| 摘要:针对某船用齿轮箱试验时振动性能不达标的问题，根据振动情况列出可能导致振动不达标的潜在因素，并据此确定查找方案及改进措施。结果表明:基座联接处紧固件扭力不达标，管路悬伸过长，管路附件抖动；齿轮箱内部旋转件平衡等级设计不合理；齿轮箱装置台架热对中不佳是引起齿轮箱装置振动不达标的主要原因。改进措施实施后振动不达标问题得到有效解决。 |

| Abstract:The vibration performance of a marine gearbox could not meet with the standards, to deal with this problem, the factors which may lead to this problem were listed, and the investigation scheme and improvement measures were determined. The results showed that the main reasons for the problem were:the torque of the fasteners at the joint of base didn't meet with the standard, the over-hanging pipeline is too long, the accessories of the pipeline shook; the balance level of the internal revolving parts of the gearbox was not well designed,and the hot alignment of the gearbox bench was bad. The vibration problem was finally solved with the improvement measures. |
