  • DE 195 17 385 C1 and DE 195 17 359 C1 have disclosed processes for finishing the hardened toothing of a bevel wheel by honing. Honing is done after grinding the bevel gear by grinding on the same machine.
  • the honing tool preferably consists entirely of corundum or at least has abrasive flanks.
  • the object of the invention is first achieved by the features of claim 1. According to the honing is provided for the finishing of the veloid gears. This achieves the advantages of high surface quality and noise reduction.
  • the apparatus for carrying out the method has a conical honing tool, which is used for fine and final machining of a beveled gear with beveloid toothing.
  • Beveloid toothing is understood to mean a conical spur gear toothing, as defined in particular in the aforementioned prior art (in "Gear Technology”) .
  • the tool according to the invention is preferably designed as a honing ring with a conical internal toothing, but can also be designed as a bevel gear with conical External teeth are formed Honing tool has an abrasive surface by means of which material is removed from the work gear to improve the surface quality.
  • the axes of rotation of the workwheel and the honing ring have a fabrication axis distance which corresponds to the axis slot.
  • the axis of rotation of the honing ring is inclined about the Achsnchwinkel K relative to the axis of rotation of the work wheel, d. H. the honing ring is pivoted about its y-axis.
  • the conical internal toothing engages in the pre-toothed work gear.
  • the teeth of the honing tool and the head of the toothing can be dressed with a diamond-coated dressing wheel or a conical dresser.
  • Fig. 2 the honing ring with work gear, seen in the Y direction and Fig. 3 shows the profile of a molding tool.
  • Fig. 1 shows a honing tool 1, which is formed as a conical ring, and a work gear 2, which is formed as a pinion with a conical spur gear toothing, a so-called beveloid toothing 3.
  • the honing ring 1 has a conical internal toothing 4, which engages in the conical outer toothing 3 of the work wheel 2.
  • the inner toothing 4 of the honing ring 2 has - which is not shown - an abrasive surface, which is achieved by a corresponding hard material coating of the toothing can or in that the entire honing ring made of an abrasive material, for. As corundum is produced.
  • the conical internal toothing 4 is bounded by a cone 5, a so-called head cone.
  • the honing ring 1 and the workwheel 2 each have axes of rotation Z 0 , Z 1 , which are offset from one another by a manufacturing axis distance a - measured on the Y-axis.

  • no additional tilting about the X-axis is required to achieve the taper, which allows the application on conventional honing machines.
  • the XZ planes of gear 2 and honing ring 1 can be parallel (as shown). Deviating from this, arrangements with an additional tilting about the X-axis can also be used, whereby a lower conicity of the honing ring 1 can be achieved.
  • a diamond-coated dressing wheel (not shown) may be used, which represents the desired geometry of the work wheel 2. With this dressing the tooth gaps of the internal teeth 4 are processed in the honing ring 1.
  • an unillustrated conical dresser for the head cone 5 of the honing ring 1 is required. Since the head angle remains constant over the entire dressing process, the dressing of the head cone 5 can be coupled directly to the dressing of the tooth gaps of the internal teeth 4 of the honing ring 1.
  • dressing can be carried out by changing the axial distance a between honing ring 1 and dressing wheel without having to correct the position of the head dresser.
  • the honing ring 1 can be pre-toothed with a mold, not shown, which produces a tapered profile.
  • the shape of the gap profiles changes only slightly on the honing ring 1 due to the larger number of teeth over the tooth width, so that made with a mold gap makes only a small removal in the first dressing required.
  • Fig. 3 shows an example of the profile of a molding tool, not shown, for the pre-teeth of the honing ring 1 and over the tooth width existing gap shapes.
  • a profile disk 6 is represented by a solid line and has a V-shaped profile which engages in the tooth spaces of the honing ring 1.
  • the gap shapes are represented by three differently marked polylines for three positions of the tooth width: the gap shape for an inner position is diamonds, the gap shape for a middle position is squares, and the gap shape for an outer position is triangles.
  • the tool as bevel gear with Beveloid external teeth and the work wheel as a conical ring with Beveloid internal toothing.
  • the inventive method for honing Beveloid gears is applicable for both internal and external tapered gears.
