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, “Local Loads and Wear Simulation of Tooth Meshing on Spur and Helical Gears with Profile Modifications Between the Beginning and the Ending of the Deflection,” 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 — particularly in the regions of low oil film thicknesses, high flank pressures and high sliding speeds. The greatest wear occurs on the pinion — 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.
