Method for mounting shipping stern shaft tube lining

Abstract

The present invention provides a method for mounting shipping stern tube bushing, the bushing mounting position of the shipping stern tube processes to an epoxide resin plug hole, inner diameter of stern shaft tube is smaller than outer diameter of bush which is placed in lining mounting position of stern shaft tube, the bush is adjusted to location and gap between outer edge of two ends of lining and stern shaft tube is sealed, filling liquid epoxide resin in chamber betwwen lining and stern shaft tube by epoxide resin plug hole, the lining is exactly fixed in the stern shaft tube by solified epoxide resin. The mounting method of shipping stern tube lining has safe, credible characteristics, and shortens mounting cycle, reduces power strength.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a method for installing a stern tube bushing during shipbuilding. Background technique [0002] In shipbuilding, the bushing installation of ship stern tube is an important construction project. The installation quality of the stern tube bush directly affects the normal use of the ship. In the prior art, the traditional stern tube bushing installation method is mainly used to install the ship stern tube bushing. The traditional installation method of the ship stern tube bushing is to first bore the stern tube, and then machine the outer diameter of the bush according to the inner diameter of the bored stern tube. During the processing, a 0.02-0.05 mm interference, the bushing after processing is pressed into the stern tube by a special press-fitting tool. [0003] This traditional ship stern tube installation method has the following disadvantages: [0004] ① The installation process of the fr...

AI Technical Summary

Problems solved by technology

[0004] ①The installation process of the front and rear bushings of the entire ship stern tube takes a long period of time, and requires the use of many special equipment such as hydraulic jacks, threaded screw rods, etc., the process is cumbersome, and the labor intensity of workers is also relatively high

[0005] ②The installation quality of the front and rear bushings of the ship stern tube is greatly affected by man-made, which requires high professional skills for the workers, especially the machining and measurement personnel, and it is difficult to effectively guarantee the installation quality of the front and rear bushings

[0006] ③It is also very easy to cause bushing scrapping accidents. During the installation process, the installation quality may decline or the entire bushing will be scrapped due to the negligence of mechanical processing or construction personnel.
