Flanders Make is launching a call for interested companies to participate in the User Group of the SBO project Quantified evolution of wear of gears and gearboxes. This project aims to develop technologies for direct, quantitative, automated, visual detection and monitoring of damage on gear flanks.


Detecting and monitoring gear flank damage is extremely important to detect quality problems early, to optimize maintenance costs, and to avoid unexpected gearbox failures.

The existing monitoring methods are based on indirect measurement techniques (e.g. acceleration, noise, rotational speed, etc.). A first problem with the current approach is the lack of validated and robust methods and tools for assessing gear damage. A second problem is that the thresholds for damage detection are based on statistics or on ISO standards (e.g. RMS Overall Amplitude) which are often too conservative and lead to wrong, late, or missed fault detection.

Automated and continuous visual inspection could provide reliable information about the origin and evolution of gear flank damage. This information can be used in the design of better products, in product quality testing, and to improve the accuracy, sensitivity, and predictive power of indirect measurement techniques.

Currently, visual inspection is time consuming because it is not automated and, at the same time, expensive and not robust enough to be used in industrial gearbox monitoring. The proposed SBO project will address these shortcomings.

Expected results of the project

  1. An industrial-grade vision-based inspection tool for image acquisition and automated image processing, for detecting and tracking the evolution of gear flank damage.
  2. Diagnostic indicators based on indirect measurements (such as accelerometers, microphones, acoustic emission sensors and encoders) that outperform the current state-of-the-art in terms of early detection, robust detection and defect size estimation.
  3. Quantitative models that allow rapid calibration of diagnostic indicators for different types of gears under different operating conditions.

How can this project add value to your company?

  • You can propose a short feasibility study that will be worked out in the project.
  • You can also steer the project by providing feedback on the project approach and input based on your concrete interests.
  • You will come into contact with other companies active in the domain.
  • You gain insight into the realization and the project results.

What does such a commitment entail?

As a member of the User Group you participate in consultation moments (2x / year). The project will run for 4 years.

There is a participation contribution of 1000EUR / year for Large companies and 250EUR / year for SMEs.
