What are the mechanisms of friction that occur in the highly pressurized contacts between mating gear teeth, and how are these changed with for instance sliding speed, temperature and oil type? These are typical questions to be answered in this research projects which aims to provide knowledge to the Swedish automotive industry for more efficient drive trains leading to reduced fuel consumption, emissions and increased service life.

Friction and wear can not be predicted with high accuracy and reliability and it is, therefore, not possible to predict and optimize energy efficiency, fuel consumption and service life. Such prediction and optimization are very important for the development of sustainable mechanical components and systems with excellent environmental performance.
A simulation model and tool for efficiency and life optimization will be developed. The effect of surface finishing method, hydraulic fluid, operating conditions, component geometry, and material properties on efficiency, leakage, and service life should be possible to predict by using the tool.
A model describing the onset of scuffing will be developed. This is a model describing the influence of parameters such as contact pressure, flash temperature, roughness, lubricant, material properties on the risk of local scuffing or complete seizure
