| 摘 要： | 表面粗糙度对机械密封性能有着显著影响。利用MMU-2摩擦磨损试验机和表面轮廓仪,对3个不同粗糙程度的密封端面进行了摩擦磨损试验。引入特征粗糙度,研究了3个不同粗糙程度的密封端面在摩擦磨损过程中的特征粗糙度变化规律,并与表面的轮廓算术平均偏差粗糙度变化规律进行了比较。研究表明,不同初始粗糙程度的端面在跑合过程结束后,粗糙度趋于一致。这一结果为利用特征粗糙度正确设计机械密封端面,合理选择端面加工方法提供了依据。

| Abstract: | The performance of mechanical seals was influenced significantly by surface roughness.On the MMU-2 friction and wear test machine and the LI-3 type stylus profilometer,three stationary rings with different surface roughness were tested.The law of characteristic roughness change of seal faces with different primary surface roughness was studied during the running-in,and was compared with the law of profile arithmetic average deviation roughness change of surface.The research results show that the roughness o... |
