摘　　要：抽油机载荷的波动性是造成电动机效率降低和轴功率过高的最主要原因,也直接导致了抽油机能耗过高。根据游梁结构和摇块机构,设计了新型游梁式摇块机构抽油机的传动机构,使抽油机的载荷曲线呈微小波动形态,提高了电动机效率,降低了电动机的轴功率,实现了抽油机的高效节能。建立了传动机构的运动和动力学数学模型,以MATLAB优化工具箱为平台,对传动机构进行全参数优化设计,并以实际载荷工况对抽油机的性能和节能效果进行了对比分析。Load fluctuation of the pumping units is the main reason of low efficiency and high shaft power of motor and these two drawbacks cause high energy consumption. Based on the beam structure and rocker mechanism, a redesigned pumping unit mechanism is developed and is doing well in diminishing the load fluctuation, maximized the motor efficiency and minimizes motor shaft power. Thus, a high transmission mechanism efficiency of pumping unit with low energy consumption is made possible. All parameters optimizing design and effectiveness of energy saving are made and analyzed with a mathematic model of kinematics ＆ dynamics based on the system of MATLAS optimization toolbox.
