The impact of seawater corrosion on friction torque of bearing deputy campaign

摘要

According to the stress state and corrosion resistance of bearing deputy campaigns,NO.5 bearing deputy campaign was selected as research subject.The work including design,processing,finite element load calculation,friction torque before and after corrosion of bearing deputy campaign samples were carried out according to similarity theory.Friction torque calculations of bearing deputy campaign before and after corrosion were 2.9×106N·mm and 3.2×106N·mm respectively.Compared with the friction torque before corrosion,the friction torque of bearing deputy campaign was increased by 10.4％ because of seawater corrosion.
