学习一下MAN是怎么做的

将主机轴系初步调整好, 达到轴系校中报验状态未穿轴系螺检测时, 先测量主机机内后三档主轴承的间隙, 并记录下来.主机轴系校中好, 同时轴系螺丝拉紧报船东和船检后, 将中间轴承的负荷调整到, 让中间轴承的下轴瓦与中间轴相贴, 并用顶丝将中间轴承承座顶起, 同时左右的顶丝把紧, 让中间轴承的下轴瓦以的支撑力支撑起中间轴。这时, 再次测量主机后三档轴承的间隙

我做过，还要记录环境温度以及船的吃水深度，

Sorry, I'm talking about jack up test!

不懂这行的。我是搞电气的。

about jack up test:you only need to take the procedure of shaft calculation from design dpt.

i want to know this also. in the sea trial plan, the main bearing load should be messured , i do not know how to measure.

主轴承负荷的工装，一般主机厂家都会提供的，是一只工字梁。

可不可以描述详细点，我们想自己做个工装。

Reply 6 floor:What I have only shafting alignment calculation,there is not any procedure for doing the jack up test for main bearings.As I know, only shafting jack up test details provides in such calculation.Now my situation is in ship repair,we do not have such dpt in our yard,both the tail shaft fwd and aft bearings were damaged completely.We were requested to do shafting realignment and jack up tests.Which worries me the most is the test for main bearings,I don't know if any special tools will be needed or even where to put the tools.Please give me a hand if you know much in the fields.Thanks a lot!
