镇江INA轴承NA4911故障的易损化零件的诊断

滚动轴承是应用广泛的机械零件之一，也是易损坏的零件之一。许多旋转机械的故障都与滚动轴承的状态有关。据统计，滚动轴承米尔斯滚动轴承的机械故障约30个百分点是由轴承引起的。由此可见，轴承的质量对机床的工作状态有很大的影响。

Rolling bearing is one of the widely used mechanical parts, and also one of the easily damaged parts. The faults of many rotating machines are related to the state of rolling bearings. According to statistics, about 30 percent of the mechanical failures of mills rolling bearings are caused by bearings. It can be seen that the quality of the bearing has a great influence on the working state of the machine tool.

通常，由于轴承的缺点，机器会产生振动和噪音，甚至损坏机器。在高精度机械（如高精度机床主轴、陀螺仪等）中，对镇江INA轴承的要求较高，即使轴承存在微米级的缺点，也会导致整个机械系统的精度被***。

Usually, due to the shortcomings of bearing, the machine will produce vibration and noise, or even damage the machine. In high-precision machinery (such as high-precision machine tool spindle, gyroscope, etc.), Zhenjiang INA bearings are highly demanded. Even if the bearings h***e micron-level shortcomings, the accuracy of the entire mechanical system will be destroyed.

早的轴承诊断方法是将听力杆与轴承位置接触，根据听力来判断轴承是否失效。这种方法仍在使用，但***已逐渐取代杆，以提高灵敏度。随后，镇江INA轴承各种振动测量仪器逐渐被用来根据位移、速度或加速度的均方根值或峰值来判断轴承是否故障。这可以减少对设备维护人员的经验的依赖，但仍然难以检测早期故障。

The early bearing diagnosis method is to contact the hearing rod with the bearing position and judge whether the bearing is invalid according to the hearing. This method is still in use, but stethoscope has gradually replaced rods to improve sensitivity. Subsequently, various vibration measuring instruments of Zhenjiang INA bearing are gradually used to judge whether the bearing is faulty according to the root mean square value or peak value of displacement, velocity or acceleration. This can reduce the reliance on the experience of the equipment maintainers, but it is still difficult to detect early failures.

滚动轴承在设备中取得广泛应用。滚动镇江INA轴承的状态直接关系到旋转设备的运行状态。尤其在大型连续生产企业中，滚动轴承被广泛应用于大型旋转设备的重要部件。理论基础的重要环节。经过长期的实践和探索，我们积累了一些实用的滚动轴承故障诊断技术。

Rolling bearings are widely used in equipment. The state of rolling INA bearings in Zhenjiang is directly related to the running state of rotating equipment. Especially in large-scale continuous production enterprises, rolling bearings are widely used in the important parts of large-scale rotating equipment. The important link of theoretical foundation. After a long period of practice and exploration, we h***e accumulated some practical fault diagnosis techniques for rolling bearings.

滚动轴承故障诊断方法及要点

Methods and key points of rolling bearing fault diagnosis

振动分析是滚动轴承状态监测和故障诊断的一种实用方法。

Vibration analysis is a practical method for condition monitoring and fault diagnosis of rolling bearings.

在实际应用中，应注意测量点的位置和采集方法的选择。为了真实、准确地反映滚动镇江INA轴承的振动状态，须注意采集到的信号是否准确、真实。因此，有必要将测量点放置在离轴承靠近的地方，并且通常在电机的某一端有一个后风扇盖。测量点的选择对风机壳体固定螺栓的监测有良好的效果。此外，振动信号的采集和分析须综合比较。可以得出准确的结论。

In practical application, we should pay attention to the location of measuring points and the choice of acquisition methods. In order to truly and accurately reflect the vibration state of rolling Zhenjiang INA bearing, it is necessary to pay attention to whether the collected signals are accurate and true. Therefore, it is necessary to place the measuring point close to the bearing and usually h***e a rear fan cover at one end of the motor. The selection of measuring points has a good effect on the monitoring of the fixed bolts of the fan housing. In addition, the acquisition and analysis of vibration signals must be compared comprehensively. Accurate conclusi*** can be drawn.
