Abstract:

A modified FZG-Ryder gear machine was developed to run scuffing tests at high speed n1 9700min and oil temperatures from 74 C to 200 C. Test oil volume is approximately 3 liters. Good correlation was found between FZG-Ryder and standard Ryder test results when rating ester base lubricants and using ester base reference oils such as Hercolube A . Poor correlation was found when using mineral based reference oil C . Tests on three oils at 200 C showed considerable lower load capacity as compared to ratings at 74 C. However, relative ranking of the lubricant was unchanged. Keywords Load capacity, Lubricant, Test methods.
