The invention provides a shafting centering device and a shafting centering method.The shafting centering device comprises a micro-alignment telescope and a light target assembly, the central axis of the micro-alignment telescope coincides with the extension line of the central axis of a marine main engine flywheel, the cross center of a light target in the light target assembly coincides with the center of the end face of a stern shaft tube roughly, and the cross center of the light target in the light target assembly coincides with the center of the end face of the stern shaft tube roughly. The cross center of the light target coincides with the cross sight line center of the micro-alignment telescope. By means of the shafting centering device, in the ship repairing operation process, under the condition that shafting bow and stern datum points do not exist, the center of the broken end face of the stern shaft tube can be repositioned, the installation precision of the thickness stern shaft tube and the shafting center is guaranteed, and the service life of a ship after being repaired is prolonged.
本申请提供了一种轴系找中装置及轴系找中方法,轴系找中装置中包括测微准直望远镜和光靶组件,其中,测微准直望远镜的中心轴线与船舶主机飞轮的中心轴线延长线重合,光靶组件中的光靶的十字中心与艉轴管的端面中心粗重合,光靶的十字中心与测微准直望远镜的十字视线中心重合。利用本申请的轴系找中装置,在修船作业过程中,能够解决在没有轴系艏艉基准点的情况下,重新定位艉轴管断后端面的中心,保证了厚度艉轴管与轴系中心的安装精度,提高船只修理后的使用寿命。
