所谓“一步法”人字架焊装工艺,其特点是直接用加工好的艉轴和艉轴轴承作为定位基准,将人字架焊装到船上。这种工艺简单、方便,易掌握、不需专用设备,所需总工时少,可以有效地缩短船台周期。众所周知,在传统的工艺中,为了保证轴系内外轴承的同心度,焊好人字架后必须用搪排搪削内外轴承座的内孔。这种工艺费工多,周期长,所以不少船厂改为浇注环氧树脂定位工艺。将人字架的内孔加大,待人字架焊好后将外轴承装入其中,借助调整螺钉找正外轴承的 The so-called “one-step” herringbone welding process, which is characterized by direct use of the processed shaft and shaft bearings as a benchmark, the herringbone frame welded to the ship. This process is simple, convenient, easy to grasp, without special equipment, less total work hours, can effectively reduce the slipway cycle. As we all know, in the traditional process, in order to ensure the concentricity of the shaft bearing inside and outside, after welding a good frame of the human character must be used to enamel the inner and outer bearing housings. This process more labor, long cycle, so many shipyards instead casting epoxy positioning process. Will increase the inner diameter of the herringbone frame to be herringbone brackets welded into the outer bearing which, with the help of adjusting screws to find the outer bearing
