Definitions

  • this tooth / tooth holder assembly has a free surface located between the neck of the tooth and the upper edge of the main part of the tooth holder, and on which the bending and twisting forces are very marked.
  • - Figures 5 and 6 show a tooth on which the bending forces have been taken up according to the prior art and according to the present invention
  • - Figure 7 shows another preferred embodiment of a tooth / tooth holder assembly welded to a milling head according to the invention.
  • the tooth holder has two parts: a rear part 1 adaptable in depending on the type of milling head and a main part of the universal saddle 2 capable of carrying the tooth 6.
  • the length of the universal main part 2 is clearly greater than that of the rear part 1.
  • This particular form of attachment advantageously allows faster replacement of the universal main part which, of part.3 of the tooth holder, undergoes the most significant wear. Indeed, on the one hand the correct repositioning during the replacement of this part of the tooth holder is facilitated by the fitting having the pyramidal shape described above and on the other hand, the reduction in the weld section makes it possible to disassemble then quickly reassemble the universal main part 2 of the rear part 1.
  • the joining means between the main universal part 2 and the tooth 6 preferably consist of ribs 20 of the tooth holder which engage in grooves 21 of corresponding shape of the tooth 6. These grooves end with lateral pins 4 which engage in cavities 5 of a corresponding shape of the tooth 6.
  • the rear part 1 of the tooth holder is preferably made according to the current forms of the state of the art. It is in the form of a nose to be welded with or without reinforcement making it possible to adapt to existing milling heads. This means, in particular, that the rear part 1 has conventionally two chamfers 15 of large section as for the tooth holders made in one piece according to the prior art.
  • the rear part 1 of the tooth holder is extended by two lugs 16 whose spacing is equal to the thickness of the milling head 17 and which are each welded to one of the faces of the milling head 17.
  • This type of more robust tooth holder is called "double leg".
