Gearboxes are used to adjust the rotational speed and torque of drive and output devices, with gears as the central machine elements. They should perform their duties in a low-noise, low-maintenance, and most of all damage-free manner over the lifetime of the machine. Breakdowns due to damage often lead to high costs.

Target Audience

Employees of gearbox companies and technical departments: designers, production engineers, maintenance and repair specialists, and experts.

Main Topics

  • Gear damage
  • Influencing factors
  • Testing procedures
  • Calculation methods
  • Avoidance
  • Examples


  • Reliable detection and classification of gear damage
  • Information on the main damage influencing factors
  • Calculation approaches for quantitative assessment of damage risks
  • Systematic approach to failure analysis
  • Quantitative and qualitative assessment of ways to prevent damage


  • Foundations of gear stress and failure analysis procedures (modified root cause analysis)
  • Seizure, wear, micro-pitting, fissures, tooth root and flank fracture of spur gears
  • Appearance and causes of damage, primary influencing factors, testing methods, calculation principles, and practical examples
  • Fundamentals of materials and lubricants
