Gear Wear & Damage Recognition - Introduction to the new ISO 10825

Course Provider

Centre for Professional and Continuing Education (PaCE@NTU)


Continuing Education and Training Certificate


A vision into the appearance and fundamental causes of gear failure modes. This training provides gear manufacturers and users with the necessary skills to examine, assess and recognize common gear failure modes.


Cetim, the leading French Technical Centre for Mechanical Industry, was established in 1965 to support innovation and competitiveness of engineering companies through its multidisciplinary expertise and unique R&D capabilities.

In Asia Pacific, CETIM-Matcor, a forward-looking company, is specialized in the field of Material & Corrosion Assessment, Failure Analysis & Forensic Investigation and Mechanical Power Transmission.

Jointly with NTU, CETIM-Matcor will conduct advanced engineering courses for engineers who will like to understand and learn in depth knowledge from our experience trainers with vast industrial and field experience. Courses are largely focused on Corrosion Engineering and Failures Analysis in areas such as Pressurized Equipment, Shafts, Gears & Bearings as well as Forensic Engineering Investigation.

The training provides participants with:

  • Examine the different aspects of gear failures.
  • Assess and interpret common gear failure modes.
  • Appreciate what is considered normal wear and what could potentially be a problem and know the appropriate action to take.
  • ISO Standards
    • Key principles in ISO Standards
    • Members (how to get involved), Technical Committees and Working Groups
    • The different type of ISO publications
  • Basic concepts on the geometry of gears to "Teeth in involute"
    • Spur and helical gears
    • Meshing (contact ratio, interference, sliding)
    • Tooth modifications (profile and helix)
    • Contact pressure and tooth rupture calculations
  • Gear failure analysis method and failure recognition strategy.
    • Introduction to the common investigation methods and equipment used
    • Introduction to the new ISO 10825
    • Classification of failure modes in gears
      • Tribological damages (non-fatigue)
      • Fatigue damages
      • Non-fatigue fracture
      • Plastic deformation
      • Manufacturing issues
      • Other surface damage
  • Case studies (a chance to test your failure recognition skills).
  • Questions / answers.

The course is designed for various disciplines that includes plastic gear designers, gear service personnel, operators and users of valuable equipment, inspection and certification bodies who need to confidently examine gears and gearboxes and those new to the gear industry.

Applicants should possess a Diploma or Degree with Engineering.
