泰州NSK軸承在使用過程中表現(xiàn)出較強(qiáng)的規(guī)律性和重復(fù)性,。普通優(yōu)*質(zhì)不銹鋼軸承在服役初期振動(dòng)和噪聲相對(duì)較小，但頻譜分散,，振幅小,。這可能是由于制造過程中的一些缺*點(diǎn)，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.

經(jīng)過一段時(shí)間的運(yùn)動(dòng),，振動(dòng)和噪聲保持在一定的水平，頻譜非常單一,，只有頻率的一到兩倍,。超過三個(gè)頻率的頻率很少發(fā)生。不銹鋼軸承處于非常穩(wěn)定的狀態(tài),，進(jìn)入穩(wěn)定的工作循環(huán),。

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.

連續(xù)運(yùn)行后，泰州NSK軸承的振動(dòng)和噪聲開始增加,，有時(shí)會(huì)發(fā)生異常聲音,，但振動(dòng)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,，軸承光譜分析發(fā)現(xiàn)有色金屬元素濃度異常,。在鐵譜學(xué)中出現(xiàn)了許多亞微米的有色金屬磨粒。潤(rùn)滑油含水量過高和酸值表明軸承套筒的存在,。表面被腐蝕了,。

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，軸承譜分析發(fā)現(xiàn)鐵含量異常,，鐵譜中含有大量的亞微米鐵磨料,，潤(rùn)滑油水分和酸值異常，表明軸承背部為微動(dòng)磨損,。

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,，不銹鋼軸承的鐵譜分析含有黑色切削磨料顆粒或黑色氧化物顆粒,，金屬表面的回火顏色表明泰州NSK軸承軸頸表面受到損傷,。

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，在軸承鐵譜中發(fā)現(xiàn)切削磨料,。磨料組合物為有色金屬,，表明軸承表面受損。

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,，軸承光譜分析發(fā)現(xiàn)鐵濃度異常,，存在大量亞微米鐵顆粒,，潤(rùn)滑油水分或酸值超標(biāo)，表明滾針軸承的軸頸表面被腐蝕,。

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.

現(xiàn)在我們知道軸承失效的原因,，我們應(yīng)該注意這些方面。不銹鋼軸承的使用壽命自然會(huì)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.

當(dāng)外部硬質(zhì)顆粒進(jìn)入軸承時(shí),，擠出機(jī)本體和滾道之間的表面會(huì)有凹痕。此外,，過大的沖擊載荷也會(huì)引起接觸表面的局部塑性變形并形成凹坑,。當(dāng)泰州NSK軸承靜止時(shí)，即使載荷很小,，周邊環(huán)境的振動(dòng)也會(huì)在滾道上形成均勻的凹坑,。

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.

當(dāng)軸承密封不*良、灰塵或顆粒物質(zhì)進(jìn)入軸承或潤(rùn)滑不*良時(shí),，會(huì)在接觸面上造成嚴(yán)重的磨損,，增加不銹鋼軸承的振動(dòng)和噪聲。

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.
