Abstract (en)

[origin: DE19811304A1] The invention relates to a device for determining the lubrication power of fluids, especially fluids used in fluidics/hydrostatics machines and systems, by determining the wear and tear of test parts. According to the invention the fluid is subjected to a pressure, temperature and shear load in at least one sliding contact (between part 8 and part 14) and at least one rolling contact (between part 12 and part 13). The invention is characterized in that the sliding and rolling action is carried out by two test parts each (base part and counter part) independently of each other and the determining mechanical parameters of the tribological stress system, namely normal load of contact and relative speed, can be adjusted independently for each contact.
