Definitions

  • the present invention relates to a separation and Support element to a tool holder to a Soil milling machine according to the preamble of Claim 1.
  • Patent No. CH 687 445 shows an example of a floor milling machine smaller Art.
  • the actual tool holder is mostly like one Thread spool built up on the flanges peripheral and generally two to parallel to the core eight shafts are attached, on which tools e.g. Milling wheels can be rotated loosely. If the tool holder turns, the tools on the waves by the centrifugal force outside held. If this tool holder during the Rotational movement of a surface, its plane to the axis of the tool holder is arranged in parallel approximated, these tools strike on the working soil resp. first on possibly existing increases. This serve offset them in a rotational motion. With the power that is to be applied to the inertia of the still To overcome tools, the area is processed. Bumps are leveled and / or a thin one Layer of the surface is removed.
  • the shafts in the two flanges can be rotated loosely stored. End covers or others Fasteners keep the shafts within Flanges in which they are stored.
  • Patent No. CH 1998 0067/98 represents a tool holder of this kind in front. Wear occurs both on tools and Waves, as well as on the holes in the flanges, in where the waves are held on.
  • the present invention now addresses the Task, separation and support elements into one Tool holder of the type mentioned at the beginning improve that even if only a few Tools in use are the dynamic imbalance of the Tool holder remains within reasonable limits and that Arrangement of tools on site depending on the The needs of each application freely determined can be.
  • Tool holder 2 as shown in Fig. 1 are one fixed from a central tube 6 and two at its Ends of welded flanges 5 existing Welded construction.
  • the central tube 6 can be a round, hexagonal or other polygonal Have tube profile.
  • flanges 5 are Recording the waves 4 on a circle with radius x Bores 10 are provided for receiving them.
  • Shafts 4 are the tools 3 as shown in FIG. 4 assembled and thus form a milling drum 1.
  • Such Milling drums are used for leveling concrete and Asphalt surfaces used. Often these are Machines also for the removal of Street drawings and rubber residues from tires Airplane runways used.
  • the milling tools 3 are large on the shafts 4 Clearance (difference between D4 and D3, Fig 5) mounted, so that they can move freely.
  • Milling tools 3 By the rotation the milling drum 1 in the “R” direction Milling tools 3 by touching the floor “B” in an opposite direction of rotation "r” is offset. There before this contact, it is relative to shaft 4 not move, this "nudge” causes the Machining of surface "B” triggered by the in the milling tools 3 stored inertia energy.
  • a separating and supporting elements 20 and 21 of the featured are always for one Tool holder 2, which consists of two flanges 5 and one central tube 6 is used (Fig 1).
  • the Use of a simple separating and supporting element 20 as shown in Fig. 6 has the advantage that one the distances a, b and c (Fig 2) for the milling tools 3 can adapt to the respective requirements.
  • the simple separating and supporting element 20 is on one of the Waves 4 postponed. It is in the axial direction freely to and fro between the two flanges 5 move. This allows each of the shafts 4 in a large area in any order Milling tools 3 and separating and supporting elements 20 and 21 alternate.
  • double separating and supporting elements ensures that there is no imbalance.
  • Simple and double separating and supporting elements can be on one Milling drum 1 together with the milling tools 3 in free sequence on the waves 4 are used.
