摘要
在分析橡胶材料干摩擦和水润滑摩擦两种摩擦机理的基础上,采用INSTRON高频疲劳试验机对O形密封圈在这两种状态下的摩擦力进行了测试。试验获得了不同滑移速度下摩擦系数与载荷的关系以及不同载荷下摩擦系数与滑移速度之间的关系。结果表明:水润滑状态下由于密封接触面能够形成润滑水膜,摩擦力较小,更适合长期稳定运转。
Experimental results of O-ring frictional force under dry friction and water lubrication were obtained using INSTRON,based on knowing the principle of dry friction and water lubrication.The relationship of frictional coefficient with load and sliding speed was analyzed.The results indicated that water film could be developed between contacting surfaces under water lubrication,which led to less frictional force and stability of performance.
