摘　　要：高转差率电动机和变速控制技术是游梁式抽油机"降载节能"的重要措施之一。抽油机变速运行时,惯性载荷所占总载荷的比例增大。对游梁式抽油机关键节点电机和曲柄处的转动惯量进行了分析,结果表明:转动惯量的变化对电动机轴转矩影响幅度最大,对悬点载荷影响最小。The high-slip motor and variable-velocity controlling technology are the important technology measures for load shedding and saving-energy of beam pumping units.When the pumping unit was operated with variable-velocity,the inertial load had bigger proportion in the total load.In this paper,a theoretical calculation was used to analysis the influence of rotational inertia at motor output shaft and gearbox output shaft to the key nodes of beam pumping units.The results indicated that the rotational inertia had the biggest influence to the torque of motor output shaft,and the smallest influence to the polished rod load.
