摘　　要：针对一种抽油机曲柄调平衡装置,进行扭矩分析,分别从抽油机上、下冲程电机做功相等,上、下冲程曲柄扭矩峰值相等,曲柄净扭矩均方根值最小三大理论原则出发,推导出3种计算公式,并将公式结果进行比较。最终分析证明,曲柄净扭矩方均根最小原则符合多数情况。Based on the torque analysis of a crank balance device of pumping unit, three calculation formulas are derived from the three principles of equal work done by the motor during up-down stroke, equal peak torque of the up-down stroke and the minimum square mean root value of crank net torque, and the results of the formulas are compared. Finally, it is proved that the square mean root minimum principle of crank net torque is consistent with most cases.
