泰州NSK轴承在使用过程中表现出较强的规律性和重复性.普通优*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 NSK bearings show strong regularity and repeatability in the use process. The vibration and noise of ordinary high quality stainless steel bearings are relatively small in the initial stage of service, but the spectrum is dispersed and the amplitude is small. This may be due to some defects in the manufacturing process, such as su-ce 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.

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.

连续运行后,泰州NSK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 continuous operation, the vibration and noise of Taizhou NSK bearing begin to increase, sometimes abnormal sound occurs, but the vibration increases to the initial failure.

首先,轴承光谱分析发现有色金属元素浓度异常.在铁谱学中出现了许多亚微米的有色金属磨粒.润滑油含水量过高和酸值表明轴承套筒的存在.表面被腐蚀了.

Firstly, the bearing spectrum analysis found that the concentration of non-ferrous metal elements was abnormal. Many sub-micron abrasive grains of non-ferrous metals have appeared in ferrography. Excessive water content and acid value of lubricating oil indicate the existence of bearing sleeve. The su-ce was corroded.

其次,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,润滑油水分和酸值异常,表明轴承背部为微动磨损.

Secondly, bearing spectrum analysis found that iron content was abnormal, ferrography contained a large number of submicron iron abrasives, lubricating oil moisture and acid value were abnormal, indicating that the back of the bearing was fretting wear.

第三,不锈钢轴承的铁谱分析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泰州NSK轴承轴颈表面受到损伤.

Thirdly, ferrographic analysis of stainless steel bearings contains black cutting abrasive particles or black oxide particles, and the tempering color of the metal su-ce indicates that the journal su-ce of Taizhou NSK bearings is damaged.

第四,在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.

Fourthly, cutting abrasives are found in bearing ferrography. The abrasive composition is a non-ferrous metal, indicating that the bearing su-ce is damaged.

第五,轴承光谱分析发现铁浓度异常,存在大量亚微米铁颗粒,润滑油水分或酸值超标,表明滚针轴承的轴颈表面被腐蚀.

Fifth, bearing spectrum analysis found that iron concentration was abnormal, there were a large number of submicron iron particles, lubricating oil moisture or acid value exceeded the standard, indicating that the journal su-ce of needle roller bearings was corroded.

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.

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.

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.当泰州NSK轴承静止时,即使载荷很小,周边环境的振动也会在滚道上形成均匀的凹坑.

When external hard particles enter the bearing, there will be dents on the su-ce between the extruder body and the raceway. In addition, excessive imPACt load can also cause local plastic deformation of the contact su-ce and form pits. When Taizhou NSK bearings are stationary, even if the load is small, the vibration of the surrounding environment will form uniform pits on the raceway.

当轴承密封不*良、灰尘或颗粒物质进入轴承或润滑不*良时,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 seal is not good, dust or particulate matter enters the bearing or lubrication is not good, it will cause serious wear on the contact su-ce, and increase the vibration and noise of stainless steel bearing.
