[0019] 1 Measurement of centerline of ship shafting.

[0020] 1.1 Overview

[0021] The ship has 3 shaft systems, namely the left and right side shaft systems and the midship shaft system. The left and right side side shafts are respectively 5785mm away from the midship, the tail of the side axis is 970mm above the baseline at #8-100 (3900mm towards the bow of #0), and the height of the bow is 970mm above the baseline at #33+100 (16600mm towards the bow of #0) 1100mm, the inclination angle between the axis and the baseline is about 0.7574°; the central axis is located in the midship, the longitudinal axis coincides with the midship, the tail of the central axis is 970mm above the baseline at #4 100 (1900mm from #0 to the bow), and the bow is at #33(# 0 to the bow (16600mm) is 1100mm above the baseline, and the inclination angle between the axis and the baseline is about 0.5961°.

Abstract

The invention relates to a method for mounting ship three-engine three-propeller engine shaft system, belonging to ship main shaft mounting technical field. The invention arranges a target support, tests the central line of the shaft system, positions and mounts stern axle tube, and mounts stern axle and propeller or the like, to confirm the installment accuracy of shaft system, and overcome the defects of prior art as hard control on installment size, large size error, and long installment period, to provide better art technical assurance to ship production.

Description

technical field [0001] The invention relates to a method for installing a main engine shafting system, in particular to a method for installing a main engine shafting system with three main engines and three propellers in a ship. Background technique [0002] The stern shaft drives the propeller. Its shaft installation is relatively easy. In order to meet the force requirements of large-scale transportation with a concentrated load of more than 500 tons, and to meet the force requirements of uniformly distributed loads of transport trucks, some ships are propelled by three engines and three propellers, and diesel engine power devices arranged in the middle and tail models the design of. The output end of each main engine drives the propeller through couplings, reduction gearboxes, intermediate shafts, stern shafts, etc. The shaft system is equipped with intermediate shaft, intermediate bearing, stern shaft, stern bearing, front and rear sealing devices and manual brake de...
