Definitions

  • the respective desired wheel for example gear wheel, sprocket or toothed belt wheel
  • the respective desired wheel can be produced from a preform depending on intended traction means, so that it is possible to prefabricate corresponding preforms independently of the final tooth geometry, thereby responding more quickly to customer demand can, in which only the appropriate deformation in the final tooth geometry is required. It is thus possible to produce these preforms in stock, so that production bottlenecks can be compensated for by corresponding pre-production in times of lower capacity utilization.
  • the invention is thus to be seen in the fact that either the finished tooth contour of the chain or gear or the finished tooth contour of a toothed belt wheel is produced from the raw contours.
  • FIGS. 1 and 2 show a preform 1 for producing a multiple wheel 2 for a traction mechanism drive.
  • traction drives are, for example, chain drives or belt drives (belt drive).
  • the production of sintered components comprises the process steps mixing the powder, optionally with additives and auxiliaries, powder compaction into a green compact, sintering of the green compact, optionally calibration and / or densification of the sintered structural part.
  • the preform 1 is symmetrical with respect to the tooth geometry 5, there is also the possibility that the extent of the oversize of the rough contour 17 with respect to the sprocket contour 16 on the left tooth flank is different from the right flank.
  • the single wheel 3 is formed in this variant as a sprocket, but can also be a tooth 0 rad.
  • This single wheel preferably already has its final shape prior to forming the teeth 10 of the second single wheel 4.
