Prof. I.R. Dr.-Ing. Wolfgang Predki
Until his retirement in 2012, Prof. Dr.-Ing. Wolfgang Predki served with distinction as Head of Chair for Mechanical Components, Industrial- and Automotive Power Transmission (LMGK) at Ruhr-University Bochum since 1992.Upon receiving his doctorate in 1982, Predki began work at the former Flender AG. His last position was as Head of Engineering, where he was responsible for worm, standard- helical, and planetary gears. In his 20 years as a professor Predki supervised many dissertations, published countless reports, and headed the DIN and FVA working groups for worm gears (Bio last updated 2014-09-01 Contact Randy Stott, Managing Editor, with changes.)

- Micropitting of Large Gearboxes: Influence of Geometry and Operating Conditions (September/October 2014)
The focus of the following presentation is two-fold: 1) on tests of new geometric variants; and 2) on to-date, non-investigated operating (environmental) conditions. By variation of non-investigated eometric parameters and operation conditions the understanding of micropitting formation is improved. Thereby it is essential to ensure existent calculation methods and match them to results of the comparison between large gearbox tests and standard gearbox test runs to allow a safe forecast of wear due to micropitting in the future.
