spaced apart from each other for precise predetermined distances, and which are heat shrunk onto a driving carrier shaft '7.
  • a plurality of spacer elements or spacer disks 2 are mounted on the shaft 7; the spacer disks 2 are mounted loosely on the shaft 7, though they are keyed to the shaft 7 each by means of a key 3 for positive driven connection therewith.
  • Each pair of adjacent roll elements 1 is separated by a spacer disk 2, so that along the axis of the shaft 7 roll elements 1 alternate with spacer disks 2.
  • Drive means are provided that establish a positive, though indirect, driving connection from the shaft 7, by way of the keys 3 and the spacer disks 2, to the roll elements 1.
  • These drive means comprise a radial recess 5 that is depressed in at least one of the flanks of each roll element 1 and that forms a chamber with a similar recess that is depressed in the flank of the adjoining spacer disk 2; and a drive member 6 is positioned in each of these chambers.
  • Each chamber has a cylindrical section, and the drive members 6 are cylindrical, and each fits into, and is disposed in, the cylindrical section of a chamber.
  • the radial recesses 5 are so positioned in the roll elements 1 in relation to the rolling groove that, upon the interleafing of corresponding roll elements 1 and spacer disks 2 and the insertion of the drive members 6, the roll elements 1 will be disposed along the shaft 7 in predetermined position relative to each other.
  • a driving carrier shaft a series of annular roll elements having external ring grooves and being heat shrunk onto said carrier shaft, a plurality of spacer disks loosely mounted and keyed on said shaft, each roll element being adjacent at least one spacer disk, and drive means establishing a driving connection between said carrier shaft and said roll elements, by way of said spacer disks comprising each roll element defining with at least one adjoining spacer disk a radial chamber, and a drive member fitting into and disposed in each chamber.
  • said chamber being formed of two opposite radial recesses of which one is defined in said spacer disk and the other in said roll element, said chamber including a cylindrical section, said drive member being cylindrical and fitting into and disposed in said section.
  • a driving carrier shaft In a multiple cold rolling mill of the step-back type, a driving carrier shaft, a series of annular roll elements having external ring grooves and being spaced apart from each other and mounted on said carrier shaft, a plurality of spacer elements loosely mounted on said shaft, at least some of the spacer elements being disposed each in a space between two roll elements so that on the carrier shaft roll and spacer elements alternate, said spacer elements being keyed to said carrier shaft, said roll elements being heat shrunk onto said carrier shaft, and drive means establishing .
  • a driving connection between said carrier shaft and said roll elements by way of said spacer elements comprising opposite radial recesses defined in each pair of adjoining elements forming a chamber therebetween, and a drive member fitting into and disposed in each chamber.
  • a driving shaft for use in a multiple cold rolling mill, a driving shaft, a series of annular roll elements having external ring grooves and being mounted on said shaft, a plurality of spacer disks mounted in positive driven connection on said shaft, each roll element being adjacent at least one spacer disk, and drive means establishing a driving connection from said shaft by way of at least some of said spacer disks to said roll elements comprising a radial chamber defined by each roll element with an adjoining spacer disk, and a drive member fitting into and disposed in each chamber, whereby torque Will be transmitted from said shaft to said spacer disks, and from at least some of said spacer disks to said drive members and thence to said roll elements.
