Problems solved by technology
In this installation method, the thickness of the two pads is relatively thin, and the strength is poor and easy to crack
At the same time, there are three contact surfaces in this method, the contact stiffness is low, and the reliability is poor, which can no longer meet the construction needs of high-power cutter suction ships

Embodiment Construction
[0049] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0050] In this embodiment, the cutter shafting of a cutter suction dredger with a cutter power of 5000kw is taken as an example, as figure 1 As shown, in the direction from the bow to the stern, the reamer shaft system includes two driving motors 1, two clutches 2, a gearbox 3, 1# intermediate shaft 4, 1# intermediate bearing housing 5, and 2# intermediate shaft 6. 2# intermediate bearing seat 7, 3# intermediate shaft 8, 3# intermediate bearing seat 9, 4# intermediate shaft 10, reamer shaft 11 and reamer bearing seat 12; each drive motor 1 is connected with a clutch 2 connection; both clutches 2 are connected with the gearbox 3.
[0051] On the basis of the above-mentioned reamer shafting system, the present invention uses the following meth...

Abstract
The invention relates to the technical field of ship building and repairing and provides an alignment and mounting method for cutter suction dredger reamer shafting. The cutter shafting sequentially comprises two drive motors, two clutches, a gearbox, a 1# intermediate shaft, a 1# intermediate bearing seat, a 2# intermediate shaft, a 2# intermediate bearing seat, a 3# intermediate shaft, a 3# intermediate bearing seat, a 4# intermediate shaft, a 4# intermediate bearing seat, a reamer shaft and a reamer bearing seat. In the alignment and mounting method, a shafting theoretical center line is positioned by a stay wire, various equipment, including an irradiation tool, an autocollimator and a laser shaft alignment instrument, of the shafting are arranged for alignment; and in addition, through arrangement of a false shaft tool, a regulation gasket, a temporary supporting device and replacement of two cushion blocks with one cushion block, favorable conditions are provided to alignment regulation of the shafting. The alignment and mounting method provided by the invention is high in accuracy, liable to operate, long in service life and strong in reliability, can shorten the ship construction period and can prolong the whole life period of the whole set of systems.
Description
technical field [0001] The invention relates to the field of ship repairing and building, in particular to a method for aligning and installing the cutter shafting of a cutter suction dredger. Background technique [0002] As one of the core components of a large cutter suction dredger, the cutter shafting is essential for alignment calculation and analysis in its design stage. At present, domestic and foreign research institutes have not provided normative guidance on the alignment of dredging equipment shafting. Therefore, for the alignment and installation of cutter shafting of cutter suction dredgers, especially for high-power cutter shafting There are mainly the following problems: [0003] First: Due to the large shaft diameter and heavy weight of the reamer shafting system, it is impossible to crank the shafting system during the shafting alignment process. At present, most shipyards use the zigzag offset method for shafting alignment, that is, by adjusting the "open...
