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

[0028] This embodiment provides an installation and adjustment device for the base of the intermediate bearing of the ship's shafting system, which is suitable for height adjustment between the base of the intermediate bearing of the main engine's shafting system in the shipbuilding field and the base. The material produced 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.

[0029] The installation and adjustment device of this embodiment is composed of two parts: a fixed area and an adjustment area. The fixed area is composed 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 thereof. The width of the fixed slot is greater than the thickness of the bearing base 8. The lower plate of the fixed bas...

Embodiment 2

[0032] This embodiment provides a method for installing and adjusting the base of the intermediate bearing of the shafting of a ship. The installation and adjustment device for the base 9 of the intermediate bearing of the shafting of a ship in Embodiment 1 is used, and the steps are as follows:

[0033] 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 bolt 3, the jacking adjustment bolt 4, and the pressing down adjustment bolt 5;

[0034] Step 2. Adjust the distance between the fixing bolt 3 and the upper plate of the fixed base 2 to be slightly larger than the thickness of the bearing base 8, and adjust the distance between the jacking adjustment bolt 4 and the lowering adjustment bolt 5 to be slightly larger than the bearing base 9 thicknesses;

[0035] Step 3. Put the installation and adjustment device in place, the jacking adjustment bolt 4 and the down-pressing...

Abstract

The invention discloses a ship shafting intermediate bearing base installation adjusting device which comprises a fixing base, a stress rod, a fixing bolt, a jacking adjusting bolt and a pressing adjusting bolt, a fixing clamping groove is formed in the fixing base along one side, a fixing threaded hole is formed in a lower plate of the fixing base, and the fixing bolt is installed in the fixing threaded hole. The stress rod is installed on the other side of the fixing base, an adjusting nut is welded to the top of the fixing base, the jacking adjusting bolt is installed in the adjusting nut,an adjusting threaded hole is formed in the top of the stress rod, and the pressing adjusting bolt is installed in the adjusting threaded hole. By arranging the fixing base and the fixing bolts, the bearing base can be directly fixed to the bearing base, waste of materials and labor hours caused by welding work is avoided, subsequent re-grinding and paint spraying work is reduced, and damage to the bearing base due to high welding temperature is avoided.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a device for installing and adjusting a base of a ship shafting intermediate bearing. Background technique [0002] The load capacity of modern freight ships is increasing. In order to ensure sufficient power, more and more powerful ship power propulsion equipment (main engine) will follow. The high-power main engine will inevitably lead to a huge main engine shape. In order to ensure the high-speed linearity of the hull, the layout of the cabin is reasonably arranged, resulting in the characteristics of the main engine front and the shaft system being long. In order to ensure the transmission efficiency and force stability of the long shaft system, Intermediate bearings need to be installed in the long shaft system, and the installation accuracy of the intermediate bearings needs to be guaranteed. [0003] During the installation process of the intermediate be...
