Abstract

Aiming at the influence of journal inclination Angle on water-lubricated bearings, a mechanical model of propulsion shafting bearing load was established by theoretical analysis and numerical simulation to analyze the bearing force. Then a water lubricated bearing model is constructed, and the distribution characteristics and rules of water film pressure are obtained by simulating the inclined water lubricated stern bearing. The change of vertical inclination Angle has no effect on the water film pressure distribution. At low speed, the change of inclination Angle has little influence on the water film pressure, while at high speed, the influence on the water film pressure is obvious. When the pressure reaches the peak, the water film breaks, which makes the bearing contact stress value more concentrated.
