Embodiment Construction

[0019] A shafting centering process improvement method for shipbuilding of the present invention will be further described in detail in conjunction with the accompanying drawings, but the protection scope of the present invention cannot be limited by this.

[0020] please see figure 1 , figure 1 It is a schematic flow chart of a shafting alignment process improvement method for shipbuilding in the present invention. It can be seen from the figure that the present invention is an improved method for shafting centering process used in shipbuilding.

[0021] Compared with the existing technology, the improvement of the method of the present invention mainly includes boring the stern shaft flange 1 and the intermediate shaft stern flange 2 in the workshop, and carrying out the intermediate shaft front flange 3 and the output end flange of the main engine on the platform. 4, adjust the meandering (GAP) and offset (SAG) of the stern shaft flange 1, the intermediate shaft stern fla...

Abstract

The invention relates to a method for improving a shaft system centering process for ship building. The method comprises the following steps of: boring holes on a screw shaft flange, a middle screw shaft flange, a middle shaft front flange and a host machine output end flange; adjusting the tortuosity and deviation of the screw shaft flange and the middle screw shaft flange and the tortuosity and deviation of the middle shaft front flange and the host machine output end flange; and connecting the host machine output end flange and the middle shaft front flange and connecting the middle screw shaft flange and the screw shaft flange through bolts, and the like. The method of the invention has the advantages of greatly shortening the working time of the shaft system after a ship is undocked, lowering the pressure of a dock mooring test and contributing to shortening the mooring test period of a dock of a company.

Description

technical field [0001] The invention relates to shipbuilding, in particular to an improved method for shafting centering process used in shipbuilding. Background technique [0002] Currently, in shipbuilding, it is necessary to align the shafting of the ship. Among them, the centering work mainly adopts the following process methods: [0003] In the dock, operations such as shafting boring, plug shaft, intermediate shaft lifting, and main engine lifting are completed. After the ship is undocked, the construction completes the flange boring of the main engine and the intermediate shaft and the intermediate shaft and the stern shaft, the adjustment and submission of the shafting bending (GAP) and offset (SAG), the main engine and the intermediate shaft and the intermediate shaft and the stern shaft Shaft bolted connections, shafting load measurement. [0004] These works have greatly affected the mooring test cycle of the ship. Based on this, in order to shorten the workin...
