Dr.-Ing. Matthias Walkowiak
Dr.-Ing. Matthias Walkowiak has since 2013 worked as a calculation and development engineer at SEW-Eurodrive GmbH & Co KG in Bruchsal. Upon receipt of his engineering degree he began his career at the chair of Machine Elements, Gears and Motor Vehicles of Prof. W. Predki at the Ruhr University Bochum as a research assistant. He completed his PhD successfully in 2013 with the doctoral thesis, â€śLocal Loads and Wear Simulation of Tooth Meshing on Spur and Helical Gears with Profile Modifications Between the Beginning and the Ending of the Deflection,â€ť at the chair of Industrial and Automotive Drivetrains of Prof. P. Tenberge. (Bio last updated 2015-06-01 Contact Randy Stott, Managing Editor, with changes.)

- 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.
