Friction reduction in EHL contacts by surface microtexturing – tribological performance, manufacturing and tailored design

Stephan Tremmel, Max Marian, Michael Zahner, Sandro Wartzack, Marion Merklein

This paper aims to derive tailor-made microtextures for elastohydrodynamically lubricated (EHL) contacts under consideration of manufacturing possibilities.

Influence of the grinding process on the tribological behavior of gear analogy test parts

Christian Brecher, Christoph Löpenhaus, René Greschert

Boundary layers, which develop during manufacturing and operation, can protect tooth flanks from metal-to-metal contacts. The characteristics of boundary layers and the running…

Power loss reduction in timing chain drives by adjusted tensioning and surface structuring

Bernd Sauer, Frederik Krupp, Andre Becker

Energy losses in a timing chain drives are caused by friction in chain-rail contacts. To improve the efficiency, the Chair of Machine Elements and Transmission Technology at the…

Enhancement of roller bearing fatigue life by innovative production processes

Florian Pape, Oliver Maiss, Berend Denkena, Gerhard Poll

The efficient and economical use of natural resources is a big issue. Machine elements with a rolling contact are highly relevant because of their wide application in technical…

Multi-scale surface patterning – an approach to control friction and lubricant migration in lubricated systems

Philipp G. Grützmacher, Andreas Rosenkranz, Adam Szurdak, Markus Grüber, Carsten Gachot, Gerhard Hirt, Frank Mücklich

The paper aims to investigate the possibilities to control friction in lubricated systems by surface patterning, making use of a multi-scale approach. Surface patterns inside the…

Influence of tribofilms on failures and friction of gears with particular focus on running-in

Andreas Ziegltrum, Stefan Emrich, Thomas Lohner, Klaus Michaelis, Alexander Brodyanski, Rolf Merz, Michael Kopnarski, Bernd-Robert Hoehn, Karsten Stahl

This paper aims to address the influence of tribofilms and running-in on failures and friction of gears. The operation regime of gears is increasingly shifted to mixed and…
