Effect of Deformation of Propeller Shaft on Performance of Sterntube Bearing

Abstract

In order to prevent the damage of sterntube bearing due to misalignment, it is necessary to clarify the dynamic behavior of propeller shafting system. The shaft is bent by heavy propeller, action of dynamical propeller force and deformation of double bottom, and affects consequentially the sterntube bearing. This paper presents a theoretical analysis of sterntube bearing under a misaligned shaft. The relation between misalignment condition and performance of sterntube bearing has been investigated quantitatively.
