NSK轴承故障在使用过程中具有很强的规律性和重复性。普通you质不锈钢轴承在使用初期振动和噪声小，但频谱分散，振幅小。这可能是由于制造过程中的一些缺点造成的，例如表面毛边。
NSK bearing fault has strong regularity and repeatability in the use process. Ordinary youthful stainless steel bearings h***e low vibration and noise at the initial stage of use, but the frequency spectrum is dispersed and the amplitude is ***all. This may be due to some shortcomings in the manufacturing process, such as surface roughness.
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出现。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，轴承的振动和噪声开始增大，有时NSK轴承故障会出现异常声音，但振动增大到初始故障。
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 exceeding 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 the bearing begin to increase. Sometimes the NSK bearing fault will appear abnormal sound, but the vibration increases to the initial fault.
首先，轴承光谱分析发现铁浓度异常，铁谱图中存在大量铁亚微米磨损颗粒，润滑油的水酸值异常，说明轴承座磨损是由磨损引起的。
Firstly, the bearing spectrum analysis found that the iron concentration was abnormal, there were a large number of iron submicron wear particles in the ferrograph, and the water acid value of lubricating oil was abnormal, which indicated that the wear of bearing seat was caused by wear.
其次，轴承光谱分析发现有色金属元素浓度异常，铁谱中存在大量亚微米级磨损颗粒。润滑油的含水量和酸值过高表明轴瓦表面腐蚀。
Secondly, the bearing spectrum analysis found that the concentration of non-ferrous metal elements was abnormal, and there were a large number of sub-micron wear particles in the ferrography. Excessive water content and acid value of lubricating oil indicate that the bearing surface is corroded.
第三，通过轴承谱分析发现铁浓度异常。铁谱学包含许多亚微米铁粒子。润滑油含水量或酸值过高，说明滚针NSK轴承故障轴颈表面腐蚀。
Thirdly, abnormal iron concentration was found by bearing spectrum analysis. Ferrography contains many submicron iron particles. The excessive water content or acid value of lubricating oil indicates that the surface of the fault Journal of needle roller NSK bearing is corroded.
第四，不锈钢轴承铁谱中含有黑色切削磨料或黑色氧化物颗粒。金属表面回火颜色表明轴承轴颈表面损坏。
Fourth, ferrography of stainless steel bearings contains black cutting abrasives or black oxide particles. The tempering color of the metal surface indicates that the bearing journal surface is damaged.
第五，轴承铁谱中发现切削磨料，磨料成分为有色金属，表明轴承表面损坏。
Fifth, cutting abrasives are found in bearing ferrography, and the abrasive composition is non-ferrous metal, indicating that the bearing surface is damaged.
既然我们知道轴承失效的原因，就应该注意这些方面。不锈钢轴承的使用寿命自然增加。当外部硬颗粒进入轴承并压在轴承体和滚道之间时，表面会产生凹痕。此外，过大的冲击载荷还会导致接触面局部塑性变形，形成凹坑。当NSK轴承故障静止时，即使负载很小，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bu良、灰尘或颗粒物进入轴承或润滑布良时，会造成接触面严重磨损或磨损，增加不锈钢轴承的振动和噪音。
Since we know the cause of bearing failure, we should pay attention to these aspects. The service life of stainless steel bearings increases naturally. When the external hard particles enter the bearing and press between the bearing body and the raceway, the surface will produce dents. In addition, excessive impact load will also lead to local plastic deformation of the contact surface, forming pits. When the failure of NSK bearings is still, even if the load is very ***all, the vibration of the surrounding environment will form a uniform pit on the raceway. When the bearing seal Bu Liang, dust or particulate matter enter the bearing or lubricating cloth Liang, it will cause serious wear or wear of the contact surface, and increase the vibration and noise of stainless steel bearings.
