摘　　要：在大型往复式压缩机安装调试及大修过程中,机组联轴器的对中找正是一项十分重要的工作。联轴器的对中找正能消除各轴在联轴器处附加干扰的机械应力,使机组的各轴心线达到同轴的要求[1],况且机组在经过大修后,机械磨合时各轴还可以维持合理的对中状态,保证机组平稳正常、长期地连续工作。联轴器对中找正的质量能直接影响机器效能发挥的程度以及机组的使用寿命。如果机组各轴对中找正质量差,会使机组投产运行时发生较大振动,并且会磨损轴瓦、曲轴等转动构件,更严重时会导致机组损坏。During the installation,commissioning and overhaul of large reciprocating compressor,the alignment of unit coupling is a very important work.The alignment of the coupling can eliminate the mechanical stress of the additional interference of each shaft at the coupling,so that each shaft centerline of the unit can meet the requirements of coaxiality[1].Moreover,after the unit is overhauled,each shaft can still maintain a reasonable alignment state during mechanical running-in,to ensure the stable,normal and long-term continuous operation of the unit.The quality of coupling alignment can directly affect the performance of the machine and the service life of the unit.If the alignment quality of each shaft of the unit is poor,it will cause large vibration when the unit is put into operation,and it will wear the bearing bush,crankshaft and other rotating components,and even more serious,it will cause damage to the unit.
