Embodiment example

[0022] Taking the shafting load measurement process of a ship as an example, the shafting load measurement method based on mechanical measurement

[0023] The implementation instructions are as follows:

[0024] After steps:

[0025] The first step is to fabricate and install the shafting load measuring support tooling.

[0026] In the second step, the hydraulic jack, the load sensor and the arc-shaped pad are sequentially placed on the support tooling from bottom to top.

[0027] The third step is to install a dial indicator on the journal corresponding to the hydraulic jack and the other end of the bearing to be tested.

[0028] The fourth step is to use the hydraulic jack to jack up the shafting in a certain way, and record the corresponding dial gauge readings until the load value does not rise much but the journal continues to rise.

[0029] The fifth step is to release the hydraulic jack according to a certain method, and record the corresponding dial indicator readin...

Abstract

The invention provides a shaft load measurement method based on mechanical measurement. The method is implemented through the first to eighth steps. The method can provide a precise shaft load value for the shaft load alignment. The method effectively improves the shaft load alignment precision. The method can avoid the bearing wear and ship vibration which may be caused by the shaft installation,and guarantees the normal transmission of the power of a main unit. The method is suitable to be used as a shaft load measurement method.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a shafting load measurement method based on mechanical measurement. Background technique [0002] Ship shafting is one of the important power systems of ships. During operation, it is affected by factors such as shafting bending, bearing load and hull deformation, which may cause bearing wear, hull vibration, and reduce the power transmission of the main engine. In order to ensure the continuous normal operation of the shafting of the ship, it is necessary to calculate the alignment of the shafting to distribute the shafting load reasonably, and the measurement of the shafting load is an indispensable process parameter for the alignment of the shafting, so it is necessary to measure the shafting load. research. Contents of the invention [0003] The invention provides a shafting load measurement method based on mechanical measurement. Use a certain method to measure the ...
