Problems solved by technology

[0003] The propeller tail shaft system is an important component structure in a ship. When a new ship is built, the installation of the propeller tail shaft system is the top priority. Large errors make it difficult to accurately locate and affect the overall stability of the propeller tail shaft system. Therefore, the present invention proposes an oil-lubricated propeller tail shaft system installation process to solve the problems existing in the prior art

Embodiment 1

[0059] according to figure 1 As shown, the present embodiment proposes an oil-lubricated propeller tail shaft system installation process, including the following steps:

[0060] Stern tube installation: locate the stern tube reference, determine the steel wire deflection, prepare for the stern tube installation, perform stern tube positioning, herringbone support arm positioning and stern tube fixation;

[0061] Stern tube bearing installation: carry out bearing inspection, clean and install the bearing;

[0062] Tail shaft installation: detect the tail shaft, clean and install the tail shaft, and inspect the installation;

[0063] Tail sealing device installation: use purchased standard parts;

[0064] Propeller installation: Detect the cooperation between the propeller and the tail shaft, and install the propeller into the tail shaft;

[0065] Installation of the first sealing device: adjust the shell of the first sealing device to be coaxial with the tail shaft;

Embodiment 2

[0069] according to figure 1 , 2 As shown, the present embodiment proposes an oil-lubricated propeller tail shaft system installation process, including the following steps:

[0070] The specific reference for positioning the stern tube is as follows: the positioning reference of the stern tube is the theoretical center line of the shaft system. Before the installation of the stern tube, according to the layout requirements of the shaft system, pull the steel wire on the theoretical center line of the shaft system. The steel wire is a piano wire. The selection is 75% of the breaking force of the steel wire; the relationship between the diameter of the steel wire and the pulling force is shown in the following table:

[0071]

[0072] Determining the deflection of the steel wire is specifically as follows: use the drawn steel wire to determine the axis of the shafting, and eliminate the deflection caused by the steel wire’s own weight. The calculation formula is as follows:...

Abstract

The invention provides an oil-lubricated propeller tail shaft system mounting process, which relates to the technical field of ship mounting and comprises the following steps: mounting a tail shaft tube: positioning a reference for the tail shaft tube, determining the deflection of a steel wire, preparing before mounting the tail shaft tube, positioning the tail shaft tube, positioning a propeller strut support arm and fixing the tail shaft tube; mounting a tail shaft tube bearing: detecting the bearing, cleaning and mounting the bearing; when the tail shaft tube is installed, the positioning reference of the tail shaft tube is determined, the deflection of the steel wire is determined, then the tail shaft tube is positioned and fixed, the positioning reference of the tail shaft tube is the theoretical center line of the shaft system, before the tail shaft tube is installed, according to the arrangement requirement of the shaft system, the steel wire of the theoretical center line of the shaft system is pulled, the steel wire is a piano wire, and the tensile force of the steel wire is 75% of the tensile strength of the steel wire. Meanwhile, the axis of the shaft system is determined by drawing the steel wire, and the deflection is calculated, so that the deflection caused by the dead weight of the steel wire is eliminated, the positioning accuracy of the tail shaft tube is improved, and the overall stability of the propeller tail shaft system is ensured.

Description

technical field [0001] The invention relates to the technical field of ship installation, in particular to an installation process of an oil-lubricated propeller tail shaft system. Background technique [0002] Ship is the general term for various ships. A ship is a means of transportation that can sail or berth in waters for transportation or operation. It has different technical performance, equipment and structural types according to different requirements. In addition, civilian ships are generally called ships, military ships are called ships, small ships are called boats or boats, and they are collectively called ships or boats. The interior mainly includes accommodation space, support structures and drainage structures. The propulsion system using external or self-contained energy is generally a streamlined envelope that is conducive to overcoming fluid resistance. The material is constantly updated with technological progress. In the early days, it was made of natural...
