Study on centering technology of two large-scale rotating machinery coupling shaft axis

This paper studies the centering accuracy of two large-scale rotating machinery coupling shaft. Laser LD and position sensitive sensors PSD are used to measure and adjust the centering of two shaft coupling, through the analysis of LD-double-PSD-angle prism, LD-double-PSD-plane mirror of the double LD-double-PSD, dual-LD-double PSD centering program, it established a double LD-double -PSD system mathematical model, and the computer simulations to get good results. Based on the theoretical results, the two axes large-scale rotating machinery LD-link LD-double-PSD centering system has been studied and designed.
