Influence of Contamination of Gear Oils in Relation to Time of Operation on Their Lubricity

The quality and reliability of consumables, including gear oils, results in the failure-free operation transmission components heavy trucks. It is known that oil viscosity essential for all lubricated tribopairs wear friction reduction vehicles with a gearbox. Viscosity may be influenced by contamination products can impart on oil. Oil also affect lubrication efficiency boundary conditions gearboxes where slips occur (including bevel hypoid gearboxes). present research focused this issue. An obvious hypothesis was adopted, it theorized exploiting contaminants are how lubricating properties oils deteriorate. Laboratory tests were performed commonly found using Parker Laser CM20. study designed to identify number different solid particles At second stage, conducted couple “ball-on-disc” an bath at 90 °C CSM microtribometer. quantitative contained curves representing coefficients fresh history exploitation compared. test statistically analysed.
