摘　　要：为使机组的轴系对中状态处于一个较佳的状态,降低轴系不对中对机组振动噪声的影响,在分析了传统对中方法不足的基础上,提出了基于轴心轨迹监测的对中调整方法,该方法综合了考虑机组热态状态的轴承座变形、热胀等因素,可较为准确地反映机组热态运行下轴系的对中状态,实践证明该方法可为机组的热态对中调整起指导作用。同时,分析了其不足之处,并指出后续还需进一步通过试验探索进行完善,以提高其应用精度。In order to make the shafting of state in a better state and to reduce the effect of shaft misalignment of the vibration noise,on the basis of analyzing the deficiency of traditional methods,a shafting alignment method based on orbit monitoring is proposed.The method comprehensively considers the thermal state of the bearing seat deformation,thermal expansion and other factors.It can more accurately reflect shafting status under the unit hot running condition.The practice proves that the method can be used to guide the shafting alignment of the thermal state.Meanwhile,the disadvantages are analyzed and further tests will be done to improve and raise the application accuracy.
