Definitions

  • the invention relates to a centrifugal wheel for devices for mechanical surface treatment by spin coating Abrasive with an outer main wheel with at least a disc attached blades spaced from the hub the centrifugal wheel are arranged, and with one in the hub area arranged, coaxial and co-rotating with the main wheel Impeller.
  • centrifugal wheel is already known from DE 195 36 723 C2 known.
  • the impeller wheel of this well-known centrifugal wheel also has blades that the in the hub area of the Blasting media fed to the impeller wheel radially outwards to the Guide the blades of the main centrifugal wheel.
  • the impeller has doing the task of hitting the impeller wheel Blasting media start rotating at an early stage offset. This makes the spray pattern more uniform and it there is less wear on the centrifugal wheel.
  • the present invention is based on the object To improve the centrifugal wheel of the type mentioned at the beginning, that the spray pattern becomes even more even.
  • Impeller wheel an impeller wheel disk provided with blades has, the blades of the impeller in one Angle aligned with the radial direction of the impeller wheel are.
  • This arrangement of the blades of the impeller wheel is a better transfer of the abrasive to the blades of the main wheel possible.
  • the abrasive also hits evenly on the entire surface of the main blades on, so that these blades are in contrast to the known ones Wear centrifugal wheels much more evenly.
  • the blades of the main wheel and impeller either straight or curved.
  • the Buckets perpendicular to the disc can at least to be arranged inclined in some areas.
  • the Blade of the main wheel and / or the impeller wheel between two disks can be arranged.
  • this known per se Structure of the centrifugal wheel is particularly high stability reached.
  • the provision of a cover plate leads to a higher pressure and better guidance of the abrasive.
  • Impeller wheel of a centrifugal wheel based on the drawing described in more detail.
  • Fig. 1 shows a top view of an impeller 10 with a Impeller wheel disk 11 and blades 12 arranged thereon.
  • the blades 12 are one in particular also seen from Fig. 2 annular disc 13 partially covered.
  • the blades 12 do not extend entirely up to the hub area of the impeller wheel disk 11, so that there There is room for an abrasive feed line.
  • the abrasive feed line can thus go up to just above the impeller wheel 11 are guided so that the blasting agent through the Rotation of the impeller wheel 10 in the direction of arrow 15 (FIG. 1) from Hub area of the impeller wheel from to not shown here Main wheel is worn radially outwards.
  • the blades 12 are at an angle ⁇ to radial direction 14 of the impeller 10 aligned, whereby a very even transfer of the abrasive reached the blades of the main wheel, not shown here becomes.
  • the blades 12 are approximately in the side view trapezoidal. You will be heading towards the hub the impeller wheel 12 lower.
