The mounting method of shipping stern tube lining has safe, credible characteristics, and shortens mounting cycle, reduces power strength.
Description
Technical field
The present invention relates to shipbuilding, particularly a kind of method that stern shaft tube lining is installed in the ship building process.
Background technology
In the middle of ship building, it is an important project under construction that the lining of marine stern axle tube is installed.The installation quality height of this stern shaft tube lining directly affects the normal use of boats and ships.In the prior art, mainly adopt traditional stern shaft tube lining installation method to carry out the installation of shipping stern shaft tube lining.This traditional shipping stern shaft tube lining installation method is formerly the stern tube shaft pipe to be carried out bore hole; According to the stern tube shaft bore size behind the bore hole lining external diameter is carried out machine up then; Be placed with the magnitude of interference of 0.02-0.05mm in the course of processing, the lining after machining is pressed in the stern tube shaft pipe by the instrument that is press-fitted of special use again.
There is following shortcoming in this traditional marine stern axle tube installation method:
1. the installation process cycle of the forward and backward lining of whole marine stern axle tube longer, and need to use numerous specialized equipment such as hydraulic jacks, threaded screw rod etc., technological process is loaded down with trivial details, working strength of workers is also bigger.
2. the quality of the forward and backward lining installation of marine stern axle tube receives man's activity bigger, and is particularly very high to the professional skill requirement of machine up, survey crew to the workman, is difficult to effectively guarantee the installation quality of front and rear bushings.
3. but also the accident that lining processing is scrapped very easily takes place, each link all possibly cause installation quality to descend or the scrapping of whole lining in the installation process because of machine up or workmen's carelessness.
Summary of the invention
Technical matters to be solved by this invention is exactly the deficiency that will overcome prior art; A kind of new mode of mounting shipping stern shaft tube lining is provided; Method of the present invention has shortened the installation period of whole forward and backward lining in the ship building greatly; The reliable in quality, the installation effectiveness that make the installation process of lining smooth, install are high, and have reduced the use amount of specialized equipment, and workmen's labour intensity also reduces greatly.
