分析了链条抽油机轨迹链传动的工作特点;对比了滚子链和新型齿链的技术特性,指出现用加重系列石油滚子链作链条抽油机轨迹链条存在早期失效的严重问题,并就此提出了改进建议;同时推荐用新研制的具有滚动摩擦铰链副的新型齿链取代加重系列石油滚子链作为链条抽油机的轨迹链条。
The characteristics of the chain drive of the chain pumping unit are analyzed. The technical characteristics of the roller chain and the new type of gear chain are compared. It is pointed out that there is a serious problem of the early failure of the chain chain of the chain pumping unit with the heavier series of oil roller chains In this connection, some suggestions for improvement are put forward. At the same time, a new type of gear chain with newly developed rolling friction hinge pair is recommended to replace heavier series of oil roller chain as the chain of chain pumping unit.
