齿轮箱磨粒在铁谱片上的识别特征

Identifying Character of Wear Particle of Gear Case on the Ferrogram

介绍了铁谱分析的原理、样品的制备方法和铁谱分析的步骤,概括了齿轮箱齿轮、滚动轴承、滑动接触3种主要摩擦副在磨合磨损、正常磨损、异常磨损(过载、过速、疲劳)3个阶段的磨粒的主要识别特征,包括尺寸、尺寸分布、数量、成分和形貌等。

The principle of the ferrography, the ways of the sample preparation and the analyzing process were introduced. The main identifying characters of wear particle on the terrogram such as dimension, distribution, quality, component and form of the wear particle were generalized for the three friction couples of gear case including gear, bearing and sliding contact which is in the different phases of running-in wear,normal wear and abnormal wear and in the different degrees of overload, over-speed and fatigue.
