Definitions

  • Each of the segments are provided at their longi- I .t tudinal edges with supporting projections and recesses I I arranged therebetween to receive the supporting pro- [56] References Cited jections of adjacent segments.
  • the segments may be UNITED STATES PATENTS fixed to the roller coreby means of bolts, screws or 538,475 4/1895 Albrecht 425/107 cooled shrunk rings overlapping projections on each of 1,357,141 10 1920 Bibb v the segments 2,958,903 11/1960 Decker 425/ 5/1953 Rimmel 29/124 X 12 Claims, 3 Drawing Figures 1 ROLLER-TYPE PRESS
  • the invention relates to a roller type press, the rollers of which have a'roller core on which latter a plurality of segments is secured to form a complete annulus.
  • the end faces with which the segments lie opposite each other mainly extend radially or at an angle relative to the radius and that in a manner as to form a'gap enlarging in the direction of the roller core.
  • lt is an object of the present invention to reduce the maximum surface pressure with the given pressing force and .to avoid the occurrence of the abovementioned tilting moments.
  • this problem is solved in that the segments are provided at their longitudinal edges with a plurality of supporting projections and recesses arranged between each of said supporting projections to receive the supporting projections of the adjacent segments.
  • the said supporting projections and the recesses extend from the bearing surface of the segments over a limited length of the height of the segments.
  • a particularly useful embodiment is characterized in that the upper sides of the supporting roots and of the recesses are arranged at an acute angle relative to the roller radius.
  • the supporting projections should project so far that the supporting width over the ends of the supporting projections is at least equal to the length of arc of the segments on the periphery of the roller core.
  • the contact surface between the roller core and the segments may be cylindrical.
  • the fixing of the segments may be made in such a manner that they are secured with their ends to the roller core by means of bolts or screws.
  • the segments may also be provided at their ends with projections, the fixing means being two cooled shrunk rings over-lapping the projections.
  • FIG. 1 is a plan view of-asection of a roller with segments according to theinvention
  • FIG. 2 is a cross-section along the line llll in FIG.
  • F IG. 3 is a view of a segment according to the invention from below.
  • the roller shown in thedrawing may be the roller of a roller-type press operating on two contra-rotating rollers for the compactingof'bulk material, for example the roller of a roller-'typ'e briquette press or rather the of shells.
  • the embodiment shows three supporting projections 14 of equal width and symmetrically arranged along one of the longitudinal edges of the segment 6, and two recesses 16 arranged between said supporting projections 14.
  • two supporting projections 18 again in symmetrical arrangement, and two additional external supporting projections 20 having half the width of the supporting projections 18.
  • recesses 22 are provided in the opposite longitudinal edge said segment 6.
  • Recesses 24 are provided between each of the supporting roots 18 and 20. The projections and the recesses are so defined in their dimensions as to allow the projections to have sufficient play in their engagement into the recesses.
  • the total bearing surface of the segments 6 is substantially equal to the bearing surface in known segments having plane end faces. But by the arrangement of the projections according to the invention, the supporting width b is increased over the supporting width 0 in the known segments. According to this the end pressure is substantially reduced and occurrence of tilting moments avoided since now the line of action of the resultant always extends within the bearing surface of the segment.
  • the segments according to the invention are made by chill casting, the manufacture of the projections and recesses presenting no difficulties.
  • the fixing of the segments on the roller core may be made in usual manner. So, for example the segments may be secured at their ends to the roller core by means of bolts or screws '15. Otherwise, the segments may be provided at their ends, as shown in the drawing, with projections 24', the fixing means being in that case two shrunk rings 17 overlapping the projections; suitably the shrunk rings are cooled in case of roller presses for the pressing process of hot material.
  • the segments according to the invention are particularly useful in rollers having a roller core with a cylindrical surface.
  • the periphery 26 of the segments may either be smooth or may be provided with moulds, as the case may be.
  • a roller-type press comprising at least one roller having a roller core, a plurality of segments secured to said core thereby forming a complete annulus, said segments being provided along the longitudinal edges thereof with a plurality of supporting projections and recesses arranged between each of said supporting projections to receive the supporting projections of an adjacent segment.
  • a roller type press as claimed in claim 2 wherein at least a portion of the sides of said supporting projections and said recesses form an acute angle with a radius vector of said roller core.
  • each of said segments are provided at their ends with projections extending in the axial direction of the hollow core, said segments being secured by a pair of cooled shrunk rings overlapping said projections.
  • a roller-type press as claimed in claim 1 wherein at least a portion of the sides of said supporting projections and said recesses form an acute angle with a radius vector of said roller core 9.
  • a roller-type press as claimed in claim 1 wherein said segments are disposed along an arc of said roller core and said supporting projections provide a supporting width at least equal to the length of said are of said roller core.
  • each of said segments are provided at their ends with projections extending in the axial direction of the hollow core, said segments being secured by a pair of cooled shrunk rings overlapping said projections.
