PECULIARITIES OF THE ELASTOHYDRODYNAMIC LUBRICATION OF CROWNED ROLLER

Abstract cze:
Abstrakt: Method and results of numerical simulation of the elastohydrodynamic (EHD) lubrication of the profiled roller of finite length are presented. Peculiarities of the influence of crowning geometry on pressure and film thickness distributions in the EHD contact are shown. In particular, it is shown that the film thickness at the centre of contact is near-constant value but the minimum film thickness decreases appreciably when the parameter of crowning increases, other conditions being equal.
