Problems solved by technology

The deficiencies of the conventional shafting alignment method are: poor fitting between the shafting alignment accuracy and theoretical calculation results, and potential safety hazards
The reason for this is that there are many bearings on the shaft system, but the actual measured bearings are usually only 3 to 5, and the bearing load distribution is usually more complicated, which may lead to the fact that when the actual measured 3 to 5 bearing loads meet the requirements, Other bearings have large deviations from the theoretically calculated values, and during the entire on-site construction adjustment process, the actual curve state of the shafting system cannot be observed, that is, the actual adjusted curve and the theoretically calculated curve may deviate greatly, under different working conditions Risk of high temperature damage to the bearing during operation

Embodiment Construction

[0017] refer to figure 1 and figure 2 , the present invention is a ship propulsion shafting calibration method, which includes the following steps: S1: measuring the curvature of each section of the shafting 1 to create a shafting curve. S2: Set the measurement reference, and measure the relative position of each shaft system 1 relative to the measurement reference. S3: Create the relative position of the shafting curve and the measurement datum, and create the actual shafting curve. S4: Calculate the theoretical shafting alignment curve, create the relative position of the shafting alignment theoretical curve and the measurement reference, create the theoretical shafting curve, compare the actual shafting curve with the theoretical shafting curve, according to the actual shafting curve and Shafting calibration is carried out by fitting and comparing the theoretical shafting curve.

[0018] This ship propulsion shafting calibration method creates the actual shafting curve ...

Abstract

The invention discloses a ship propulsion shafting alignment method. The ship propulsion shafting alignment method comprises the steps that an actual shafting curve is created, in the whole site construction process, the actual shafting curve can be observed, the fitting degree of the shafting curve after actual adjustment and a theoretical shafting curve is increased, alignment accuracy during shafting installation is improved, the potential safety hazard of the bearing high temperature damage risk under different operating conditions is reduced, shortcomings of the existing shafting alignment methodare made up, and ship power safety is improved. The ship propulsion shafting alignment method is used in the field of ship shafting alignment.

Description

technical field [0001] The invention relates to the field of ship shafting alignment, in particular to a ship propulsion shafting alignment method. Background technique [0002] The installation quality and operating status of ship shafting are the foundation of ship power safety, and are highly valued by all parties. The alignment of ship shafting is to install the shafting into a certain state according to certain requirements and methods. In this state, the stress in each shaft section of the shafting and the load on all bearings are within the allowable range or have Reasonable value, so that the shaft system can run reliably. The essence of shafting alignment is to accurately determine the position of the ship's propulsion shafting bearings. The quality of the shafting alignment is crucial to the normal operation of the shafting and the safe and reliable navigation of the ship, especially for the shafting with large shaft diameter, short shafting and small shaft spaci...
