摘要: 介绍平面连杆系统在机构综合中的基本方法,确定机构与连杆系统的对应关系,采用该方法对有杆式抽油机增程机构进行了综合,构造出多种有杆式抽油机增程机构和相应的平面连杆系统,用以增加抽油机的冲程和改进抽油机增程机构的设计.针对综合后的抽油机各个增程机构设计方案,作了受力分析和冲程计算,推导出了抽油杆增程系数和连杆驱动力增力系数计算式,最后在多种综合设计方案中确定出一种较好的机械增程机构.旨在为采油机械设计者提供一种有杆式抽油机的创造性设计方法和多种可行的增程机构.

Abstract: A mechanical synthesis method of the systematical linkages for the stroke-increasing mechanism of rod pumping units is introduced in this paper,the corresponding relations between the components in the mechanism and the link-elements in the systematical linkages are determined.The rod pumping unit is synthesized,and several mechanisms and associate linkages for increasing the stroke of the rod pumping units are created.In the light of every synthesis mechanism,the analyses of working loads and calculation of stroke are conducted,and the formula are derived to calculate the force-increasing factors and stroke-increasing ones.Finally,a better mechanism for the stroke-increasing is chosen.

Key words: systematical linkage, synthesis, rod pumping unit, stroke-increasing, mechanism
