Description
Summary:The paper presents the rheological behavior of a MP multifunctional grease (additived, for EP, containing Li and Ca soaps- for general use), experimentally obtained on the THERMO-HAAKE Viscotester VT550, as τ(γ) correlations, at different temperatures, between 15-60°C. It results a strong non-Newtonian behavior, with threshold, time depending (tixotropy or rheopexy, depending on the operating conditions). With the aid of the rheological parameters, obtained from the experiments, it is analyzed the influence on a ball bearing frictional coefficient μ in the contact zone ball-inner ring, in the case of the elasto-hydrodynamic-lubrication (EHL).
