摘 要: | 以38 000 DWT杂货船推进轴系为研究对象,比较分析艉管有前、后轴承和艉管仅有后轴承两种轴系布置方案下各轴承负荷、垂直位移等变化,特别是SMCR工况下轴承负荷的分布情况。结果表明:仅有后轴承,并将中间轴承后移,能够更好地改善轴系运行状态。

Abstract: | The 38 000 DWT bulk carrier propulsion shafting was taken as the research objection .For the two kinds of ar-rangement of the propulsion shafting system , one has fore and after stern tube bearing and the other only has after stern tube bear -ing, the bearing load and vertical displacement of bearing were compared , especially the bearing load distribution when main en-gine running at SMCR .The results showed that cancelling the fore stern tube bearing , and shift the intermediate bearing aft , it can improve the system running condition . |

Keywords: | shafting alignment bearing load fore stern-tube bearing |
