3. Conclusion

The articles to follow a product-oriented approach to analysis, study and presentation, in this case of timing belts. The presentation of the context of use and technologies, as well as knowledge of the performance objectives, have made it possible to clearly specify the challenges and possibilities of these transmissions. In addition, a classification of the influencing parameters, taking into account the objectives, made it possible to select suitable models. For example, it was necessary to define in detail the geometrical aspects of meshing and the characteristics of the materials involved. Similarly, a numerical calculation tool was developed to take into account both the global aspect of power transmission and the local aspect of transmission of forces between teeth. The implementation of a numerical model simulation tool adapted to the problem...
