| 摘 要： | 对链条抽油机换向机构进行的受力分析表明，由于这种机构设计不合理，其往返架组件在工作载荷作用下受两个方向的弯矩作用，导轮、导轨侧面承受非导向压力，使主传动链条产生严重偏载、侧磨，这是造成换向机构故障率高的根本原因。针对换向机构存在的问题，提出了在往返架上添加侧向导轮，调整往返架上平衡力作用点，采用两挂主传动链同步运转并加关节轴承等改进建议。

| Abstract: | Force analysis of the reverse mechanism now commonly adopted on chain-drive pumping units shows that,due to the unreasonable design of the mechanism,serious eccentric lOading and side abrasion occur on the main drive chain.Suggestions for improvement are put forward,as attaching lateral guide pulley on the reciprocating rack, adjusting the acting point of the balancing force on the reciprocating rack,applying synchronous drive with two ban drive chains and adding oscillating bearing. |
