Definitions

  • the invention relates to a tool for processing materials.
  • the invention relates to a tool for processing materials, preferably a grinding wheel, with a carrier body with bushings, wherein the tool has a hub for receiving a drive shaft, and means for covering the bushings.
  • the carrier body is configured with at least two feedthroughs, which preferably extend from the inner region of the carrier body, ie from the edge region of the carrier body lying at the hub, in the direction of the outer edge of the carrier body, ie towards the jacket body, wherein, preferably in each sectional plane of the carrier body, the ratio A D / A T is greater than 1, preferably greater than 2, preferably greater than 3 and preferably greater than 4, from the sum of the areas A D forming the lead body material and the area A T forming the carrier body material.
  • the areas forming the leadthroughs A D are therefore greater in total than the surface of the material forming the support body A T , and preferably significantly larger.
  • At least one of the short sides in the plan view can be at least partially circular-segment-shaped, for example concentric with the outer circumference of the lateral surface.
  • the two long sides of the respective bushing are designed to be of equal length, so that the bushings of the carrier body in this embodiment appear substantially annular segment-shaped.
  • the quadrangular passages are distorted or bent about a point located outside the respective feedthrough so that the long sides of the feedthroughs are substantially arcuate or preferably circular segmented in plan view.
  • the spokes emerging from the material of this embodiment remaining between adjacent feedthroughs are thus arcuately curved and preferably circularly curved and extend in the inner region of the carrier body, ie substantially initially radially outwardly from the hub or axle receptacle, and then by their curvature to experience a kind of asymptotic approach towards the scope of the tool.
  • the degree or extent of the approach of the spokes to the circumference of the tool is different selectable and, as it were, an essential parameter for the radial elasticity of the tool.
  • Fig. 2 to 5 show schematic sectional views of grinding wheels according to the present invention, wherein for ease of explanation, the tools according to the invention along a section line that the section line XX of Fig. 1 corresponds, are cut.
  • like reference numerals designate corresponding elements or elements with corresponding functions.

Claims (10)

  1. Outil en vue de l'usinage de matériaux, notamment une meule avec une géométrie extérieure cylindrosymétrique pour l'essentiel par rapport à rapport à un axe de rotation, un moyeu situé à l'intérieur (5), à travers le centre duquel l'axe de rotation s'étend centriquement, un corps de chemise situé à l'extérieur, concentriquement à celui-ci (4), et au moins un corps de support (1) disposé entre le moyeu et le corps de chemise, qui est de préférence en une pièce avec le moyeu (A) et/ou le corps de chemise, le corps de support (1) étant aménagé avec au moins deux passages (2), qui s'étendent de la zone intérieure du corps de support vers le corps de chemise (4),
    caractérisé en ce
    qu'au moins quelques-uns des passages (2) sont recouverts complètement pour l'essentiel sur au moins une des deux surfaces de recouvrement cylindrique du corps de support (1) par au moins un élément de recouvrement (10), l'élément de recouvrement (10) étant relié à ceux-ci au moins dans la zone intérieure du corps de support et/ou dans la zone du moyeu mécaniquement, par adhérence et/ou par adhésion par matière.
  2. Outil selon la revendication 1, caractérisé en ce que l'élément de recouvrement (10) est fabriqué en un matériau, qui est sélectionné à partir d'un groupe, qui contient des plastiques, des métaux légers, des matériaux composites en fibre de verre ou en fibre de carbone, du tissu et du tissu enduit, des films, des matériaux composites armés de tissu, des combinaisons des matériaux précédents et d'autres matériaux similaires.
  3. Outil selon une quelconque des revendications précédentes, caractérisé en ce que l'élément de recouvrement (10) est disposé de manière concentrique sur la surface de recouvrement cylindrique de l'outil et en ce que le rayon extérieur de l'élément de recouvrement (10) est inférieur au rayon du corps de chemise (4), de sorte qu'entre l'élément de recouvrement (10) et le corps de chemise (4), est défini un espace libre (12) s'étendant dans une direction radiale.
  4. Outil selon une quelconque des revendications précédentes, caractérisé en ce que le rapport AD/AT de la surface AD constituant les passages (2) et de la surface AT constituant le matériau du corps de support est ≥ 1, de préférence ≥ 2, de préférence ≥ 3 et de préférence ≥ 4.
  5. Outil selon une quelconque des revendications précédentes, caractérisé en ce que la totalité des passages (2) du corps de support est recouverte entièrement par l'élément de recouvrement (10).
  6. Outil selon une quelconque des revendications précédentes, caractérisé en ce que la liaison de l'élément de recouvrement (10) avec le corps de support (1) et/ou le moyeu (5) est réalisée par un serrage de l'élément de recouvrement (10) contre le corps de support (1) et/ou le moyeu (5) et/ou par des éléments de fixation.
  7. Outil selon une quelconque des revendications précédentes, caractérisé en ce que l'élément de recouvrement (10) est relié pour l'essentiel sur la surface complète avec le corps de support (1).
  8. Outil selon une quelconque des revendications précédentes, caractérisé en ce que le matériau en vue de l'établissement d'une liaison par combinaison de matière est une colle, de préférence une colle à élasticité permanente et notamment une colle à base de résine, de plastique ou de silicone.
  9. Outil selon une quelconque des revendications précédentes, caractérisé en ce qu'au moins quelques-uns des passages (2) sont remplis de matière de charge (20).
  10. Outil selon la revendication 9, la matière de charge (20) étant sélectionnée à partir d'un groupe, qui contient des plastiques et des métaux expansés, notamment des mousses de polyuréthane, des mousses de PVC ou des mousses de polystyrène, de l'aluminium expansé et d'autres matériaux similaires.
