Zusammenfassung
Talking about the design of modern high-performance power train applications, one of the essential components to focus on are the gears. Gears convert torque and speed in a very wide power range, at low cost and with minimal losses and noise emission. However, the demands regarding cost, power density, NVH-behavior and efficiency are steadily increasing. Demands, which can only be met using modern gearing technologies that allow combining individual materials, heat treatment and manufacturing processes. Particularly in the industrial sector, the requirements for the reliability and service life of the gear units have increased. Therefore, more and more accurate calculation methods are required for the load bearing capacity, life expectancy and failure probability as well as better test methods. This aspect is also becoming more important with regard to Industry 4.0 and Predictive Maintenance. In addition, the potentials of innovative production methods like powder metal sintering, plas...
