Definitions

  • the invention relates to a rotor for beater mills with axially parallel rows of impact hammers, which are arranged pivotably in pairs on pipes, which are secured in their position between rotor disks by bolts which penetrate the pipes in their axial direction and are fixed in the outer rotor disks.
  • the racket packs which are arranged between two adjacent rotor disks and consist of a tube and the beaters supported thereon, are stored in the rotor disks via the securing bolts which enter the tubes are inserted.
  • the length of the tubes corresponds to the clear distance between adjacent rotor disks.
  • the invention is based on the object of avoiding these disadvantages of the known racket mill in that the tubes themselves are mounted in the rotor disks in such a way that they cannot fall out of the bearing in the rotational position of the rotor selected when removing or installing the racket packages, while the bolts inserted into the tubes only serve to secure the racket packages in the bearing for other rotor turning positions.
  • the tubes are suspended in bearing shells provided on the rotor disks and open towards the rotor axis and are secured in the suspended position by the bolts.
  • a racket mill is known, however, in which the rackets are arranged on strong tubular bearing bodies. However, these are only supported at one end in a rotor disk by being pushed from this side into a corresponding rotation of the rotor disk. The other end, on which in each case only one racket is mounted, does not engage in a rotor disk and is only supported in it via the securing bolts which are guided through all the tubular bearing bodies.
  • This design is very complicated and cumbersome to handle because, in contrast to the subject matter of the invention, a separate bearing body is provided for each individual racket instead of a racket package.
  • the beaters in a row are mounted on a bolt which extends over the entire length of the rotor and is hooked into hook-shaped recesses in the rotor disks. It is fixed in these recesses by fillers, which in turn are secured by two-part clamps surrounding the rotor disks.
  • all rackets in a row must be removed at the same time, and the clamps securing the filler pieces of the other racket rows must be removed, so that there is a risk that when a row of clubs is removed there are also others Unintentionally remove rows of bats from the rotor. In any case, this is also a very complicated design.
  • the ends of the tubes are attached laterally to the rotor disks in question, e.g. welded-on bearing bodies which are open towards the rotor axis. If the axes are to be supported again between their ends, hook-shaped radial bearing plates are provided between each two adjacent rotor disks, which are fastened to the hollow shaft surrounding the rotor axis, e.g. are welded onto them.
  • the rotor consists of a hollow shaft 1 and welded-on rotor disks 2. Hook-shaped support plates 3 are fastened to the hollow shaft between two rotor disks. Bearing bodies 4 which are open toward the rotor axis are arranged on the mutually facing side surfaces of the rotor disks 2. The support plates 3 have lateral recesses 5, which lead into closed storage bays 6. The rotor disks 2 have bores 7 centrally to the bearing bodies 4 through the securing bolts 8 are introduced.
  • Rackets are suspended in the bearing body 4 and the bearing bays 6 and consist of a tubular axis 9, beaters 10 pivotably arranged thereon and spacer bushes 11. The racket packages 9, 10, 11 are fixed in position by the securing bolts 8.
  • the racket packages 9, 10, 11 are installed and removed when, according to FIG. 2, they are located approximately in the lower right quadrant, in which the tubular axes 9 cannot fall out of the bearing bodies 4 and the bearing bays 6 even when the safety bolt 8 is pulled out . You can therefore remove the worn racket packs individually from the rotor after pulling out the relevant safety bolt and hang in place of their new one, without additional holding means being required until they are finally secured by inserting the safety bolt.
