摘　　要：分别从轴承的几何形状偏差、粗糙度、偏斜量及润滑时的膜厚比来分析计算出燃气轮机发电机组转子需要被顶起的高度值。在项目安装调试时,将顶轴油系统压力提升至要求的范围内,并反复调试“机端”与“励端”的油囊压力值与顶起的高度值,最终调试出合适的参数。To analyze and calculate the height value at which the gas turbine generator rotor needs to be lifted based on the geometric deviation,roughness,deflection value,and oil film thickness ratio of the bearing during lubrication.During the installation and debugging of the project,increase the pressure of the jacking oil system to the required range,and repeatedly adjust the oil chamber pressure values and jacking height values of the“machine end”and“excitation end”to finally debug appropriate parameters.
