Definitions

  • the invention relates to a device and a method for prototype and small batch production of gears.
  • the tool for the pre-toothing and for the hard machining is designed and commissioned at process point 3. After determining the profile.
  • the manufacturing or delivery time for these tools is very lengthy and can be up to three months. Any change requests or manufacturing errors on the tool are only visible on first use and therefore inevitably lead to the necessary post-processing, for example stripping, regrinding or recoating of a hob. This is accompanied by several days or weeks lost production.
  • the Vorveriereen or hard fine machining should be done by generating grinding, a galvanically occupied dressing tool is required for this generating grinding, which carries the special profile shape of the toothing. Also for the preparation of such a dressing tool several weeks delivery time are necessary.
  • a profile-matched dressing tool and a universal dressing tool can be used, trained with the grinding worm line becomes. So here the special profile design is produced by the control of the grinding or dressing machine. This process eliminates the delivery time of the special tool. However, it is disadvantageous that several hours are required for dressing the grinding worm out of the cylindrical green body.
  • the steps of Vorveriereens or Hartfeinbehavs by profile grinding according to the process steps 3 and 6 of the aforementioned process sequence can also be done by means of a profile grinding process.
  • the inverse profile is applied to the grinding wheel and then transferred to the workpiece during grinding, whereby a simple type of movement such as, for example, a very slow linear movement with simultaneous rotation of the grinding wheel is sufficient.
  • the profile grinding is used to produce the pre-toothing, the complete tooth height must be formed.
  • the object of the present invention is to significantly reduce the production time of prototypes or small series with the lowest tooling costs.
  • gearless or pre-toothed and possibly hardened gears should be able to be processed.
  • this method should thereby be universally applicable, that with a grinding and a dressing tool all teeth with any profile modifications should be generated.
  • this object is initially achieved by a device having the features of claim 1.
  • a device for prototype and small batch production of gears is given to the hand, which has a disk-shaped dressing tool, which has on the one hand a asymmetric flank shape and a defined head radius according to a preferred embodiment.
  • the dressing tool has the same or different flank angle on its right and left cone flanks and a defined head radius. Both grinding wheels and profile grinding wheels can be dressed using this dressing tool.
  • This universally applicable dressing tool can be used independently of the module and pressure angle of the respective toothing. All profile modifications in the grinding tool can be realized here.
  • different numbers of gears can be generated from a cylindrical green body. So you can completely dispense with the order pre-profiled grinding worms, which - as previously stated - have a longer delivery time.
  • the device according to the invention undergoes advantageous embodiments by the subsequent to the main claim subclaims.
  • one flank of the disk-shaped dressing tool can have an angle of 15 ° to 25 °, preferably 20 °, while the other flank has an angle of 10 ° to 14 °, preferably 12 °.
  • the head radius can be 0.3 mm to 0.7 mm, preferably 0.5 mm.
  • the disk-shaped dressing tool is reinforced by means of a hard material on its surface.
  • the disc-shaped dressing tool can be occupied according to a further advantageous embodiment of its surface with different grain sizes.
  • a coarse grain on the surface may be selected on the flanks, which may serve, for example, for pre-grinding in a screw profiling.
  • the radius range is occupied by a fine grain.
  • a disc can be profiled, in which case a high-quality surface can be produced on the disc with appropriate profile corrections.
  • the device according to the invention can be used for dressing a grinding worm or a grinding wheel in a conventional CNC rolling and profile grinding machine.
  • a dressable grinding wheel and a dressable grinding worm is used in a conventional manner. Both the grinding wheel and the grinding worm are mounted on a tool mandrel.
  • the grinding worm is used in prototype or small series production of the gears for so-called roughing, whereby a high Zerspan suction and thus a shorter machining time is possible.
  • the grinding wheel applied on the tool mandrel is used for finishing, whereby a good surface quality of the gear prototype is achieved and all profile modifications can be produced.
  • the mandrel grinding worm is first pre-profiled by means of the disc-shaped dressing tool and then profiled finished. Furthermore, also arranged with the grinding worm together on a tool mandrel grinding wheel is profiled with the disc-shaped dressing tool, the profile grinding wheel can be freely and flexibly profiled by the CNC control of the CNC Wälz- and profile grinding machine, whereby a very high profile quality is achieved.
  • sacrificial disk is understood here to mean a tool which serves for rapid and coarse material removal and can be discarded after corresponding pre-profiling.
  • the toothing of the toothed wheel to be produced can now be sanded by means of a combination of rolling and profile grinding.
  • the sole figure shows a disk-shaped dressing tool in an embodiment of a preferred embodiment of the present invention.
  • a disk-shaped dressing tool is shown, which can be installed in a CNC rolling and profile grinding machine (not shown here) and can be driven by it.
  • the disk-shaped dressing tool 10 has two beveled flanks 12 and 14, which converge in a head region 16.
  • the flank 12 which lies on the Anschraubseite of the disk-shaped dressing tool 10, has an angle of 20 °, while the opposite edge has an angle of 12 °.
