Definitions

  • the invention relates to a grinding wheel according to the preamble of claim 1.
  • the stones may in particular be artificial stones, such as bricks, which, after their manufacture, are attached to their surface, e.g. may have ridges derived from cutting operations, which are the subsequent processing in the way and therefore to be machined.
  • the cutting wheel has a cutting means in its peripheral region, which has a working surface on a working side of a disk-shaped wheel body of the grinding wheel and is effective on this working side of the grinding wheel and accessible to the object to be machined.
  • the grinding wheel is rotated by a rotary drive, wherein the abrasive rotates in a ring zone.
  • this or these are moved on a conveyor track on the working side of the grinding wheel over so that they come into contact with the abrasive and machined.
  • This machining operation may be a grinding or milling operation.
  • grinding is used because this name is at least introduced in the brick industry.
  • a cutting wheel of the type specified is in the DE 101 62 425 A1 described.
  • This prior art grinding wheel has a radially outwardly extending from a bearing assembly wheel body on the working side a disc-shaped cover body with axial distance to the wheel body is mounted, arranged between the wheel body and the cover body conveying elements facing away from the working side by a hollow shaft of the bearing assembly Suction the side of the grinding wheel and convey it outwards towards the abrasive.
  • an air supply duct extends through a motor shaft designed as a hollow shaft. Due to the considerably long hollow shaft and due to a desired small construction not only a relatively small air supply cross section is available, but the air supply is relatively low due to the considerable length of the hollow shaft resulting line losses.
  • the invention has for its object to improve the air supply in a grinding wheel of the type specified. This object is solved by the features of claim 1. Advantageous developments of the invention are described in the subclaims.
  • the wheel body has axial inflow openings for the air in its area surrounding the bearing arrangement. Through these flow openings, air can flow out of the region arranged at the rear from the grinding wheel and surrounding the bearing arrangement. In this case, the air can be sucked through the flow openings or conveyed or pressed, depending on where the conveying elements are arranged with respect to the flow openings.
  • a particularly powerful construction results when the conveyor elements protrude from the rear of the wheel body.
  • the conveying elements cooperate directly with the air which is in the area surrounding the bearing arrangement and is in the standing state or in a low moving state than would be the case if the conveying elements were arranged in the rotating grinding wheel , as is the case in the prior art.

  • the inventive design leads to improved engine cooling, since the axially supplied air can coat the outer surface of the engine over a large area.
  • first conveying elements in addition to first conveying elements, second conveying elements can be provided which are offset radially outward with respect to the first conveying elements. It is also possible to provide only the second conveying elements instead of the first conveying elements, so that the latter can be omitted.
  • the promotion of air can be achieved by displacement effect or by suction.
  • the effectiveness is great when the dimension of the conveying elements extending substantially radially from the inside to the outside is relatively large. It is particularly advantageous if the z. B. formed by lateral projections conveyor elements extending from the peripheral region of the inflow outward to the cutting means or to a cutting agent-bearing slip ring, or extend into the area inside. Moreover, if the gaps formed between the approaches are axially closed on both sides, z. B. by a disc, arise between the wheel center and such a cover outwardly extending channels in which the air flow can form undisturbed and propagate.
  • the lateral approaches can z. B. be formed by rectangular in cross-section bars whose extending in the direction of rotation dimension is preferably the same.
  • the gaps or channels extending between the lugs have a width extending in the direction of rotation, which width increases continuously radially outward. This has an advantageous effect on the air flow in the delivery mode.
  • the z. B. by lateral projections formed conveying elements to the inner peripheral portion of the slip ring or, z. B. two-piece, also extend in the region of the slip ring, z. B. up to the arranged in its peripheral region grinding elements.
