Master’s thesis: Thermal Films – The Future of Bearing Performance – An Alternative to Traditional Run-in Processes

The Institute of Machine Elements and System Engineering researches the fundamental structural and tribological behaviour of machine elements and represents them in experimentally validated model descriptions. These model descriptions are used to analyse and design the functional, loss and noise behaviour of entire technical systems with a focus on drive technology. The developed models are also used to research and develop methods of Model Based Systems Engineering as a central element of future inductive product development processes.

Rolling contacts, such as those found in bearings, gears, and other machine elements are integral components of numerous mechanical systems. The efficient operation and longevity of these systems depend on the intricate interplay between the contacting surfaces and the lubricant. One critical aspect that significantly influences the performance of such contacts is the formation and behaviour of boundary layers. These thin films, which develop at the interface between the contacting surfaces, play a pivotal role in minimising wear and enhancing the overall efficiency and durability of the systems. Normally, these protective films are formed during the run-in period of bearings under moderate conditions, which is costly and time-consuming. This thesis offers an exciting opportunity to study the formation of these films without a need for separate run-in procedures.
