For years, the intemational gear manufacturing industry has been pushing machine manufacturers to develop an
economical realizable tooth flank modification that is made in contact direction, with a soft transfer from the modified to
unmodified sections of the tooth.
To meet these demands, H6fler has developed, and is already implementing, Generated Eogagement Relief
Modifications. The tooth flank is modified at the areas of engagement only as opposed to the entire tooth flank as is the
case with conventional modifications. The paper will discuss the advantages of this new technology over conventional
modifications and discuss how to produce generated engagement relief modifications.
