摘要
针对某DWT45000型油轮在南海海域发生的中间轴断裂事故,通过对中间轴断裂成因的系统检测与力学分析,揭示了轴系中线偏差的关键致因。采用三维激光测量技术对主机–轴系轴线进行精密校准,提出基于环氧树脂浇注工艺的主机基座整体沉降修复方案。修复后主机拐档差由0.51 mm降至0.15 mm,轴系中线垂直偏差由12 mm降至技术规范允许范围。经系泊试验与海上试航验证,各轴承温度、振动参数及功率输出均符合标准要求。本案例可为大型船舶轴系故障修复提供参考。
Regarding the intermediate shaft fracture accident of a certain DWT45000 oil tanker in the South China Sea,through the systematic detection and mechanical analysis of the causes of the intermediate shaft fracture,this article reveals the key causes of the centerline deviation of the shafting.The three-dimensional laser measurement technology was adopted to precisely calibrate the axis of the mainframe-shafting system,and a repair scheme for the overall settlement of the mainframe base based on the epoxy resin casting process was proposed.After the repair,the gear deflection difference of the main unit decreased from 0.51mm to 0.15mm,and the vertical deviation of the centerline of the shafting system decreased from 12mm to the allowable range of the technical specification.Verified by mooring tests and sea trials,the temperature,vibration parameters and power output of each bearing all meet the standard requirements.This case can provide a reference for the repair of shafting faults in large ships.
