Surface Roughness Parameters Evaluation in Rolling/Sliding Wear TestsS
MetadataShow full item record
Rolling/sliding wear tests were performed on an Amsler test rig. Normal load (expressed as the Hertzian pressure) and the roll-slide ratio have been considered to have the most important influence in simulating gear functioning on two-rollers machines. The surface topography changes are studied using a comparison between unrun and worn digital profiles, some statistical parameters variation and the bearing area curves analysis.
