In order to achieve energy savings, ships are now being designed with larger propellers operating at lower speed. Such designs impose a heavier load on the stern tube bearing. The shaft alignment calculations have been made taking oil film characteristics of stern tube bearing into consideration. The oil film characteristics have been analyzed by the finite width hydrodynamic theory applying to the curved shaft in the stern tube bearing.
This theoretical analysis has made it possible to elucidate the oil film characteristics of the stern tube bearing. The optimum width-diameter ratio of the stern tube bearing at lower speed has been also obtained by this analysis.
