Zusammenfassung
Foreword
Gears bear great responsibility in present times, where the conditions for mechanical engineering and especially for drive technology are changing faster than ever. Megatrends, such as circular economy, decarbonization, green pressure, digitalization, zero waste and several more represent global challenges - but at the same time they are unforeseen opportunities for drives in industry, energy generation and mobility. Gear engineers must find answers to these research questions and provide solutions.
Topics like gear efficiency improvements, performance enhancement of plastic gears, new measurement methods and additive manufacturing are in the focus of the VDI International Conference on Gears 2022 in Garching / Munich. One interesting question is, if we can anticipate break-through innovations to address the challenges above. The opening session of the conference addresses this very question: “What will be the next game-changing innovations and technologies in gear design and production?”.
In the main part of the conference within 40 specialized sessions the latest developments and research results in powertrain industry and academic research are presented and discu...
