Abstract: In the process of installing and overhauling transmission equipment, the alignment and
adjustment of two shafts concentricity is the most important to the equipment that adopting elastic shaft
coupling device. If the way of alignment isn 't right or the value of alignment isn't accurate, it'l cause
transmission error, excessive vibration, abnormal wear and heating, even more the parts of equipment
damaged. In this paper, taking the installation of a large axial flow ventilator as an example, the
influence factor to the measuring method and deviation of the intermediate shaft elastic coupling s
alignment is analyzed by the four table method and triangle amplification method. The alignment
anc
ad ustment method of the intermediate shaft elastic coupling s concen ricity is also introduced in this
paper to guide the installation and alignment of other similar type of large ventilator s elastic couplings
