摘　　要：[目的]针对游梁式抽油机存在系统效率低、能耗高、负载波动大的不足,对基于非圆齿轮传动的游梁式抽油机节能设计方案进行研究.[方法]在考虑非圆齿轮传动条件及其与曲柄载荷匹配原则的基础上,选取最优非圆齿轮节曲线,形成非圆齿轮节曲线的节能设计准则.通过仿真分析,获得不同非圆节曲线对应的能耗值,筛选出最低能耗对应的非圆节曲线,并结合CYJY10-4.2-53HB型号游梁式抽油机进行仿真和实验验证.[结果]1)仿真结果得到在同功率电机下耗能降低4.7%,在更小功率电机下耗能降低11%,与实验结果基本一致;2)基于非圆齿轮传动的游梁式抽油机,可大幅度降低抽油机输入轴的扭矩峰值和扭矩波动,降低能耗,实现节能.[结论]从节能和降低负载波动的角度来看,非圆齿轮传动对于圆柱齿轮更有优势.[Objective]Amid the background of carbon peak and carbon neutrality strategy,it is particularly critical to study the oil-production technology with low energy consumption,high efficiency and green environmental protection characteristics.As a type of oil production equipment with simple structure,high stability and strong environmental adaptability,the beam pumping unit has been widely used in the oil field exploitation.However,a shortage of low system efficiency and high energy consumption remains.In view of the energy-saving technical problem of beam pumping unit,this paper presents a beam pumping unit energy-saving design method based on non-circular gear transmission.[Methods]In the original state equipment,the output power of the motor needs to be selected according to the peak load,which cannot adapt to the fluctuation of the load,thus resulting in low matching degree between the motor and the load,also resulting in large energy consumption.However,for the new non-circular gear structure,the crank angle speed can vary appropriately according to the load due to the variability of the gearbox speed and acceleration.Based on the generated tooth shape data,the gear drawing is obtained,and the non-circular gear is manufactured by cutting the slow moving wire.[Results]Simulation results show that the peak load of the motor is reduced from 317.3 N·m to 238.3 N·m,decreasing by 24.9%,and that the requirment of changing 37 kW motor to 30 kW motor is met.At the optimal crank angular speed,the energy consumption of 37 kW original state structure motor is 52493 J;the energy consumption of 37 kW non-circular structure motor is 50044 J;the energy consumption of 30 kW non-circular motor is 46722 J.Under the same power of 37 kW motor,the energy saving rate is 4.7%.After 30 kW motor is used,the energy saving rate is 11.0%.After non-circular gear transmission is used,the energy saving effect of beam pumping unit appears remarkable.The designed active pitch curve formula is used to obtain the change curve of curvature and a
