EXPERIENCES OF STUDYING GEAR TRIBOLOGY IN A FZG TEST SET-UP

• The main objective of this study is to review the last decade of experimental work in the field of gear pitting life andefficiency of an FZG gear test rig. Located at KTH Machine Design, the FZG rig has led to critical findings with an impacton gear transmissions, such as high efficiency and long fatigue life. The different FZG test set-ups, the sampling methodsand the results (and their limitations) are discussed, and measures are proposed to reduce the limitations. The findingsof this study are used as input to an impact case on how research at a university can provide the major transportindustry in Sweden with the knowledge and the methods to evaluate gear performance.
