Definitions

  • the present invention concerns a carrier body for grinding tools having an inner hub ring surrounding a central bore for connecting the grinding tool to a rotary drive, and an outer casing ring for receiving a grinding means, in particular in the form of a galvanic coating, a grinding ring or a plurality of grinding segments.
  • the hub ring and the casing ring are connected together by way of a plurality of mutually spaced webs.
  • the invention further concerns a grinding tool comprising such a carrier body.
  • EP 2 641 696 A1 discloses a carrier body.
  • the aim set in the case of those carrier bodies is to save as much weight as possible and at the same time to make the carrier body as stable as possible.
  • the first aim is successfully achieved in the structure in accordance with EP 2 641 696 A1.
  • the carrier bodies of EP 2 641 696 A1 expand to an unwanted degree, in particular with an increasing speed of rotation.
  • the object of the invention is to provide a carrier body which is improved over the state of the art and which on the one hand is greatly reduced in weight and which on the other hand enjoys adequate strength in relation to centrifugal forces and adequate stiffness in relation to lateral forces.
  • the invention seeks to provide a grinding tool having such an improved carrier body.
  • the webs each have at least one respective opening.
  • a further great advantage is that the dynamic behaviour of the carrier body or a grinding tool including the carrier body can be influenced in specifically targeted fashion by the arrangement and the variation in the geometry of the webs and the at least one opening provided therein.
  • the strength and stiffness can be still further increased as described below.
  • a grinding tool having a carrier body according to the invention and a grinding means connected to the casing ring, in particular in the form of a galvanic coating, a grinding ring or a plurality of grinding segments.
