Definitions

  • the invention relates to a rotor for impact or hammer mills with a shaft and a rotor body supported thereon, the rotor body being composed of several rotor disks welded together from cast steel, the widened, have contacting hubs.
  • a rotor for hammer mills which consists of disks is built on which four warts are placed over the circumference, adjacent warts are welded together so that four continuous, ledges connecting the panes result.
  • This well-known rotor, the only by four axially extending warts made of welded together Last is held together does not have sufficient strength.
  • a rotor for hammer mills which consists of individual disc sectors welded directly to the rotor shaft. Except that the welding of individual disc sectors with the rotor shaft is cumbersome, this type of attachment of the disc sectors there are strength problems on the rotor shaft.
  • Rotors for hammer breakers are known from DE-C 33 27 204 and DE-A 26 05 751, in which the individual disks are each rotatably attached to the rotor shaft are. This individual attachment of the disks on the rotor shaft is complex and leads to a risk of breakage if, for example, the individual panes a tongue and groove connection are attached.
  • the object of the invention is to provide a stable rotor body of the type specified To create kind of that in a simple way and in a simple way can be attached to the rotor shaft in such a way that there is no damage.
  • the inventive design of the rotor results in a stable rotor body, which is not to be guided on the shaft over its entire length needs, but is only supported at both ends on the shaft.
  • For the bearing of the rotor body on the shaft is therefore only a more precise turning of the rotor disks only partially necessary on the two end disks.
  • the rotor disks have a widened outer ring compared to the hub on both sides around the Half of what is narrower than the distance between adjacent outer wreaths for passing one Welding gun to the hubs is required.
  • Rotor is therefore in this preferred embodiment exclusively from the rotor disks manufactured in cast steel and is therefore very cheap to buy Manufacturing.
  • the parts that the form widened outer rim of the rotor disks welding the hubs to create planners Machining contact surfaces for the blow bars are only simple components are and also the production of the holes for the Dowel bolts can be made very precisely, superfluous the very complex processing of a finished Rotors across the entire width.
  • the rotors shown each consist of several in Cast steel rotor disks 1 manufactured with a middle cylindrical opening 2 and a surrounding this wider hub 3 are provided. On the outside They have edge depending on the type of intended on them Crushing tools (hammer 4, blow bars 5) wider bearing bodies 6 and 7. These are in the cases Fig. 1-8 so designed that between the bearing bodies of adjacent rotor disks 1 Gap 8 remains.
  • the hubs 3 of adjacent rotor disks 1 are on their outer edges by ring welds 9 firmly together connected. To produce these ring welds are against each other at the hubs 3 by dowel pins 10 centered and braced rotor disks slowly rotated, being fixed and by column 8 welding machines reaching to the hubs create the weld.
  • the welds After the welds have been made, they are used for final assembly in the hammer mill rotor shown in FIGS. 1 and 2 the hammers 4 held between the discs and their axes 11 are in the bearing body 6 of the end of the rotor in the continuous Receiving holes inserted, while in the 3 and 4 shown impact mill rotor the Blow bars 5 in the edge cutouts 12 from the outside used and by wedges 13 and pressure elements 14 pressed against the bearing body 7 serving for support become.
  • 5 to 8 illustrate that one can use rotor disks different hub width rotors different Can produce width so that with less Warehousing very narrowly differentiated offers possible are.
  • FIGS. 9 and 10 show, only two can Rotor disks 1 may be provided, optionally under Intermediate layer of a hub-like ring 3 ', in Modification of the invention on the disc edges 1 'of Rotor disks 1 axially parallel support beam 15 welded are.
  • the support beams are only after previous welding of the rotor-hub body attached so that even with this for rotors smaller impact mills provided version All-round welding, even automated, is possible.
