Definitions

  • the invention relates to a cutter head for cutters with at least two cutter knives arranged in mass balance with respect to its axis of rotation, each of which has an elongated hole on the foot side and at least one cutting section, with a shaft receiving disk with a central opening in the form of a regular polygon, and with one on opposite parallel longitudinal edges the shaft receiving disc formed toothing, which is assigned a toothing on opposite parallel longitudinal edges of the cutter knife for the engagement.
  • the shaft receiving disks have a longitudinal recess with opposite parallel inner edges which are provided with a toothing.
  • the foot of the respective cutter knife can be used in this longitudinal recess, which is provided with a corresponding toothing on its opposite parallel outer longitudinal edges.
  • This toothing makes it possible to achieve a radial knife adjustment, but the axial length of the knife head is very large, since the shaft receiving disk with half its thickness is present between two axially adjacent cutter knives.
  • the object on which the invention is based is to design the cutter head of the generic type in such a way that a form-fitting, radially adjustable positioning and secure holding of the cutter knife of the cutter head is ensured even if the cutter knives are arranged axially directly against one another.
  • the toothing of the shaft receiving disc is formed on its outer longitudinal edges and the toothing on the cutter knife on the longitudinal edges of its elongated hole, that the thickness of the shaft receiving disc is not greater than the depth of the elongated hole in the cutter knife , and that the outer longitudinal edges of the shaft receiving disc are shorter than the longitudinal edges of the elongated hole.
  • the cutter knives can be adjusted in the radial direction according to the tooth pitch and taken into account with respect to the required mass balance, and fixed with respect to the drive shaft, whereby to achieve the minimum axial length, the cutter knives can be arranged aixally directly against one another, since the shaft receiving disc in the slot of the assigned cutter knife is recorded and corresponds in its thickness to the depth of the elongated hole substantially.
  • the cutter knives are fixed on the drive shaft through the appropriately designed opening in the shaft receiving disk, the cutter knives can be made larger on the foot side, as a result of which a larger clamping surface and thus a more stable mounting on the drive shaft can be achieved.
  • the risk of knife breakage is reduced due to the large cross section during the transition to the cutting section.
  • the shaft receiving discs can be square, so that toothings with a different pitch can also be attached to the transverse edges, which enables a radial infeed of, for example, 3 mm, 1.5 mm and 0.75 mm.
  • the cutter head shown in FIGS. 1 and 2 consists of three cutter knives A, B and C, which are arranged in an angular position of 120 ° to each other on a drive shaft 9 'axially directly against each other and are secured on the shaft head 13 by a lock nut 12.
  • the cutter knife 1 shown in detail in FIG. 3 corresponds in its design to the cutter knife A, B or C of FIG. 1.
  • the cutter knife 1 has cutting sections 2, 3, 4 and 5.
  • In the area of the knife foot 6 there is an elongated hole 7 with opposing ones parallel inner longitudinal edges formed, which are provided with an internal toothing 10.
  • a shaft receiving disc 8 with a central hexagonal opening 9 for receiving a drive shaft 9 'with a corresponding hexagonal profile has on its opposite parallel outer longitudinal edges an external toothing 11, which for engagement with the Toothing 10 is formed on the longitudinal edges of the elongated hole 7, whereby a radial insertion of the cutter knife 1 with respect to the central opening 9 of the shaft receiving disk 8 and thus with respect to the drive shaft 9 'around the intended tooth pitch is possible.
  • the longitudinal extent of the shaft receiving disc 8 is less than the extent of the elongated hole 7 in its longitudinal direction in order to ensure the radial adjustment over a certain longitudinal range, which is required by regrinding and balanced positioning of the cutter knife.
  • the thickness of the shaft receiving disk 8 corresponds essentially to the thickness of the cutter knife 1 in the area of its knife base 6, that is to say the depth of the elongated hole 7, so that when the shaft receiving disk 8 is arranged in the respective cutter knife 1 or A, B and C, the cutter head consists of compact components lying next to each other.
