Classroom Training


Test Course Only

Understand gear failures and tribology of gears to avoid disruptions to operations. Implement appropriate corrective actions using a structured failure analysis approach.


Upon completion of the training, the attendants will be able to carry out the following:

  • Understand the tribological aspects of in-service gear drives
  • Explain the mechanisms of damage and identify the causes of the failures
  • Propose appropriate corrective actions
  • To exchange with experts in the field
