In view of the friction and wear caused by inclination of the stern bearing journal under load
the elastohydrodynamic lubrication models of the circular and grooved water lubricated rubber bearings with the journal center of the split plane as the base point are established. The pressure and film thickness distributions of the water lubricated rubber bearing in journal alignment and misalignment states are solved by finite difference method. The influences of journal inclination angle on the static performances of the bearing such as oil film force
oil film moment and pressure center are discussed. The results show that the static characteristics of the circular and grooved bearings change obviously after journal tilting. The maximum oil film pressure increases rapidly when the inclination angle increases beyond a certain threshold. Meanwhile
the minimum oil film thickness decreases to the allowable minimum thickness with the increase of the inclination angle of the journal. Besides
