Definitions

  • this invention relates to a profile tool for cutting work pieces in the form of spiral and hypoid bevel gears, specially for transmission of motor vehicles.
  • the CNC dresser can have here a rotating dressing tool in the form of a diamond molding roller.
  • the perpendicular position of the rotational axis of the diamond molding roller is determined by the working range.
  • the dresser spindle is situated upon a cross slide movable in two CNC axes.
  • the diamond molding roller is guided along the grinding wheel outline, there being taken into account its geometric defining quantities, that is, the profile radius and the diameter.
  • diamond molding rollers have a substantially greater stability of the profile radius so it is possible exactly to also dress grinding wheel outlines having large profile angular area. They are thus suitable both for partial roller grinding and for profile grinding.
  • the profile coordinates of grinding wheels that is, the nominal outline, is calculated here with a special software on the basis of work piece data taking into account the specific conditions of the partial wheel grinding or of the profile grinding.
  • the calculated grinding wheel profiles are mathematically describable basic shapes, specifically straight edges for the partial roller grinding and involutes for the profile cutting.
  • the best known CNC controls can directly process only straight edges, arcs or splines. If for the above described reasons, modifications are overlaid on the basic shapes, then these must be described generally by tables of interpretation points in view of the complex calculation.
  • the problem of this invention taking into consideration the increasing demands on the functionality of bevel gear sets, is especially the noise level, the load capacity and the relocation capacity, the same as with regard to an easy assemblage and economic production to propose a profile tool with which the possibilities of design in the development of bevel drives are improved and special profiles are made possible.
  • the invention provides that the profile of a profile tool for cutting spiral and hypoid bevel gears, which profile is exclusively defined by the use of straight edges and circles and combinations thereof, is modified by overlaying in radial direction a nth order polynomial.
  • the profiles of said sections result then from the radial overlaying of the conventional profile elements, that is, straight edge and/or circle with the new profile element, that is the nth order polynomial.
  • the origin of the coordinates can be freely selected for each polynomial used and in the simplest case is in the transition from one section to the other.
  • the generation of the tool profile shape by the machine kinematics is prior art. This can be done on the production machine and also on a special machine for tool production or tool reprocessing. By adequate development and adaptation of the software, the inventive profiles can be generated on the tool.
  • FIG. 1 shows a radial section through such a tool
  • FIG. 2 shows an enlarged representation of one part of the tool.
  • FIG. 1 a radial cut through an inventively designed profile tool adequate for cutting spiral and hypoid bevel gears such as for the bevel drive of a motor vehicle.
  • the origin of the coordinates for each polynomial used can be freely selected and in the simplest case lies in the transition from one section to the adjoining section.
  • the individual polynomial can here be defined, as shown in FIG. 2, as follows:
  • ⁇ — rp K 2 * ⁇ — xp 2 +K 3 * ⁇ — xp 3 +. . . K i * ⁇ — xp i +. . . +K n * ⁇ — xp n
  • Ki coefficients are real numbers which, as needed, can be freely selected for each section and in the special case can also assume the value 0.
  • profile forms defined by dot sequences or splines when they can be approximated as combination of the above described profile elements (straight edge, circle and polynomial) in the effective area, that is, of the formation of the cutting on the work piece with a maximum radial divergence of 0.003 mm and when the most favorable approximation by straight edge and circle is more inaccurate.
