Lab-scale testing and performance screening of gear oils

Kurzfassung

In this study several commercially available lubricants, differing in viscosity levels, were investigated in terms of scuffing and friction behavior as well as wear resistance. The recently published Gear Performance Screening (GPS) was combined with reciprocating wear tests on a SRV tribometer. The proposed test method facilitates a time and cost-efficient screening of state-of-the-art and next-generation gear oils, the latter oftentimes exhibiting low HTHS-levels and advanced dielectric properties. This method has the potential to bridge the gap between lab-scale testing and full-scale component validation.
