May 20, 2015—
The flank fracture calculation according to ISO/DTR 19042 was recently added to the latest KISSsoft release 03/2015 (module ZZ4). This type of damage manifests itself as crack formation at greater material depths. It can occur on both cylindrical gears and bevel gears. In the majority of cases, flank fracture causes the gear unit to fail completely.

The ISO Committee is currently working on the ISO/DTR 19042 calculation standard for cylindrical gears. This standard includes a method for performing the calculation with simplified load assumptions (Method B) and a local process, which makes it possible to analyze the risk of damage across the entire meshing (Method A). In the new KISSsoft Release 03/2015, both methods are available to users.
