Technical Field
[0001] The utility model relates to the technical field of shipbuilding, in particular to a device for installing a dial indicator for measuring the coaxiality of a ship shaft positioning light target. Background Art
[0002] During shipbuilding, shafting requires precise installation to ensure proper propeller operation. Optical target installation helps determine the precise position of the stern tube, providing a benchmark for subsequent shafting installation. For example, on large ships, the stern tube installation tolerance requirements are very strict, typically limiting axial deviation to within ±0.5mm and radial deviation to an extremely small range. Optical target installation effectively ensures this precision.
[0003] The installation accuracy of the stern tube directly impacts a vessel's navigational performance. Improper installation can lead to vibration, increased wear, and other issues in the shafting system. Light target installation is a key step in achieving high-precision stern tube installation, minimizing energy loss during navigation, improving propulsion efficiency, and reducing fuel consumption.
