The invention discloses a ship propeller shaft horizontal lapping-in installation method which specifically comprises the following steps: S1, obtaining machining size information of a propeller shaft cone part, measuring the machining size of the propeller shaft cone part, and machining the machining size which does not meet the requirement; s2, in the dock building stage of the ship, a propeller shaft is installed in a ship stern tube bearing, and then a propeller is hoisted to the stern; the propeller is pre-installed on the propeller shaft cone part through a chain block or a hydraulic installation trolley; s3, a hydraulic nut is pre-installed on a propeller shaft on the outer side of the propeller, and in the horizontal state of the propeller shaft, grinding-in of the propeller shaft and a propeller taper hole is conducted; and S4, after grinding-in of the propeller shaft and the propeller taper hole is completed, a hydraulic nut is installed through a hydraulic oil cylinder, and installation of the propeller shaft is completed. According to the method, the propeller and the propeller shaft are horizontally ground and installed, the situation that the propeller needs to be turned over in an inner field or an outer field is avoided, a special tool does not need to be used, the working time and cost for grinding the propeller and the propeller shaft in the inner field are saved, and the ship building period is shortened.

    本发明公开了一种船舶螺旋桨轴水平研配安装的方法,该方法具体包括如下步骤:S1,获取螺旋桨轴锥部的加工尺寸信息,测量螺旋桨轴锥部的加工尺寸,并对不符合要求的加工尺寸进行加工;S2,船舶在船坞建造阶段,将螺旋桨轴安装在船舶艉管轴承内,再将螺旋桨吊装至船艉处;利用手拉葫芦或液压安装小车将螺旋桨预安装在螺旋桨轴锥部上;S3,在螺旋桨外侧的螺旋桨轴上预安装液压螺母,在螺旋桨轴水平状态下,进行螺旋桨轴和螺旋桨锥孔的研配;S4,螺旋桨轴和螺旋桨锥孔的研配完成后,通过液压油缸安装液压螺母,完成螺旋桨轴的安装。本发明通过螺旋桨和螺旋桨轴水平研配安装,节省了需要在内场或者外场将螺旋桨翻身,无需使用特制工装,节省了螺旋桨和螺旋桨轴在内场研配的作业时间和成本,缩短了船舶建造周期。
