A modified FZG-Ryder gear machine was developed to run |
|
scuffing tests at high speed (n1 = 9700/min) 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. |
