The Influence of Anti-Wear Additives on the Bearings Hydro-Mechanical Characteristics

The experimental dependencies of the friction coefficient and the wear rate for lubricants without additives and the oil containing an anti-wear additive are obtained. The received laws cannot be explained with the hydrodynamic theory of greasing, theories of boundary friction or their combination. To eliminate these contradictions we offer a rheological model of a lubricant including the dependence of viscosity on a thickness of the lubricant layer.
