尾部滑动平衡抽油机滑动机构运动分析

Movement analysis on balance machine of beam pumping unit with rear balance methods

游梁尾部滑动平衡节能抽油机是在游梁尾端增加一个相连接的三杆滑动机构,滑块重心的运动是复合运动,笔者根据机构几何关系和运动特点,建立运动学模型,进而给出滑块重心的运动参数的计算方法。

The beam pumping unit introduced is a new saving energy one with rear balance methods which a balance machine is fixed on rear of beam. The balance body glides on the balance machine when beam pumping unit runs. The movement of balance body is multiple. Based on the geometry relation and movement character, the kinematics model is found. And then its calculation method for the movement parameter of balance body is given in the paper.
