Influence of Roughness on Characteristics of Tight Interference Fit of a Shaft and a Hub

Résumé

Tight interference fits are very widely applied in industry, because of their simple manufacturing process. But, in all proposed models for determining their characteristics, one supposes that the contact interfaces are perfect. This is not the case in reality. The objectives of this study are to analyse the contact surfaces behaviour under the effect of the assembly pressure. We show for a given surface texture typology that the roughness has a noticeable influence on the fit strength. Our process uses an experimental approach correlated with numerical modelling of the assembly. The aim is to justify a tightening definition based on the maximum matter concept and to introduce, for this particular case, a prediction of loss due to the deformation of the surface asperities.
