Definitions
- the toothed component for example a toothed wheel
- the material removal of the edge zone roughly corresponding to the area of the edge decarburization.
- a grinding method is preferably provided as the machining method, which has been provided in practice to improve the surface quality of the tooth flanks.
- the area of the tooth base is usually not subsequently processed. This means that the cost-intensive shot peening known from the prior art can be avoided, and therefore no additional costs for shot peening are incurred in comparison with conventional production methods.
- the course 2 of the carbon content is set in the entire edge region of the gearwheel using the case-hardening method described above.
