Problems solved by technology

Its main components are: thrust shaft and its bearing, intermediate shaft and its bearing, stern shaft (or propeller shaft) and stern bearing, herringbone frame bearing, stern shaft tube and sealing device, and the coupling of each shaft has two or A shaft system with more than two intermediate shafts. It is called the long shaft system, the flexibility of the long shaft system is relatively good, and it is easier to adjust, but the workload of adjustment and installation is large, the installation period is long, and the installation accuracy is difficult to control

Embodiment Construction

[0015] The engine room of the VS483-MKII ship is located at the bow, and it adopts the propulsion method of two engines and two propellers. The main propulsion shafting system is divided into two groups on the left and right, and each group of shafting systems includes a reduction gearbox, 7 high-speed intermediate shafts, 1 low-speed intermediate shaft, 1 propeller shaft, 1 low-speed intermediate bearing, 14 high-speed intermediate bearings and a set of stern tube. The port propeller rotates counterclockwise and the starboard propeller rotates clockwise (external rotation).

[0016] The total length of the shaft system is 57476mm, the center of the propeller is located at 3#+150, the front face of the flywheel end of the main engine is located at 86#+226, the end face of the output flange of the gearbox is located at 27#+50 (10# front rib distance is 600mm, 10#~113# The distance between the ribs is 700mm, and the distance between the ribs after 113# is 600m...

Abstract

The invention relates to a mounting method of a ship long axis system. Technical measures are respectively taken for the mounting processes and the mounting precision control of the mounting of the ship long axis system in all mounting stages of an inner site stage, a slipway construction stage and an axis system mounting and aligning stage to ensure that the mounting and the aligning of the axis system smoothly meet check and accept requirements, and the mounting and aligning period of the axis system is shortened so as to shorten a ship construction period.

Description

technical field [0001] The invention relates to a method for installing a long shaft system of a ship. Background technique [0002] Ship shafting generally refers to the transmission device starting from the flange at the end of the main engine crankshaft (or at the end of the reduction gearbox) to the tail shaft (or propeller shaft). Its main components are: thrust shaft and its bearing, intermediate shaft and its bearing, stern shaft (or propeller shaft) and stern bearing, herringbone frame bearing, stern shaft tube and sealing device, and the coupling of each shaft has two or A shaft system with more than two intermediate shafts. It is called a long shaft system. The long shaft system has better flexibility and is easier to adjust, but the workload of adjustment and installation is large, the installation period is long, and the installation accuracy is difficult to control.
