Triboanalysis of hypoid gear components in drive trains

In tribological contact gear systems are heavily loaded and therefore improved surface design and material properties are essential for long life and maintenance-free operation. Thus, mechanisms leading to surface deterioration, lubricant ageing, enhanced friction and morphological changes need to be well understood. In this work a hypoid gear system is analyzed in detail to evaluate critical changes of gear system components after a severe long term test run. Results are the basis to elucidate possible effects due to the tribo-process and to support strategies for system optimization.
