Original abstract

This study investigates the effect of different lubricant entrainment velocity angles on film thickness distribution. For this purpose, a steady-state isothermal EHL model is used under a wide range of parameter sets including varying sum velocity, contact pressure, and sum velocity angle. The results are compared with experimental measurements by means of an optical ball-on-disc tribometer and a twin-disc machine using capacitance method.

Czech abstract

Tento článek je zaměřen na vliv směru unášivé rychlosti na elastohydrodynamický mazací film. Byl použit iozotermální EHD model za ustálených podmínek v širokém rozsahu vstupních parametrů zahrnujících unášivou rychlost, kontaktní tlak a úhle unášivé rychlosti. Výsledky byly porovnány s experimentálními měřeními pomocí optického tribometru typu ball-on-disk a dvoudiskového stroje s kapacitantní metodou.
