Definitions

  • the invention relates to a cutter head for cutters, consisting of several, optionally together with washers axially braced as a package, inserted on a profiled shaft and positively locked to the shaft by means of a sickle knife, and several eccentrically arranged on the shaft and, together with the sickle knives, disc-shaped balancing weights clamped in the package.
  • Cutter heads made from sickle knives cause considerable, dynamic imbalances in cutters, which are detrimental to both the smooth running of the machine and the life of the knife shaft bearing, provided they are used unbalanced. For this reason, the cutter heads should always be balanced before use.
  • each individual sickle knife is provided with a counterweight, so that the center of mass of this knife lies in the axis of rotation when the knife package is later assembled.
  • a satisfactorily balanced cutter head can be built up.
  • the M es- serkopf by a sickle knives each associated additional weights is difficult and is therefore dangerous to handle.
  • each sickle knife is assigned a disc-shaped, adjustable balancing ring.
  • two rotatable adjusting rings are therefore arranged on the knife shaft.
  • the adjusting rings assigned to each sickle knife increase the weight of the cutter head considerably. Since the compensating rings are arranged directly one above the other, i.e. practically in one plane, they can only compensate for the static imbalance. However, it is known that a cutter cannot be smoothly running without compensating for the dynamic imbalance.
  • the invention has for its object to provide a cutter head for cutters that is simple in construction, light in weight and dynamically balanced.
  • a balance weight with a fixed center of mass is arranged in a form-fitting manner only in two axially offset planes lying on both sides of the knife package center, each balance weight with respect to its mass, its center of gravity and its angular position is matched to the resulting unbalance of the knife package effective in its plane.
  • the dynamic imbalance of the cutter package is eliminated with only two counterweights. This means that the total weight of the cutter head is not significantly increased by the counterweights.
  • the unbalance moment can be calculated in the planes in which the counterweights are positioned. It is therefore possible to determine the angular position and size of the counterweight from the start. The user of the cutter can therefore complete the cutter head without having to measure the entire cutter head on a balancing device.
  • the full compensation of the dynamic imbalance is lost. This fact can be taken into account from the outset by accepting a certain dynamic imbalance when new and the full compensation only after repeated grinding and thus reducing the weight of the individual sickle knives and at the end of the life of the sickle knife a certain dynamic imbalance again Purchase is taken.
  • the acceptance of the low dynamic unbalance during the life of the sickle knife can be avoided according to one embodiment of the invention in that the counterweights carry one or more detachable additional masses.
  • the additional masses can be held in recesses, in particular holes in the counterweights.
  • the additional weight is removed from the central recess, after further sanding, the two outer additional weights are removed and the medium additional weight is reinstalled and at the end of the service life, the third weight is also removed.
  • an untrained operator can keep the cutter head in a dynamically balanced state.
  • the cutter head consists of a profiled shaft with stop flange 1, a first disc-shaped counterweight 2, four sickle knives 3, 3.1, 3.2, 3.3, with spacers 4, 4.1, 4.2 arranged in between, which can correspond in their axial thickness to the disc-shaped counterweight 2, one second disc-shaped balance weight 5 and a nut 6.
  • the disc-shaped balance weights 2, 5 sit positively against rotation and radially immovable on the shaft.
  • the sickle knives 3, 3.1, 3.2, 3.3 have elongated holes 7, 7.1, 7.2, 7.3, so that they are non-rotatably held on the shaft, but are adjustable according to their degree of wear.
  • the center of gravity of the disc-shaped balance weights on the outside of the package is eccentric. Its angular position depends on the resulting unbalanced knife set effective in the levels. Since the direction of the unbalance does not change significantly with the wear of the crescent-shaped knives 3, 3.1, 3.2, 3.3, the angular position of the center of gravity, once defined, can be retained. To compensate for the decreasing mass, the additional masses 8, 8.1, 8.2 seated in the recesses can be removed. In this way, the cutter head can be kept in a dynamically balanced state throughout the entire service life of the cutter set.
