The invention discloses a stern shaft hoisting process, which is convenient for limiting a stern shaft after the front end of the stern shaft and a sleeve penetrate out of a front bearing of a stern tube, and can strictly control the advancing direction of the stern shaft and ensure that the stern shaft and the stern tube are concentric. A group of sleeves are sleeved at the front end of the tail shaft before shaft penetrating, so that the sleeves can be conveniently limited when the front end of the tail shaft penetrates out of the front bearing of the tail tube and the sleeves penetrate through # 22, namely, the tail shaft can be limited at the front end in advance in the shaft penetrating process, the control interval of limiting the tail shaft in the shaft penetrating process is enlarged, and the uncontrollable risk of a middle section in the shaft penetrating process is reduced; the plastic gasket with the thickness of 1mm covers the front bearing, so that the front bearing is prevented from being scratched; the gap between the sleeve and the front bearing is checked, prevention and checking measures are added, and the safety and accuracy in the tail shaft hoisting process are improved.
本发明公开了一种艉轴吊装工艺,便于在艉轴前端及套筒穿出艉管前轴承后,对艉轴进行限位,该工装能严格控制艉轴的前进方向,保证艉轴与艉管同心;穿轴前,艉轴前端套有一组套筒,便于在艉轴前端穿出艉管前轴承前,套筒穿过#22时,对套筒进行限位,相当于穿轴过程中在前端能提前对艉轴进行限位,加大了穿轴过程对艉轴限位的控制区间,减少了穿轴过程中间段的不可控风险;用1mm厚的塑料王垫片覆盖在前轴承上,保护了前轴承免于擦伤;检查套筒与前轴承之间的间隙,增加了防范与检查措施,提高了艉轴吊装过程的安全性及精准性。
