  • an oscillatory motion ie a Periodic reciprocating motion or - acceleration can be superimposed in the circumferential direction
  • Such vibrations can lead to a mutual abutment of the compressor rollers together with corresponding noise and also damage to the compressor rollers or suspension components for the compressor rollers.
  • a soil compactor with two such in the direction of the roll rotation axis successively arranged compressor rolls is from the EP 0 945 187 A2 known.
  • the two compressor rolls each have a tubular roll shell, on the inner peripheral surface of which two axial spaced-apart, essentially identically designed or identically dimensioned roll disks are connected.
  • the two roller discs are surrounded by a roller rotation axis surrounding or Concentrically arranged hub tube connected to each other. All assemblies to be provided in the interior of the two compressor rolls must be accommodated in the interior surrounded by the two hub pipes.
  • a compactor roller in particular for a soil compactor with at least one roller divided in the direction of a roller rotation axis, comprising a roller shell surrounding a roller rotation axis and elongated in the direction of the roller rotation axis and in the roll interior surrounded by the roll shell at least one with the roll shell at its Inner peripheral surface connected roll plate.

  • the roll plate 18, which, as well as substantially all other components or assemblies of the compacting roll 10 shown in the figures, is preferably constructed of steel material has a thickness of at least 40 mm.
  • a stiffening arrangement generally designated 28 may be provided in the roller interior 14.
  • the stiffening assembly 28 includes a stiffening ring 30, which is located closer to an axial end portion 32 of the roll shell 12, as at the axial end portion 16, in the vicinity of the roller plate 18 is positioned. This in turn means that the roller disc 18 has a greater axial distance to the axial end portion 32 of the roll shell 12, as compared to the axial end portion 16 thereof.
  • the stiffening ring 30 comprises an annular body 34 which, at two with respect to the roller rotational axis A opposite first peripheral portions 36, starting from its outer peripheral portion 38, a greater radial extent radially inward, as lying in between the first peripheral portions 36 second peripheral regions 40.
  • first circumferential portions 36 with greater radial extent of the annular body 34 is formed with a radial extent which is smaller than the radial extent of the disk body 20 of the roller plate 18, in particular less than 50% of the radius of the stiffening ring 30, preferably less than 30% of this radius.
  • the central opening 22 formed in the roller disc 18, starting from the roller turning axis A has a significantly smaller radial extent than a central opening 42 formed in the stiffening ring 30.
  • the stiffening ring 30 is connected with its outer peripheral region 40, for example by welding to the inner peripheral surface 26 of the roll shell 12.
  • stiffening assembly is provided between the roller plate 18 and the stiffening ring 30 .
  • This comprises two on both sides of the roller rotation axis A, in the direction of this roller rotation axis A extending parallel to each other and to the roller rotation axis A substantially the same distance having first stiffening plates 46.
  • Each of the first stiffening plates 46 is in a first axial end portion 48 thereof to the roller plate 18, for example connected by welding, wherein the two radial end portions 50, 52 of the first stiffening plates 46 in the region of the outer peripheral portion 24 of the roller plate 18 are.
  • these radial end portions 50, 52 of the first stiffener plates 46 extend in the direction of the roll rotation axis A substantially parallel thereto along the inner circumferential surface 26 of the roll mantle 12 and are bonded thereto by welding.
  • the first stiffening plates 46 each have a connecting web 56, 58 in their two radial end regions 50, 52.

  • a weld joint is made along the entire abutment region, for example, provided by substantially uninterrupted continuous Welds or spaced apart weld sections or welds. Also, where the first stiffening plates 46 abut with their radial end portions 50, 52 on the inner peripheral surface 26 of the roll shell 12 or are connected thereto, preferably over the entire axial extent of the first stiffening plates 46, a welded connection is made.
  • a second stiffening plate 60 is provided between the two first stiffening plates 46. This has both in the radial direction, as well as in the axial direction a significantly shorter extent than the first stiffening plates 46, so that it is positioned substantially only adjacent to the roll plate 18 and is connected in this area with the roll plate 18 by welding.
