Abstract

The paper aims to reveal the lubrication bearing mechanism of double-film bearing under different conditions. Modified lubrication models of double-film bearing with laminar/turbulent effect, cavitation and other conditions are established. The function reflection relations between lubrication behavior and structural parameters, working condition parameters are illuminated. The regulations of influences of coupling factors (eccentricity ratio, speed, length-diameter ratio, misaligned angle and operating models) on lubrication characteristics are explored. The lubrication mechanism of double-liquid film interface is elucidated. The variation rules of bearing performance are summarized. The research is important to the optimal design (load-carrying capacity enhancement & friction-reduction) of the double-film bearing.
