A study of grease film thicknesses in elastorheodynamic rolling point contacts

Abstract An elastorheodynamic analysis and a numercial solution are presented for grease film thicknesses in rolling point contacts for fully flooded, isothermal and steady state conditions. The contact surfaces are smooth and a grease four‐parameter rheological model is considered. A modified Reynolds equation is established and a complete numerical solution, including surface deformations, piezoviscous, and compressional effects is given.
