Definitions

  • the invention relates to a carrier plate for lamellar grinding wheels according to the preamble of claim 1.
  • EP 1 249 310 B1 is a carrier plate for lamellar grinding wheels in which the hub projecting inwards from the inner part has an internal thread for screwing onto the threaded shaft of the drive machine.
  • a shoulder-like depression is provided into which a shoulder of a drive plate engages, whereby the carrier plate is centered on the shaft.
  • DE 1 761 917 U shows and describes a cleaning or polishing disk (centering disk) with a ring cushion as a passage for air to be cooled, axially protruding from the centering disk tongues which serve to guide the air.
  • a support plate with the features of the preamble of present claim 1 is known in which the opening slots in the cup or dome-shaped inner part are separated by walls which form between the opening slots and the hub drain channels for grinding dust, the are formed as spiral sections and extend from the opening slots to the hub.
  • the invention has for its object to provide a carrier plate available, which causes over the prior art, despite simplified construction optimal cooling during operation of the disk grinding wheel.
  • this object is achieved in that are formed on the inside of the conical ring between the opening slots Lucasablenkfiügel, which are limited in their longitudinal extent to the longitudinal edges of the opening slots.
  • the Luftablenkfiügel go from the trailing in the direction of rotation of the support plate longitudinal edge of the opening slots.

  • FIG. 4 is a slightly perspective view of the bottom view of FIG. 3;
  • Figure 5 shows a variant of Figure 1
  • FIG. 6 shows a section corresponding to FIG. 2 in the plane VI-VI of FIG. 5.
  • the figures show a circular support plate 10 for lamella grinding wheels, which is integrally made of plastic, for. B. of polyamide and preferably of ABS, since this material has sufficient elasticity and a long life and is food safe.
  • the support plate 10 is composed of a dome-shaped inner part 12 and an outer flange 14.
  • a hub 16 is formed with internal thread 18, which allows a screwing on a threaded shaft of a drive machine.
  • the hub 16 extends within the dome-shaped inner part 12 in the axial direction substantially over the entire depth t of the conical inner side 20 of the inner part 12 (see Figures 2 and 6).
  • a central recess 24 is incorporated in the flat central region 22 of the inner part 12, which - as explained in EP 1 249 310 Bl - serves for the centering engagement of a drive plate.
  • the dome-shaped inner part 12 has a conical ring 26 which adjoins the central region 22 and forms the transition to the outer flange 14.
  • the outer flange 14 is used in a known manner for the fixation of abrasive slats that can be glued to the flat, inwardly facing annular portion 28.
  • the conical ring 26 of the dome-shaped inner part 12 are distributed over the circumference uniformly rectangular opening slots 30 incorporated, which extend obliquely to the radial direction.

Abstract

L'invention concerne une plaque de support pour meules à lamelles, comprenant un élément intérieur en forme de dôme (12) sur lequel est formé un moyeu (16) destiné à être fixé sur un arbre d'un moteur d'entraînement, ainsi qu'une bride extérieure (14) servant à fixer des lamelles de meules et reliée à l'élément intérieur en forme de dôme (12) par l'intermédiaire d'une bague conique (26) réalisée sur ce dernier. Sur ladite bague sont ménagées pour le passage de l'air des ouvertures en forme de fente (30) réparties sur sa circonférence et obliques par rapport à la direction radiale. Sur la face intérieure (20) de la bague conique (26), entre les ouvertures en forme de fente (30), sont réalisées des ailettes de déviation de l'air (32) qui sont adjacentes sur toute leur longueur à un des deux bords longitudinaux (34) des ouvertures en forme de fente (30) obliques rectangulaires, et dont l'étendue longitudinale est limitée sur le bord longitudinal (34) adjacent.
