MTS 05 Gear Failures and Tribology of Gears

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


To have notions of metallurgy, mechanics and kinematics of the gears.


Teaching method alternating theory and practice through case studies or works directed.


Engineers and technicians of Design Offices, production and measurement departments.
