运行中泰州INA轴承RNA4856出现故障的应变方法

泰州INA轴承在使用过程中表现出较强的规律性和重复性。普通优*质不锈钢轴承在服役初期振动和噪声相对较小，但频谱分散，振幅小。这可能是由于制造过程中的一些缺点，如表面毛刺。

Taizhou INA bearings show strong regularity and repeatability in the use process. The vibration and noise of ordinary high quality stainless steel bearings are relatively ***all in the initial stage of service, but the spectrum is dispersed and the amplitude is ***all. This may be due to some shortcomings in the manufacturing process, such as surface burrs.

经过一段时间的运动，振动和噪声保持在一定的水平，频谱非常单一，只有频率的一到两倍。超过三个频率的频率很少发生。不锈钢轴承处于非常稳定的状态，进入稳定的工作循环。连续运行后，泰州INA轴承的振动和噪声开始增加，有时会发生异常声音，但振动增加到初始失效。

After a period of movement, the vibration and noise remain at a certain level, the spectrum is very single, only one or two times the frequency. Frequencies over three frequencies rarely occur. Stainless steel bearings are in a very stable state and enter a stable working cycle. After continuous operation, the vibration and noise of INA bearing in Taizhou begin to increase, sometimes abnormal sound occurs, but the vibration increases to the initial failure.

首先，轴承谱分析发现铁含量异常，铁谱中含有大量的亚微米铁磨料，润滑油酸值异常，表明轴承背面磨损为微动磨损。

Firstly, bearing spectrum analysis found that iron content was abnormal, ferrography contained a large number of sub-micron iron abrasives, and acid value of lubricating oil was abnormal, indicating that the wear on the back of bearing was fretting wear.

其次，轴承光谱分析发现有色金属元素浓度异常。铁谱中亚微米磨料较多，润滑油中含水量过高，酸值过高，表明有色金属中含有亚微米磨料。瓷砖表面腐蚀。

Secondly, the bearing spectrum analysis found that the concentration of non-ferrous metal elements was abnormal. There are more submicron abrasives in ferrography, too high water content in lubricating oil and too high acid value, which indicates that there are submicron abrasives in non-ferrous metals. The surface of ceramic tile is corroded.

第三，泰州INA轴承光谱分析发现铁浓度异常。铁谱中有许多亚微米铁粒子。润滑油含水量过高或酸值过高表明滚针轴承的轴颈表面受到腐蚀。

Thirdly, the spectrum analysis of INA bearing in Taizhou found that the iron concentration was abnormal. There are many submicron iron particles in ferrography. Excessive water content or acid value of lubricating oil indicates that the journal surface of needle roller bearings is corroded.

第四，不锈钢轴承的铁谱图中含有黑色切削磨料颗粒或黑色氧化物颗粒，金属表面的回火颜色表明轴承轴颈表面受到损伤。

Fourthly, the ferrography of stainless steel bearings contains black cutting abrasive particles or black oxide particles, and the tempering color of the metal surface indicates that the bearing journal surface is damaged.

第五，在泰州INA轴承铁谱中发现切削磨料。磨料组合物为有色金属，表明轴承表面受损。

Fifth, cutting abrasives were found in the ferrography of INA bearing in Taizhou. The abrasive composition is a non-ferrous metal, indicating that the bearing surface is damaged.

现在我们知道轴承失效的原因，我们应该注意这些方面。不锈钢轴承的使用寿命自然会增加。当外部硬质颗粒进入轴承时，挤出机本体和滚道之间的表面会有凹痕。此外，过大的冲击载荷也会引起接触表面的局部塑性变形并形成凹坑。

Now that we know the cause of bearing failure, we should pay attention to these aspects. The service life of stainless steel bearings will naturally increase. When external hard particles enter the bearing, there will be dents on the surface between the extruder body and the raceway. In addition, excessive impact load can also cause local plastic deformation of the contact surface and form pits.

当轴承静止时，即使载荷很小，周围环境的振动也会在滚道上形成均匀的凹坑。当轴承密封不当、灰尘或颗粒物质进入轴承或润滑不顺畅时，会在接触面上造成严重的磨损，增加不锈钢轴承的振动和噪声。

When the bearing is stationary, even if the load is ***all, the vibration of the surrounding environment will form a uniform pit on the raceway. When improper seal, dust or particulate matter enter the bearing or lubrication is not ***ooth, it will cause serious wear on the contact surface, increase the vibration and noise of stainless steel bearings.
