The invention provides a structural type long shaft manufacturing and machining method. A 'clearance aligning method' is adopted, end shafts are sleeved with a core pipe, pre-tightening is conducted through regulation bolts, verification is unceasingly conducted through a dial indicator in the core pipe rotation process till coaxiality of the core pipe and the end shafts meet the requirement, andthen fixation of the core pipe and the end shafts is completed through spot welding, sealing welding and the like. The structural type long shaft manufacturing and machining method is particularly suitable for synchronous machining and manufacturing of tooth shapes and key grooves of multiple rows of chain wheels on a super-wide machine groove single long shaft, the work efficiency can be improved, and the production and manufacture cost can be greatly reduced. 一种结构型长轴制造加工方法，采用"间隙调心法"，通过将端轴套入芯管中并用调节螺栓预紧，在转动芯管的过程中不断通过百分表进行校验，直到芯管与端轴同轴度达到要求，然后再采取点焊、封焊等完成芯管与端轴的固定。本发明提供的一种结构型长轴制造加工方法，特别适用于超宽机槽单一长轴上多排链轮齿型和键槽同步的加工制作，可提高工作效率
