In actual production, the equipment load changes little, and the coupling model specification is fixed. So we can create a data model for the coupling. First, the temperature data of the coupling is measured before each overhaul, and the centering error of the coupling is measured during inspection. According to the aforementioned linear law, as long as 3 to 4 data are sufficient (Of course, the data is more The more accurate the judgment will be, draw these data into a linear correlation chart. In this way, after the temperature of the coupling is measured, the centering error of the coupling can be found out from the map, and measures can be taken early to prevent accidents.
