摘　　要：从回转密封表面微观结构的形貌特征出发,对轴类零件回转面的微观构造缺陷有可能引起动力总成类产品内腔的工作介质外泄,从而导致因功能失效而造成严重的质量问题做了详细说明,并着重描述了利用精密的表面轮廓仪,简单实用的悬线法以及白光测量等三种检测方案。It is possible to lead to leak of the powertrain products caused by the defect of microtexture of rotary sealing surface and serious quality problem. This article explains the forming reason of surface twist texture, and introduces the measurement methods making use of precise surface profile instrument, practical string method, white light interferometry. Finally the article declares a way about how to evaluate the rotary sealing surface of twist texture.
