Definitions

  • the invention relates to a rotating milling machine for rock processing, especially for concrete, asphalt, masonry.
  • Such machines serve, among other things, walls, floors or roadways to mill or to mill grooves.
  • DE 196 31 659 and DE 196 34 514 succeeded for the first time.
  • the invention has for its object a significantly higher impact performance with smaller impact drive performance and with simpler, and therefore cheaper, lighter and to achieve a reliable construction.
  • the object is achieved in that for some or all Milling chisels an impact-inducing pendulum are provided in the milling drum are arranged all around.
  • a milling drum with external milling bits is turned, while inside the milling drum there is a pendulum shaft with pendulum on the outside rotates at different speeds and / or directions of rotation. From the relative speed of Milling drum and pendulum shaft as well as the number of pendulums results in the impact frequency.
  • the milling chisels are at their outer stop and cannot be reached by the pendulums there.
  • the milling bits are rotatably mounted or guided linearly and can be limited in their pendulum movement and linear movement by means of stop points, the inner stop defining the optimal impact position for the pendulum and the outer stop serving as a limit stop.
  • the pendulum shaft rotating inside the milling drum and equipped with pendulums rotates faster than the milling drum rotating on the outside. Pendulum shaft and milling drum have the same direction of rotation.
  • the impact frequency and impact performance is based on the number of pendulums and speed difference between milling drum and pendulum shaft and by choosing pendulum mass adjustable and shape. This provides an optimal opportunity to address certain Adapt individual cases and certain milling goods. It is similar to the game of billiards useful, anchor point and the geometries of the impact areas of pendulum and Milling chisel leading the resulting impact force through the chisel tip to train. Depending on the angle of impact, the struck ball (milling chisel) is in struck a different direction than the direction of the approaching ball (pendulum).
  • the drive power is further optimally used because the milling bits are one radial cutting plane even at the greatest intended cutting depth of an individual Cut only one milling chisel into the milled material, distributed over the circumference are arranged.
  • Milling bits adjacent in the axial direction can be used independently pendulum pendulum can be advantageously applied safely because the pendulum is the axial Have the extent of the milling cutter round they are working on.
  • the pendulum shaft 4 includes 8 stop points as limit position for the pendulum; In addition, there are possible damping or spring elements 7 on the End positions indicated.
  • the milling drum 5 rotates on the outside around the pendulum shaft 4. Both become in the same direction of rotation (clockwise), but independently of each other and with different speed driven.
  • the milling bits 2 are driven by the centrifugal force and / or (not shown) springs pressed outwards against outer stops 6. Only when working on the milled material 9, the milling chisels 2 can be pressed against their inner bearing 6 by the milling material 9. In this position, however, the pendulum 1 meets the milling cutter 2. At this moment the pendulum 1 moves at the point of impact in the direction 11, tangential to it Orbit. Due to the geometry of milling cutter 2 and pendulum 1 in the impact area there is approximately a resulting direction of impact force 10.
