Meshing interference

It is materialized by the appearance of small scratches and broken away on a tooth head line or tooth bottom. In some cases, by damage like pitting or chipping in tooth root for the gears. Several sources are possible:

  • Profile machining defect in the case of new gear
  • Replacing a worn gear with a new one without action on the girth gear
  • Setting default (bottom tooth too high, for example)

The interference often causes a vibratory increase.
