Definitions

  • the invention relates to a centrifugal wheel for devices for mechanical surface treatment with several, at least a disc-shaped, curved blades for discharge an abrasive.
  • centrifugal wheels in the direction of rotation of the centrifugal wheel in generally concave-curved blades have turned out to be the uniformity of the abrasive discharge and the susceptibility to wear the blast wheel in blasting systems that by spin-coating one usually made of metal particles existing blasting media a cleaning of surfaces, make rolled products, in particular, proven. at Shot blasting machines have to turn these centrifugal wheels partially to the right, So clockwise, and partially left, so counterclockwise, rotate. So it was for the manufacturers previously necessary for bicycles with curved blades, to keep both left and right wheels. Also for The maintenance and retrofitting of a system is different Wheel types or blade types required.
  • the present invention is based on the object Propose a centrifugal wheel quickly and easily by one Clockwise rotation can be switched to counterclockwise rotation.
  • the task is carried out with a centrifugal wheel for devices mechanical surface treatment with several, at least a disc-shaped, curved blades for discharge solved an abrasive, which is characterized according to the invention is that the blades are detachable at the least a disc are arranged, being in a basic position and in one by 180 ° with respect to their mean Longitudinal axis rotated position can be arranged on the disc, so that by turning the blades a blast wheel for the Counterclockwise rotation or for clockwise rotation can be produced.
  • the centrifugal wheel according to the invention is therefore a quick changeover from a right-hand wheel to a left-hand wheel and vice versa possible without removing the centrifugal wheel from the system must become.
  • Centrifugal wheel types are available.
  • the blades are absolutely symmetrical, so that they are the same Beam properties for both clockwise and clockwise rotation Turn left.
  • the blades can be provided with projections on their long sides be inserted in grooves in the disc. there can the grooves towards the outer circumference of the Narrow the disc so that it closes when the centrifugal wheel is rotating a clamp connection between the blades and the disc comes.
  • the grooves and the projections are dovetail-shaped Have cross-section.
  • knobs can be made on the groove base an elastic material, such as rubber, to increase friction between the projections of the blades and the Grooves can be arranged. So that the blades are during the Installation of the centrifugal wheel against both an axial and secured against radial falling out.
  • the blades are arranged between two disks.
  • the blades can between two disks, the main driven disk and one Cover plate, be arranged, the blades on both Disks can be fastened by means of projections which can be inserted into grooves could be.
  • the cover plate increases the stability of the centrifugal wheel. But you can also use centrifugal wheels with only one Disc can be used.
  • the centrifugal wheel 10 shown in FIG. 1 has a driven one Disc 11 and arranged thereon, in the direction of rotation 12 of the Blower wheel 10 concavely curved blades 13.
  • the for this purpose blades have visible on their long sides from FIG. 2 Projections 15 on the in radially directed grooves 16 (Fig. 1, 3) of the disc 11 can be inserted.
  • 14 can both the projections 15 and the grooves 16 a dovetail-shaped Have cross section, so that the blades 13 after the Insert the projections 15 in the grooves 16 no longer this can fall out in the axial direction of the wheel 10.
  • the blades 13 are between the main disc 11 and a cover plate 14, the Attachment to both disks 11, 14 via projections 15 and corresponding grooves 16 takes place.
  • the two disks 11 and 14 are with each other via spacers 18 between the blades 13 connected.
  • the perspective view of the centrifugal wheel 10 according to FIG. 3 illustrates in particular the appearance of the projections 15 the blades 13. They are T-shaped, the T-web 15.1 as Stop on the outer boundary 16.1 of the grooves 16 is used. On the other three sides are the protrusions 15 from a cover 20 surround the penetration of material particles prevent in the grooves 16.
