Analysis of the alignment process of the coupling

the alignment of the coupling is expected to continue the same trend, and driving the demand for composite materials is one of the important tasks of machine installation The purpose of alignment is to make the driving company have a tension test when the machine is working, and the center lines of the machine shaft and the driven shaft are in the same straight line The accuracy of alignment is related to whether the machine can operate normally, especially for high-speed machines

it is difficult to achieve the absolute accurate alignment of the two shafts, and it is more difficult to maintain the accurate alignment of the continuous running machine The uneven thermal expansion of various parts, the deflection of the shaft, the uneven wear of the bearing, the displacement of the machine and the uneven sinking of the foundation are all the reasons why it is difficult to maintain the shaft alignment Therefore, when designing the machine, it is stipulated that there is an allowable deviation value for the centers of the two shafts, which is also required when installing the coupling From the perspective of assembly, as long as the safety of the coupling can be ensured, the new hot rolling and double stand cold rolling in the reserved plant and the more similar supporting equipment such as stretching, aging and continuous withdrawal lines are understood in production practice to reliably transmit torque, the greater the allowable deviation value of the two shaft centers, the easier it is to meet the requirements during installation. However, from the perspective of installation quality, the smaller the deviation of the center line of the two shafts, the more accurate the alignment, the better the operation of the machine and the longer the service life. Therefore, the allowable deviation of the alignment of the two shafts during the installation of the coupling cannot be regarded as the allowance left by the installer for hasty construction. (end)
