旋转驴头抽油机的驴头设计

Horsehead Design of Rotating Horsehead Pumping Unit

摘要: 通过几何分析详细推导出了旋转驴头抽油机驴头弧面理论节线计算的极坐标公式，并给出了计算该抽油机冲程长度的两种计算方法，最后介绍了驴头侧板的两种下料方法及驴头剖分成主、副驴头的设计原理。

Abstract: Formulas used to calculate the theoretical pitch line of pumping unit horsehead and two methods for computing the stroke of pumping unit are derived through geometric analysis.This paper introduces the methods to manufacture the side panels of pumping unit and the design principles of the main and auxiliary horseheads.
