【摘要】 针对传统链条抽油机的平衡机构和换向机构故障率较高、影响生产的问题，设计了一种新型链条抽油机。采用了重力平衡方式和挂钩换向方式，使平衡机构和换向机构极为简单，增加了整机的可靠性。该机不仅保持了传统链条抽油机的长冲程、节能、节材、减速器额定扭矩小等优点，而且克服了原有链条抽油机故障率高、野外适应性差的缺点，具有结构简单、安全可靠、运行平稳等优点。更多还原

【Abstract】 A new chain drive pumping unit was designed to prevent frequent failures of the balance mechanism and the reverse mechanism in traditional chain drive pumping units.Gravity balance mechanism and hook reverse mechanism were adopted to simplify its structure and improve its reliability.更多还原
