[0002] The load capacity of modern cargo ships is getting bigger and bigger. In order to ensure sufficient power, the ship propulsion equipment (main engine) with higher and higher power is also coming. The high-power main engine will inevitably make the main engine appearance huge. In order to ensure the high-speed linearity of the hull and arrange the cabin layout reasonably, the main engine is forward and the shaft system is long. In order to ensure the transmission efficiency and force stability of the long shaft system, it is necessary to set an intermediate bearing in the long shaft system, and the installation accuracy of the intermediate bearing needs to be guaranteed.

[0003] During the installation of the intermediate bearing, the bearing base needs to be adjusted frequently to ensure installation accuracy. The conventional adjustment method of the bearing base is to temporarily weld the nut to the bearing base, then connect the bolts of the same specifications to the nut, and then adjust the height of the bearing base by rotating the bolts to raise and lower them. Therefore, the preparation work of the conventional method is cumbersome, and welding can easily cause thermal stress in the bearing base, causing quality risks, and the accuracy of the base position cannot be effectively guaranteed. In addition, after the bearing is installed, the temporarily welded nuts need to be cut, polished and repainted, which wastes a lot of man-hours and reduces work efficiency.

[0004] For this reason, a ship intermediate shaft system intermediate bearing mounting seat is proposed, which is upgraded and modified on the basis of the device to solve these shortcomings. Utility Model Content
