摘　　要：运用耦合器液力传动原理, 研制成功抽油机耦合器传动系统。该系统把传统的抽油机胶带传动改变为齿轮硬性传动, 彻底克服了因胶带传动而造成的抽油机传动效率低、电动机过载被烧毁, 以及因惯性载荷造成抽油机的冲击和振动等弊端, 实现了传动最优化。现场应用测试表明: (1) 耦合器传动系统可改善抽油机启动和传动中的软特性, 提高整机和抽油杆的使用寿命;(2) 解决了抽油机胶带传动中打滑“丢转”和频繁更换胶带等问题; (3) 实现了抽油机大传动比, 冲次任意可调, 从而满足供液不足油井和稠油注蒸汽生产井的不同需要; (4) 可提高抽油机系统效率 2 24%, 日耗电量下降 39 6%。A coupler drive system for pumping unit is developed by using the theory of hydraulic drive of coupler. The new drive system adopts gear drive instead of the traditional rubber belt transmission, therefore realizes optimum transmission of pumping unit by overcoming the disadvantages of the belt transmission. Field use and test shows that, (1) the coupler drive system improves the soft characteristics in the starting and transmission of the pumping unit; (2) the new drive system solves the problems of drive slippage and frequent change of rubber belt; (3) it provides large transmission rate and enables adjusting the stroke number optionally; (4) the system efficiency of the pumping unit can be improved and power consumption can be lowered by using the coupler drive system.
