6、一、题目来源背景 滚动轴承是各种旋转机械中应用最广泛的一种通用部件，也是机械设备中最容易损坏的部件之一，它的运行状态是否良好会直接影响到整台机器的性能，如精度、可靠性及寿命等。就旋转机械而言，据统计，现场实际故障中 30%是由于滚动轴承故障引起的。这是因为滚动轴承是机械设备中工作条件最为恶劣的部件，它在机械设备中起着承受载荷和传递载荷的作用。所以滚动轴承的故障诊断方法一直是机械故障诊断中重点发展的技术之一。因此对滚动轴承的故障诊断和预测已经成为各国研究的热点。 滚动轴承的工况监测与故障诊断在国外大概开。

9、摘 要 - I - 摘 要 滚动轴承是旋转机械中应用最广泛的一种通用部件，也是机械设备中的易损零件，许多机械的故障都与滚动轴承的状态有关。据统计，在使用滚动轴承的旋转机械中，大约 30的机械故障是由于滚动轴承的损坏造成的。可见，滚动轴承的好坏对机械系统工作状况的影响极大。由于设计不当和安装工艺不好或轴承的使用条件不佳，或突发载荷的影响，使轴承运转一段时间后会产生各种各样的缺陷，并且在继续运行中进一步扩大，使轴承运行状态发生变化。因此，滚动轴承的故障诊断一直是研究的热点。 本文首先从理论上分析了滚动轴承的失效形。
