Definitions

  • the present invention proposes a bearing disc for diamond tools of the kind used for the manufacture of circular saws for cutting stone materials and the like in which cuts having a particular shape and position are provided, suitable for damping and/or preventing vibrations when the tool is used.
  • the disc is stiffened by tensioning it in the area comprised approximately between a third and two thirds of the diameter of the disc itself.
  • the present invention proposes a bearing disc for diamond tools in which there is provided a plurality of conveniently placed cuts, being able to damp or prevent this phenomenon.
  • the bearing is made up of a conveniently thick metal disc, indicated as a whole by 1, to which the diamond portions (not illustrated in the figure) are welded connected with the edge and which has an axial hole, indicated by 2, for applying the disc to the shaft of a machine which may be a saw for cutting stones or another apparatus known in the art.
  • the invention is characterized in that on the disc there is a set of cuts suitable for damping both tangential and radial vibrations.
  • Both cuts 3 and cuts 4 in their end portion run curvilinearly, in particular they run on a line like a small semi-circumference.
  • Cuts 3 are staggered with respect to cuts 4, in the sense that a straight line passing through cuts 3 halves the area comprised between two external cuts 4.
  • Cuts 5 and 6 have the shape of a "Z" with the edges turned backwards and they are symmetric, in the sense that each cut 5 is the specular image of the corresponding cut 6, each pair of cuts 5 and 6 being placed between two consecutive external cuts 4.
  • the invention is characterized in that it provides for radial cuts near the outward diameter and the disc hub, one being staggered with another, and "Z"-shaped cuts, which are placed near the outward diameter.
  • the former have the function of damping tangential vibrations, whereas the latter damp both tangential and radial vibrations.
  • a bearing disc is thus obtained for diamond tools making the use of these tools much more practical and cheaper, being able to damp or eliminate vibrations almost completely.
