一、前言 滚动轴承在支承机械系统的旋转轴和摆动轴中,是使用得最多的一种轴承。对轴承在现场发生的故障形态进行调查,其结果如图1所示。 图1 滚动轴承故障形态 这些故障形态大致上可分为磨损、烧伤、疲劳剥落和其它等等。在其它一项中包含有振动、噪声和腐蚀等。但是振动和噪声尽管是运转中的故障,却可以认为其大部分是由于磨损和疲劳剥落引起的。 First, the preface Rolling bearings in the supporting mechanical system of the rotating shaft and the swing axis, is the most used type of bearing. Bearings in the field failure occurred in the form of investigation, the results shown in Figure 1. Figure 1 rolling bearing fault morphology These fault morphology can be broadly divided into wear, burns, fatigue spalling and so on. In the other one contains vibration, noise and corrosion. However, vibrations and noises, although troublesome in operation, can be attributed to wear and fatigue spalling.
