Abstract

The invention provides a centering method for ship shafting equipment. The method comprises devices such as a centering tool and centering equipment, wherein the centering tool comprises a centering tube; and two ends of the centering tube are sleeved by a left adjustment ring and a right adjustment ring respectively. The centering method mainly comprises the steps including determination of a theoretical shafting center line, setting of the centering tool, centering of the axis of the centering tube and the theoretical shafting center line, and installation and centering of a reduction gear box and equipment. The method provided by the invention has the advantages of high accuracy, low cost, high operability, a short equipment installation cycle, etc.

Description

technical field [0001] The invention relates to the centering of ship shafting, in particular to a method for centering ship shafting equipment. Background technique [0002] In special ship types where the shafting is arranged above the main deck, such as figure 1 As shown, the entire shaft system of the ship is composed of a reduction gearbox 1 and a plurality of equipment 2, and the rotating shafts of the equipment 2 are all hollow. In the existing technology, according to the previous centering method of the shafting of this type of ship, an installation datum is first positioned on the theoretical center line of the shafting by means of pulling wires and lighting; Install in place, then install the air duct propeller backwards with the reduction gearbox as a reference, and install each device one by one forward. Since the equipment is installed in a single location, the installation method of the above-mentioned shafting equipment will lead to a long installation peri...
