Abstract

The invention relates to the technical field of shipbuilding, the invention discloses an installation and alignment process of a ship shafting, including the pre-installation of the ship's shafting, centering alignment of coupling flanges of propeller shaft and countershaft, the alignment of intermediate shaft and clutch flange, the alignment of clutch flange and diesel engine, the pouring of epoxy gasket under the base of diesel engine, the adjustment and installation of rotor coupling on shaft belt generator, the alignment of shaft belt generator and intermediate shaft, and the measurement of bearing load; at the pouring step of the epoxy gasket under the base of the diesel engine main engine, according to the drying shrinkage amount of the epoxy gasket, the mounting height of the dieselengine main engine is corrected to be the sum of the theoretical mounting height and the dry shrinkage amount; the amount of drying shrinkage of the epoxy gasket is obtained by drying shrinkage testdata of the epoxy gasket material. The invention improves the installation precision of the ship shafting, and improves the operation reliability of the ship shafting equipment.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a process for installing and aligning ship shafting. Background technique [0002] The shafting of a ship refers to the general term for the power transmission components from the output end of the main engine of the diesel engine to the propeller. The shafting of a typical large ship includes parts such as a propeller shaft, an intermediate shaft, a thrust shaft, a clutch, a main engine of a diesel engine, and bearings for supporting rotating parts in the shafting. [0003] The shafting of the ship needs to be corrected during installation, so that each shafting component has good alignment accuracy and ensures the normal and stable operation of the shafting equipment. The existing ship shafting installation and correction process still has shortcomings such as low installation accuracy and low installation efficiency, so it is necessary to improve the process on the basis...
