Abstract
The FZG test is a usual and standardized method in West Germany to evaluate the antiscuffing properties of oils for reduction gears, hypoid gears, automatic transmission gears, etc. The paper gives a brief survey of the test apparatus, the test gears, and the test procedure. It describes also the criteria of failure and the evaluation of the results, taking into account not only the load-carrying capacity but also the wear performance of an oil. The repeatability and the scattering range is discussed with respect to the test conditions. The field of application for standardized gear rigs is pointed out. This is followed by a discussion of results showing the effect of tooth profile, mineral and synthetic oils, pitch line velocity, temperature, and surface treatment on the load-carrying capacity. Furthermore the paper presents a formula to transfer the obtained test results to other gears. Results of the FZG apparatus are compared with values obtained on Ryder and IAE machines. *Presented as an American So...
