Christoph Lohmann studied mechanical engineering at the University of Applied Sciences of the Lower Rhine in Krefeld and at the Ruhr University Bochum, graduating as a cooperative engineer-in-training at Bayer AG. He concluded his studies in 2012 with his masterâ€™s thesis â€” â€śSimulation of System Dynamics of Heavy Drivetrains with Multi-Body Simulationâ€ťâ€” at SEW-Eurodrive GmbH & Co KG in Bruchsal. In 2012 he started as a research assistant at the Chair of Industrial and Automotive Drivetrains of Prof. P. Tenberge. Lohmannâ€™s fields of research are tooth contact analysis, tooth profile modifications, fatigue failure and tribological stresses.

- Optimal Modifications on Helical Gears for Good Load Distribution and Minimal Wear (June 2015)
Helical gear teeth are affected by cratering wear â€” particularly in the regions of low oil film thicknesses, high flank pressures and high sliding speeds. The greatest wear occurs on the pinion â€” in the area of negative specific sliding. Here the tooth tip radius of the driven gear makes contact with the flank of the driving gear with maximum sliding speed and pressure.
