割螺母工艺流程

DISMANTLE TECHNICS OF TAIL SHAFT NUT

1、搭好架子。

2、尾轴露出来的牙保护好，确保尾轴螺母在割的过程中不伤到尾

轴的牙。

3、确保风灯和氧气是否到位。

4、开始割螺母，在螺母左右两端割出两个槽，宽度大约为200mm。

割到单边深度大约离牙底20mm时停下检查螺母状况。然后，再

慢慢割至离牙底大约5mm停止切割。

Start to cut the nut, first cutting two grooves P&S side of the nut, the width about is 200mm. When the one side depth about 20mm of screw thread bottom, stop cutting, inspection and measure.

continue to cut the nut very slowly, when the one side depth about 5mm of screw thread bottom, stop cutting.

5、螺母割完后，然后用150T的液压油顶置于割好的槽内，将螺母

胀开。挂好割开的螺母缓慢下放至坞底。

After finish to cut the nut, then use the 150T hydraulic jack puts in the groove to open the nut. Finally put the nut in the bottom of dock.

6、螺母割出后,尾轴螺纹做无损探伤，检查螺纹的变形情况。

After the nut removed, the screw thread of tail shaft must be dye check, inspection the condition of the screw thread 7、用Q235钢车制工具螺母，与备件螺母螺纹一致。

8、试装工具螺母，螺母安装过程必须顺畅，用手可一旋到底。

9. 新螺母和艉轴螺纹配合达到要求后，待螺旋桨压装后,再进行

艉轴螺母和螺旋桨后端的贴合情况进行拂配，螺旋桨螺母与螺

旋桨小端配合面0.05mm塞尺应插不进。
