监测滚动轴承完整性的最成熟的技术是振动分析。然而，在极低的旋转速度下，监测滚动元件轴承的健康状况充满困难。本工作的第一部分详细介绍了监测速度低于2 rpm的滚动轴承的困难。此外，它提出了一个研究的高频声发射（AE）技术作为一种手段，监测低速滚动轴承。应用声发射监测运行的低速轴承内径为120毫米。得出的结论是，AE产生的机制是经历机械完整性损失的轴承元件之间的相对运动，例如，滚子在有缺陷的外圈上的滚动/滑动动作。(C)2002爱思唯尔科技有限公司版权所有。
The most established technique for monitoring the integrity of rolling element bearings is vibration analysis. However, at extremely slow rotational speeds monitoring the health of rolling element bearings is fraught with difficulty. Part I of this work details difficulties with monitoring rolling element bearings rotating at speeds of less than 2 rpm. Furthermore, it presents a study of the high frequency acoustic emission (AE) technique as a means of monitoring low-speed rolling element bearings. The application of AEs to monitor operational slow-speed bearings with bore diameters of 120 mm is presented. It is concluded that the mechanism of AE generation was the relative movement between bearing elements experiencing loss of mechanical integrity, for example, the rolling/sliding action of a roller on a defective outer race.
