Correction method for intermediate bearing installation holes of stern shaft

The invention discloses a correction method for intermediate bearing installation holes of a stern shaft. The stern shaft comprises a boss installed below a ship body and a stern shaft extending section extending out of the boss, multiple brackets with the intermediate bearing installation holes are arranged at the bottom of the ship body, the stern shaft extending section penetrates through the intermediate bearing installation holes of the multiple brackets through multiple intermediate beatings arranged on the stern shaft extending section in a sleeving mode, the external circles of the intermediate bearings are turned through an eccentric turning clamp, the special intermediate bearings are inserted into the intermediate bearing installation holes of the corresponding brackets, and the stern shaft extending section sequentially penetrates through the special intermediate bearings of the intermediate bearing installation holes of the multiple brackets. Compared with the prior art, the method can solve the problem that as an included angle exists between the axes of intermediate bearing installation holes of brackets supporting a stern shaft and the axis of the stern shaft in the prior art, the service life of the stern shaft is shortened.
