| 摘 要： | 为减少抽油杆与油管之间的偏磨,建立了收敛楔形间隙在杆管间的液体动压润滑数学模型,依据雷诺方程导出了油膜压力的计算公式,分析了影响油膜力大小的因素.结果表明:在收敛楔形间隙某一高度处,油膜压力沿圆周方向的分布是在间隙最小处油膜压力最大,在间隙最大处油膜压力最小;收敛楔形间隙在某一偏角处,沿轴向方向,随轴向高度的增大,油膜压力逐渐增大,增大到一定数值,油膜压力又逐渐减小.

| Abstract: | To reduce the deviating-friction between sucker rod and tubing,an analytical model of hydrodynamic pressure lubrication using convergent wedgelike gap of rod and tubing was derived.Oil film pressure was obtained based on the Reynolds equation,and the main factors influencing on the oil film pressure were analyzed.The results show that at certain heigh of convergent wedgelike gap,oil film pressure distribution along the circular path is various.The maximum oil film pressure is located at the least gap,and th... |
