Note générale : tribology Langues : Anglais (eng) Mots-clés : redused  Reynolds;  ree-eyring;  spur  gear;  line  contact;  roughness;  mixed  lubrication Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : The unified approach based upon the Reduced Reynolds technique is applied to develop a deterministic transient mixed lubrication line contact model. This model is used in spur gear applications to comprehensively show effects of roughness, working conditions, i.e., rotational speeds and loads on pressure ripples and severity of asperity contacts. Results show effects of the speed, the load, as well as the RMS value are coupled which makes it difficult to evaluate lubrication states by only considering one variable. Considering the Ree-Eyring non-Newtonian behavior could alleviate pressure ripples significantly, compared with the Newtonian fluid assumption. Small RMS values of surfaces, which could be achieved by superfinish techniques, would be desirable when evaluating gear tooth surface contact performances.
