INA轴承故障预防在使用过程中具有很强的规律性和重复性。品质优良的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，例如表面粗糙度。

INA bearing fault prevention has strong regularity and repeatability in the use process. Stainless steel bearings with good quality have low vibration and noise at the initial stage of service, but the frequency spectrum is dispersed and the amplitude is small. 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。频率超过三个频率的情况很少发生。不锈钢轴承处于非常稳定的状态，进入稳定的工作循环。

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.

连续运行后，轴承的振动和噪声开始增大，有时会出现异常声音，但振动增大到初始故障。

After continuous operation, the vibration and noise of the bearing begin to increase, sometimes abnormal sound will appear, but the vibration increases to the initial fault.

首先，轴承光谱分析发现，有色金属元素浓度异常，INA轴承故障预防铁谱中出现大量有色金属成分的亚微米磨损颗粒。润滑油的含水量和酸值过高表明轴承表面受到腐蚀。

First of all, bearing spectrum analysis found that the concentration of non-ferrous bl elements is abnormal, INA bearing fault prevention ferrography appears a large number of sub-micron wear particles of non-ferrous bl components. Excessive water content and acid value of lubricating oil indicate that the bearing surface is corroded.

其次，轴承光谱分析发现铁浓度异常，铁谱中存在亚铁亚微米磨损颗粒，润滑油的水酸值异常，说明轴承磨损是由微动引起的。

Secondly, bearing spectrum analysis found that iron concentration was abnormal, ferrous submicron wear particles existed in ferrography, and water acid value of lubricating oil was abnormal, which indicated that bearing wear was caused by fretting.

第三，不锈钢轴承的铁谱中含有黑色切削磨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损坏。

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

第四，INA轴承故障预防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。

Fourthly, cutting abrasives are found in INA bearing failure prevention ferrography. The abrasive comb is non-ferrous bl, indicating that the bearing surface is damaged.

第五，轴承光谱分析发现，铁的异常浓度，存在许多亚微米铁颗粒，润滑油水分或酸值超标，说明滚针轴承的轴颈表面受到腐蚀。

Fifth, bearing spectrum analysis found that the abnormal concentration of iron, there are many submicron iron particles, lubricating oil moisture or acid value exceeded the standard, indicating that the journal surface of needle roller bearings was corroded.

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。

Since we know the cause of bearing failure, we should pay attention to these aspects. The service life of stainless steel bearings increases naturally.

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INA轴承故障预防静止时，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。

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 debation of the contact surface, bing pits. When INA bearings fail to prevent static, even if the load is small, the vibration of the surrounding environment will b a unib pit on the raceway.

当轴承密封bu良、灰尘或颗粒物进入轴承或润滑bu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。

When the bearing seal Bu Liang, dust or particulate matter enter the bearing or lubrication Bu Liang, it will cause serious wear or wear of the contact surface, and increase the vibration and noise of stainless steel bearings.

在检查之前，应清洁机器表面，并拆下轴承周围的零件。油封是非常脆弱的零件，需要仔细拆卸，不要用力过大，然后仔细检查油封及其周围零件，如果有bu良症状，bi须更换，bu良的油封会导致轴承损坏，并严格关闭设备。

Before inspection, the machine surface should be cleaned and the parts around the bearing should be removed. Oil seals are very fragile parts, need to be carefully removed, not too hard, and then carefully inspect the oil seals and their surrounding parts, if there are good symptoms of bu, Bi must be replaced, Bu good oil seals will lead to bearing damage, and strict closure of equipment.

检查INA轴承故障预防润滑油，用手指间的少许油擦拭。如果有任何污染物，你可以感觉到它，或者在你的手背上涂一层薄薄的润滑剂，然后关灯。

Inspect INA bearing failure to prevent lubricating oil, wipe with a little oil between fingers. If there is any contaminant, you can feel it, or put a thin layer of lubricant on the back of your hand, and turn off the light.
