One is the common oil lubrication, and the other is water lubrication, that is, the bearings supporting the shaft sections are immersed in sea water or river water during operation.

[0003] In water lubrication, in order to prevent seawater or river water from corroding the shaft section, a copper sleeve is usually installed on the shaft section, and then the bearing sleeve is installed outside the copper sleeve, so as to prevent the shaft section from directly contacting water. At present, when installing the copper sleeve, a heat-insertion process is usually adopted, that is, the copper sleeve is first heated, and the copper sleeve is expanded by heat before being installed on the shaft section to achieve an interference fit between the copper sleeve and the shaft section.

[0004] In the prior art, when the copper sleeve is inserted into the shaft section, the copper sleeve cannot quickly achieve coaxial positioning with the shaft section, the copper sleeve cannot ensure high coaxiality with the shaft section during movement, and the copper sleeve is often cooled by natural cooling after insertion, which takes a long time.
