THE ALIGNMENT OF SHIP'S LINE SHAFTING

When it is necessary to examine the alignment of line shafting, in particular after a ship has grounded or after major repair work, the necessary equipment and data are usually available but instructions on the necessary procedures are not. The object of this article is to rectify this omission. The need for trouble-free alignment, particularly important in geared installations, and for achieving this after making a thorough study <usual for new ships since about 1960> aimed at optimum alignment <instead of the old practice of squaring up the flanges before coupling, a practice leading to trouble in service>, is explained. factors influencing the alignment of the shafting in service, the effects of misalignment, the calculation of the bending line, and some general principles for carrying out the alignment in new ships or after major repairs, are discussed. The jacking test is described and dis-cussed in some detail.
