Aachen Forum on Gear Production – Gears for Electromobility. 9th – 10th November 2023 [PDF ebook] 

Dukung

Gears have served as indispensable components across a spectrum of sectors, including automotive, aerospace, industrial applications or wind turbines, for many decades. However, increasing requirements and current market developments are constantly presenting the transmission technology industry with new challenges. In modern gear transmissions, competition extends beyond pricing and hinges on factors such as load-carrying capacity, operational reliability, and noise reduction performance. Modern transmission have to achieve high power density, low weight and minimal noise emissions. The current trend towards e-mobility, coupled with general ecological and economical challenges to improve resource efficiency, lead to increased demands on the entire process chain in gear production.
At this year’s Aachen Forum on Gear Production (AFGP), hosted by RWTH Aachen University’s WZL in collaboration with the Research Association for Drive Technology (FVA), the central theme will revolve around the manufacturing of gears for use in e-mobility applications.
The spectrum of topics ranges from process and tool design in line with requirements to the manufacturing of individual gear geometries and measures for continuous quality assurance. Additionally, the event will delve into areas related to digitalization and the advancement of sustainability in both gear production and its application.
