Definitions

  • the invention relates to a method for scraping gearwheels, in which the flanks of the teeth of an unhardened toothed work wheel are machined with a rotary-driven scraping tool, the axes of the work wheel and the scraping tool being at an axis cross angle to one another, so that at least one chip edge of the scraping tool coexists The pressure and feed roll along the gear wheel flank.
  • the invention further relates to a device for carrying out the method.
  • the shaving wheel rolls under flank pressure with the work wheel like a helical-roller gear with crossed axes.
  • this is a gearwheel with high toothing accuracy, in the tooth flanks of which several cutting grooves extending from the tooth head to the tooth base are incorporated alongside one another over the entire width.
  • the shaving wheels have to be adapted to the dimensions and toothing data of the work wheel from case to case.
  • the exact desired topography of the gearwheel is determined by complex tests and repetition of the work steps such as trial scraping, hardening, correction of scrapers, trial scraping, hardening, etc. until the desired toothing is achieved after hardening. This is technically complex and therefore expensive.

  • the invention has for its object to provide a method for scraping gears and an apparatus for performing the method. fen, whereby gears can be scraped inexpensively while maintaining an exact topography of the tooth flanks.
  • the method according to the invention makes it possible to carry out the scraping machining of the gear wheel tooth flanks by means of at least one single tooth.
  • the chip edge of the single tooth moves on a cycloid so that each tooth flank can be swept by the chip edge of the single tooth by rolling. Due to the scraping with pressure and feed along the gear wheel tooth flank, there is a reversal of rotation of the gear wheel and single tooth, so that first the one tooth flank and then the opposite tooth flank can be machined. Due to the reduction of the teeth of a gear wheel known per se to a single tooth, the topography of the gear wheel flank on the work wheel can be generated by programmable and thus correctable machine axes. The result is exact tooth flank machining on the work wheel.
  • the at least one chip edge of the single tooth can be ground using optimal cutting geometry.
  • the gear kinematics are the same as for the scraper wheel according to the prior art. This means that the scraping tool and work wheel axes intersect and form the axis cross angle. This results in a relative speed of the chip edge in the direction of the flank line, and a chip is formed due to the penetration of the chip edge and the gear wheel tooth flank.
  • the amount of the pressure is set by a torque control.
  • the removal of chips over the entire width of the work wheel is achieved by the fact that the scraping tool (single tooth) and the work wheel are clamped together radially with little force and simultaneously roll on one another.
  • the scraping tool and the work wheel are driven and electronically coupled.
  • the radial clamping force can be superimposed by an interpolation of the X and Z axes, which means that each tooth flank can be generated individually with a calculable topography.
  • This means that the flank shape of the gear wheel tooth flanks is influenced by a variation in the torques.
  • the speed of the at least one single tooth made of hard metal is greater than 200 rpm.
  • the method according to the invention is characterized by dry machining of the work wheel by the at least one individual tooth. Wet cooling is therefore not necessary.
  • the device for scraping gearwheels is characterized in that the at least one chip edge is formed by at least one individual tooth.

  • the at least one individual tooth can be coated. There are therefore all the possibilities of coating technology combined with optimum cutting performance. With regard to optimal machining, the negative rake angle proves to be favorable.
