The standard is fundamental to gear manufacturing because it standardizes the shape of the cutting tools (hobs and shaper cutters). If a gear is designed according to DIN 867, it ensures interchangeability and compatibility with mating gears and standard tooling.
It defines the of involute cylindrical gears. In simpler terms, it sets the mathematical and geometric rules for the "master tooth shape" from which gear cutting tools (like hobs or rack cutters) are derived. din 867 pdf
DIN 867 is largely consistent with the international standard ISO 53 , though it includes specific amendments regarding profile corrections and crest clearances. Key Technical Specifications The standard is fundamental to gear manufacturing because
