EHL formulas; line contact; film thickness; asperity load ratio; surface roughness
Three formulas are derived for predicting the central and the minimum film thickness as well as the asperity load ratio in line-contact EHL with provision for surface roughness. These expressions are based on the simultaneous solution to the modified Reynolds equation and surface deformation with consideration of elastic, plastic and elasto-plastic deformation of the surface asperities. The formulas cover a wide range of input and they are of the form f(W, U, G, (sigma) over bar, V), where the parameters represented are dimensionless load, speed, material, surface roughness and hardness, respectively.
