Classroom Training

Failure Analysis of Shafts, Gears and Bearings

Understand the causes of failures of power transmission components (shaft, gears and bearings) to better avoid them. Implement appropriate corrective actions using a structured failure analysis approach

Objectives:

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

  • Identify the different aspects of the incriminated parts and the causes of the failures
  • Interpret the damage in areas affected by equipment failure
  • Implement the damage analysis and the appropriate corrective actions
  • To exchange with experts in the field

Date:

9th – 11th November 2021 (Tuesday to Thursday)

Time:

09:00–17:00 (GMT+8)

PRE - REQUISITES​​

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