BUILDUP ROLLING ROLL Russian patent published in 1999 - IPC

FIELD: rolling equipment, possibly manufacture of rolling rolls. SUBSTANCE: rolling roll includes arbor with bead having cone surface, bands and means for securing bands. Spacing sleeves are arranged in annular cavities of bands. Means for securing bands are in the form of fixing nut. Spacing sleeves are made of material with thermal expansion factor exceeding that of band material. Annular cavities of bands and adjoining contact surfaces of spacing sleeves and arbor bead are provided with cylindrical portions and cone portions with the same conicity. Diameters of cylindrical portions of band annular cavities are more than diameters of cylindrical portions of spacing sleeves and arbor bead. Difference between width of cone portions of annular cavities of bands and width of cone portions of spacing sleeves and arbor bead depends upon necessary rolling torque. EFFECT: possibility of providing necessary radial pressure values on contact surfaces of roll and maintaining their values even if roll operates in conditions of significant temperature drops. 3 cl, 3 dwg, 1 exp, 2 tbl
