Problems solved by technology

Therefore, the preparation work of the conventional method is cumbersome, and welding is likely to cause thermal stress on the bearing base, causing quality risks, and the accuracy of the base position cannot be effectively guaranteed
In addition, after the bearing installation is completed, the temporarily welded nuts need to be cut, polished and repainted, which wastes a lot of man-hours and reduces work efficiency

Embodiment 1

[0034] This embodiment provides an installation and adjustment device for the base of the intermediate bearing of the ship shafting, which is suitable for the height adjustment between the base and the base of the intermediate bearing of the main shaft of the main engine in the ship field. The materials generated by the bearing adjustment method cannot be recovered and the working hours are wasted, and the problem of damage to the bearing base 9 caused by the heat generated in the welding process is avoided, and the work efficiency is improved.

[0035] The installation and adjustment device in this embodiment consists of a fixed area and an adjustment area. The fixed area consists of a fixed base 2 and a fixed bolt 3 . The fixed base 2 is welded by three steel plates. The fixed base 2 is provided with a fixed slot along one side. The width of the fixed slot is greater than the thickness of the bearing base 8. The lower plate of the fixed base 2 is provided with a fixed threade...

Embodiment 2

[0038] This embodiment provides a method for installing and adjusting the base of the intermediate bearing of the ship shafting, using the installation and adjustment device of the base 9 of the intermediate bearing of the ship's shafting in Embodiment 1, and the steps are as follows:

[0039] Step 1. According to the thickness of the bearing base 8 and the distance between the bearing base 9 and the bearing base 8, determine the lengths of the fixing bolts 3, the lifting adjustment bolts 4 and the depression adjustment bolts 5;

[0040] Step 2. Adjust the distance between the fixing bolt 3 and the upper plate of the fixing base 2 to be slightly larger than the thickness of the bearing base 8, and adjust the distance between the lifting adjusting bolt 4 and the pressing adjusting bolt 5 to be slightly larger than the bearing base 9 thickness;

[0041] Step 3. Put the installation and adjustment device in place, the lifting adjustment bolt 4 and the depression adjustment bolt 5...

Abstract

The invention discloses a method for installing, adjusting and assembling an intermediate bearing base of a ship shafting system. A special installation and adjusting device is adopted. The lengths of the fixing bolts, the jacking adjustment bolts and the lowering adjustment bolts; Step 2, adjust the distance between the fixing bolts and the upper plate of the fixed base to be slightly larger than the thickness of the bearing base, and adjust the distance between the lifting adjustment bolts and the lowering adjustment bolts. Adjust the distance between the bearings to be slightly larger than the thickness of the bearing base; Step 3, place the installation and adjustment device in place; Step 5, set the installation and adjustment device at the left front, left rear, right front, and right rear of the bearing base and the bearing base; Step 6 , Tighten the fixing bolts, push down the adjustment bolts, and lift the adjustment bolts to complete the fixing. The invention is convenient to use, is made of steel and bolts and nuts, and has the same adjustment cost as the existing bearing base, and only needs to be produced once and can be reused for many times.

Description

technical field [0001] The invention belongs to the technical field of ship construction, and in particular relates to a method for installing and adjusting a base of an intermediate bearing of a ship shafting. Background technique [0002] The carrying capacity of modern freight ships is getting larger and larger, and in order to ensure sufficient power, the power propulsion equipment (main engine) of ships with increasing power also comes along. The high-power main engine will inevitably result in a huge shape of the main engine. In order to ensure the high-speed linearity of the hull, the layout of the cabin is reasonably arranged, which creates the characteristics of the main engine being forward and the shaft system being long. In order to ensure the transmission efficiency and force stability of the long shaft system, The intermediate bearing needs to be set in the long shaft system, and the installation accuracy of the intermediate bearing needs to be ensured. [000...
