摘要:
 船舶机械设备在长期的运转使用中, 由于多种因素, 其技术状态和使用性能会不断下降。以某轮主机增

压器转子轴断裂为实例, 对增压器进行解体后, 发现转子轴从压气叶轮端布司轴颈处断成两段, 推力轴

承、浮动轴承均有不同程度的损伤, 增压器压气端叶轮与壳体之间有明显的擦碰痕迹。经判断, 该断裂

属于典型的弯曲—扭转疲劳破坏。鉴于此, 要求轮机管理人员和船舶管理公司均要不断提高管理水平,

综合运用各项知识与技能, 确保船机设备及船舶的安全运营。

Abstract:
 Due to internal and external factors, the technical and operational performance of ship’s

machines and equipment will decline increasingly in the process of long-term operation.

Taking the fracture of a main engine turbocharger rotor shaft as an example, after the

turbocharger dismantled, it is found that the rotor breaks into two parts at the neck of

compressor impeller shaft; thrust bearings and floating bearings are damaged to varying

degrees; there exist obvious rubbing marks between the impeller and the shell of the

compressor impeller. It is concluded that the fracture is a case of the typical bending-

torsional fatigue failure. In view of this, the marine engine management personnel and ship

management companies are required to improve their management competence consecutively and

apply their knowledge and skills comprehensively so as to ensure the safe operation of

ship’s mechanical equipment and ships.
