Embodiment Construction
[0022] Below in conjunction with accompanying drawing example the present invention is described in further detail:
[0023] Such as figure 1 Shown is a schematic diagram of the installation of the stern shaft of the present invention. The stern shaft includes a boss installed under the hull 1 and a stern shaft extension section 2 extending out of the boss. The hull 1 is welded with two intermediate bearings at its bottom. The bracket 3 of the installation hole, the extension section 2 of the stern shaft passes through the intermediate bearing installation holes of the two brackets 3 through two intermediate bearings 4 sleeved thereon.
[0024] The operation steps of this method for correcting the installation hole of the intermediate bearing in the middle of the stern shaft include:
[0025] A. Carry out boring processing to the middle bearing installation hole of each bracket 3 through the mobile boring machine of the ship's berth;
[0026] B. Detect the angle between the ...

The invention discloses a correction method for intermediate bearing installation holes of a stern shaft. The stern shaft comprises a boss installed below a ship body and a stern shaft extending section extending out of the boss, multiple brackets with the intermediate bearing installation holes are arranged at the bottom of the ship body, the stern shaft extending section penetrates through the intermediate bearing installation holes of the multiple brackets through multiple intermediate beatings arranged on the stern shaft extending section in a sleeving mode, the external circles of the intermediate bearings are turned through an eccentric turning clamp, the special intermediate bearings are inserted into the intermediate bearing installation holes of the corresponding brackets, and the stern shaft extending section sequentially penetrates through the special intermediate bearings of the intermediate bearing installation holes of the multiple brackets. Compared with the prior art, the method can solve the problem that as an included angle exists between the axes of intermediate bearing installation holes of brackets supporting a stern shaft and the axis of the stern shaft in the prior art, the service life of the stern shaft is shortened.
Description
technical field [0001] The invention relates to the technical field of ship processing, in particular to a method for correcting an intermediate bearing installation hole when a ship stern shaft device is installed. Background technique [0002] The stern shaft device is one of the important devices for mooring a ship. figure 1 Shown stern shaft, this stern shaft includes the boss that is installed on the bottom of the hull 1 and stretches out the stern shaft extension section 2 of the boss and the propeller 5 that is located at the tail of the stern shaft extension section 2, and the hull 1 Two brackets 3 with intermediate bearing mounting holes are provided at its bottom, and the stern shaft passes through the intermediate bearing mounting holes of the two brackets 3 through the intermediate bearing 4 sleeved thereon. The role played by the stern shaft is to transmit the power output by the main engine of the ship to the propeller 5 so as to promote the movement of the sh...
