| Abstract: | The paper deals with experimental mechanics in the field of fluid lubricants, investigating frictional characteristics of automotive engine and gear oils using experimental tests on a pin and vee block test machine (Falex). The test is standardized according to ASTM D3233 and represents a relevant and rapid measurement of coefficients of friction in a tribometer. Three engine oils and three gear oils were tested on the same loading-time procedure being analyzed the coefficients of friction according to SAE class of viscosity, degree of use ( fresh or aged) and manufacturer. The calculations at different speeds and loads proved that coefficients of friction comply with the Stribeck rule. The research work succeeded to set up a procedure for operation on Falex machine, both for research and educational purposes. |
